UK. Rolls-Royce gets funding to develop mini nuclear reactors:
In 2019, China had a new target of 200 GWe of nuclear generating capacity by 2035, which is 7.7% out of predicted total electricity generating capacity of 2600 GWe.
https://en.wikipedia.org/wiki/Nuclear_power_in_China
So with about 50 GWe from 50 reactors today adding another 150 gives you the same goal of about 200 GWe. Unless we're talking SMRs because then the goal just got reduced to a fraction of the original.

(Lazard’s latest annual Levelized Cost of Energy Analysis (LCOE 15.0) shows the continued cost-competitiveness of certain renewable energy technologies on a subsidized basis and the marginal cost of coal, nuclear and combined cycle gas generation.)
When probed on how to address intermittency, many wind and solar advocates propose things like hydrogen storage, giant flywheels, compressed air, or other solutions that are currently in the prototyping stage and have yet to actually be deployed to a grid and demonstrate viability.
This is the chief advantage of nuclear power: it works and we have over half a century of production experience with it. Betting on one of those storage solutions panning out is betting on a big unknown.

Lithium ion battery production is at only ~400 GWh per year. By comparison, the US uses 12,500 TWh of electricity daily, or just over 500 GWh per hour. And this is only electricity, not total energy usage. Attempting to provision widespread lithium ion storage would lead to demand shock and skyrocketing prices. Not to mention it would involve delaying transition from ICE vehicles to EVs.
You're right in some scenarios: if a country has extensive dam networks, then yes renewables + storage could be cheaper. Dams provide immense energy storage capacity. Close the turbines when solar and wind are producing, open them when they're not. If a country is blessed with extensive hydroelectric potential then great.
But hydroelectricity is a matter of geography, and plenty of regions do not have the right geography to construct dams. Lithium ion battery storage is not cheaper than nuclear, and is not produced at sufficient scale to be viable for grid storage. Other proposals like hydrogen storage, flywheels, etc. have not actually been deployed to the grid so we have no real-world cost history for these systems. Somebody writing a white paper claiming $X/KWh of storage and actually building a system are two very different things.
You're simplifying out that electric consumption varies during the day.
Browsing the last day's energy usage yields peaks at:
Eastern: 8pm
Central: 7pm
Mountain 6pm
Pacific: 5pm
It may not be so now, but in 7 years, or in other words, by the time a nuclear power plant commissioned today starts producing power, it definitely will.
Global li-ion manufacturing capacity is poised to triple by 2024:
https://www.luxresearchinc.com/blog/li-ion-manufacturing-in-...
Without a sudden, disruptive change in the cost and rate of deployment of nuclear there doesn't exist a path for it become a significantly larger part of the energy mix.
But we need all of that to electrify transportation, so where do you get the ones for the power grid?
Also, what happens to the price of batteries if you get rid of baseload and cause demand for batteries to spike much higher than even the increased amount of battery production capacity?
It's also ignoring that electricity usage is predicted to increase substantially worldwide as countries develop, and that these predictions of lithium ion battery production might not pan out. It'd also severely delay adoption of electric vehicles, as battery capacity is being diverted to grid storage away from EVs.

Still nuclear can be useful if some country are able to build them fast enough and cheap enough.
Your Storage does only need to be for 1-2 days (or more precisely until your renewables come online again to recharge them).
I don't see a massive shift to battery manufacturing any more crazy than building a crazy amount of nuclear power plants.
Even the much vaunted France doesn't have 80% nuclear on their grid.
Plus, energy storage production capacity is growing at an exponential rate. It's doubtful that we could grow our nuclear construction crews at that pace.
It's going to be very hard to nuclear to scale as fast as renewables and storage are, if there's even an economic case to be made for nuclear construction, and somebody finally solves the logistic problems of large construction projects in the modern Western world.
We know we can build storage and renewables, but we don't know how to build nuclear anymore, and none, absolutely none, of the nuclear proponents have any proposals to fix it. The best is an entirely new type of small reactor that has been rejects in the past because of its high per unit cost. Perhaps it will work, but who knows? It's a big risk, whereas storage and renewables are a sure bet.
It really isn't. For reference, across Europe we're currently having a meteorological phenomenon with bad weather, clouds, little wind, and low temperatures. It has been ongoing since ~october and is projected to continue into the winter. When Texas was hit with terrible weather last year, it lasted a few days. Multi-day storms, which take out solar and wind, aren't unheard of. 3 hours of storage is OK to even out things, but isn't nowhere near close enough to guarantee reliable electricity.
Personally I think small mass manufacturable fission reactors are the best bet but why are we hung up on either/or? We should aggressively pursue both nuclear and solar/wind generation.
Millions of lives are at stake.
I agree that we should invest in both. But it is not as easy as waving a magic wand. Energy project development is a complicated dance between local power market regulators, local and federal incentives, private investors, and shovel ready/cost-effective technology. And in the rare occasions when congress opens up the wallet, it is a small pie that everyone is fighting over, so the lobbyists start slinging arrows.
The fact is, nuclear can and will be a really great addition to the energy mix. But there are models out there that show that we can build a carbon free grid without it. The big question mark is on the future cost of storage. The consensus is that those costs are going to come down considerably. If so, then going all in on renewables likely gets us to a carbon free grid faster. But this is also a very US centric take. For example China likely has much easier road to rolling out nuclear (less regulatory hurdles, less local interference/input). Where as in the US, I am sure we can build a big national pro-nuclear movement, but the second someone proposes a real life project, the NIMBY's will come out of the woodwork.
This is not the current hurdle when it comes to more nuclear in the US or Europe. Nuclear is very welcome where it is currently under construction, and there's no regulatory reason that these sites have all become construction disasters, it's just bad execution of the reactors.
Even China's attempts to build the French EPR design took twice as long to build as they had estimated initially, and we don't really know how much more in cost.
Nuclear's path to new reactors begins with being able to build on a reliable schedule without exorbitant cost. There are many sites that would welcome more nuclear that would not have NIMBY problems, there's just no one willing to bear all the risk of finding that unicorn contractor that can actually build.
This same problem was also evident during the late 1970s and early 1980s nuclear projects. There was NIMBYism back then affecting projects, but there was also lots of construction malpractice that resulted in big cost overruns. US utilities can not bear the construction risk of a $10B project. Few entities can.
Maybe, maybe not. We know nuclear works so why not also make nuclear in case something happens and we can't build enough storage.
Adjusted for capacity factor this is maybe going to keep up with solar deployment, but definitely not with wind capacity growth in the same country. And China has been the world leader in nuclear deployment for a while now.
Renewables win on a "worse is better" basis - yes, they're intermittent, but they're cheap and deploy in a matter of months without too many specialists involved.
I was suspicious of your numbers so I did a bunch of math and then realized you're using the European comma rather than a decimal. So 12,500 means 12.5, not 12500.
(EIA.gov says the U.S. used about 3.8 trillion kilowatt hours in 2020 [1]. 3.8 trillion kilowatt hours equals 3.8 billion megawatt hours, equals 3.8 million gigawatt hours, equals 3.8 thousand terawatt hours per year or 10.4 twh per day. If we figure the U.S. has about a hundred million households and divide 3,800 twh by that, we get 38 megawatt hours per household per year. This is a very rough estimate, as it doesn't include industrial/commercial/government users. If we divide by 365*24 to cancel out the time units, we get an average consumption of .004338 MW or 4.338 kilowatts per household. That sounds about right.)
Current battery production is only just barely getting started. China dominates production of LFP cells (which are ideal for grid storage) because of patents which are expiring, so hopefully we'll see more production outside of china in the near future.
LFP cells aren't bottlenecked by nickel or cobalt, and so the main resource constraints I believe are lithium, aluminum, and copper which are all quite a bit cheaper and available in bigger quantities. I think prices are expected to eventually settle somewhere around $80 per kwh of capacity for the cells, and I don't think we're that far off that now. (LFP may eventually be displaced by something else, like lithium sulfur or solid state batteries or something, but I think LFP is probably good enough.)
Maybe lithium or copper will become bottlenecks and prices will rise. Let's say prices do hold at about $80 per kwh. Maybe we'll round up to $120 per kwh to account for pack construction, a building to store the batteries, inverters, chargers, and so on. If the average U.S. adult-aged person uses about 2kw on average, then they need 48kwh of storage for 24 hours. That would be about $5760. If we amortize that over ten years, it's about $48 a month. That's kind of expensive, but it's within the realm of what can be done without assuming any major technological breakthroughs. We probably don't need 24 hours of storage, though, if we have enough renewable energy over-production and backup fossil fuel plants to use in extreme situations.

I personally feel that in 10 years in India it will be cheaper to rent an electric car running on LFP for trips < 300 km along with a driver (cheaper here) than buy your own car.
If we imagine a near-future scenario - a battery powered house heated with heat pumps, driving an electric car, during central European foggy winter, which tends to last for about a week at a time. Let's say they use 60kWh/day. We're looking at $100k just for the batteries and installation, even assuming electricity comes free. In ~15-20 years, the batteries reach their recommended cycle life, requiring a choice of another $100k or accepting that what used to be a 3-day storage becomes 2-day
This is not some "extreme situation". It's a completely predictable scenario that recurs with near 100% probability every single year. Then there are places like Ganges river, Bangladesh or Indonesia, home to hundreds of millions of people, where neither solar, nor wind is viable (and land is scarce)
I think it's useful to think in terms of cars. I'm actually doing an EV conversion right now, and I have a motor controller that puts out about 100 kilowatts of 3-phase AC. It came with the motor so I don't have an exact price, but fair market value is probably around $1500. (That's retail cost in quantities of one. Wholesale cost is presumably somewhat less.) It weighs maybe ten pounds or so. That's adequate to power probably about a dozen houses. I don't know if it puts out a sine wave or a square wave. Even if it's the latter, you could imagine a hundred of these things putting out square waves with, say, randomly-varying pulse width and having it average out to a sine wave. There's probably better ways to do that, but anyways the point is that we do have the capacity to switch enormous amounts of power in a very small package for pretty low cost. It's actually kind of amazing.
Maybe if the batteries feed into an HVDC line or they're co-located with a solar plant, then you don't even need to deploy more inverters.
A battery management system for my conversion is a little over a thousand dollars for a setup with about 48 cells. In a big installation you could amortize BMS costs by using bigger cells, or placing them in parallel groups -- the downside being that it might take longer to notice if a cell is going bad. My BMS is made by a company that caters to EV conversions; they're doing low-volume sales. A major utility ordering the equivalent for hundreds of thousands of cells probably can get a nice volume discount.
As far as foggy winters go: renewable energy needs to be traded over a wide geographical area. Purely local generation doesn't really make sense, unless you have some useful purpose for unpredictable amounts of surplus energy. Wind power would need to be a part of it. Even fossil fuels are a reasonable option as long as they're not used very often. Running natural gas plants for a week or two in the dead of winter or in case of grid disruptions seems like a reasonable use of fossil fuels. Indonesia has a lot of land outside of Java. Even Java is pretty sparsely populated outside of cities. Most of it is jungle which we'd like them to keep and farms, but solar doesn't need to take up a huge percentage of available land. Even solar panels on roofs can go a long way.
If they can beat France on cost then here is a political win to be made. Be it using lithium batteries to store up 3-4 weeks worth of the nations energy consumption, or the more likely green hydrogen which is commonly suggested as being more likely choice for wind energy.
The current commercial viable lithium battery solution, that which solar farms has written articles about, is around 4 hours of 80% capacity. Not bad. Every day the batteries get charged when the sun is at its peak and powers prices is at its lowest point, and every day when the sun goes down they can utilize the highest price point as demand exceed supply of cheap energy.
For wind it is a bit more complicated. You can have a few weeks of good weather, followed by a long period of low wind conditions and high demand. A few hours won't cut it, and the more capacity you add the slower the discharge cycle will be. Green hydrogen would be a more economical storage medium, but right now the technology is having a hard time to be economical viable. That said it would benefit the world if Germany made a run for it so we can compare the cost to nuclear.
Unlike pledges, which can be produced instantly, actually bringing reliable power online takes more than 3 years.
It's these types of pledges that make the public view these replacement efforts as fundamentally unserious.
Don't get me wrong, I'm a big fan of nuclear and think the industrialized west should follow in France's footsteps. But we will not get there by 2025. We may never get there as long as we approach this problem in such an unserious manner.
I agree with you however that it will take much longer than 3 years. Lithium batteries can be done today for the kind of storage solution which they are suitable, but not for wind. The green hydrogen might work, but we have yet to see large scale production and we are nowhere near to have it operate as an alternative to natural gas on a nation scale. Germany should really make an attempt if they wish to take a different path from France, but it will likely take a few decades if its successful.
Solar and wind often overproduce (leading to negative prices). This (otherwise useless energy) will be used to produce dihydrogen (water electrolysis), which will be stored, then used to produce electricity (fuel cell).
Salt cavern storage doesn’t change the math.
As for efficiency: https://www.vicat.com/news/vicat-schlumberger-new-energy-cea...

> Salt cavern storage doesn’t change the math
"Total on- and offshore European hydrogen storage potential estimated at 84.8 PWhH2." is pretty significant and pertinent.
Canadian politicians are pledging to develop blue hydrogen in Alberta. That means transforming hydrocarbons into hydrogen.
Yep, it is as stupid as it sounds. Consume fossil fuels to produce hydrogen and label it blue energy.
- able to store otherwise is wasted energy
- affordable (the total price of this storing-then-reconversion into electricity is OK) is adequate
- storing in adequate volumes
is adequate, even if its total efficiency is below .01
Blue hydrogen isn't good (emission-wise), but may be used as a way to evaluate and enhance what will ultimately be a green (electric energy only produced by renewable used to obtain dihydrogen) system.
Moreover there are quick and decisive progress towards better efficiency.
It's as simple as that. They are an exporter.
Look at the chart in your last link:
https://www.nrdc.org/experts/kevin-steinberger/debunking-thr...
They match up demand with load by using a buttload of hydro and and even larger amount of natural gas. We can't use natural gas if we're trying to get rid of fossil fuels and we can't use hydro in places without appropriate geography, so then what?
To say nothing of what happens when solar and wind are "it's cloudy and there's no wind right now" intermittent rather than time-of-day intermittent.

> To start, we’ll consider Sanders’ claim that “scientists tell us” that it’s possible to get to a zero-carbon electrical grid without nuclear power.
> “The shortest answer is yes, that’s true. Scientists do tell us that we can,” said Drew Shindell, a climate scientist at Duke University’s Nicholas School of the Environment.
> Ryan Jones, an expert in electricity systems and a co-founder of Evolved Energy Research, a consulting company that models low-carbon transitions, agreed. “Anyone who says that nuclear is 100% necessary on a technical basis, I would claim, just hasn’t looked at the alternatives in enough detail,” he said in an email.
> Most experts FactCheck.org contacted, including those who think nuclear power should remain an option, said that from a technical perspective, nuclear is not needed to decarbonize the grid.
> Most experts agree that Sanders is correct that it’s technologically possible to decarbonize the grid without using nuclear power. But many researchers also say keeping nuclear on the table makes decarbonization easier and more likely.
> But technically possible is not the same as practically feasible, or the most cost-effective. In that regard, many, although not all, researchers say nuclear — or something like it — is likely to be necessary to some degree. And even if nuclear is ultimately not needed, they say, the safer strategy is not to exclude it.
But what does "technically" mean?
> “All the evidence says it is possible to decarbonize the energy system in the U.S. without using nuclear power,” said Jones. But, he added, there are cases, such as places that don’t have good wind resources, in which building new nuclear plants can reduce the cost of decarbonizing. Depending on the region, he said, “getting to 100% renewable energy is either very expensive or necessitates significant new transmission to import resources from elsewhere.”
> That’s where nuclear can be helpful. It doesn’t have to be nuclear — Jones said carbon capture and sequestration, or CCS, for example, would also work. Sanders’ plan, notably, specifically excludes CCS.
> A large number of scenarios expanded nuclear power, Shindell said, to around double today’s level. He estimated that 90% of the scenarios included nuclear capacity above today’s level, and just one or two scenarios phased out nuclear entirely by 2100.
And the article, that YOU LINKED, goes on like this. I feel like you are being very disingenuous. I don't think anyone (or at least anyone that is informed, but then again that's probably too much to expect here given comments), is saying that nuclear is _absolutely_ necessary. I do think people are saying that it is much easier and cheaper if it is included within the solution. I do think people mischaracterize the arguments though and frame it as "all nuclear" vs "all renewables" but the truth is that both those solutions are absurd. We want a mixture and what that mixture is is going to depend on the region and country that is producing power. It is rather complicated and nuanced and the conversations typically don't acknowledge this.
Maybe part of the problem here is scientific lingo. We say "technically" and "possible" a lot of times, even if our confidence intervals are pretty small. This is something we can work on, but it is often to avoid infighting because someone else will argue "but 'technically' it is possible, just really unlikely/difficult" and you'll have to concede. You'll see this in any "nerd debate".
Either way, I'm going to call you out for misrepresenting your source.

I’m not splitting hairs, I’m arguing very clearly that nuclear won’t get built, it won’t be needed, alternatives will meet demand, and that energy consumption and generation modeling by a variety of energy analysts (across commercial and academic institutions) supports my thesis.
FTFY
But yes, I think you are more accurately capturing my response. And thanks for the defense.
That's his thing. He makes broad to the point of indefensible claims, backs them up with a laundry list of tangentially related links, almost always from the news (and we all know how much the news loves to report "the whole truth"), and then when he gets called out he moves goalposts around muddies the waters and does all sorts of tricks that are SOP when arguing in bad faith. If he were not constantly arguing for viewpoints that more or less correlate with the net average HN user his posts would have been defaulted to dead long ago. I think he believes his own BS so it's debatable whether he is technically arguing in bad faith but it sure fails the duck test.
The only way to win is to not engage.
To be frank, it sounds more like you are disgruntled and are unhappy when the facts presented (as well as the general consensus of the forum, as you mention in the comment I'm replying to) don't align with your belief system. I don't mean to be rude by any means, but I'm unable to come to any other conclusion based on my (imho, polite) interactions with you. I do believe my conclusions based on the data I present. Why would I comment and participate if I didn't? I don't take issue if you choose to not engage, but I'd appreciate if you'd tone down the libel and attacks on my character in a public forum if you choose to not bring facts and argue ideas.
What's the uptime for fission plants? I recall that our "local" nuclear power plant (Trojan https://en.wikipedia.org/wiki/Trojan_Nuclear_Power_Plant ) being down more often than it was up. Maybe it's because it was an old design or something, but it went online in 1975 which doesn't seem that old. It operated from 1975 to 1992.

One may argue that was an overreaction, but the people of Japan beg to differ.
Regardless, those shut down reactors ought to drag down capacity factor for the nuclear industry, if the figures are to be credible.
Wind doesn't always blow and people react badly to melt-down. These are both facts of life.
If we don't have a viable and economically well understood solution for nuclear waste handling , any cost calculations for nuclear is a waste of time .
It's plutonium.
There are treaties that say you can't use spent fuel from civilian power reactors to make nuclear weapons, so nobody admits to doing this, but they probably are. That's where it goes. But since nobody can admit to it, the representative from coal country gets to say 'what about nuclear waste' whenever somebody wants to replace coal with nuclear and nobody can tell them the answer because they're not allowed to admit it. But it's not a bug, it's a feature.
There are also newer reactor designs that can run on plutonium (permanently eliminating it) and also intentionally produce Plutonium-240 in amounts that make it impossible to use for weapons. If that's what we actually wanted to do with it.
We currently do not have a viable economically well understood solution, not hypothetical plans which may work to use plutonium effectively [1] at costs we have no idea about or disposal facility for which costs are not really known yet for all types (HLW/ILW and LLW) waste products we cannot talk costs of ownership.[2]
That doesn't mean we shouldn't do nuclear or not build new plants, but without knowing these costs any estimate of cost of ownership is useless numbers in the air as nobody knows what it is going to actually cost yet.
[1] Again engineering and economics, engineering maybe well understood, costs are not, we don't know the costs until we build a few, nuclear is notorious for widely over running cost estimates compared to any other power generation method.
[2] We don't need to measure thousand years of disposal to know the costs, we just need to run an actual disposal site for few years to really estimate the costs .
There's plenty of chemical waste from fossil fuel use and petrochemicals that may be very long lived and cause actual health impacts if inadequately stored, too... with basically no efforts made to apply the same sorts of criteria of quality and longevity of disposal of waste.
So effectively, we compare the (not fully known) costs of really mitigating the long term impacts of nuclear with outstanding storage ... to doing nothing about greater impacts from fossil fuels (both short term impacts and long-lived waste).
A enforced storage/cleanup would be ideal yes, U.S. has never agreed to any standards, even know while Kerry talking about shutting down Coal by 2030 from nowhere, the U.S. government explicitly did not join the pledge to shutdown coal in 2030s like some countries did last week in COP26, and has always refused to get into any international binding agreement.
From a economic perspective what you are mandated to pay for [1] today is how you model costs of the project. Running a nuclear plant today means you have to keep spent in fuel on premise with no horizon for that status quo to change. Economic model for actual money going to be spent now ( not environmental or social costs models of indirect costs) has to factor that in the cost of ownership of a plant.
Is that unfair because fossil fuels has indirect costs ? yes it is, but that does not matter from an economic decision making point of view when financing a new power plant today. Carbon tax is not a solution either as currently being envisioned [1]
---
[1] The carbon tax that is being discussed in the U.S. would be a disaster .
a) The tax rate is quite low which will supposedly increase over the years. The political pendulum in the U.S. almost guarantees that when republicans come to power in 2024 or later they are going repeal/relax a carbon tax like with Paris Agreement. U.S. is not currently in position to make serious long term commitments on any policy.
b) The polluters want limits *relaxed* as part of the tax deal. That means they want to be able to pollute as much as they want and just pay a small tax to do so ,which is why it is actually supported by some republicans I suppose.
c) Finally there is no plans on how to use the money to *remove* CO2 from the atmosphere, reducing emissions with that money with green investments is not good enough as polluters are in theory paying the government to take care of the problem and will pollute as they wish so government needs to clean the CO2 up. CCS is not viable economically today certainly not at the tax rate being proposed.My comment isn't talking about CO2. I'm talking about e.g. benzene.
Nuclear waste disposal is concerned/stymied by the possibility that the water table in remote areas where no one lives currently may be moderately contaminated in thousands of years if it fails, and this contamination may last thousands of years.
Whereas we have contaminated the water table in populated areas with benzene and aromatics -- where they will remain contaminated for thousands of tens of thousands of years.
That is, we're trying to prevent theoretical harms in the distant future, and in so doing, we're accepting much larger present harms.
If there are no other(clean) options having equivalent characteristics (consistent base load, scalability, location etc) to augment solar/wind etc ( whose costs are very well understood now including end of life costs) , then we are not choosing because it is cheaper, we are doing it because there is no choice.
[1] All plants will have some cost deviations, but nuclear has much higher both time and cost deviation from plan estimates.
See this graph for the spread based on Z number (Protons + Neutrons).

Parker Solar probe launched in 2018 will take 7 years and multiple gravity assits to slow down enough to get close orbit to the sun.
It is also why BepiColombo will take 6-7 years to reach mercury orbit with similar steep delta-v costs.
Here is a delta V map [1] for the solar system. It would be easier to launch our trash to escape the solar system rather than land it in the sun.
Either way we generate nuclear waste in the millions of pounds per year , launch costs with everything spaceX is doing is nowhere cheap enough to even get the waste in significant quantities to even LEO.
[1]https://upload.wikimedia.org/wikipedia/commons/9/93/Solar_sy...
I don't have the exact numbers but roughly 9.08 μN/m2 is the radiation pressure @ 1 AU and depending on sail configuration (Square/Lattice etc) we can expect a λ ~ 0.25 , with a 800m2 and 5g/m2 density sail we can get effective acceleration around 1 mm/sec2, so you can reach near the sun in few(<10) years ignoring efficiency losses due to quartering and any payload weight etc.
In a real system you could speed this up a bit by using powerful lasers to improve acceleration and orbital methods like a cycler, but meaningful payload size would make it slower too.
The basic metric is that escape velocity of solar system is 30km/s earth starts you at 18km/s : it is easier to add 12 than drop by 18. You can do the same things at 2/3 delta-v budget and push your payload out of the solar system than into the sun.
[1] All orbits decay and eventually(10^150+ years) even the Earth will fall into sun ( or equivalent mass white drawf) so yes it is always possible
Between dying in next 100-200 years because of climate change or risking nuclear contamination problems 100's of years in the future in concentrated locations the later is always preferable yes.
I am not saying there is no good reason to move to nuclear, but cost is not one of them, as literally we don't know what it will cost yet.
> Since breeder reactors on a closed fuel cycle would use nearly all of the actinides fed into them as fuel, [the] volume of waste they generate would be reduced by a factor of about 100
> In addition, the waste from a breeder reactor has a different decay behavior, because it is made up of different materials. [Its] fission products have a peculiar 'gap' in their aggregate half-lives, such that no fission products have a half-life between 91 years and two hundred thousand years. As a result of this physical oddity, after several hundred years in storage, the activity of the radioactive waste from a Fast Breeder Reactor would quickly drop to the low level of the long-lived fission products.
> ". In 2010 the International Panel on Fissile Materials said "After six decades and the expenditure of the equivalent of tens of billions of dollars, the promise of breeder reactors remains largely unfulfilled and efforts to commercialize them have been steadily cut back in most countries"."
I have been following FBR progress especially thorium based ones, as it was considered to be India's path to energy independence since the 1950's. The progress has been slow and expensive and still a lot of research is left to do, so to say meaningfully that waste will reduce is not a viable plan today or next 20 years.
One plant should not be judged on its intermittency alone. Its just not how the system works at a connected-grid scale.
Likewise we could make power stations that could withstand hurricanes, or earthquakes, or tsunamis, and so on. We don't usually though, it's too expensive (not to defend the decision not to weather proof more in this case, it wasn't really that far outside of the expected operating conditions as I understand the situation).
I’m not an energy grid expert but I guess it’s hard to have nuclear, gas wind and solar playing together because if it weren’t, people would just get on with it?
So we can store our storage centers closer to population centers, but we can't generate it close by. We now have lots of transmission losses and opportunities for failures.
The problem with all this is that it is exceedingly complicated and most people are trying to simplify the problem. But here even including second order factors doesn't give you good approximations of the solution.
While costs of transmission infrastructure required for country scale (larger distances for lower correlation) energy dispatch are recognized, its more abstract challenges are less well acknowledged. Dispatch at this level is not just about developments in grid integration or hardware like solid state "transformers", it also has a complex routing coordination aspect requiring research in control and even game theory [1].
A lack in wind and solar can sometimes occur simultaneously. Analysis of German wind turbines data observed that experiencing a stretch of almost a week with generation as low as 10% installed capacity was likely within a given year [2]. Surprising/extreme weather events like Europe's recent "wind drought" are rare but there remains a large amount of uncertainty in how changes in climate will affect the tail of this distribution. Tools such as coordinating distributed generation and improvements in storage tech will surely help smooth generation, nuclear is another powerful tool in that toolbox.

The problem is that Nuclear may not be economical if it is only used when both solar and wind run out. Nuclear has large fixed costs. And almost zero marginal costs. So the average costs -- what needs to be charged in order to avoid bankruptcy, increase as you use it less.
That means every solar panel you add makes the nuclear power a bit more expensive. And that incentivizes adding more solar. Up until you drive the nuclear out of business, and then suddenly you don't have reliable power anymore.
Then you are faced with a situation of
a) only having nuclear power which can provide for all of your needs, in which case adding solar is an unnecessary expense
b) only having solar+wind and an unreliable grid, which means you need to add batteries to cover solar+wind. And the price of those batteries may be more than the price of the nuclear plant.
c) having nuclear and solar both, with enough subsidies given to the nuclear plant to keep it in business so that the total solution is more costly than just going with nuclear.
So yeah, there really is a tension between nuclear and solar.
This is not the situation, however, with solar and coal. Because coal plants are damn cheap, and they have higher marginal costs. Thus solar can coexist with coal or with gas much better than with nuclear.
Therefore the economics is such that as people promote solar the result is a decrease in nuclear and an increase in coal and gas.
Current electricity demand is heavily biased to daytime use even with cheap nighttime prices causing people to shift demand to use that. Start to ramp up solar to the point where daytime demand is higher and a great deal of nighttime demand drops off.
Grid storage isn’t cheap enough to store energy at current nighttime rates, but it’s cheap enough to have a balanced grid backed by hydro, wind, and solar even with zero fossil fuels. The tipping point to cheap daytime rates and expensive nighttime rates isn’t inherently better or worse, it just reflecting the future economic reality.
You are correct that my model is simplified. I ignore the issue that demand isn't really stable, and you need some peaker plants.
The problem is that Solar isn't really a good solution for peaker plants, because those need to be reliable. So I don't think this simplification undermines the tradeoffs I was describing, although I agree that in the space of peaker plants, there can be some combination of solar and gas to handle peaks when it is sunny and also when it is not sunny. Just be prepared that you need enough gas and coal to cover all the generating capacity you are getting from solar and wind, which is again very expensive.
> grid backed by hydro, wind, and solar even with zero fossil fuels
This requires a lot of hydro, more than most nations have together with really punitive electric rates when there is an absence of wind or solar. I mean, massively punitive rates, because demand for electricity is highly price inelastic. So be prepared for rates to go up 10x or 20x or even 100x when there is a stretch of windless days with weak sun. I think there is a reason why no nation has gone this route except oddballs like Iceland with their reliable geothermal.
At that point you are still going to get multiple day stretches where wind and solar only cover ~1/2 of daily demand but hydro can make up the difference on such occasions even if it’s only supplying 6.6% of annual US demand. Basically you get 1-2% hydro on most days and on 5% of days you a lot of energy stored.
As to high costs, because of the excess solar you’re generally filling batteries with nearly free electricity. Average nighttime wholesale prices therefore end up at ~10c/kWh or whatever the battery storage costs settle on, but daytime rates when most demand actually takes place are going to tank. That’s a net reduction in average prices. Trying to make a grid from Nuclear + batteries on the other hand means your paying Nuclear prices at night, but nuclear + battery prices in the daytime which is the opposite of what you want. Nuclear + fossil fuels on the other hand simply doesn’t go far enough.
Now in a mostly solar world a very low percentage of electricity may end up generated by fossil fuels, but a 99.X% solution is success by any reasonable metric.
PS: As a sanity check you can look at what people are paying when their off grid and then realize that’s very much a worst case.
Also, be careful when looking at wind and solar minimal percentages. It’s the difference between median output and minimum output that matters not maximum output. Long term it’s likely something like 30 to 50% of all solar generation is going to be wasted simply because it’s just that cheap.
In terms of fish, large dams are needed for flood control and water. But rivers and streams often have huge numbers of small dams that are equally problematic and far less useful.
The EU would need about 10k Cerro Dominador's (which would cover about 1% of the surface area of the EU) to supply its energy needs at worst case (using ~1kwh/m2/day seen during dec/jan).
Cryogenic energy storage ("liquid air") plants have been deployed - a 15 MWh (5 MW peak) grid-scale demonstration plant has been operating in Greater Manchester near where I live since 2018, and there's a permanent 250 MWh (50 MW peak) plant under construction on the opposite side of the city region.
Granted that peak energy usage in the UK today was around 42 GW, so it's a small fraction (OTOO a tenth of a percent at peak) of what's needed, but... it's coming.
I fully agree with you, though, that nuclear is needed. Renewables + storage can't be the complete answer. I'm a wind, solar and nuclear advocate.
The next level is using residential HVAC systems the same way. Comfortable temperatures are a range, so heating/cooling can push the temps to one end of the range, and when there is less electricity available, they can drift to the other end.
The charger for your electric car is another very practical sink for cheap electricity.
This is accomplished by having a spot price for electricity, and then people buying thermostats that query the spot price and turn HVAC, hot water heater, car battery chargers, etc., on and off.
This can be extended EVEN FURTHER by heating/cooling a pile of rocks to later use to heat/cool the house.
A battery consisting of a pile of rocks can't be expensive.
The idea is to not only adjust supply to the demand, but to shape the demand to the supply.
I am utterly astonished that this is never, ever discussed when talking about solutions to fluctuating supply. Having fixed electricity rates 24/7 is simply madness in today's electricity generation situation.
Besides, if you could buy an electric water heater that runs when electricity is mostly free, wouldn't you replace your gas heater? I would.
You're taking some level of risk regardless of which choice you make or the government makes for you.
It's more strict for oil based heating. Even replacing an existing system is not allowed anymore from 2022.
Is building nuclear power faster than building Lithium Battery Factories?
Nuclear power is still kind of fossil fuels though, so it’s just kicking the can down the road… but it’s a big kick.
Geographically independent power, no carbon emissions, and no intermittency. It fulfills anything we'd get from fusion, except we have 70 years of experience using it in our power grids.
The problem is humanity needs to get it's act together and stop allowing politics, NIMBY and a severe lack of understanding of science from getting in the way of saving itself.
Nuclear proliferation is the least of our problems if we can't grow our food outside anymore and half our cities are underwater.
Nothing will work in 100% of the world.
The point is, do it where it does make sense.
This is completely backwards. Demand is highly price inelastic and inversely correlated with the supply of renewables. People usually eat at night. They heat their homes overnight. None of these things will change based on energy prices.
What you're proposing is a tax on the poor, and no practical benefit to boot.
> The charger for your electric car is another very practical sink for cheap electricity.
I don't have an electric car. I do not know anybody with an electric car. And wouldn't the surplus show up specifically when those cars aren't at the home?
> A battery consisting of a pile of rocks can't be expensive.
No, but the labor cost of hooking up your pile of rocks battery will be impractical for almost everyone.
> The next level is using residential HVAC systems the same way.
Again, I don't know anybody with an HVAC system. Everything here in the UK is based on natural gas and would cost an unbelievable amount of money to replace with electric.
He basically shared that some costly energy consumption (such as water heating) can be easily shaped to the supply.
Total costs will be low if you can also find a perfectly spherical plumber (& electrician (& WiFi/4G-technician)) that charges less than $1 per hour for installation.
Obviously, nobody buys them.
Perhaps the laws and insurance rules are less strict where you are?
I also think that very few people feel comfortable working on household wiring, and very few people are comfortable with fixing plumbed in appliances.
I will add that the law is good, because houses get sold, and wiring is invisible, and no future owner wants to find out their wiring is bodged up by some clueless software engineer.
There is some truely terrifyingly dangerous wiring done by amateurs.
If we're dealing with rural areas reliable internet isn't always a given. The UK had an interesting solution for this for older electricity meters which encodes data in the BBC Radio 4 LW (198 kHz AM) radio station. Most of the country is covered by a single transmitter because of how efficiently LF waves propagate and it doesn't require an internet connection to work. Sadly I think the rise of smart meters will probably be the death knell for Radio 4 LW too.
I think it's easy to forget how flakey the internet can be outside of major cities in some places. Having lived in places that are fairly off the beaten track I wouldn't want my electricity bill to depend on always having a reliable WiFi connection for example.
Yes, since my proposed solution is not 100% it's useless.
Will have them subsidized in units they own (not that poor people generally own) and mandated in units they rent
There's no evidence of that. The only evidence is that when the price is exactly the same 24/7, no elasticity is observed.
> and would cost an unbelievable amount of money to replace with electric
I've had to replace gas furnaces and gas water heaters now and then. They don't last more than 10 years or so.
BTW, everybody in Arizona has A/C. Amazingly, A/C demand peaks when the sun is high in the sky.
> I do not know anybody with an electric car
You will.
Here in California, peak AC demand is late afternoon. Environmental thermal mass means peak outdoor temperature happens a fair bit after peak insolation. Structures take even more time to heat up and add additional delay. Finally, people arriving home from work means increased AC use, too.
Demand stays fairly high after it gets dark.
(And it's my understanding most other places keep daytime heat later than here).
This particular one is only mildly effective; precooling can lower later demand somewhat.
My house is very well insulated, but I still cannot coast from 5:30pm to 9:30pm (when windows are sufficient for comfort and demand really starts to slope off) without an excessive amount of prechilling. My structure, insulation, and attic are all preheated by the day's heat and so there is a big warm thermal mass next to my living space.
Also, opening windows overnight increases indoor humidity, which in turn requires more air conditioning the next day.
If it'll save you 10% on your electric bill, would you do it? I would. And reducing peak demand by 10% can really reduce the cost and need for grid battery storage.
Best of all, doing this sort of management of your HVAC system costs you essentially nothing. It's picking money off the ground.
It is not useless but it does have its price in terms of complexity and usability. With off peak at night you tend to run out of hot water during the day at times e.g. if you have visitors.
It is not a new idea and it is no panacea.
I've never seen it mentioned in any articles about baseline and peak power needs, and all that talk about grid batteries.
> and it is no panacea.
Nobody said it was. If it would, say, reduce the need for grid batteries by 10%, that would be an enormous savings. All by changing a new thermostat.
I remember in the 70s energy crisis the appearance of programmable thermostats what would automatically lower the temp at night. My proposal just extends that.
Magically when solar production is at it's peak!
The first is dubious, the second is... highly location dependent.
Peak demand in California matches peak solar output pretty well; before solar was big, supply concerns focused on peak demand hours, in the afternoon; now they are in the evening because solar has made the highest gross demand time the time where there is the least concern for supply.
> No, but the labor cost of hooking up your pile of rocks battery will be impractical for almost everyone.
The labor cost of hooking it up isn't that bad, geothermal heat pumps aren't that costly.
Insulating the pile of rocks battery is probably the hard part.
And electric cars actually tend to get charged at night, while people sleep, when solar isn't generating.
Because there's no incentive to do otherwise. Of course people don't time shift their electric use when there's no incentive to.
If every parking space had a 7 kW connection (230 V, 30 A single phase) almost all cars could be fully charged while their owners were at work. In fact even an ordinary 3 kW connection would be enough for most people; even my 2015 Tesla Model S adds more than 12 km per hour at 3 kW.
If car owners aren't paying for the power, then who is?
And either way, what does it cost to wire up all the parking spaces?
Paid parking lots solved that problem eons ago.
> what does it cost to wire up all the parking spaces?
I wonder how people ever managed to electrify street lamps, any exterior powered things, even the per-stall electric parking meters I've encountered.
All I'm saying is, the costs of these sorts of demand management measures for renewables should not be overlooked in comparisons with the cost of nuclear, which doesn't need them.
True, you'll need a heavier wire. And the cost of installing wire far exceeds the cost of the wire. When my house was wired up, the cost of the installation was 40 times the cost of the reels of wire.
People talk about "demand management" as if it's free. Not much power available, just shut down some factories. But if you're running your factories only half the time, you need to build twice as many factories to make the same stuff. You're making renewables look artificially cheap by externalizing costs to their customers.
Instead, "you can charge it while you work". Not many people drive more than an hour a day - that's 23 hours where it sits. I see lots of cars parked in residential streets during the day. Paid parking lots catering to commuters can also offer charging services.
> just shut down some factories
That's your strawman. I didn't propose that.
Same principle applies to most things. If electricity stops being readily available all the time, then you're introducing a new constraint that people have to optimize for. If that means they change their behavior, then they're doing something more expensive than whatever they were doing before, when they optimized without that constraint.
That extra cost generally isn't figured into the optimistic estimates of how cheap renewables are, but it's still a cost that society pays.
Building lots of charging stations at employer parking lots is also a new cost, that doesn't get counted against renewables.
> Building lots of charging stations at employer parking lots is also a new cost, that doesn't get counted against renewables.
The cost needs to be compared with building grid storage batteries.
Many factories don't run 24/7. And yet more factories don't run their most energy intensive processes continuously even when they factory is "running".
Most homes don't have enough free space for a big pile of rocks to increase thermal mass. My home has pretty good insulation but on hot days we're going to be miserable without AC in the evening regardless of how much we chilled the house down earlier.
Again, we're just talking the thermostat for it.
> I don't think there are even any widely available on the market today which will automatically increase the temperature at mid day in anticipation of an electricity shortage later.
Why should there be? Electric rates are fixed 24/7. All the power company has to do is provide an API to get the spot price, and start varying the electric rates according to supply. The market will adapt.
> Most homes don't have enough free space for a big pile of rocks to increase thermal mass.
Criminy. Do I have to design it, too? Most homes have a basement or a crawl space.
They aren’t for some people in some countries.
Not sure if this is true or not in total, but in the Southern US, the vast majority of houses have neither.
Attics are another place to put it.
Since 2000 most homes have been slab construction 60/40 by 2013 78/32.
It is cheaper and quicker to build slab and the way the housing market works means that developers choose what to build.
In Arizona, everything was slab-on-grade because the ground was very, very dry. That's not so in most other areas.
The crawl space keeps the wood off the ground where it wicks up moisture and quickly rots. Cement wicks up moisture, too. Try a slab in Seattle, for instance, and your house will soon be uninhabitable from mildew.
> 30 percent of new single-family homes started in 2013 have a full or partial basement, 54 percent are built on slabs, and 15 percent have a crawl space.

I think you are looking at a small subset of data.
I can't imagine anyone wanting to start a business strictly based around a last-mile solution, when other solutions already exist and are substantially more efficient and scalable.
You're also assuming that the regulatory bodies for each municipality inherently want things to be efficient and customer-friendly, but that's just not how it works. In the US alone, all you need is to look at the disaster in Texas this past winter, where prices jumped to 180x their usual rates -- and for brazenly nefarious reasons.
Want me to show you my electric bill? Fixed rate, 24/7, in every place I've lived, for my entire long life. California, land of the rolling blackouts because they can't match demand with supply, also has fixed electric rates.
> is a solution that works for some homes, in some municipalities, under very specific circumstances.
Oh come on.
> I can't imagine anyone wanting to start a business strictly based around a last-mile solution, when other solutions already exist and are substantially more efficient and scalable.
Look at the endless variety of thermostat innovation for your HVAC system. Even internet connected ones. Why would you suggest that simply automatically adjusting the thermostat based on spot prices for electricity is inefficient and unscalable?
> You're also assuming that the regulatory bodies for each municipality inherently want things to be efficient and customer-friendly
I infer no such thing. I suggested making changes.
> where prices jumped to 180x their usual rates
And I bet none of those customers had thermostats connected to the spot price of the electricity.
Do you know that the pump price of gas varies every day? That's demand shaping. And it works.
If you really think your ideas are unique and revolutionary and "correct," then I recommend going down to your local utility and pitching them heated rocks, instead of trying to convince the internet that you're right about everything -- see how long it takes for them to stop laughing.
As an aside, my father invented, developed and sold a heated rocks system over 40 years ago. It definitely worked, but the concept itself proved to be too inefficient, impractical and non-scalable, and because of that it never got adopted beyond a few off-the-grid folks. So, when I say that your ideas would only work in very specific circumstances, that's based on actual historical information, not some imagined universe where the entire world is exactly the same as you, personally, have experienced.
So, the 5 states and 2 foreign countries I've lived in are a self-centered bubble? I'll turn that around. Where in the US are variable, minute by minute electricity pricing which can be remotely queried?
> see how long it takes for them to stop laughing
First they ignore you, then they laugh, then they race to implement it. What I see in this thread is "electricity rates are fixed 24/7, that's the way they've always been, anything else is inconceivable".
Frankly, why should the utility care? They'd probably profit quite a bit from massive government money to develop grid storage batteries.
It is typical for solar heated homes to use rocks/concrete for heat storage. Traditional adobe homes with thick earthen walls also are very, very good at being a heat sink and source, making the home comfortable. As mentioned elsewhere, I have a Swedish masonry fireplace which uses masonry to store the heat and slowly release it. It's a simple heated rock system. The Swedes have used that design for centuries.
As for your father's invention, I have no idea what went wrong with it. Perhaps a couple manufacturing engineers having a look could improve it quite a bit. After all, rarely does the first iteration of a concept be very practical.
As for my father's invention, the reason it didn't catch on was for the same reason that piles of rocks don't actually scale -- it's incredibly inefficient, as is every other rock-based thermal storage. Just because it's a functional method of accomplishing a task, doesn't mean it's the best method, and what you've repeatedly asserted is that YOUR idea should be the best method simply because you say so.
Explain.
> what a utility SHOULD care about as opposed to what they ACTUALLY do.
Obviously, as the grid supply dynamics change, what they traditionally did no longer works.

Most people on this planet don't live in HVACed single family houses. That's what the grandparent meant by your "bubble".
That still leaves billions of people. What's your solution? Rolling blackouts?
> those places
Many multi-unit buildings have central heating. Which means central thermal mass "batteries" are more cost-effective on a per-unit basis.
And 100% of that energy gets recovered as it slowly returns to ambient temperature.
You're confusing heat with temperature.
> you are making up science in your head that does not actually exist
You should be careful about making such statements. You're quite wrong. The heat going into the rock will be 100% returned. All of it. Where do you imagine it will go?
I'm done trying to explain 6th grade Earth science to you. You're either trolling or extremely unwilling to accept reality, so unless you have actual evidence for any of your claims, please stop pretending that you're some super genius who knows better than every scientist and engineer on the planet.
The energy comes back out of the rocks in the form of heat. 100% of it. No losses. Energy in equals energy out. If you heat the rock by 1 degree, in cooling off 1 degree it will release 100% of the heat absorbed.
> you're some super genius who knows better than every scientist and engineer on the planet
I suggest you ask an actual thermodynamicist, not a 6th grader. I don't need to present evidence that conservation of energy applies. After all, it's the law.
As I've explained multiple times now, it's a matter of where the heat originally came from, and it requires 3-5x MORE ENERGY to impart the THE SAME AMOUNT OF HEAT to a rock as it does water. That's the entire point, and is the portion of thermodynamics that you keep pretending doesn't exist. I'm not sure how many more times or ways I can explain this to you, because you clearly don't want to accept that the original heat input doesn't magically manifest itself.
I've provided you with evidence for all of this, but you're still making the same baseless argument. Your ignorance of the subject is exhausting to engage with, so if that was your intent, I guess you win today's Troll Award. But you're still completely wrong about the science, you're unwilling to provide any evidence to back up your claims (because the evidence doesn't exist), you have no basis for your argument at all, and you should be ashamed of yourself for insisting otherwise in such an aggressively arrogant manner.
Yet you said it was only 20% efficient. Where did the 80% of the energy go?
> it requires 3-5x MORE ENERGY to impart the THE SAME AMOUNT OF HEAT to a rock as it does water
No, it doesn't. It's the same. Unless you've confused heat with temperature. Or you didn't try to heat the rock in an enclosed, insulated box, and the rocks were radiating the heat away almost as fast as it was applied.
"Heat is a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy."
https://www.physicsclassroom.com/Class/thermalP/u18l1d.cfm
QED.
> No, it doesn't. It's the same.
This statement is the entire premise of your argument, but is directly refuted by the source you provided, and is so ridiculously absurd that I can't take you seriously anymore. You have to be trolling.
Then it should be no trouble for you to present a literal quote of what I said and a literal quote that says the opposite.
Your gaslighting continues, and I'm beyond tired of it.
If you need evidence of that, feel free to read any of the provided materials, especially the concrete heat storage systems that have already been built which, unsurprisingly, use 2x as much electricity to store 50% as much heat.
So, unless you have actual information to provide, you saying I'm wrong doesn't add anything to the conversation.
What does it matter that Y kg of rocks stores that energy at a lower temperature than Y kg of water? Or, conversely, that if you insist on having your energy-storage temperature set at some specific Z' degrees, you can store that amount of heat energy in much fewer kg of rocks than of water?
You're mixing up temperature and energy. They're not the same thing.
It also means more thermal losses and huge thermal masses required to make any difference.
In Europe at least, the vast majority of people live in high-rise blocks, which barely have adequate parking space, never mind any room for electricity storage. None of your solutions are even close to practical from this point of view alone.
Not to mention, relying on the market to be rational really can't be the solution to keeping the grid functional. Blackouts are massively disruptive and potentially life threatening.
If you have a hot water heater, you already have a heat storage device that can be used to shift demand.
That’s a matter of forced mixing. The temp coming out of the hot water heater itself should have very little to do with the faucet temp in 2021. (Yes I realize it still does)
Linky is an electric meter connected to the grid through PLC but it embeds the required hardware to eventually drive appliances consumption.
It provides a dry contact which can be open or closed remotely via the grid’s PLC. So it can be open or closed even without internet.
You can imagine to use this contact to drive a power line dedicated to your water boiler, electric car …
IIRC, atm, the only provided possibility is to open/close the contact via a web API / a smartphone app. But in the future, it may become controllable by the electricity provider to be automatically opened / closed based on the grid’s state (and the electricity price)

And before anyone replies that it won't come that far, please consider three things:
- We are using an AC power network, not a DC one.
- The power grid is the backbone of modern society.
- Try to find one big technology deployment which was deemed "safe" and actually kept that promise. Because I can easily find countless counter examples reaching from the Titanic to your latest game console.
So the surface attack of this feature is that an hacker could stop you water boiler to heat or your car to charge, but you'd just have to plug them to the rest of your (still working) network.
And yes, the electricity provider could probably switch off your provisioning remotely. But that's not a novelty. That was always possible. Now it can be done safely.
And I'd like to add that the Linky is NOT connected to the internet. It's connected to the electricity provider network so you need to control the electricity provider in order to hack the meter. But at this point, if you gain control of the network, there is no interest in hacking the meters.
A binary solution is far less efficient than one where the consumer decides if he's willing to pay the spot price or not. Especially if that is controlled from afar.
Shaping demand with prices is how free markets work. Shaping demand via some remote bureaucrat's decision to randomly cut people off is socialism.
I call something socialist when government regulators set the price, or otherwise interfere with the price.

Our house built 7 years ago has an Enefarm fuel cell/hot water heater. Every house in our neighborhood and every house I’ve seen by the same builder has one. It approaches things a little bit differently but to the same effect. It learns your energy use patterns and turns on the fuel cell (using LP gas) when you usually use electricity, generating hot water as a side effect. The future is already here, it’s just not evenly distributed yet.

> it's a safety hazard in homes with small children; hot water temperature should never be hot enough to cause burns when someone turns on the faucet.
Internally it stores water at 65 degrees C but mixes it with cold water to to supply all water to the house at a certain temp. We have ours set to 40C but you can change it on a control panel. Of course, there are mixing taps at the sinks/showers. It’s very common for shower temp controls here to have a extra stop at 40C that requires pressing a button to exceed.
> Most homes don't have enough free space for a big pile of rocks to increase thermal mass
I don’t know about cooling but the ones that take advantage of cheap electricity at night to store up heat and release slowly over the day are not massive.

Even if it is only 10%, that's 10% less grid storage batteries needed.
Ya know, car engine efficiency has improved dramatically over the last 50 years. Each specific improvement was small - but the aggregate adds up.

As the poster above you pointed out the capacity of LI batteries is tiny. Yet you tout car batteries as though that were a new idea and a meaningful solution. And you ignore the fact that if you use car batteries as storage for the grid, that detracts from their use to, you know, run cars.
You also ignore the losses from your solutions. What is the round trip loss from heating up rocks and getting the energy back? It is huge. And you artfully forgot to mention all the equipment needed to get the energy back out in usable form such as electricity.
All the books and studies talk about load shaping, contrary to your "astonishment" that no-one is considering this "brilliant idea". The problems with load shaping are many. If you shut a factory down to spare the grid, then it is not producing. So all else being equal, you need more factories for the same production. Building and maintaining those extra factories takes labor, management, and energy.
Getting people to turn off air conditioning means that they are less comfortable, or perhaps unable to sleep, or unable to work. The South of the US more or less became viable economically due to air conditioning.
This is not unique to you, but I am really fed up with people spouting half-assed ideas and thinking that they constitute a solution.
As they said in the dot.com era - ideas are cheap.
That said, the parent comment's ideas are bad and ignorant, for the reasons you mentioned and more.
The parents comments are neither bad nor ignorant. They can be summarized as demand management.
Utilities hate demand management. If they run an efficient market with incentives to shift demand, profits drop. Their profits are based on cost, increasing costs is how they improve their margins. Same as healthcare, band-aids cost $1400 at a hospital. When profits are capped by regulation, this is the workaround.
Don't get suckered into fossil fuel narrative. All the narrative against any kind of progress comes from industry that benefits from status quo and regurgitated by media.
You also just bolstered my point about the OC's ideas being bad, because you admitted that the utility providers aren't motivated to do such a thing, which was the entire foundation of his argument -- that some imaginarily ethical regulatory organization is going to force utilities to be equally ethical, efficient and technologically progressive.
And just to be perfectly clear, using a pile of heated rocks as primary energy storage is beyond ridiculous and entirely ignorant of thermodynamics and physics in general.
So, yes, the ideas were both bad and ignorant.
edit to add more specific link: https://en.wikipedia.org/wiki/Storage_heater
Also, you just made the exact opposite point of the OC in regards to rates, and then provided a link about thermal energy storage that proves the only point I made, which is its inefficiency[1] at small scale -- and at large scale it is not a pile of rocks inside every home.
[1] https://en.wikipedia.org/wiki/Thermal_energy_storage#Heat_st...
Except there are many examples of such in common use. For example, passive solar houses use this technique.
> some imaginarily ethical regulatory organization is going to force utilities to be equally ethical, efficient and technologically progressive.
Current(1) regulatory organizations fix electricity rates. Electric utilities are already heavily regulated.
And again, you're making a sweeping generalization about regulatory organizations that isn't even remotely true, and you have nothing to base it on. In the US alone, the majority of states have systems that combine both regulated and unregulated rates, and even in the states where the regulators decide on the rate, a utility can request rate increases at any time.
Your entire premise is based around some mystical altruism that doesn't actually exist in government or business.

Please elaborate how heating a rock, putting it in an insulated box, and taking it out of that box later to release it's heat to the air is "incredibly inefficient" compared to heating the air directly.

You're going to be tempted to reference the last link as evidence in your favor, but it's very much the opposite. It's saying the advantage concrete has is its ability to be heated to higher temperatures than water. Except it doesn't get to break the laws of physics and still requires 3-5x as much energy input, which is why it's really only practical for large scale operations that can safely heat the concrete to extreme temperatures, using massive amounts of electricity that would otherwise be wasted due to low grid demand. They are still losing at least 75% efficiency in that process, but it's slightly better than losing 100%, as long as you pretend there aren't any environmental impacts of producing all that extra concrete.
You'll notice the first installation referenced in this section actually uses 1,000 cubic feet of additional reinforced concrete and an entire home's worth of additional electricity to supply a single home with 50% of its heating and hot water. That's a second foundation's worth of concrete, for perspective.
And moreover, as we've already established, this concept isn't new at all. If it were legitimately more efficient and more practical than alternatives, every home would already be using its foundation as heat storage. But they don't, because it's not.
I suggest you read up on laws of conservation. If you want to be less than 100% efficient, you have to lose energy somehow, somewhere.
I don't know where you're getting efficiency numbers from, but quoting from your reference, storage in Sorø will double as electricity storage while beating your numbers on electricity alone.
"A similar system is scheduled for Sorø, Denmark, with 41–58% of the stored 18 MWh heat returned for the town's district heating, and 30–41% returned as electricity."
BTW, when you switch rocks for concrete, of course it's expensive and makes no sense - people don't add tons of concrete for thermal storage. Though they do use it, if it's there, and add rocks, brick walls, water tanks, phase change materials etc, if they want more.
I don't think that's the right way to phrase it. The South was clearly economically viable before A/C. It's kinda like saying that New York City wasn't economically viable until the invention of the safety elevator.
Overall I agree with your views on "half-assed ideas". I want to elaborate on this one topic a bit more, because it presses a button of mine.
On thing A/C did was make it possible to build cheap homes following northern tastes and styles, on the assumption power would remain cheap. Northerners could move in without having to adapt their customs and practices much.
Southern vernacular architecture includes high ceilings (so the heat rises above the people), lots of windows (to let the air go through and heat escape), and with the house raised off the ground (so cooling air flows underneath). This describes the A/C-less Florida house I grew up in. An even more traditional design would have a wraparound porch, to provide extra shade and let the windows stay open even when it rains.
OTOH, A/C encouraged house designs which require A/C to be comfortable - a sort of co-dependency. These vernacular features make the A/C bill higher, so they weren't included in newer homes. I tried living in a Florida home designed for A/C, but without using the A/C. Not only was it much less comfortable, as you write, but we started getting mold because of the humidity. A house made for A/C doesn't have much air flow.
So I don't think the argument is simply 'getting people to turn off air conditioning', but 'getting people to design houses which are a better fit for the local climate and have better long-term sustainability.'
That's of course hard, and expensive.
It's also hard to change lifestyles to fit the climate. Eg, the dominant US culture doesn't appreciate or tolerate siestas, even if it's locally more appropriate.
Oh, and this isn't unique to the South. It's cheaper to build a frame house in Arizona, which requires A/C to be livable, than to build an house (like an adobe house) with thick walls that moderate the temperature fluctuations.
Nor is it just A/C. Earthship designs, for example, show what is possible ... for people who are willing to put more work into daily maintenance. Which is part of the lifestyle change that's hard to do.
Okay, depressing button. :)
No he didn't, the rocks are for asynchronous heating/air conditioning, all you need to get the energy back is a water pump or air blower and tubes.
Your reply is unnecessarily dismissive and snarky. All of those ideas are easy to do projects for individuals.
The only thing you need to implement on a global/national/regional scales is a spot market for electricity accessible for everyone. Then you can lean back and watch people implement all those simple ideas and many more.
All in all, your reply is unnecessarily dismissive and snarky. Those ideas are not "brilliant ideas" (btw you should learn about correct quoting). Of course those won't solve the problem all at once, but they will have a huge impact.
> And you ignore the fact that if you use car batteries as storage for the grid, that detracts from their use to, you know, run cars.
well, actually car are parked and not used most of the time, even more during nights when there is no solar energy. And TBH this is my mid-term plan: solar panels to charge it by day and use its battery by night for lights and electric appliances (moving to an electric cold/heat pump for heating it's out of my budget currently, I'm on natural gas)
> And you ignore the fact that if you use car batteries as storage for the grid, that detracts from their use to, you know, run cars.
Most people drive about 20 - 40 minutes per day. In large cities, it is 2+ hours. The remaining 22 hours, EV is an energy sponge. Take the current peak load, produce more renewables than the peak, turn renewables to 11, absorb all the excess free energy. EV is primarily an energy storage device, some people take trips on them once in a while. None of this energy is wasted. There is no need to think of a round trip for this scenario. All energy for transportation can be free and clean, we are capturing excess production. Utilities are curtailing renewable production, this is a shame, we have built solar/wind farms, but not using free energy! This is a huge barrier for new renewables, producers have to consider growing curtailment.
> All the books and studies talk about load shaping, contrary to your "astonishment" that no-one is considering this "brilliant idea". The problems with load shaping are many.
Utilities are a monopoly, guaranteed a cost + profit formula. Utilities increase their costs to increase the profit. We see the same formula play out in health care, hospitals charge $1,400 for a band-aid. Energy can be a lot cheaper, and zero. It is entirely possible for Utilities to pay us for using our electric cars storage, they provide the best grid stabilization and smooth out demand and supply curve, flattening the peak rates. Instead of paying 10 - 20x for peaker gas plants, why can’t Americans be paid? There is a nexus of Utilities (generators, producers, distributors) and jacking up capital costs.
> All the books and studies talk about load shaping, contrary to your "astonishment" that no-one is considering this "brilliant idea".
Because these are produced by the utilities. Economists and scientists are funded by the industry to write their view. This happened and continues to happen. [1]
Lead is a gift of God. [2], this view was supported by scientists, surgeon general, AMA, public health and nearly all Govt bodies. Industry sets the rules for all of us so they can continue to extract profits for as long as possible. With this rule, we are all poisoned by lead for ~100 years. Lead poisoning is permanent! "lead does not break down over time. It does not vaporize, and it never disappears. modern man’s lead exposure is 300 to 500 times" [4]. We not only have polluted ourselves, but made a permanent toxic change for all of humanity. For what? To make the richest people a little bit richer?
Koheo's rule (put in place by the industry) was used and continues to be used for thousands of other toxins.
"Using the Kehoe Rule, Ethyl Corporation was a winner in either situation: if its product was actually safe, Ethyl would be seen as a responsible party. If, however, its product was unsafe, it would take decades to demonstrate that with certainty. The process of getting to certainty could be prolonged by challenging the methods and results and calling for more data, and while it was going on the product would continue to generate profits. Kitman indicates that the strategy taken by the lead industry, referring to use of the Kehoe Rule, similarly "provided a model for the asbestos, tobacco, pesticide and nuclear power industries, and other(s)... for evading clear evidence that their products are harmful by hiding behind the mantle of scientific uncertainty."[4] Kettering Laboratories under Kehoe's leadership also certified the safety of the fluorinated refrigerant, Freon, "another environmentally insensitive GM patent that would earn hundreds of millions before it was outlawed."" [3]
Innocent until proven guilty is for people. Should we use the same rule for stuff that harms us? How can we prove this harm when all the studies on harm are done only by the insiders?
The internet that we see today, all the things that are happening in the tech space directly result from the breaking up of AT&T monopoly. We went from circuit switched to packet switched networks, built the underlying networks to throw packets at each other."AT&T, a powerful gatekeeper, controlled innovation by controlling access to the resources needed to innovate – the wires – the physical layer of the telephone network. AT&T's view of Paul Baran's packet-switching design was: ‘It can't possibly work, and if it did, damned if we are going to allow the creation of a competitor to ourselves.’ [5]
The current configuration of the grid is a creation of this utility nexus. We must break this monopoly. If we can figure out how to sling IP packets at each other, surely we can imagine a reconfiguration of the grid that will let us throw electrons at each other. This will result in upto a thousand dollars/month saved for all of us (residential use), as well as making all the energy clean and renewable. Forever.

"Lead is poison, a potent neurotoxin whose sickening and deadly effects have been known for nearly 3,000 years and written about by historical figures from the Greek poet and physician Nikander and the Roman architect Vitruvius to Benjamin Franklin. Odorless, colorless and tasteless, lead can be detected only through chemical analysis. Unlike such carcinogens and killers as pesticides, most chemicals, waste oils and even radioactive materials, lead does not break down over time. It does not vaporize, and it never disappears.
For this reason, most of the estimated 7 million tons of lead burned in gasoline in the United States in the twentieth century remains–in the soil, air and water and in the bodies of living organisms. Worldwide, it is estimated that modern man’s lead exposure is 300 to 500 times greater than background or natural levels. Indeed, a 1983 report by Britain’s Royal Commission on Environmental Pollution concluded that lead was dispersed so widely by man in the twentieth century that “it is doubtful whether any part of the earth’s surface or any form of life remains uncontaminated by anthropogenic [man-made] lead.”

If you store the energy by heating the rocks, you can recover it to heat your house by simply blowing air over the rocks. No need to convert it to electricity, which would indeed be silly.
The same goes for air conditioning. Excess electricity could be used to cool the rocks, which then can be used to cool your house when electricity is expensive.
The detour through the rocks (or anything with thermal mass) costs next to nothing.
I am not talking about using the EV battery to run the house. I am talking about using the EV battery to run the EV. Simply charge it when electricity rates are cheaper. It's shifting the demand.
> thinking that they constitute a solution
They are perfectly and cheaply implementable, and are part of the solution.
> half-assed
I actually have a degree in mechanical engineering. You shouldn't be so hasty in your inferences.
Ridicule and condemnation was heaped upon me, all explaining how it simply must take 2 years at least.
And yet it was released 6 months later, more or less doing what I suggested.
I'm going to be proven right on this one, too :-)
Example of a proof of concept for electricity to heat and reverse via rock heating is the Siemens Gamesas Hamburg plant: https://www.siemensgamesa.com/explore/innovations/energy-sto...
Additionally, I would add that there electricity for generation of hydrogen or synth fuels for airline or seafaring industries:

In many areas wholesale markets work on a spot price basis (although players in the market can of course hedge against low/high prices), but consumers have been very reluctant to go with spot price contracts.
This will probably not be helped by the experience of those consumers in Texas who got $10000 electricity bills during last winter's storm, as the prices skyrocketed.
I suppose this could be handled with some kind of roof price (with the lost money being inserted as some kind of fixed surcharge on the bill or something like that). That would allow reaping most of the benefits of spot pricing without risking bankruptcy during a crisis.
There's a name for it: "rolling blackouts". Texas had them, they're also popular in California.
Another name for it is "shortages". Shortages happen when prices are fixed. Having fixed prices does not at all mean there's enough for everyone. Someone's gonna do without.
Of the two states you mentioned, California is also faceing a housing shortage. I would hazard that the same factors that are causing that shortage are in play for their power problems as well.
No they don't.
> See most of what is happening durring the pandemic. I can assure you the price of containers and wood have not been fixed.
The price of car batteries has doubled. But they're readily available. Why do you think all those prices have gone up?
Same as ECM for cars. You think that Ford, GM or Toyota would not pay a bit extra to be able to sell cars?
Wood saw a huge price increase but also ran out.
Right now try to source tires. Distributors don't have them, you might be able to find 1 or 2 if you are lucky but you could offer double or triple and you still couldn't buy in volume. Material is not available.
You could buy them from someone who has them. There's a price at which anyone will sell. The problem then becomes the price you'd have to charge for the cars is too much, but someone who is willing to pay that price could still buy them.
Which is why new car prices are up substantially.
If prices were set by law, this couldn't happen (legally). So then the shortages are real.
Or another example: So if I am willing to pay anything, I can get the Mona Lisa? and if you are willing to pay anything, you can get the Mona Lisa as well? There is only one.
But to bring this back to the original topic of the thread, since we have determined that money is no object, why not spend that money to build nuclear power plants.
> The idea is to not only adjust supply to the demand, but to shape the demand to the supply.
> I am utterly astonished that this is never, ever discussed when talking about solutions to fluctuating supply. Having fixed electricity rates 24/7 is simply madness in today's electricity generation situation.
It might not be the same everywhere but in France and Belgium at least, it is very common to have two rates: peak and off-peak. A signal is sent by the provider to your electrical meter (basically 220V when off-peak, 0V when peak) that can pilot a switch that turns the hot water heater on only during off-peak hours.
Some electric heaters also work on that principle, they are filled with bricks and heat up during off-peak hours then release the stored heat later, when it is needed. That's your "battery consisting of a pile of rock". However, I have lived with those things and it doesn't work at all because storing heat in anything else than water just doesn't work well. Basically at the end of the day, when you come back from work and need the heat that was stored during the night, it's already gone (and totally wasted as the house was empty). The most modern designs don't work much better. I think these only still exist because the idea seems good enough to convince people to buy them, but it's not actually technically feasible.
Anyway, everything you say is already possible in western Europe, and already done (except for HVAC, but that's mostly because HVAC in private homes isn't very common in the first place). What could be improved is to have more dynamic off-peak hours, but that's not a technical problem, everything would already work as is.
However, that doesn't help during period when there is hardly any wind. It is not as if you can stop heating your house for a couple of weeks.
I'm curious have this will play out. On a bright summer day, there is plenty of solar power. So it make sense to do everything during the day. During winter, it is better to distribute the load and move load to the night. That requires quite a bit of signaling to get right.
Also wind is the main renewable in western europe, not solar.
Having no wind for weeks basically doesn't happen, at least in the north sea.
I have a Swedish fireplace. The firebox is very small, and the masonry is rather massive. The idea is for the masonry to soak up the heat, then slowly release it long after the fire dies down. Apparently the Swedes have used this design for centuries. I don't imagine the Swedes are such fools that they wouldn't notice for centuries that it doesn't work (it does!).
People also used to put rocks in the fireplace, then pull them out to put in their beds to warm them at night. This is just a primitive method of doing the same thing.
I already do this manually. I unplug it before taking a shower and plug it again at night. Of course, doing it automatically is the only way is going to be done at scale.
This is available in the UK, using a thing called the Economy 7 tariff on electricity [1]. You have two sets of circuits on this plan. One set is the normal set that provides electricity 24/7, so you get expensive electricity when the rate is high and cheap electricity when the rate is low. The other only provides electricity when the rate is lower, such as at night (the 7 in "Economy 7" refers to 7 hours of cheap electricity at night).
There are water heaters designed specifically to work with this [2]. They have a main heating element that does most of the work, which you connect to a circuit that only provides power when the rate is low. These tanks also have a boost heating element that is on a 24/7 circuit meant to just provide any extra heating you need for hot water use during the day.
They also have tariffs that provide a fixed rate 24/7, which should be cheaper than Economy 7 during the day but more expensive at night, so whether Economy 7 saves you money depends on how much of your electricity use is at night.
[1] https://en.wikipedia.org/wiki/Economy_7
[2] https://www.cse.org.uk/advice/advice-and-support/economy-7
I've lived somewhere with storage heaters. They are horrible, practically indistinguishable from no heating at all. A large enough thermal mass would require a complete rebuild.
You, the consumer, can override it. You get to decide between donning a sweater or paying more. Isn't that objectively better than some bureaucrat simply turning off the power to your neighborhood (rolling blackouts)?
I'm not surprised to be honest. On a forum like this, you'll get a bunch of very smart people talking about something they don't know a lot about, but authoritatively. (Just look at the incredibly snarky and dismissive responses you've received)
It's certainly talked about in industry and work is going into implementing it.
I work in the electricity-tech industry but I've given up on trying to talk about things like demand response as I'm always shouted down
Never mind that the pump price of gas changes every day, especially when there's an oil refinery explosion, or glut, or whatever. It's a classic example of demand shaping via price. And it works because demand for gas is elastic.
The only time this did not work was when the government regulated oil prices and which stations got a gas allocation. Older folks like me might remember this - long gas lines in the 1970s. Gas lines that disappeared literally overnight when Reagan repealed the price and allocation controls.
All that shows is that supply is elastic and that market price varies. For the most part, demand is inelastic. You require the same amount of fuel to go to work/school and return. Now you could vary your shopping habits, go to a shopping center with several stores as opposed to the stores you like. You could put off a road trip or vacation but it isn't like either of those things are the bulk of gasoline usage.
Refinery and pipeline problems are relatively short-term events. Something like an embargo which caused the oil crisis would definitely change behavior and demand.
When you talk about allowing prices to determine who gets and doesn't get a good that is fine when it is a luxury item like graphics cards. But when you talk about the same thing for a necessity like food, water and electricity then getting priced out of the market means death.
Sorry, but that is obviously untrue. If it was true, gas prices would just go up and stay up.
> But when you talk about the same thing for a necessity like food, water and electricity then getting priced out of the market means death.
Then you'll have to accept that the inevitable shortages also mean death. Anti-gouging laws not only produce shortages, they make for less supply overall being available. (This is because high prices motivate increased supply.)
P.S. For just one example, when gas prices are low, people will drive to the store to pick up a loaf of bread. When they're high, people will combine errands and buy more items on fewer trips to the store.
https://www.bls.gov/opub/btn/volume-5/using-gasoline-data-to...
How do you explain the fact that when a refinery blows up, the gas stations still have gas to sell, though at higher prices?
And frankly, gas prices haven't changed that much. You see much different behaviors in Europe with the far more expensive gas.
Only if there was a monopoly or collusion, otherwise the competition would cause prices to fall to a point just above break even. Well, more complicated than that, prices would fall to a point where it is profitable enough for the companies involved to keep producing the goods and not switch to making something else.
>Then you'll have to accept that the inevitable shortages also mean death. Anti-gouging laws not only produce shortages, they make for less supply overall being available. (This is because high prices motivate increased supply.)
No, you can also over produce something and pay for the over production. We do that with food. That is why you hear a lot about paying farmers to not farm or dumping excess grain in the ocean as opposed to selling it.
>P.S. For just one example, when gas prices are low, people will drive to the store to pick up a loaf of bread. When they're high, people will combine errands and buy more items on fewer trips to the store.
I literally used that as one of my examples: "Now you could vary your shopping habits, go to a shopping center with several stores as opposed to the stores you like. You could put off a road trip or vacation but it isn't like either of those things are the bulk of gasoline usage."
But again, that is not the bulk of gasoline use. Most people are not going to the store for a loaf of bread, going back the next day for hamburger meat and going a third day for salad. Or even making 2 or three trips in a day. Most people don't like to spend their time in cars driving places.
Also, for shops, mall, offices, there is a prolongued pic during the day, and you can't offset that.
Also, your solution assume:
- a lot of smart connected systems (for the heating, the washing machines, etc)
- massive EV parks
- rétrofit buildings to fit those big rocks, heat them, and get heat from them
This is not trivial and would add to the cost to sell renewable energies, which are already not easy to market.
Also, in any cold climate, 'surplus of energy' is generally associated with the presence of sunlight, i.e. at times when heating the house is typically not a great priority. You want that heating on when it is coldest, which typically coincides with the lowest renewable energy production as well.
Charging and decharging your car sounds great, but it means your battery is deteriorating while you aren't even driving.
I'd be very surprised if France didn't do things like this. edit: googled it:
https://thegoodlifefrance.com/french-hot-water-tanks-tarrifs...
So, one of the "unacceptable" solutions to fighting climate change, is something that countries with the highest nuclear mix have been doing for ages.
>The simplest energy storage solution is your hot water heater. Turning on everyone's hot water heater when there is surplus electricity, and turning them off when there's a deficit, is a very low cost solution.
People want a storage solution, not a surplus use solution. Using peak sunlight or wind to heat water isn't going to be useful for a factory or server farm. The only thing that sort of load shifting helps is to diminish peak load.
Yeah, it is probably a great idea to charge your electric car during the day at work as opposed to at night. Maybe a good idea for hot water too, until you have company or teenagers who manage to use up your water in the afternoon.
The pile of rocks to store heat sounds like a nonstarter to me, unless you plan to retrofit a bunch of houses and hope that the heat stored isn't depleted faster for any reason. Otherwise broken pipes at best and deaths at the worst. Not sure how much space you would need for something like that but seems like a problem for small apartments, either the heat leakage would overheat the place or you wouldn't store enough to keep warm.
I said it was a next step. Besides, the government building code constantly adds new requirements for energy efficiency. That's why we have double pane windows today. It was mandated for new construction.
> Otherwise broken pipes at best and deaths at the worst
??? It's a pile of rocks in a box.
Then you didn't do the engineering properly.
Criminy. Of course it isn't. It's a storage device for HOT WATER.
I have an experiment you can try. Unplug your hot water heater. See how long the hot water lasts. (For me, it remains hot enough to shower for TWO DAYS.) That suggests, to ignorant me, that one does not need to heat the water in it at a moment's notice, but it can be deferred to the cheaper times of the day.
Furthermore, water doesn't have to be heated to a precise temperature. The temp of your shower is controlled by mixing it with cold water. Hence, one can heat the water to a much higher temp when electricity is cheap, further extending the "battery" effect of storing hot water.
It's not that no one talks about this stuff, it's just that it's as with all things in the utility space projects take time and a lot of the work being done is still exploratory.
No one I work with seems to think this stuff is a magic bullet either, just part of the solution (of which nuclear is another important part).
I should also note that these DERMS projects are very software reliant and I think all of us here on HN know quite well that reliability can be an issue in the software space...
NIMBY as in NOT IN MY BATTERY! :-)
The rich can afford to either pay extra or replace batteries.
A missing link is indeed a cinder block energy storage pile that could be set to preheat water going into the hot water boiler, or to cycle through water going into heating.
https://www.solarpowerportal.co.uk/news/uk_to_host_europes_l...
Long way of saying I agree with you; to make a reasonable comparison, you need to include an over-building factor to account for the variable nature of renewables. I'm not sure what that factor is (obviously it depends on a lot of variables), but I know it's been studied.
This estimation is a depressing reading:
https://www.mdpi.com/1996-1073/13/12/3036/htm
Estimated energy return on energy invested:
onshore wind 2.9:1 offshore wind 2.3:1 photovoltaic 1.8:1 concentrated solar power <1:1
In fact, for some weird reasons, I see cost reports in France factoring in wiring for wind energy, but not for nuclear.
Also nuclear assume good relationship with nations providing the fuel, which is costly: see Mali war for my country.
Getting your hands on objective calculations to compare cost for all energy types it something I seem to never be able to do.
At that price nuclear is already dramatically cheaper than coal - about half as expensive based on the analysis you linked.
The thing is, it's not clear which externalities are priced into renewables. For instance, is the cost of cleaning up this disaster where rare earth metals are mined/refined priced into wind power? [1] Burying the turbine blades forever? [2] How about the cost of the global scale e-waste problem yielded by covering the earth in solar panels which last 30 years? [3] How about power storage - all that lithium?
I'm fine with nuclear, I'm fine with wind, I'm fine with solar. There's no such thing as "green" just shades of black.
Whatever gets us off carbon fuels - yesterday. I strongly doubt the pricing is what's reflected in those charts - they tend to underprice the externalities of everything non-Nuclear. Even if they don't though, I don't really care, at this point decarbonizing is worth paying double for power. I'm not sure how good a deal we're getting is going to matter when we live on Waterworld.

I’m not against nuclear for geographies that need district heat or don’t get enough sun or wind for reasonable renewable generation, but I do take issue that it gets put forth as a silver bullet that we’re going to scale up in a reasonable amount of time when all signs point to that being objectively false. I’m violently allergic to platitudes and snake oil.
The article I linked (titled "Wind Turbine Blades Can’t Be Recycled, So They’re Piling Up in Landfills", haha) indicates that turbine blades are not recyclable. They are fiberglass, which is a mix of glass and plastic - it's long been known as one of the hardest things to recycle. They are currently buried - or burned. The latest scuttlebutt on that is Semens Gamesa has a recyclable prototype. [1] I suspect it will come, but is it priced in?
> "At the end of their working life, most blades are buried underground or burned." [1]
As for solar panels, I agree they could be recycled - up to some 90% based on some digging - but it's super expensive to do so, and I suspect it's also not priced in. 91% of the plastic you throw into the recycle bin makes its way to the landfill anyways. [2]
I don't think there is a silver bullet per se, which is why I want them all deployed ASAP.
My comment was more that I don't think the prices as reflected in your link represent the true cost of the electricity due to the varying degree to which externalities are priced in. Even if accurate, price (probably to your point) isn't really the be all and end all here. The switchover needs to happen, and in time, whatever that looks like. All this hand-wringing around nuclear taking forever to deploy a few decades ago is part of why we're here, now, without nuclear.

In France recycling is mandatory (by law).
The concrete is recyclable, and appreciated: https://archinect.com/news/article/150240752/recycled-concre...
the first link is basically your second link [2]. the rest are mostly links about that the problem from non recyclable is mostly a problem that only exists, because these fiberglass blades are dirt cheap compared to alternatives and it's cheaper to dump them in landfills. in fact in 4 european countries it's forbidden to put them into landfills. in fact a spain company _can_ recycle fiber to fiber glass to 100% (reciclalia) and they do it even for differnt uses cases (formula 1 and aerospace). of course if landfills are accepted in a country it's cheaper than to recycle. dumping is always cheaper than recycling thats why we dump so much (not just wind turbines...) in fact in germany a lot of our "recycling process" is asically thermal recycling which is not "real" recycling. we basically cheat the stats. a shit ton of stuff can be recycled if somebody wants to, which is often not the case, not even on a governement level and sometimes it's just stupid to even create non recycable waste for no reason (which happens often in the food industry because the non recycable case is often cheaper)
> It pointed to an Electric Power Research Institute study that estimates all blade waste through 2050 would equal roughly .015% of all the municipal solid waste going to landfills in 2015 alone.
While it'd be better to do something useful with them it's not a problem to put them in a landfill.

The EPR projects weren't such successes, they were overbudget and overschedule. Then an incident lead to a shutdown for examination.
See https://en.wikipedia.org/wiki/EPR_(nuclear_reactor)#Taishan_...
https://edition.cnn.com/2021/07/31/asia/taishan-nuclear-plan...
If you look for example, the nuclear reactor built in France in the 70ies and 80ies took generally between 5 and 9 years to build, with the newer and greater capacity reactors taking significantly more time.
https://en.wikipedia.org/wiki/List_of_commercial_nuclear_rea...
Keep in mind that it was at the pick of Nuclear reactor construction. These are really large projects with tons of suppliers and contractors to coordinate. There is a lot of experience and institutional knowledge needed, but which has been unfortunately partially lost with the significant slowing down of new constructions in the late 80ies/90ies.
Also, this slowing down also had a significant effect on the supply chains, often leaving very few companies key components/sub-systems.
Flamanville 3 is definitely a poorly lead project and a big outlier, but, a country re-starting its nuclear construction, the first units would probably take ~10 years to come online.
The price being very low often reflects the fact that, at that time, this energy is basically worthless/useless. And in fact, prices have even gone negative, meaning "please stop feeding this useless energy into the grid".
So low renewable prices are not necessarily a good sign, and can in fact just be the economic indicator for the limited usefulness of renewable energy.
Hang on, China also announced a couple of months ago to build 43 new coal-fired power plants.
It's not that long ago - perhaps a decade - that China was building a new coal-fired power plant every 10 days or so. Not small ones, but on the same scale as the largest coal-fired power plant we had in Australia at the time.
I mention this as a counterpoint to any 'If China's doing it, it must make sense' fallacy.
China seems to be adding ~30GW of coal, 70GW of wind, ~50GW of solar, and ~6 GW of nuclear power/year to its grid.
It makes sense if you realize
1. China pledges to peak carbon emission by 2030
2. Any increase in emission before 2030 will increase China's peak carbon allowance afterward.
3. Coal plants are cheap to build. Who cares if you only run them at 30% load factor for their entire lifespan.
4. Cap and trade between countries mean the carbon credit will worth a lot in the near future.
China pledged to peak Carbon emissions as a share of GDP by 2030. Not the same thing, given that GDP is increasing by 6-8% each year. Most Western nations already have had emissions per GDP declining for a long time.
> 2030 will increase China's peak carbon allowance afterward
China has rejected abiding by any Carbon "allowance", nor will it adopt any cap and trade system for carbon.
Outrage is what identifies a problem, but to solve the problem requires state capacity to deploy infrastructure cost effectively and at scale.
Now we have no shortage of outrage. We've got activists blocking traffic and having "die-ins" in which they lie down on the grass and sob. We have endless moaning about 'climate collapse'.
But none of that increases nuclear generating capacity. None of that deploys any reliable battery storage at scale.
So then you have the neoliberal free-marketeers thinking that if they impose taxes on oil then magically these nuclear plants will be built, just out of the free market. This is faith-based infrastructure.
But that doesn't happen, so you have the public being burdened by high taxes, then they kick the politicians out of office to lower their taxes, and nothing gets done.
Is that because the public has an emotional attachment to fossil fuels? That they love coal? No, people don't care where they get their energy. Making them care -- e.g. promoting outrage -- does nothing to deploy nuclear power at scale. Lecturing end users about how they are "destroying the plant" also does nothing. That's also just more outrage.
This lack of effective action and the substitution of outrage for engineering competency is why we still need fossil fuels for baseload and will continue to need them.
In fact we are so paralyzed by emotion and irreality that I predict that we will never recover the state capacity we had in the postwar period and instead will just end up buying nuclear plants from China and battery storage infrastructure from China, because we don't have the competency to deploy this infrastructure at scale by ourselves.
But China has state capacity. They do not have the outrage, which is why people who only value outrage think that China is doing nothing. But China will leapfrog the West in things like Nuclear power and even in the area of battery storage at scale.
It may not be according some 2030 timeline, which is again a political deadline rather than a deadline arising from a sober assessment of engineering roadmaps, but China will eventually do it because it has state capacity to act in this area and we do not. When it comes to solving big infrastructure challenges, we have only outrage.
The world wont stop warming at 2 degrees, thats just projection for 2100, it will keep warming after that.
The next generation will have to pay for pulling carbon out od the air to actually stop warming, and that's going to cost $2 for every $1 the oil industry has ever made.
I do like there is a large market to this startup. Hopefully that will result in a somewhat price-competitive reactor design. But I doubt that will happen for another 10 years.
I think solar/wind/battery will eat the lunch of any new nuclear plant in cost once it goes online.
Hoping for the best!
This may be more complicated than that, see https://news.ycombinator.com/item?id=29159944
> Japan reactivating nuclear reactors:
Japan invested on nuclear then nowadays don't want it anymore but now needs energy. One has to see them canceling their planned phase-out, as "in March 2021, only 11 percent of Japanese said they wanted that nuclear energy generation be discontinued immediately. Another 49 percent was asking for a gradual exit from nuclear energy" ( https://en.wikipedia.org/wiki/Nuclear_power_in_Japan#Post-Fu... )
> UK. Rolls-Royce gets funding
"£195m cash injection from private firms and a £210m grant" are ridiculous sums. In France Macron announced 1 billion €: given that nuclear research already burnt ~900 millions € per year (public research), a fair part of the 2.2 billions allocated to the CEA's civilian programs, this isn't decisive.
> Japan invested on nuclear then nowadays don't want it anymore but now needs energy.

Wow. To have even ~40% of the population not opposing nuclear after a national trauma like Fukushima, shows their sophistication as a people.
60% want "the nuclear power to be discontinued" either right now or gradually, and ~27% "don't know". IMHO there is a large majority of citizens wanting a phase-out.
https://www.nhk.or.jp/politics/articles/lastweek/54794.html
It also should be considered that stopped nuclear plants (its pool filled by nuclear fuels) aren't safe like no plants but similar to running plants (but I doubt majority of people know that).
I am wondering what Germany is going to do. They have bet heavily on wind & solar (apparently they haven't check how many sunny days Germany has...) with the backup from Russian gas from Nord Stream 1/2 (for some reason this gas is "clean" although burning it produces CO2). If everyone around will switch to nuclear, what I hope will happen, they can end up with the very expensive setup that is still producing a lot of CO2.
I am afraid that Germany will try to enforce ban on nuclear by European Union (what they can do, since Brexit Germany is in fact ruling UE), as the wrong investment might hurt their economy. I hope France will oppose.
The demand for power in India and China is outstripping everyone else. And it is still stuck using coal power. India and China do NOT have land (for renewables) commensurate with the population or energy demand. Also one of the biggest sources of renewable hydro power is a geopolitical flashpoint for India vs China (https://www.indiatoday.in/news-analysis/story/china-proposed...). Almost a hundred soldiers died in an India vs China battle recently around this area.
Both India and China have unilaterally rejected COP26 restrictive measures from developed nations... simply because it is not possible to reduce the power demand coming from populations (the size of Europe) being lifted up from poverty.
The only answer for the next 50 years is nuclear tech. And France is literally the only game in town right now. So let us pray, this happens sooner than later. You do NOT want coal from 2 BILLION people in the atmosphere.
You are misunderstanding the growth in power needed. If India and China move towards electric vehicles..... just New Delhi has 12 million cars. Just to compare, London has 2.6 million cars. New York has about 4 million cars.
I don't think people grasp what 2 billion people really means.
“China has reported overnight to be planning 150 new nuclear reactors over the next 15 years — more than have been built around the world since 1980 — a signal that uranium production needs to be stepped up, fast and soon.”
That’s a reported planned investment of $440B.
https://smallcaps.com.au/china-supercharge-uranium-race-150-...
And actually doing that as we speak, instead of "planning".
The last point, we just don't know how to build nuclear economically anymore. The process is so bureaucratic and slow it becomes infeasible to finance without major interventions. Letting Chinese or Russian companies build it from the standpoint of Europe is a geopolitical challenge and a security risk.
All this time and money would be perhaps spent better elsewhere. In Europe, we are not able to build a nuclear powerplant in 15 years, so that is lots of time for research and development and even building something useable. It is very likely, most of the renewable sources will become more economical and nuclear less even less. We might devise a scheme to store energy by e.g. splitting salt (NaOH) into sodium metal, hydrogen and oxygen and later combining sodium with water to NaOH again, while getting hydrogen as a byproduct and lots of electrical current. It is a simple process, we "just" have to scale it and develop it further. The first half of it is well known for 100 years and was used at industrial scale. Currently, we just split NaCl directly to obtain sodium... The second half is described in patents by Lockheed-Martin that are long expired. You can read more in this diagram: https://www.orgpad.com/s/iV3vbi
Btw. Slowakia has a lot of nuclear too and here in Czechia, we have a conversation about building new reactors in Dukovany too. For Czechia, the approach seems to be misguided as you can read here (Google Translated from Czech): https://denikreferendum-cz.translate.goog/clanek/32812-cesky...
The usual pro-nuclear argument says that nuclear plants are only unsafe if managed incorrectly. However, the West doesn't have the political or economic framework to ensure they will get managed correctly: if you are the leader of the executive of some country, are you going to decomission a plant built 30 years ago that gives the country a lot gW of energy and raise energy prices for everyone, or are you going to risk the very low chance of a serious accident to keep prices down and pass the ball to whomever governs next?
If nuclear is the future, we need an effective process of automatic decommissioning that can bypass governments. That process doesn't exist yet.
The last delivered reactor was Civaux-2 (generation II), in 1999. See https://en.wikipedia.org/wiki/Civaux_Nuclear_Power_Plant
Then in 2002 the project Flamanville-3 was launched (a generation III reactor, the "EPR", first one of its kind), and the building phase started in 2007. It is a major failure, not delivered, at least 11 years behind schedule, and will cost at least 19.1 billion euros (initial budget: 3.4 billions €). See https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plan...
However, they were not expecting this much. The reasons that they are pushing are:
1. Lack of proper trained personnel
2. More constraints imposed during the projects due to Fukushima
3. First design of that kind
And as you said, the last nuclear reactor to be finished in France was 20 years ago[0]. The people who worked on that last plant were probably the one who worked on plants during the 70s, 80s and 90s and retired right after. It fits with reason 1.

It was scheduled to take 54 months to build when construction started in 2007:
https://web.archive.org/web/20110613091002/http://www.neimag...
The last reactors to enter commercial operation in France, the 2 units at Civaux Nuclear Power Plant, took 13 and 11 years from construction start in 1988/1991 to commercial operation in 2002:
https://en.wikipedia.org/wiki/Civaux_Nuclear_Power_Plant
I wonder if EDF succumbed to hubris in thinking that they could build a new reactor design twice as fast as the last-completed reactors, or if they published optimistic numbers because they thought that there was more institutional tolerance for constant slippage than for estimating unhappily large numbers right at the start.
At the time France was simultaneously building many reactors, see: https://fr.wikipedia.org/wiki/Liste_des_r%C3%A9acteurs_nucl%...
Some say that Flamanville-3 is a failure because it should be built along with many other reactors. This seems ridiculous to me, as if the problems (lack of adequate applied skill, bad project management... there is a complete official report about the causes, written by M. Folz) would be alleviated by parallelizing projects (it would instead worsen their effects and add delays).
> if they published optimistic numbers because they thought that there was more institutional tolerance
In France institutional tolerance for the nuclear industry is at its max. Start in 2007, to be delivered in 2012, nothing delivered in 2021 and 5.6 times over-budget... and no-one even talks about calling it off. Even better: M. Macron wants to start new projects!
At this point, it's more of a jobs-program than an energy-program - like a lot of US defence spending.
No, it officially is a "tête de série" (meaning among the firsts of a series). It cannot be a prototype because this very model, the EPR, was sold to Finland and the corresponding project (Olkiluoto-3) started 2 years before Flamanville's.
> the one who worked on plants during the 70s, 80s and 90s and retired right after
In such huge heavy industry projects occupying tens of thoosands persons there is a constant stream of newcomers. Moreover this industry must maintain existing (exploited) reactors, and a non-neglectable portion of skills needed when building are also needed during maintenance. Also: many critical specialties, especially outside the nuclear isle, are qualifications built upon a non nuclear-specific trade (concrete, welding...): a "standard" professional can be trained in nuclear-specific skills in months. In any case the industry (which isn't exactly a low-cost lo-margin one...) has to manage human resources, and to find ways to maintain critical and very specific skills.
Honestly I don't know if we can really build nuclear plants anymore, at least for a reasonable cost in a timely fashion.

- shut down the Fessenheim plant, one of the most reliable one. Yes it was the oldest, but not by far, and reports from the nuclear authority are pretty clear that this plant was in a much better shape than others built just a few years afterwards (Bugey, one year later which is now older than Fessenheim was when shut down, and Blayais started 4 years later).
- promised to reduce the share of nuclear in the electricty mix to 50% by 2025.
- shut down Astrid, the French research project for 4th generation nuclear (which is the only long term viable path for nuclear, since there will never be a shortage of fertile material (U238 or Thorium) whereas fissile one is pretty limited. Breeding reactors also solve the very-long lived nuclear waste issue).
He did all of this when he was trying to seduce electors from the green party. Now he don't seem to care about them, but who knows for how long…
Fessenheim had been a thorn in the back of previous governments for years. Sometimes political move are not logical from a technical standpoint but can be seen as intermediate step in a larger plan. I don't blame him for that.
Astrid though seems to be the real mistake. The new CEA boss at the time said that[0] we don't need that kind of reactor because uranium is cheap as nobody wants nuclear anymore since Fukushima. This is such a stupid reason that I cannot believe to be the real one.
[0] https://www.lefigaro.fr/sciences/nucleaire-le-patron-du-cea-...
Regarding the closing of Fessenheim, it seems like a sensible decision. The central was designed to last 40 years and long exceeded its expiration date. In the last 10 years it had roughly one incident per year with graver and graver consequences. And in any case, France would have started lose a lot of money because, due to the geographical position and the risk it pose, its neighbours, Switzerland and Germany were not really happy with it and had started to repetedly attack the decision to maintain it open in courts.
The fact that a politician had to take this decision (and not engineers) is in my opinion the most shocking part. It shows that the ANS probably became complacent with the state of security of centrals. Probably similar to finanicial markets or aviation regulators. And generally when that happens it's the begining of catastrophes.
I wish it was it, but it's not what's happening. Macron is currently campaigning for his reelection and has decided to adopt a really conservative tone for his campaign: it's all about “fighting islamism”, reducing welfare, etc., etc., the strong nuclear narrative fits clearly in this tone.
> Regarding the closing of Fessenheim, it seems like a sensible decision. The central was designed to last 40 years and long exceeded its expiration date. In the last 10 years it had roughly one incident per year with graver and graver consequences.
It was designed for 40 years, but so did every other plants that were given a extended lifetime approval. Actually, it's not uncommon at all to design a power plant with a specific lifetime in mind, and extending it afterwards when you realize it hasn't wore out too much (fun facts, some systems were dead long before reaching the 40 years span they had been designed for, and have been replaced even though it wasn't part of the original plan). And as I said, Fessenheim was one of the best plant of that generation when it comes to incidents, it had a much better rating than several plants built a bit later and which will still be in service for the next decade.
> And in any case, France would have started lose a lot of money because, due to the geographical position and the risk it pose, its neighbours, Switzerland and Germany were not really happy with it
I don't know where you take that from but in reality, France have to pay a huge sum of money to Germany as compensation for the shut-down because part of Fessenheim's plant (17.5%) was owned by the land of Bade-Wurtemberg. The overall price that will be paid until the end of the compensation period (supposed to last until 2041) is still unknown because it will depend on the market price of electricity on that period, but it's expected to be between a faction of billion to a few billion euros.[1]

This is indeed a serious risk with regulation authorities, but in the case of the ASN it's proven pretty reliable in recent days: rthe 50 years lifetime extension was granted in exchange of a huge overhaul of the existing plants (“le grand carénage)” costing several billions, to add a lot of new safety equipment, most of them designed with the Fukushima accident in mind.

Perhaps we can invite Slovakia or Russia to build in other countries, but there's no knowing if they could train local workforces accomplish what they have.
Maybe this whole outsourcing of all technical skills and manufacturing actually has something to do with it?
Maybe treating staff as disposable cpgs hollows out skills untill the companies can no longer do anything right?
HS2 spent ungodly sums on "consulting" and management fees to do stuff that, back in the day, would have probably been carried out by a couple of commandeered civil servants. But I'm sure all their Word reports have nice headings and lots of "holistic" something.

And if you live on the West coast, it was recently discovered that an essential chemical used for tire durability and safety causes mass deaths in salmon. (Or rather, the chemical breaks down into another chemical, which causes mass salmon death, and probably other fish death too).
I will appreciate never having to hear a damn diesel truck again, however. Those things should be taxed heavily for noise pollution in addition tk their massive particulate emissions.

But liquid fuels are incredibly convenient, so maybe they will be worth the high price in certain applications. For example in jet engines for airplanes.

> Median construction time required for nuclear reactors worldwide oscillated from around 84 months to 117 months, from 1981 to 2019 respectively.
https://www.statista.com/statistics/712841/median-constructi...
The timeline ballooning as all external parties take their time weighing in and covering their asses, and costs associated with idling construction waiting for same, are getting ridiculous.
Either it's a priority (in which case everyone should treat it as such), or it's not (in which case we should accept we just can't build non-priority projects over a certain scale).
Other than the fact that the federal government fining the federal government has no actual effect, all that making a high-legal stakes response timeline with impossible to concretely define completeness requirements would do is increase litigation and litigation costs around such projects.
If the construction requirements of 1980 are sufficient for a plant operating ten years from now that came online in 1980 then the construction requirements of this year should be sufficient for a plant operating ten years from now even if it hasn't come online yet. So the obvious fix for this is to use the requirements as of the day construction begins rather than the day it ends.
The plants that have had issues were known to be the oldest and most vulnerable ones.
Tihange is a good example of the same political inaction that gave us this climate crisis. It has nothing to do with cutting corners, nor about "designing and running these things". It is (political) complacency, not mismanagement of the plant that's the main problem.
If you forbid fossil fuels at a point in time (say 2030), the energy market will know ahead when demand will exceed supply. There aren't better incentives avilable if you want the mega projects built on time

At least one of the reasons why solar and wind really got off the ground is because the marginal cost of one more installation is not very high. Panels on the roof may not be the most efficient, but they are actually feasible for a homeowner to purchase and install.
The nuclear industry will be lucky if its able to pull off enough construction to replace reactors that age out. There's no chance of nuclear becoming a backbone of our new grid, when we would need to produce 400GW of new nuclear. The napkin math does not work out.
However, renewables and storage are scaling their production at just barely a high enough rate, if we continue on the same exponential growth curves we have been on for the next decade.
Hopefully production will scale even faster, now that solar is the cheapest form of new energy.
And storage is quickly getting solved. California has gone from almost nothing to more than a GW of storage in a year, and is adding more GW at the moment. Even the "free market" in Texas is choosing to add many GW of storage, even more GW of solar and wind, and almost no new natural gas. And in the US, the majority of new solar projects include storage now, because for a long time there has been more DC production power than ability to convert it to AC, and a few hours of storage makes financial sense because storage has gotten so cheap. As it gets cheaper, there will be bigger an bigger amounts of storage added to every renewables project, on site.
Meanwhile we can't build nuclear in Western countries anymore. France can't, the US can't, the UK is likely going to fail.
The problem in the nuclear industry is that they are stuck on getting even first of a kind plants out. The idea of scaling up to hundreds of GW in the next few years is a pipe dream for the us and Europe. Maybe China will be able to build their 150 planned reactors, but even if they do they will be building far far more renewables than that.
The production capacity of modern Western economies is very well suited to wind, solar, and storage. It is absolutely awful at massive construction projects, like nuclear. Construction productivity has barely changed at all since the 1970s, while other fields' productivity has soared. We should take advantage of that.
And this ain't even talking about the new types of super cheap long duration storage that have high energy/power ratios. There's iron batteries in both traditional solid forms and in flow forms. Noe that the market need is becoming apparent, there are new chemistries being developed all the time that are suitable for stationary storage but not as well suited for cars and other mobile applications. Which is fantastic, as we can then reserve all that quickly growing production capacity for transport.
France is around 70% nuclear and 15% renewable (mainly hydro). Maintaining the same level of emissions would mean going to 85% renewable, not 75%.
> we can get to 75% renewables without storage.
Not unless we build 50GW of fossil fuel plants. Is it what you suggest?
France has no need to transition when it comes to electricity. We're already almost as low emission as possible so there is no urgency. What we need is a medium term plan, because the plants may start being decommissioned in around 10 years (unless ASN give them the right to run for ten more years, which isn't completely impossible: in the US, some plants from the same technology (PWR) is allowed to run until 70 years!).
And btw, solar in France makes zero sense except in the Mediterranean region, the weather is just not good enough…
From your perspective, when the sun isn't shinning, you just don't get paid. But from the grid perspective, when you don't produce electricity somebody else has to do it! And since the sun isn't shining that much, the grid owner has to have another power supplier most of the time (or batteries).

The stories in the US about VC Summer and Vogtle construction failures do not point to government regulation being the problem, they point to basic flaws throughout the construction process. Design of the AP1000 that is "unconstructable" according to the EPC contractor, who then goes on to build their own unproven design, which then requires an external check. The problem wasn't that the design had to be certified by the government, the problem was that design wasn't in touch with construction.
We used to be able to build things quite quickly. E.g. The Bay Bridge was built in 5 years for $77 million (~$1.5 Billion today) in 1931-1936. This is not ground breaking, but law passed to bridge opening.
Just replacing the Eastern span cost $6.5 Billion and took ~18 years to build (1995-2013) from law passed to section opening.
Decisions have consequences.
In some cases EDF even planned building more reactors from the very beginning, for example at the nuclear power plant of Belleville-sur-Loire: everything was planned for 4 reactors, but only 2 were built. So they can build two extra right there, no need to find a new site.
The current not so small problem is that EDF needs to learn how to build nuclear reactors again. That's what they are currently doing, at great cost and great delays... But if the political will is there, they can start to break ground quite literally tomorrow.
I don't know exactly how true this is but I believe gas usage for heating is much rarer in France than other countries. They have a lot of electrical storage heating due to the cheap off peak baseload that nuclear gives.
- pollution and waste - it's limited
At the current consumption, uranium would only last 80 years, if all the countries start to build new power plants, won't last more than 2 decades before it's depleted, and we will have the same problem again.
nuclear power is not a solution, is just a small patch.
Thank you for pointing this out. People blithely assume that U235 is available in unlimited supply when it is not.
My own view is that it is a useful partial interim solution that buys us some time. That is worth quite a lot.
Interesting. I had not heard this before, and Wikipedia seems to somewhat agree. From https://en.wikipedia.org/wiki/Nuclear_power#Uranium_resource...:
> As of 2011 the world's known resources of uranium, economically recoverable at the arbitrary price ceiling of US$130/kg, were enough to last for between 70 and 100 years.[60][61][62] In 2007, the OECD estimated 670 years of economically recoverable uranium in total conventional resources and phosphate ores assuming the then-current use rate.[63]
> Light water reactors make relatively inefficient use of nuclear fuel, mostly using only the very rare uranium-235 isotope.[64] Nuclear reprocessing can make this waste reusable, and newer reactors also achieve a more efficient use of the available resources than older ones.[64] With a pure fast reactor fuel cycle with a burn up of all the uranium and actinides (which presently make up the most hazardous substances in nuclear waste), there is an estimated 160,000 years worth of Uranium in total conventional resources and phosphate ore at the price of 60–100 US$/kg.[65]
It was expected to cost 3.3B€, but in the end will probably cost around 19B€.
Hoping for companies like NuScale, maybe they can get a continuous operation going and churn out cheaper and cheaper plants.
What has been learned at Flamanville that could be transferred elsewhere?
However this is all assuming that Hinkley Point C stays in budget and on schedule, which would be a strange assumption to make given recent history.
So I'm not sure anything is being learned, or construction capability is increasing. Which is a shame, because that area of the world is the area with the strongest need for nuclear. The rest of the world will get by fine without it. And for that matter, it's likely that Northern Europe can build enough wind and storage to get around their need for nuclear. But it all would have been a lot easier if the nuclear industry was anywhere close to delivering on its lofty promises.
The gen 3 design is, depending on how you view it, 3 years old. It was found to be too expensive and too complex.
There exist new version of gen 3 reactors and there are design for gen 4 reactors, both claiming to solve many of the issues of the old gen 3 reactors.
Those 6 new one was the news from 2020. The one we see in the article is unspecified and could be a reference to the 6 EPR 2 or something else. Same is true for the 150 Chinese plants being planned.
The biggest fault in the old EPR design process seem to be the mid-construct patch that occurred in 2012 as a result of the Fukushima accident. Other issues seems to be related to goals like "world’s highest-output nuclear plant". They decided to use rather exotic form of steel, within the upper limit of what can be created. Given the decision of making the highest-output nuclear plants, and there are only a few places in the world that can create and work the kind of steel that the design require, the budget did not work. In addition, the exotic nature of the material makes it difficult to weld correctly.
The open questions I see is if EPR 2 also require similar exotic materials, if the exotic materials has improved in availability and price, and if the experience in welding it has improved to the point where fewer mistakes are done. It is also possible that by not trying to achieve new world records in plant size and output, the budget might be more reasonable. The world largest and highest wind turbine might be a nice research goal, but building one at the limit of current material would not be my first choice if costs were a priority.
He is a realist, but in this field we need to go beyond and to open big money for the research into small and decentralized nuclear power.
Every citizen have to know the pros and the cons, and be educated to the risks. Energy provide good living standards, but we have to know the drawbacks and we have to account for externalities in every business model.
This will be the only way to keep our standards of living and keep an habitable home.
> This will be the only way to keep our standards of living and keep an habitable home.
Jancovici uses physics and maths to prove we definitely won't have western standard of living for 8B people. Even for 2, not for long.
In France there are reactors, now they are OLD.
OLD is a cost, and also a risk.
France already has gaz (cost is hight), or hydrolic (water daws are all in use at its max in France), but it seems France doesnt want to go the german way and switch on the coal power plants.
The press article mention green peace, while most of people think gren peace are communicant people who doesnt get aware about science news and will applause germany for leaving nuclear (but going COAL) and blame france for keeping nuclear (but having low CO2 energy ratio) like if wastes are worst than CO2 while CO2 is nowday issue.
Government tryed to open the energy market in France, but since it has done that, the consumer prices are only getting highter and highter while the historic company EDF is making profit, and not the new comers who are often at the edge to termination plan. Also, Having a company not being EDF (governement has 80% part of it) to own a reactor is a risk, because profit always come first for a company.
Having new reactor will give more low-CO2 emission energy and give more time to have more decent work (r&d) on renewable energy and stockage (not daws since we already use them all here) probably.
There are risk to have reactor, and also wastes, but the CO2 costs look the best until there is something else.
PS: I'm not a macron side voter; I think many french people think like this; I'm not backing anything with source, because it's just what it is on people minds i guess and i agree a bit to that; so I'm just sharing this here for the discussion
I promise you no mutant monster will arise from the earth to destroy civilization.
The hysteria over where we store this waste is really silly. Even if spray it into the air all over the planet, we'd still release 1/100 the amount of thorium and uranium than is currently being released into the air by the world's coal plants. Therefore even if we spray the waste into the air, it's still safer than coal. Burying it in the ground is much, much safer.
There is a big difference between the naturally occurring isotopes of thorium/uranium, and what comes out of a reactor.
> Even if spray it into the air all over the planet, we'd still release 1/100 the amount of thorium and uranium than is currently being released
One thing I cannot fully communicate with posts like this, is that it's not clear what the intention is. By these posts, I refer to posts which uses emotional summary, backed by human loss that has the subject involved. Then leave no trace of the actual rational conclusion from the facts.
It looks just like an intentional emotional manipulation, which plagued most US news reports. This type of approach, makes rational discussion very difficult to progress.
Edit: Look at the child reply. See what emotion brings to a discussion. From nuclear energy to illegal disposal of nuclear waste, then to holocaust. The emotion is increasing, but the subject of the discussion is dissolved in the process without any trace of respect to the other parties in the discussion.
Emotion sucks the rationality from the discussion, and literally deprive the common grounds between people. In the end, achieve nothing.
Then, years later, you read HN comments downplaying the effects and the affected with the same types of arguments as Holocaust deniers.
It's emotional, but it's not manipulation. It is the reality how it happened.
Of course one can reach a destination by heading in the opposite direction, because earth is round; but it would be awfully wasteful.
One can also influence people and make things happen by being super emotional/ideological, in other words, being with super little rationality (not that they are incapable, they just orient in that direction naturally). But that would be awfully ineffective.
You go away from arguing about the topic on hand and instead proclaim that all your opponents arguments are not valid. It is basically a "You are stupid and I do not have to listen to your points".
Further true rationality does not define any goals, because it is just about using reason to come to conclusions or for deducting how to best get to a goal. People that claim to be ideology-free are very dangerous, as they are not ideology free, but cannot accept people seeing different goals.
You can see this romantic view of science in a lot of nuclear power advocates. Nuclear power has, standing for progress and a representative of science, become the goal in itself that is needed to be protected.
To come back to the dumping of nuclear waste: For a while that practice was not even illegal, contrary to what you claim. Nuclear power leads to nuclear waste, which has to be handled properly. Because that is expensive, there exists a high probability for improper handling to happen. Given how often improper handling of nuclear waste has happened, it seems like a systematic problem that is also very likely to happen again, as nuclear waste is an issue that stays for a very long time, which probably also means different political systems.
Your argument that improper handling is only the fault of the bad actors that in the end acted out the dumping is invalid. It ignores on one hand, that the responsibility for toxic waste lies with the producers. If they did not take care for a proper disposal it is their fault. On the other hand it ignores the reasoning of the people that do the toxic waste dumping. Usually that happens in poorer regions and people do it simply because they have no alternative way of earning money.
But where did I accuse "lack of rationality"?
I was saying the post has little context, and based on relatively mainstream mental response, it's reasonable to assume that the OP intends to arouse emotional response through association, instead of lay out it's argument.
> You are stupid and I do not have to listen to your points
...
I was saying that the OP did not provide context and concrete meaning. How is that not listening?
If someone refuses to talk, then it must be the others is "not listening"?!...
> Further true rationality does not define any goals, because it is just about using reason to come to conclusions or for deducting how to best get to a goal. People that claim to be ideology-free are very dangerous, as they are not ideology free, but cannot accept people seeing different goals.
I guess this applies to the grand parent post more than mine?
> You can see this romantic view of science in a lot of nuclear power advocates. Nuclear power has, standing for progress and a representative of science, become the goal in itself that is needed to be protected.
Hah?!
Me and every post I saw uses climate change as the main driving force.
I have never seen anyone claim that nuclear is just plainly noble or something.
Everyone is claiming that tech advanced and nuclear is safer and should be acceptable, if it were to be assessed relatively evenly with alternatives...
> Your argument that improper handling is only the fault of the bad actors that in the end acted out the dumping is invalid
I never argued this
Or I never intended to argue this. But human language is complicated, I blame myself equally as anyone who misunderstood.
Back to bad actor.
No, bad actor in large scale is just interests misaligned. I never doubt there is fundamental issues with nuclear that caused dumping. But let's discuss in current context: emotional public are under skewed image of nuclear.
> But where did I accuse "lack of rationality"?
In this part of your post I believe. It leads people to that conclusion:
>> Edit: Look at the child reply. See what emotion brings to a discussion. From nuclear energy to illegal disposal of nuclear waste, then to holocaust. The emotion is increasing, but the subject of the discussion is dissolved in the process without any trace of respect to the other parties in the discussion.
>> Emotion sucks the rationality from the discussion, and literally deprive the common grounds between people. In the end, achieve nothing.
Frankly, I don't know what to make of it. Sometimes people build arguments with enough cruft to fog their main points and intentionally mislead people and sometimes it's not intentional and they don't realize it. HN also loves to play the definition game sometimes.
I'd just say this:
> But let's discuss in current context: emotional public are under skewed image of nuclear.
Do we have a poll or something to assess where people stand regarding nuclear ?
I dont know what to say.
The child post literally is just full of emotion and none of rationality.
I never said the author not capable of rationality...
> Then, years later, you read HN comments downplaying the effects and the affected with the same types of arguments as Holocaust deniers.
> It's emotional, but it's not manipulation. It is the reality how it happened.
But those things happened where I lived when the Chernobyl cloud passed over. See https://en.wikipedia.org/wiki/Effects_of_the_Chernobyl_disas...
Of course the writing style is not the same as the one used in a study abstract and probably the poster has some emotions about it but he's not writing irrational or emotional things. I do agree making a comparison with holocaust deniers approaches the Godwin threshold though. I'd have used climate change deniers instead.
Also, one can write rational things while still being driven by emotions.
> Mr Burns was the most environmentally responsible Simpson's character and likely a real scientific expert.
then you really need to watch the show again.
He hid nuclear waste in trees.
It doesn't necessarily mean nuclear is intrinsically bad, it means humans can be really bad at handling it.
You want characters like Burns handling a nuclear revival ? Then that's a really good argument to be against nuclear.
* Portrait nuclear energy tycoon as the only villain is sad. Because it reflects a unconscious strong mental imprint of nuclear being fearful.
* The show can portrait coal miner. Instead of hiding nuclear waste in the tree. Coal miner can pollute the sky as some form of "sky painting".
The setup itself is sad.
There is no intention to argue that that bad guy is good, or is better suited to revive nuclear energy.
> Mr Burns was the most environmentally responsible Simpson's character and likely a real scientific expert.
And it's clearly wrong.
Now:
> * Portrait nuclear energy tycoon as the only villain is sad. Because it reflects a unconscious strong mental imprint of nuclear being fearful.
From the top of my head the show had a corrupt and inept chief of police, a corrupt mayor, a crazy homicidal clown, a fat tony hanging around freely and an unstable clown. Burns was not the only villain.
He was not a villain because of being a nuclear energy tycoon. He was a villain because of his actions (greed and arrogance and grandeur disillusions).
Now of course by association you could defend the idea that's it's a full blown attack on nuclear. And yes there is a strong mental imprint of nuclear being fearful in the US but I'd argue it has more to do with real life events and... I don't know.. cold war era craze for home bunkers to survive an nuclear winter than a cartoon that started at the end of the 80's and uses a badly managed nuclear plant as a laughing device (humor device ?) not even present in every episode.
> * The show can portrait coal miner. Instead of hiding nuclear waste in the tree. Coal miner can pollute the sky as some form of "sky painting".
Are you trying to build the argument that being against nuclear means being for coal ?
Anyway, apart from that three eye fish I don't recall the springfield nuclear plant had incidents that had lasting consequences like Chernobyl or Fukushima had. So apart from being comical...
I don't see where in the show it transpires that the depiction of the springfield nuclear plant reflects a " strong mental imprint of nuclear being fearful".
I can tell you that what you read are not what I meant. They are actually (to me) implicit extension from the words' face meaning.
And I can assure you that what you mentioned is what I meant as well.
Some in the community seem to think that the market will 10-20x due to the world waking up to the immediate, pressing need for nuclear. (Insufficient wind/solar capacity, storage, transmission, etc.)
There are also some interesting behaviors going on in the uranium market, where certain players are buying up all of the supply. It's short-squeezeish in nature.
China announcement, French announcement. US uranium exploration. Lots going on.
Any investment that you were gassed about a few months ago would be doing well.

>France derives about 70% of its electricity from nuclear energy, due to a long-standing policy based on energy security. Government policy is to reduce this to 50% by 2035. [1]

There's been a lot of talk about nuclear (both fusion and fission) recently, and it's great news!
EDIT: to be clear, I'm not asking this as a backhanded question. I'm genuinely curious why this is not seen as a "solved problem", at least in a country with relatively strong government institutions
Just 1 long term waste storage has ever been built in the world, plant productivity has always been relatively low (initial manufacturing delays, refueling, minor accidents, refurbishments), many anti-proliferation techniques just over-produce rad-waste.
Oh, and if we were to buildout nuclear globally how long would the ore reserves last?
In emerging economies new designs can be used, but they'll probably have to be trialed in a developed economy. You could also pursue economic policy that has developing economies fund the research instead of letting them expect handouts.
You're saying there were no actual, serious problems with nuclear plants?
> Existing plants work and are defensible.
That's survivorship bias to a degree: Te plants that work and are defensible are the plants you see. It's also a bias of sunk costs: The surviving plants could have been way over-budget and late, but it's still worth operating them.
Compared to other forms of energy generation, measured in illnesses, injuries, maimings, and deaths, past and plausibly attributed to the future, per KWH? Not really, no.
Is nuclear power generation dangerous? Yes. Is all power generation dangerous? Yes. How dangerous is nuclear power generation compared to alternatives? Not very.
It's pretty accurate to say that nuclear fizzled due to FUD. The conversation ended after the answer to the first question was 'yes'.
This is due to that fact that there are no viable plans for long term nuclear storage to calculate the cost of.
Is this not "wrong" in a very material way?
If we fully burn all available nuclear fuel, it will last about 5 billion years. [0]
[0] https://web.archive.org/web/20130114062518/http://sustainabl...
Somewhere I read (sorry for the lack of sources) that with single-pass fuel use, known reserves would only last a couple decades, a century at best.
Why. What risk of proliferation is there in France, UK or U.S.? These states already have nuclear weapons.
If you get any expansive policy and process wrong, the negative global consequences are dramatic and long-lasting. So, first, do no harm.
1. Net online time for nuclear isn't particularly bad, especially when you consider that other alternatives too go down. [1] Of course you'll need some extra capacity/more plants, but that was anyway the case.
2. I feel this is probably the strongest point that can be held against nuclear. Short-term fuel management is not an issue/already figured out, and climate change is a much quicker risk in the next 50 years, so I'd argue it's still better to go 0-carbon instead of finding a perfect solution right now.
3. I'm not sure if you're referring to proliferation of the fuel or technologies, but both are reasonably well-developed fields that France should not have major problems.
4. Similar to point one - nuclear accidents vs risks/deaths from coal is like comparing flight safety with cars. Sure, airplanes feel unsafe but are statistically MUCH safer than cars. Chernobyl and Fukushima were both avoidable (though that can admitably be said for a lot of accidents). Deaths from pollution itself are in the millions instead. [2]

Some reactors don't have this risk, but I'm not read on it.
Spent fuel from nuclear power plants-- probably the more vulnerable point in the supply chain-- is nonetheless difficult to the point of extreme expense & impractical to refine to weapons grade. You would need such large quantities that it would be extremely difficult to steal enough without notice: Someone is going to notice the 200,000 lb cask leaving a storage facility. Then the refinement process is difficult, requiring immense sums of money to built the significant infrastructure required for refinement. North Korea, the newest nuclear power, got there with significant help from the Soviets extending back in the 60's and it still took them decades to get there.
This is all on top of the fact that any modern plant designs use feedstock fuel that is even harder to refine into anything weapons grade, and is much more efficient to the point that spend fuel refinement difficulties dwarfs the above roadblocks for fuel from older designs.
Dirty bombs are more problematic, but also significantly less destructive, and suffer from many of the same logistical hurdles, notably that the material most useful for a dirty bomb is also material that requires massively robust precautions to ensure the thieves don't kill themselves with radiation exposure long before any chance of making use of it. Less useful material that requires fewer precautions is not practical for dirty bombs without significant refinement capacity.
All of this at a time when real measurable deaths from fossil fuel powerplants, their pollution, and their industrial accidents, are themselves more dangerous, right now, than theoretical & difficult to achieve usages of fuel from new nuclear power plants.
Some reactors don't generate weapons-grade isotopes when operated as intended, but if you control the reactor, my understanding is that it is easy to modify it so that it does.
There is no technical safeguard against nuclear proliferation - all of them are political.
I'm pro-nuclear, but the need to be circumspect about safety is real.
I always think of a Bruce Cockburn song, "Radium Rain", written in 1986 when visiting Germany right after Chernobyl:
Every day in the paper
You can watch the numbers rise
No such event can overtake us here
We're much too wise
In the meantime, don't eat anything that grows
And don't breathe when the cars go byIt depends. Are you comparing deaths per kilometer, journey or hour?
Deaths per billion
Type...Journey...km.....Hours
Bus........4.3........0.4.......1.1
Rail.......20.0.......0.6.....30.0
Car........40.0.......3.1....130.0
Plane...170.0......0.05....30.8
Do you want to know the likelihood of dying on your next trip, the next kilometer or in the next hour?
And it’s not as easy as recycling empty glass bottles… the French struggled to keep their breeders online and keep them economical (but then the military we’re still happy so…)
Hard to say tbh. But these reactors probably aren't offline as much as you think. They shut down for 1 month every 18-24 months for refueling.
> 2. Spent fuel?
France is the world leader in this regard. Remember that 17% of France's entire power comes from _recycled_ nuclear. But if you want to see what their entire nuclear waste. This is _decades_ worth, and I'm betting much smaller than you expected.[0] (coal is doing this on a a daily or weekly basis). Just for fun, let's look at Russia's too.[1] We're literally just talking a warehouse. People vastly overestimate the waste and what to do with it. It is fine where it is for hundreds of years. The only "problem" that we have with "long term storage" is how to store it somewhere where if somehow all knowledge was lost that future humans with no radiation detecting equipment could accidentally release waste (quite a high bar, and not one we're concerned with other long lasting waste like lead or heavy metals). We have a few hundred years to figure that out.
> 3. Proliferation risk?
None? It is France. They already have nuclear weapons. But while we're talking about it, Megatons to Megawatts[2] has been the best deproliferation project in history, reducing the number of nuclear warheads by over 20,000.
> 4. Accident mitigation?
Very low. This is also over estimated. We have a very early reactor which no other country besides Russia built because it had the ability to explode. And we have another event where we didn't know earthquakes could happen of that size until basically right before said earthquake happened. These are major disasters, but the two should not be conflated. Even including these, they are far less environmentally damaging than the fossil fuels we've been using. The major problem with nuclear is that disasters are both temporally and spatially localized. There's advantages and disadvantages to this in terms of dealing with the consequences. On one hand, it is a lot to clean up. On the other hand the country that created the disaster is the one that suffers the most (as opposed to what we're seeing with oil spills and the entire climate crisis, which is not temporally localized and thus the danger is not weighted properly).

More nuclear trained personnel, designs, materials, and plants mean more opportunities for someone to acquire technology or materials.
I'm sorry, but you're just spreading FUD. There's a reason the Iran Deal is a fine deal. But I don't expect anyone to understand this without 1) reading the fucking thing and 2) actually understanding nuclear physics and reactor design (this should be rather unsurprising, but for some reason everyone thinks they are qualified on this matter). I suspect you don't meet either qualification, given your comment.
So with the Iran deal, what do we have? Well they would have needed around 3-6mo to enrich their stockpile for enough material for a single weapon. Something they haven't done before and do not have the technology to do. Also something they did not appear to be attempting to do.
But I talked about consensus. I'd say Nature is a good source for that[0]. You'll note here that Nature is talking about getting enough enriched material in months but several other news sources I looked at used the phrase "build a weapon" instead. I'd call this fear mongering and misunderstanding the science.
I'm not trying to tell you that you're dumb, but rather that this is a complicated matter and that amateur levels of understanding aren't quite enough to even get the basics. I have a degree in the field, have worked in the industry and in energy departments. My level of understanding is barely enough to get the basics. I'm calling you out because we're talking about something extremely complicated that people vastly overestimate their expertise to handle. Atomic physics is not a simple thing where you can get a basic understanding through even months of googling.
If a big country like France can handle guarding hundreds of small nuclear weapons, they can certainly handle guarding nuclear fuel in small number of additional NPPs. We are not talking about building NPPs in every small town guarded by incompetent local volunteers. Trained armed personnel and accountability of processes and personnel in few facilities can prevent this risk.
The term you're referring to is capacity factor. Nuclear power typically has the highest capacity factor of any energy source. [1] [2] For reference, nuclear is 92%, while wind is 35% and photovoltaic solar at 25%.
> 2. Spent fuel?
It can be reprocessed, reclaiming over 90% of fuel. Even without reprocessing, nuclear fuel's energy density is such that a tiny amount of waste is produced per unit of energy. For comparison, the sum total of all of the USA's nuclear electricity production occupies a volume the footprint of a football field, and 10 yards high. [3]
> 3. Proliferation risk?
Nuclear fuel is refined to about ~20% fissile material. Nuclear weapons typically need over 80% or 90%. Countries would need to build their own enrichment facilities to bring nuclear fuel to weapons grade uranium, and then further refine that to plutonium. If they had such facilities they'd be able to refine natural uranium to weapons grade anyway.
> 4. Accident mitigation?
First of all, even if you include Chernobyl nuclear power (which didn't even have secondary storage) has the lowest fatalities per unit of energy produced [4]. People often neglect the fact that fossil fuels kill millions each year due to air pollution. Renewables like hydroelectricity have had accidents far more devastating that nuclear power [5]. Nuclear plants are expensive because a lot of effort is made to make them safe, and to contain a potential failure. People often forget that the USA had a reactor meltdown analogous to Chernobyl during the Three Mile Island incident. Except nobody died and there was no widespread contamination because the reactor had a big concrete condom over it, unlike Chernobyl.

I've wondered about that. On one hand, the reasoning above makes sense. On the other, people who know far more than I do say there is proliferation risk. I suspect there is something I don't understand.
I believe it is in the Nuclear Non-Proliferation Treaty or was proposed as another agreement.
Who? I mean I hear people on the news state it, but never any concerns at a certain 3 letter agencies that is not the department of education. I haven't heard a serious nuclear physicist be concerned with the Iran Deal. And when Iran broke the deal (not long ago) those same people knew it was a bluff, because Iran didn't even have the ability to produce enough enriched material to create bombs. Even running their enrichment centers at full capacity. Which btw, these enrichment centers don't scale linearly, which is why it is easy to vet through satellite photography. Weapon enrichment centers are typically kinda obvious. This may be a key part in what you aren't understanding. I also linked in another comment the Megatons to Megawatts program. You'll notice there the conversion rate of weapons material to fuel was about 30x (remember, reversing that process is not linear).
For other people reading: I'm very well read (for an amateur) about the Iran deal, and it appeared to be accepted by experts that they could enough produce weapons-grade materials for a nuclear bomb within around a year. I don't recall anyone questioning it. The goal of the deal was to push the timeline to multiple years (if Iran violated the deal).
The "Cultural Revolution" began in 1966. In such a context an otherwise avoidable catastrophe may happen.
This Revolution followed the "Great Leap Forward" ( https://en.wikipedia.org/wiki/Great_Leap_Forward ), with famines. "In the subsequent famines of the early 1960s popularly attributed to the Great Leap Forward, Henan was one of the hardest hit and millions of lives were lost." Source: https://en.wikipedia.org/wiki/Henan#Modern_Era .
Moreover all this came after a civil war and violent Japanese invasion, during which dams were bombed, causing "massive flooding in Henan" (same source).
In such a context and chain of events a nuclear reactor and its nearby spent fuel may cause some headaches.
Banqiao: predicting and adverting this catastrophe was possible, but given such a context nobody was able to do so.
2 - For the spent fuel, France has plenty of strategically maintained relationships in what used to be West African colonies with uranium mines. Why do you think we sent the army during the Mali war ? We cultivate those alliances because they bring a lot on the table, from resources to routes and bases. Nuclear is doubly interesting for us, because we can source it even if Russia or China decide to tell us to go to hell. In case of a conflict, this is priceless.
3 - I don't know anything about proliferation, so can't answer this one.
4 - Accident mitigation is the big problem, IMO. I've seen how they operate inside, and let's just say I'm glad the people that designed the thing were very, very, _very_ good at their job. Because the ones maintaining it have a very relaxed attitude. And the plants are pushed to produce way past their initial expected life span. But I insist, I'm amazed at how good engineers of the 70' were. Those plants are old tech, but they are incredible. However, even if the probability of an accident is low (there are triple safety mechanisms everywhere), the severity of a potential accident is such that I consider nuclear disasters a huge risk that we don't take seriously enough. What's more, it nourishes the growing anti-nuclear sentiment, so we should really get our act together.
Global warming effects are global, non-linear and there are still many unknowns, which makes it more risky. Nuclear risks are local and the harm is well known. Also nuclear energy is anti-fragile (more disasters means saver plants).
I believe we are far too cautious with building new nuclear plants. Not because I think that nuclear energy is not dangerous, but I believe global warming is a far greater risk.
Nuclear energy should not be our only source of energy for other reasons like resiliance (diversity in sources make a society more robust), power balance (you don't want one type of industry to have it all) and long term cost opportunity (some energy may prove cheaper later if we also develop them).
And since we are using nuclear energy, we engage in this risk, which we should mitigate given the magnitude of it. Ignoring it is not rational.
Opposing the risk of a nuclear accident to globalm warming is a false dichotomie. Like stating we don't spend money on fighting covid because cancer is more deadly, more likely, and need all the money we have.
Of course we should not ignore the risks of nuclear. But my point is that there is no 100% guarantee that no accidents will ever happen. But considering the problems we are facing, the risk characteristics of nuclear are favourable to the problem we are solving.
After all, climate change kills a lot of people, we only have to kill less.
But the problem here is that climate change is not shocking to people. But a nuclear accident would be. In fact, 2 of the 3 nuclear disasters we had are burnt in the collective memory for ever.
So strong action to prevent such accidents are also needed as a communication measure, to reasure the population. Given you are "anti-anti-nuclear", I think it's a good step to reduce the "anti-nuclear" sentiment.
Should we tell the public simple messages like: "Trust me dude, it is super super super safe!", or should we tell the public a nuanced story of calculated risks? I don't know whether the last strategy will work, but the first strategy has failed both nuclear and COVID vaccination. In my country we are in a lock down again, because too few people are vaccinated.
2. Solved problem. Spent fuel is not really an issue, we have solutions and areas to put it in both Europe and the USA. Only green Luddites hold it back. Storage really does not take up a lot of space.
3. Next to none if the right type of fuel stock and reactor is chosen. Obviously security comes in, but that is also a solved issue
4. Lots of modern designs literally cannot go critical, I suggest we use those, instead of old designs just because they're "a known known".
5. don't build reactors that can go critical near known tsunami shorlines.
6. At worst we'll surely have fusion by the end of the century and can then retire the nuclear plants. Solar and wind without a 100x improvement in battery storage tech do not make sense right now as the sole producer of energy like a lot of unrealistic "environmental" groups claim.
If not, I hope France seriously considers using breeder reactors to reduce leftover radioactive material.
Otherwise, I think this is fantastic news. In fact even if they build light water reactors I think it is the ideal base load solution to bridge the gap from oil and coal.

After Superphenix I don't think they are in any hurry to develop the LMFBR.
(Answering again as the previous answer was attached to the wrong parent when the articles were merged)
In France: ASTRID burnt ~700 millions euros and didn't get past plans. Before it the 'Superphenix' project burnt ~8 billions euros, was built, had a long chain of incidents, then was canceled. Before it the 'Phenix' project ran then had serious problems ( https://en.wikipedia.org/wiki/Superph%C3%A9nix#Earlier_work_... ). Before it the 'Rapsodie' project also ended with problems.
Notwithstanding numerous projects in other nations. Nowadays Russia (and India, to an extent) is the only nation pursuing this path.
EBR II and FFTF operated with no major problems in the US, but the Clinch River project was canceled. However the US has failed to construct a mixed-oxide fuel facility which is the most developed fuel for a fast reactor (e.g. pure metal and nitrides are both options but oxide fuels seem to require a high energy ball mill that can turn harmless silica into deadly nanoparticles that can wreck your lungs, just imagine what it does with Pu)
MONJU burned up in Japan.
The Russians have documented hundreds of sodium fires in the BN-350 and BN-400 but they would say fires happen in industrial facilities all the time and people just put them out. They turned on the BN-800 in 2016 and it is now consuming nuclear weapons plutonium.
Old literature suggests that the capital cost of the LMFBR is inevitably worse than the LWR. I'm not sure that's right. Both the LWR and coal burning power plants have been uncompetitive since 1980 against gas turbines for power generation. A closed-cycle gas turbine would fit in the employee break room of the turbine house of a nuclear reactor, but it is an undeveloped technology. A high temperature reactor with a gas turbine powerset could potentially be an order of magnitude smaller than an LWR, not have high pressures, have no risk of a steam explosion -- I think next generation nuclear is not worth pursuing unless the capital cost can be brought radically down with those factors.
There is a precedent for commercial licensing of the LMFBR in the US. Terrestrial Energy (Bill Gates's company) is making noises about building one but they are holding their cards so close to their chest that it's hard to believe they have a realistic plan to do it.
Oxide fuel technology is of course pretty mature, as that's what current generation LWR's all use. However, it has severe disadvantages in a LMFBR. US thinking was apparently that they would jump straight to metal fuel (EBR-II and the canceled IFR), other who have used it see it as a stopgap until nitride fuels become available (e.g. Russia is experimenting with nitrides in their fast reactors).
As for economics, technically breeding is extremely cool (catnip for physicists!), but with current uranium prices there's no particular economic driver to develop and commercialize the technology. I think it's very hard to compare prices for mature LWR technology and various one-off fast breeder prototypes, let alone paper reactors. It's useful as a backstop for rising uranium prices, however.
> There is a precedent for commercial licensing of the LMFBR in the US. Terrestrial Energy (Bill Gates's company) is making noises about building one but they are holding their cards so close to their chest that it's hard to believe they have a realistic plan to do it.
The Bill Gates backed company is Terrapower. They have some agreement with GE Hitachi to develop and commercialize the technology, called "Natrium". AFAIU the Natrium reactor is heavily inspired by the canceled IFR, using metal fuel. We'll see what happens, interesting tech though.
(Terrestrial Energy is the company behind the "IMSR" molten salt reactor. It's a thermal spectrum uranium burning, non-breeding reactor design, though)
But uranium oxide vs mixed (plutonium) oxide fuel (used in LMFBR) is a big difference. The later is made by making plutonium nano particles that are potentially deadly for workers in the factory.
France doesn’t get excited about it but the US doesn’t seem to think it can be done safely.
France is one of the few countries that do recycle spent fuel. https://www.iaea.org/newscenter/news/frances-efficiency-in-t...
France is a nuclear capable country, so the proliferation risk is fairly low from what I understand. They could even sell the plants abroad and bring the waste back to France to be recycled.
Germany is not a nuclear capable country, and I am not sure how they feel about France being their primary source of energy (or enriched uranium, if they have their own plants). Hopefully they prefer French nuclear energy to Russian oil and gas.
Considering europe has a harmonized energy market[0][1], does that really matter?
France, germany and the benelux are so tightly economically integrated anyways, that doing harm to one would result in massive chaos in the others.

Germany never had a substantial nuclear deployment. It peaked around 20GW. About 8 remains. The disappearance of 16GW from the grid was a complete non event. No blackouts. No instability. It just happened gradually and now its gone. The remaining 8 are tiny compared to daily fluctuations in wind and solar that are also not an issue. In terms of base load it is completely irrelevant whether it stays or goes. It's certainly not worth paying a lot for. If you replace 20GW with a few hundred GW of wind and solar, you end up with plenty of capacity and baseload. That's more or less what happened in the last few decades. The French already import excess power from Germany and elsewhere below the price they are selling their own nuclear power quite often.
Nuclear never mattered in Germany other than for military strategic reasons that stopped being relevant when Russia withdrew their tanks from the DDR 30 years ago. All that remains is cold war era obsolete plants that are expensive to keep going. Shutting them down was going to happen no matter what (because they are obsolete and near end of life) and the decision to not build replacement plants was pretty much a constant. The debate around that was pretty much over before Fukushima already. All that did was fast track some of the decision making. It remains a popular and uncontroversial decision in Germany.
Macron is announcing intentions and plans in the middle of an election season where Macron is under a lot of pressure from right wing populist parties. This nuclear push is very much motivated by nationalist sentiments and Macron is in damage control mode as he's losing voters to several right wing parties; some of which you might classify as far right or even neo fascist.
We'll see what remains of those intentions and plans after the elections. Election time posturing is not to be confused with actually policy to spend many billions on nuclear. Assuming he actually wins, he might find himself once more forming a government with a few other parties that will have strong opinions on this topic and not a lot of budget to allocate to a wide range of topics competing for attention. Until that government is a reality, all you have is a politician trying to stay in power trying to appeal to voters currently entertaining the thought to vote for someone else. Even with these announcements, we're still talking a net decline in nuclear capacity over time. It's just slowing it down slightly.
Personally, I think it is wise for the French to keep the knowledge to build reactors going for another generation. Additionally, exporting that knowledge to e.g. the UK is good for their economy. Hinkley Point C is being built by French EDF. Of course, there are plenty of scandals surrounding that particular setup related to cost overruns, delays, etc. That seems to be a constant with nuclear. One thing is certain, it won't be cheap power. Gas is cheaper, even with the recent price increases. Saving money is not a reason to go nuclear. It never was. Whether the UK ends up buying more is very much up in the air. The drama around Hinkley Point C is probably not helping the nuclear case currently. And having to send the money to France is probably not helping that case.
There was ASTRID, another sodium cooled fast reactor design, that was cancelled a couple of years ago before it got off the drawing board.
I know there are cases of decommissioning too early, or even a reactor that was fully built but not even started operation (I think Tom Scott had a video on that?), but I don't think that's the common case.
There was also a scandal a few years ago when the state-owned nuclear construction company Areva acquired Le Creusot Forge. It turned out that there had been a decades long coverup of weaknesses in the steel forged there for nuclears plants, and falsification of documents.
The problem here isn't "political will".
See: https://en.wikipedia.org/wiki/Flamanville_Nuclear_Power_Plan...
thorium won't last much more, and it's not even viable at this point, this seems like a desperate attempt to maintain the power consumption per capita for some more years before the inevitable collapse.
Flamanville has been super disappointing however in France.
Russia will provide them all the energy they need, and the US will provide them defense against Russia. Perfect!
- edit -
Is it still morally sound if you outsource the immorality elsewhere?
But now, with the carbon tax and gas prices in EU, I wonder if Russian mfg capacity will suddently become competitive.
The funniest thing would be Europe pricing itself out of Russian oil due to carbon tax, and then buying now-cheap goods from Russia made based on affordable oil.
If that's what it takes to be morally sound - then bring it on destiny, I say, bring it on!
Edit: This a German's attempt at sarcasm, please indugle me!
I get German Greens have a very specific agenda for historical reasons, but sheesh.
[0] https://en.m.wikipedia.org/wiki/Cutting_off_one%27s_nose_to_...
Germany has been ruled by the CDU for the last 16 years so I'm not sure what exactly the Greens have to do with the current energy policies of Germany?
And I'd assume that as the center, courting interests important to their voters is of outsized importance to the larger parties, in an attempt to peel off votes?
But maybe I'm poorly informed?
You're right though that before the final Merkel administration the Greens, the CDU/CSU and the FDP had talks, which ultimately failed because the FDP passed the CSU (the right-wing regional appendix to the CDU) on the right, which was a bit too much for the Greens, which at the time largely occupied the same center-ish position they hold today, having shifted right considerably in the time between 2005 and 2017.
Overall the impact of the Greens party has been very small on the Merkel administrations, however, some parts of the green movement (which is not closely tied to the Greens party) in Germany are the majority opinion in Germany (especially when it comes to a heavy anti nuclear stance) and that's sufficient to drive Merkel policy making. It's also important to note here that Germany has a very strong NIMBY attitude, so while the majority "wants" green energy, they don't want any of the infrastructure in sight.
I'd also like to point out a fundamental difference between Bundestag culture and US Capitol culture. There are bi-partisan bills in the Capitol, but in the Bundestag it is customary for the ruling parties to unconditionally veto drafts introduced by other parties - exceptions are rare. Almost all votes in the Bundestag are under Fraktionszwang i.e. MPs deviating from the party line won't get on the election list next time around, so don't have a safe seat any more (because parties in Germany can't literally force their MPs to vote their way, they can only "incentivize" it).
I'm in the middle of Dark on Netflix, and even as a single perspective it's felt enlightening in how it poses the German everyman in relation to the nuclear energy industry. In a way that feels very different to even US perspectives (my country).
In your opinion, would it be fair to say that Chernobyl and then the Cold War drumbeat of nuclear weapons use were the main historical anti-nuclear motivators? And then Fukushima stirred up that present-but-latent thinking in the modern zeitgeist?
I guess the nuance I'm most interested but confused about is how Fukushima triggered such an apparent breakdown in nuclear support in the center-right, and so quickly? Was there pre-existing anti-nuclear sentiment there too? Or was it more about pro-coal sentiment? Or something else entirely?
Politically, things have become far more convoluted in recent years with large parts of the green spectrum becoming more and more critical of "radiation" in particular (cellular networks, wifi, microwaves, anything nuclear) and entire branches of science in general (nuclear research, obviously, but also pharmaceutics, medicine, biology and others).
As far as the Green party is concerned, historically it had two wings ("fundis" and "realos", the former being the fundamentalists, the latter being realpolitikers), which in principle would both count as sort of left, but in practice the fundis stayed more or less left-ish, while the realos migrated to the right. The SPD-Greens coalition was enabled by the realos wing. Similarly, the realos are now the de-facto ruling wing inside the party since 2018, which is why a SPD-Greens-FDP coalition is possible in the first place.
Coal is quite a difficult topic. Most coal is strip-mined in Germany, which causes the expropriation of entire villages and small cities. That's not a talking point in politics. A state PM illegally dissolving protests against strip mining isn't even a scandal. However, if for example The Left publicly ponders whether expropriation of apartment houses and conversion to social housing in cities could be one way to solve the housing crisis, that's a major scandal and causes them to not pass the 5 % threshold. That might give you a feel for the standing of coal. Despite only employing around 20-25k people in Germany, maintaining coal jobs has become basically an iron curtain protecting coal.
To circle back to the Green party, it's noteworthy that their party program is not even close to a program in line with the 1.5 °C target.
As the quip goes in the US, 'The left is a big tent party (accepts all sorts) and so is constantly debating itself. Whereas the right expects everyone to fall in line with the party platform.' But recent presidencies challenged the truth of that.
Coal serves similarly here, for a single reason: votes in Illinois, Pennsylvania, Kentucky, and West Virginia. Were those not necessary states to forge a path the presidency, no one would care about the topic. But since they are, even negative statements about coal are couched in very careful language.
IMHO, it's actually more about the ideal of a "coal miner" than it is about actual coal mining. Most of the people supporting it will never work a day in a mine: and nor will many others, with the amount of automation these days. But why let facts get in the way of a good political story? :)
I was happy to see the UK's push at COP26 for annual subsequent meetings to examine and refine nationally determined contributions [0]. Hopefully that will put some "Words are cheap, but we don't actually intend to follow through" countries under more scrutiny.
You mean they aren't any more?!?
No, not being sarcastic: international news media hasn't reported on that, or if they did, I missed it. So where are they now -- center-left, center-center, center-right...? And by how much? (I doubt they've gone far-right, right?)
That’s usually not true fwiw, germany tends to export when nobody needs the electricity e.g. fair weather with high winds, especially week-ends.
And it’s not so much exporting as dumping, german electricity prices regularly go negative because winds crush the grid and they need to shift it so they don’t melt.
The “collaborative” aspect is that france has a large and resilient grid well connected to less provisioned southern neighbors (wholesale prices in spain and italy tend to be quite high), so they can arbitrate and profit some.
But they also must, because continental europe is a synchronous grid so if germany melts down it fucks up the entire continent.
1. Coal,
2. Renewables (Solar, wind, perhaps ocean currents),
3. imported oil.
Coal should be deprecated already. Renewables are dependent on environmental effects, in particular solar doesn't work in emergency situations such as volcano eruptions rendering the sky dark. For oil, we depend on third parties, of which we know that they do not have our best interests at heart.
It is depressing to see the political situations on these metrics, especially the idea which gets pushed now, which claims that everything will be alright if we just optimize our energy consumption. It ain't gonna happen. People won't meaningfully reduce their energy-consumption, at least not in a way that would justify the use of fossil fuels.
So what are we left with? Nuclear is the only good bet you could make right now, while waiting out on fusion.
edit: I often think of this meme which goes around, talking about the fact that people are much more willing to donate to a single child in need, rather than a group of children who equally need help. People are prone to take action when they feel like their individual action makes an impact.
I feel like this is similar to the fossil fuels - vs - nuclear debate. We know, that about 20mil ppl die every single year due to air pollution. We also know, that a very small, countable number of people died of nuclear accidents, in the complete history of humanity, ever, in total.
Yet we seem to think that the few nuclear accident's fatalities are worse than the ones caused by air pollution. Why? Because we are in some way biased to give more meaning to individual events, rather than rates of change that are around us. And it'll break our backs if we don't carefully examine the problem at hand.
I'm not familiar with this. Is this a common problem in Germany? Are southern states like Baden-Württemberg more afflicted or less compared to more northern ones like Schleswig-Holstein?
https://electrek.co/2021/09/27/the-worlds-longest-subsea-cab...
The problem for doing this large scale if the right of way for the HVDC lines. I'm watching this on a smaller scale in Massachusetts, where Maine voters are blocking a HVDC link to Hydro Quebec. But I think this is a game between established interests.. in this case NextEra funded the ballot question and advertising, I think because they lost out on their SeaLink project (HVDC to Seabrook nuclear power plant).

Actually not as bad as I thought it would be!
Germanys relationship with Nuclear power had been one with Tons of absurdity from the get to go. To name a few examples (in no specific order):
- When West Germany decided where they should (temporary) store nuclear waste they had a list of potential abandon mines. While this list wasn't quite up to modern standards it was well thought out. But in the end they choose a mine which not only wasn't on the list, but was known to not be well suited. Reason: Pettiness, east Germany had just done so too, so they choose a mine at the border to east Germany.
- The Anti-Nuclear Power movement in West Germany was partially sponsored and instigated by East Germany (through so where most non-small movements).
- after Fukushima plans to stop using Nuclear Power where moved up costing the State millions due to existing contracts and being questionable. I mean the danger of Atom power had been well understood at that point in question, Fukushima didn't change this, nor did it unearth any (not already well known) huge flaws. So this asks the question if it is so important why wasn't it started years earlier, if it isn't why move so abrupt?
- Germany loves importing nuclear power, not only from France but also from other countries with lower safety standards of which the reactors aren't that far of Germany (geologically seen).
The phase-out was announced in 2000 and started https://en.wikipedia.org/wiki/Nuclear_power_phase-out#German... and was effective: https://en.wikipedia.org/wiki/Nuclear_power_phase-out#/media...
> Germany loves importing nuclear power
Each and every nation connected to the European supergrid imports when needed and exports when possible, because it is much more efficient than trying hard to maintain autonomy. The is eases balancing production (which may originate from anywhere) with consumption.
Here Germany often acts as a provider for Poland, Austria, the Czech Republic and Switzerland (which also may provide it to other needing nations).
Germany export surplus (physical flows) is positive for years, albeit it decreased (from 34 to 18 TWh in 2020). Source: https://www.ise.fraunhofer.de/en/press-media/news/2020/publi...
> 1. Coal
Yes, from Poland
> 2. Renewables
Yes, definetly
> Solar
Already plans underway to force every new home to have solar panels on its roof, regardless of the direction of the gabel and regardless how non-significant solar energy is in Germany anyways. Existing home-owners love the idea of increasing construction costs for future home-owners...
> Wind
Already plans underway to massively increase density of windmills per km, regardless that the existing mills already are turned off for most of the year (because it would melt the grid to keep them running), regardless that we're chopping down huge amounts of trees to make room for them, regardless of the environmental impact of planting unremovable kilo-tons of concrete footing into the ground
> Ocean Currents
No, for two reasons. One: Maintenance costs make this technology inefficient (rust). Two: Since we're world champions in moral soundness our whole tidal-range-gifted coastline is deemed a national park and as such is forever excluded from any such infrastructure work
> 3. imported oil
Already doing that.
I fear, unless there is some crucial pain of whatever sorts on behalf of the average German, our nomenclatura will continue to proceed with the current polciy of "nearshoring responsibility". Because:
> It ain't gonna happen. People won't meaningfully reduce their energy-consumption
German consumers still don't do that, despite paying the highest electricity bills in the developed world (almost twice of what the French pay). Apparently we can still afford to kick down the can (or rather to kick it across the border).
No (France .32, Germany .19), and this comparison isn't sound because the financial models differ: Germany finances its transition by taxes on energy, and France mainly finances it thanks to other taxes (the consolidated tax burden is way higher in France).
Prices: https://ec.europa.eu/eurostat/statistics-explained/index.php...
Moreover higher prices are a way to moderate consumption and entice energy-saving approaches.
.32 is in my book far from "almost 2 times" .19
> Germans already are having the highest income-tax and social-security costs of the developed world
Nope, the tax burden is way higher in France: 46.2% of GDP in 2020, while Germany is at 37.5%

False, once more. France is clearly way ahead of Germany, and for quite a long time (and until now I thought it is well-known): https://en.wikipedia.org/wiki/List_of_countries_by_social_we...
Having lived in a couple of Nordic countries for most[1] of my life, allow me to be sceptical about that.

I have a question around waste management though: Do we know if there are big improvements here? IOW - https://apnews.com/article/washington-business-nuclear-waste... bothers me.
Assuming they really set this project in motion, there's plenty of time for the next government to cancel it.
https://www.google.com/search?q=epr+emergency+feedwater+syst...
I guess they have to build with the tech they have, but it would be nice if they'd spent the last few decades researching better designs.
Injuries and death are sadly a part of life at all large industrial plants.
Based on first principles, nuclear is the cheapest. Its historical path dependency that it isn't.
Fission breeder reactors have the potential to use the least amount of land, be the safest form of energy, have the lowest cost of fuel (essentially free)and use the least amount of total resources (steel, concrete and so on).
These could be used for all kinds of applications, including creating of medical isotopes, nuclear batteries, industrial heat and power.
Non if this is new, these insights are from the 70s and in 50-100 years people will look back and ask 'why were these people don't doing it? They had all the technology, it makes no sense'.
France were about to build new nuclear energy reactors anyways. They had a 5-8 new plants in planning for this decade.
Are you talking about the sale of its power sector to GE in 2014? It is mostly about turbines, not the nuclear aspect, which is more typically under the expertise of Areva NC / Orano Cycle <https://www.orano.group/en>.
Turbines used in nuclear power plants as well as nuclear ships. That sale was/is a major scandal in France.
I’ve worked on steam turbine before that had boiler fed from bio-fuel or kerosene.
Is the turbine itself not just a shaft with a series of blades, an inlet and an outlet?
Any specifics you can get in to would be very interesting to me! Thanks
At least we'll have a debate topic during next year election cycle that is not immigration or Islam - that will be a change.
The job of the nuclear security agency will be tricky next year : they'll have to double their effort ("The President does not want an accident making the news") but also stay quieter than usual ("The President does not want any kind of small incident making the news".)
They're independant in theory, of course, and they want to do their job well, but they have biases and bosses who have bosses, etc... I doubt they'll let anything big slip just for électoral purpose, but the scrutiny on their job (especially from the left wing press) will be interesting to see...
[EDIT] For that matter, we all did the same stuff in ascii for years. Asterisks for emphasis (bold, now, in many places), underscores for underlining (which, in the case of, say, book titles, is better represented as italics if you can print italics instead, so I'd guess that's where the "underscore = italic" thing comes from)
As usual ramping it up implies to build one (the 'tête de série') or at max a few ones, then to launch series. We always did it this way.
Since 2005 4 projects were launched (France: Flamanville, Finland: Olkiluoto, China: Taishan, UK: Hinkley Point). The two first ones are ongoing disasters. Taishan was late and overbudget. Hinkley Point announced, 2 years into its launch, that it will be overschedule and overbudget.
In such a context launching now a huge amount of projects isn't realistic. When a project is late due to a lack of skills and project-management abilities (there is a report about this, the "rapport Folz"), launching 6 new projects may not be a terrific idea.
The source is a Bloomberg article ( https://www.bloomberg.com/news/features/2021-11-02/china-cli... ) which states that the boss of Chine General Power corp. announced his plans 200GW for 2035, nothing more. Admitting that it is an official governmental announcement (it doesn't seem so(?)) and given that China already has 50GW, that's maybe 100GW new (way less than 150 standard reactors).
Compare with renewables: 790GW already running (26% of the gridpower), and 1200GW planned for 2030. In 2020 China added 71,6GW windturbine power. Even considering the load factors the picture is pretty clear.

Same from people all over europe who for decades pushed down France for its Nuclear efforts
Now that the US is working toward catching up, they all voice they pro-"US"-nuclear
It's very sad, europe is full of cowards
But yet again China ahead of everyone else because they are free from these little "marketshare" fights
EPR was designed by followers of Amory Lovins that wanted to make a reactor which is unconstructable at any cost and schedule.
They tried building an EPR in Finland and it is a decade behind schedule and nobody cares because the people working on it have the best paying job they ever had.
They did get an EPR running in China but had fuel damage right away.
AP1000 is running in China for real and will be running at Vogtle in Georgia USA next year. There have been so many ownership changes that I would have said AP1000 was a Japanese design 10 years ago, now it is effectively a Chinese design.
