So yes, nuclear waste is a serious issue, but let's not forget that the alternatives have major environmental costs as well.

So yes, nuclear waste is a serious issue, but let's not forget that the alternatives have major environmental costs as well.
(not from the US)
1. Nuclear waste, even when not processed, is not that large in volume and it can be stored in a space on the order of a hectare (about 2.5 acres) for the entire US nuclear waste production over several decades. Consider the comparative amount of storage needed for just coal ash, as well as the environmental hazards that presents.
2. The reason the US does have comparatively more waste is because the government forbids any reprocessing of nuclear fuel. For example, merely separating out the more radioactive isotopes, you can greatly reduce the volume. Reprocessed fuel can also be partially reused in a nuclear reactor and the French have great experience with that.
3. Even reprocessed "spent" fuel can be useful in 3rd and 4th generation reactors. Spent fuel today is still a valuable future resource, so it needn't be buried and guarded for millennia afterwards.
4. Natural nuclear fuel usage can be greatly more effective with nuclear breeding, which can turn non-fissile U-238 and Th-232 into the fissile U-235 and U-233 respectively. Right now, what's actually burned is mainly U-235, an extremely rare isotope (the minor constituent of "natural uranium") and that's comparatively as rare and expensive as platinum. Breeding can increase the energy obtained from the same quantity of fuel by 10-100 times.
To me the main problem with nuclear energy is not the waste, which even if we never intend to recycle is such a tiny volume that being afraid of it is like an elephant being afraid of a mosquito. The problem is rather the chernobyl/Fukushima risk.
I am not a specialist but I understand that switching to Thorium could reduce a lot that risk. Most nuclear reactors around the world have been built in the 60s/70s. I would expect that if we decide to replace them, there would be a sufficient critical mass to justify the cost of moving away from uranium.
The risk from these types of accidents is less than the toll from fossil fuels in normal operation.

For Fukushima: ".. no confirmed casualties from radiation exposure.." "no evidence to support the idea.. will lead to an increase in cancer rates or birth defects".
But yes, more modern reactors would be better, but these aren't being built.
Take into consideration that 2 nuclear bombs dropped on Japan did not cause Japan to not exist afterwards. In fact, the damage and death toll from those two bombs was less than from the wholly conventional Tokyo firestorm.
Yes, nuclear technology is a big lever, and yes, big levers are dangerous. But it's simply not as earth-shatteringly more dangerous as people believe.
Remember that there have been no deaths so far from the Fukushima meltdown, which was about as bad as you can imagine, with bad siting, bad technology, bad safety precautions, awful handling etc. At the same time, the Tsunami that caused the meltdown did cause over 15000 deaths.
Again, I think you've reached the right conclusion, but looking at the lack of long-term damage from the bombs doesn't tell us anything either way about the potential for damage from a reactor.
1) I wrote "take into consideration". That means that this is something to consider, not something that proves my thesis conclusively. So your criticism is misplaced.
2) You also miss the fact that bombs are designed to cause as much damage as possible, whereas reactors are designed to contain damage as much as possible. A candle contains much more energy than a stick of dynamite, yet the former is far more damaging.
See https://en.wikipedia.org/wiki/Comparison_of_Chernobyl_and_ot...
Referencing: http://www.iaea.org/inis/collection/NCLCollectionStore/_Publ...
Compare the section: "Chernobyl compared with an atomic bomb".
But what do the IAEA and the WHO know about anything?
First, they show conclusively that "amount of radioactive material" is not the be-all/end-all measurement that you make it out to be. Nuclear tests put a total of 100-1000 times the nuclear material of Chernobyl into the atmosphere, and yet we are also still here.
> It makes no sense to "take into consideration" [..]
Furthermore, they do exactly what you claim "makes no sense". They "take into consideration" the effects of the bombs, and they compare those effects. They do come to the conclusion that the effects are different, one factor being that Chernobyl had more material, a counter-effect being that the radiation from Chernobyl is much more low-level and thus much less harmful (in fact, there are indications that low-level radiation may be beneficial).
But "into consideration" they certainly take. QED.
That kind of stuff is why we need to get rid of nuclear power altogether. All that's holding us back is politicians and their bribes.. and of course, to a lesser extent, people who rationalize not moving away from nuclear power.
Fukushima was a standard design. Built by European and US companies in the same style as dozens of plants in Germany.
This is not "Fukushima was unsafe". If you say "Fukushima was unsafe", then half of Germany’s reactors are unsafe.
Shutting them down was the only option.
> making a few permanent wildlife reserves in the irradiated areas isn't a global catastrophe
You are talking about Japan. A country with one of the highest population densities worldwide. Declaring a whole province – and one with lots of history – off-limits is not going to happen. Currently they’ve been digging out the ground in half of the province.

EDIT: Some more info:
Fukushima was a Boiling Water Generator built by General Electrics. Reactors of the exact same design are Krümmel (Germany), Brunsbüttel (Germany), Philippsburg (Germany), Isar (Germany). Krümmel and Brunsbüttel had constant issues, including the town next to it having the highest cancer rate on the planet.
The same design used by Fukushima is described in Wikipedia as "the second most common type of electricity-generating nuclear reactor".

> Fukushima was a standard design.
The design was unsafe. The company knew this. In fact it had been known for 35 years. It was not unfixably unsafe, and in fact 5 of the 10 reactors had been upgraded. These 5 shut down properly during the Tsunami and survived without problems.

The main design flaw was that the vital emergency cooling equipment was sited in an unprotected building outside the protected reactor. This is especially troubling if you site your reactor on a Tsunami-ridden coast. It's less of a problem in the middle of Germany, where there are no Tsunamis. Or to put it another way: if you have a Tsunami reaching the middle of Germany, a meltdown at these powerplants is going to be among the least of your problems.
Of course, it is hard to demonstrate improvements, especially when nuclear power is so demonized.
It doesn't make sense to say it's hard to demonstrate improvements when it's not even under our control.
But demonizing nuclear power has nothing to do with it.
Gee, what a great idea! In fact, a slightly improved reactor was operating in the other Fukushima plant, and all its reactors were shut down safely after being hit by the same Tsunami.
More modern designs are safer still. For example, there are designs that do not require external power for a shutdown at all.
No, unfortunately, that's not all that's holding us back. There are still some pretty substantial, e.g., storage and transmission problems with the renewables.
Unless you want us to keep burning coal or some other nonsense like that...
Build power lines from everywhere to everywhere, and refit transformer stations to be up to the load of users producing more than using, and you fix that, too. (Incidentally, in Germany we’re having a huge debate about a huge powerline currently, NIMBY is one of the worst things that happened)
You do realize that the largest ever energy-generation accident was a dam failure? 171000 people killed in 1975 when a dam in China failed. And overall, hydroelectric facilities claim 94% of the fatalities of energy-production accidents.
What I am talking about is hydro-pump-storage.
That type of storage has no dam that could fail – you take two lakes, one higher than the other, connect them with a tunnel, and place a turbine in the tunnel. Now you can push the water up (store energy) or let it flow down (produce energy).
However, it is simply not true that hydro-pump storage never has a dam.
See: https://en.wikipedia.org/wiki/Pumped-storage_hydroelectricit...
https://en.wikipedia.org/wiki/Ffestiniog_Power_Station
In fact, when you look at the list of pumped storage stations, the vast majority of them have dams:

When coal has a major incident, though, it still produces the same pollutants as if it's working correctly.
When nuclear has incidents, like the plants of Brunsbüttel and Krümmel that frequently had leaks, you end up with the highest leukemia quote worldwide [1].
Krümmel had major issues, with nuclear fuel being found in the area around the reactor, outside, on the ground, with the power plant leaking coolant frequently, and more incidents. [1]
Mismanagement with Nuclear can lead to far more problems than mismanagement with coal.

Yeah. No.
"Coal mining accidents resulted in 5,938 immediate deaths in 2005, and 4746 immediate deaths in 2006 in China alone according to the World Wildlife Fund"
So each year more deaths from coal accidents alone than the entire predicted, somewhat speculative and hard to ever prove death toll from Chernobyl over the next 20 or so years.
