> France's cost of generation is super low
Source? The real TCO isn't. Fact: EDF gobbled during decades public money and various advantages, and is now crushing under a >50 billions € debt
> the carbon intensity of generation is 10 times lower than Germany's
In the 1960's France coal reserves were vanishing (France switched to nuclear) while Germany's were massive (in RDA it was huge). This is the root cause.
Nope. This is now illegal in most nations. Even recyclable blades now exist, and old ones are more and more burnt in cement killns.
> uranium
> spent fuel can be recycled (and a lot of if is even today!)
Nope. Source? Even France doesn't recycle (MOX) more than a few percent, and it only is recyclable once. Industrial real 'eternal' recycling (possible with renewables, as most components such as copper or aluminium are 'infinitely' recyclable at human timescale) of uranium isn't achieved anywhere. If it is, please state where and how.
> we know how to extract it from seawater
This is nothing more than an old dream. Please state (source) where it is, at industrial stage. It simply isn't, anywhere, and all attempts (since the 1970's) failed, and this is a well-know fact.

In Germany nuclear-produced electricity peaked at 30% (around 1999), electricity being there around 12% of the consumed energy. Far, from the huge deal sometimes touted. ( https://en.wikipedia.org/wiki/File:Energy_mix_in_Germany.svg )

So? The facts remain: they don't use any land and offer sanctuaries to exhausted seas.
> and they basically can't be recycled
Nope, they can be recycled and in more and more nations this is even mandatory. In France: https://factuel.afp.com/le-socle-des-eoliennes-resteront-dan...
> after their useful lifespan of 20 years
Nope, even with such a young industry there are many counter-examples of big (industrial) old wind turbines. https://www.tvindkraft.dk/stories/a-new-nacelle-back-end/
> They have to be buried
Nope. This is now illegal in most nations. Even recyclable blades now exist, and old ones are more and more burnt in cement killns.

Is playing with words your best counter-argument? I quoted a source, everyone may check my assertion: https://www.researchgate.net/publication/222817608_Life_cycl...
Sheer facts happening since the advent of industrial renewables indicate that many believe that the 'renewable sources' path is the best one: https://ourworldindata.org/grapher/nuclear-renewables-electr...
