So... The claim safeguards created after major accidents happened are necessary for safety is extraordinary?
They can probably be improved, but then, you keep comparing with Russia and China as if those two countries cared about the safety of their population.
(Anyway, there was a recent paper here on HN that looked into the issue and discovered the costs are more of a consequence of the small size of the industry than the safety constraints. That kind of problem is hard to fix, but if you want to try, it's a worthy cause.)

You seem willfully ignorant of how power generation economics work. Or are you talking about the opportunity costs of choosing the cheapest option?

Hum... The first Google result I get seems to be using this data:
TLDR, the worst kind of panel they measured lost less than 2% of it's capacity per year, so about half of its capacity in 50 years. Some slightly more expensive ones lost less than 1% per year.

Oh, there's a comment on this thread about how hydro-storage can hold about 10 times the requirements for the world. There was one recently about how hydrogen is perfectly sufficiently, as flawed as it is. And of curse, there is always some weird design appearing once in a while, that nobody invests in, of course, because nobody has ever invested on energy storage.

What a lack of principled thinking, this equating batteries with lithium. Lithium isn't that great for stationary storage in any way other than the batteries factories already existing.

Not more of them than we are using now. Anyway, no, 100% nuclear doesn't work well either, it would be incredibly expensive. None work without storage. (By the way, you seem to have an incorrect model of why renewables don't decrease their production when they overproduce. Most of them can do it perfectly well if the overproduction becomes too severe, it just brings costs.)
> regarding lithium availability
And then we go into the "what is the meaning of that "reserves" word" treadmill... You may want to look into it in detail, as both lithium and uranium have a problem with that word. None has a problem of availability.
Anyway, about sea extraction, people have done it economically for lithium, but for uranium it's many orders of magnitude harder.
Also, about this:
> reactors that reuse MOX fuel (like e.g. France does) can significantly (how much ?) reduce uranium consumption.
In theory, recycling can reduce consumption around 1000 times (varies with every detail on the lifecycle). Breeding can do much more (that's why thorium is interesting).
Yep, thorium brings several engineering problems. Uranium breeding brings a lot of them too.
Overall, breeding reactors are currently way too expensive. They are interesting on the long term, once those solvable problems get solved. I do agree they have no place at all in a discussion about current energy crisis or global warming.
