> NuScale Power (SMR.N) said on Wednesday it has agreed with a power group in Utah to terminate the company's small modular reactor project, dealing a blow to U.S. ambitions for a wave of nuclear energy to fight climate change and sending NuScale's shares down 20%.

The SMRs' _only_ advantage was the relative ease of construction. Only a handful of companies in the _world_ can construct reactor vessels for large-scale PWRs, and none of these companies are in the US. SMRs can be constructed domestically.
I was surprised they even had that, but they do have nuclear powered ice breakers, so I guess it makes sense.
It makes sense as a portable power plant for emergencies, or for remote military/mining outposts where economics are different.
I'd love to see expanded nuclear, but if that requires corruption it's a tough pill for me.
Maybe China will finally deliver some cheap reactors to work with, although I assume they are running into the same problems that we did (and corruption is a bit problematic with nuclear power plants).
I wonder why this might be? Just a quirk of where the highways run?
Interestingly Illinois actually doesn't have a very large coastline. Would it be sufficient for off shore wind? I guess it is convenient that Chicago is right on the lake, and the city must represent a huge percentage of Illinois power consumption.
Yes, most likely. According to this site [1][2][3], Illinois has almost double the wind generation capacity of Indiana. The average megawatts per site is almost 50% higher. Neither state holds a candle to Iowa, but again with Iowa most of those turbines aren't visible from an interstate.
EDIT - This wikipedia page [4] shows a list of large wind farms in the US. Sort it by capacity, and you'll see that the turbines you see on I-65 in Indiana are part of two adjacent farms that each are in the top 15 largest in the US and would be the second largest in the US if considered a single project.

They're only economically inefficient when you ignore the costs of burning fossil fuels. Would you rather spend a couple (tens of) billion on a nuclear power plant, or face global starvation?
Everything looks expensive when you externalize the cost of status quo.
Nuclear do like their subsidies in term of research, building, deconstruction and waste storage. However looking at Europe, around 70% of that is for the single fusion research project called ITER, and like supercolliders, its not exactly about producing a product for paying consumers.
Wind/Solar are the single biggest recipient of subsidies in EU by a factor of 2x of everything else in the grid. They also get far more per watt produced than anything else, mostly going to building, deconstruction, grid connections and price guaranties.
Hydro receive a lot of subsidies for repair and modernization. Dam repair and flooding protection is expensive and with climate change there is even bigger need for fixing Europe old hydro power dams. They are also in general non-compliant with the environmental regulations (several species are going extinct), but that is not a subsidies issues directly. Fixing the dams so they allow for fish to pass is however a subsidies issue, but as far as I know no country in EU has so far started to put any serious money into it.
And then we have fossil fuel subsidies. A large portion of the "reserve energy" plan in eu (the one that is used to balance the grid) is based on keeping a large number of fossil fuel plants on stand-by, paid through subsidies. Then there is subsidies on extracting the fuel itself, subsidies on trading fuel, and subsidies on storage of the fuel, and transportation of the fuel. This is not accounting for the environmental cost from burning fossil fuels, which some see as a form of subsidies.
Energy subsidies are quite frankly very corrupt in basically every part that there is.
Well, that's what you have a national grid for. China for example has links that go way more than 2.000km - that's more than enough distance to transfer power in times of low wind or whatever around.
From EE101: P=V * I. But power transmission losses are I^2 * R.
So one way to transmit large amounts of power with low losses is to, well, turn the voltage up and use a lower current.
And with lower current, you can use smaller cables.
And in fact, that's what we do.
That's why your power lines to your house are thousands of volts and the transformer hanging on the pole will convert it into 220V (but with higher current to run your hair dryer, say).
Read up about Hydro Quebec. They generate gigawatts in Northern Quebec and export large amounts to New England. HVDC is pretty efficient.

If you draw the map of lines with proportional thickness for various voltage levels it looks vaguely fractal, like an old tree.

The article talks a lot about carbon-free electricity by 2045, but I see nothing about where the SMR's might be manufactured. Between the Mississippi River and St. Lawrence Seaway - SMR's could easily be brought in from ~anywhere on earth.
Anything that we build in the future must be walk-away safe, a Gen4 reactor or better. There can't be any question of exploding cooling ponds or other surprises with (design) flaws in safety systems. This obviously rules out diesel generators in the basement.
Over the years, there have been nagging stories of drones that overfly reactors. We have no idea who is collecting this data or what they want with it. We have to reach much higher safety standards than the elderly fleet of reactors that remains with us.

36 hours. That's all it takes.
At the moment, barring magical energy sources that haven't been proven in any meaningful sense, nuclear technology has shown itself to have the fewest long-term consequences and the highest efficiency. However, it is unfortunately also the easiest to point to a few events in history and easily make the layman cast doubt on its safety. It's worth pointing out that the most significant nuclear accident in history took place in the USSR (which wasn't particularly notorious for its safety protocols), on a reactor that had several known design flaws that were ignored, and the only other major accident representing a one in a thousand years perfect-storm that overcame several redundancies.
This concern about "drones" in relation to nuclear power plants is borderline paranoia. Are you concerned about drones dropping bombs or somehow disabling safety systems on a nuclear reactor? Every single nuclear power in the world has nuclear power plants, so they're all equally susceptible to the same attack in the same way that they're all equally capable of responding to said attack- mutually assured destruction as it goes.
A lot of the world's living population lived through Chernobyl, the various incidents at Sellafield and then Fukushima. All events that "statistically" should not have happened nearly as close together as they did - and that's without taking the risk of 9/11-style terrorism, actual acts of war (see Zaporizhzhia NPP) or catastrophic earthquakes into account.
There are only two kinds of power generation that have a mass-casualty potential: nuclear power plants and dammed hydro power (as evidenced by what went on at Kakhovka Dam). We should, as a species, get rid of these. The sooner, the better.

Fly a plane into an NPP and you're looking at a massive contamination issue.
Hell, I live in Bavaria, and to this day you have to inspect shrooms and wild game meat for radiation - and it's likely to exceed safety thresholds, even decades after Chernobyl.

The people at the Nova music festival in Israel would have said exactly the same thing as you in the hours before the event.
Black Swans can and do appear.
In contrast, a single coal plant in Illinois, Prairie State, kills about 75 people every year with coal soot: https://www.sierraclub.org/illinois/blog/2023/02/prairie-sta...
For coal plants, murder is business as usual. That's why we need nuclear power.
We need to stop burning fossil fuels, but nuclear is simply too expensive compared to renewables.
Fuel rods from reactors near me are discarded after only 2% of the potential power is released from them. I understand that the best designs can extract 40%, leaving less waste. New reactors should be held to a minimum of 20%.
The "daughter nuclei" in the 2% exhausted fuel rods require active cooling (circulating water) for well over a year before they exhaust and cool sufficiently for dry storage. We need "walk-away safe" designs where a complete loss of power doesn't result in catastrophic explosions.
We have kept this 50s technology way past its design life. It isn't replaced because of resistance to building any more nuclear at all, which is not helping.
Until the cost problem is solved, nuclear power is dead on arrival. The existing plants were only built because of massive subsidies and the government placing a cap on the maximum liability from nuclear accidents.
Burning fossil fuels is too expensive.
