Guess what - just like the US almost half of the nuclear fuel in Europe comes from Putin controlled Rosatom. So building more nuclear plants will not make Europe any more free of Russian control than buying their gas. At the rate nuclear is progressing, we will be at 150% solar/wind/storage before any of these highly touted unproven technologies are proven.
And BTW when they were built, they all failed dramatically. For example at Santa Susanna a Sodium cooled reactor, the first commercial reactor to meltdown in 1959. As for the cleanup, "It was meant to be done in 2017, and the soil cleanup has not even begun. Boeing, NASA and the Department of Energy all signed legal agreements to clean up the site, and unfortunately, they are now trying to come out of those promises. Instead, they are proposing to leave as much as 98% of the contamination on-site permanently." Every time these LA hills burn, more radiation is released.
The rate of increase of wind and solar is currently about equal to one typical nuclear plant per year. Move fast and break things: the invisible yet infallible hand of the free market has spoken, nuclear is so totally dead. Except in countries like France, China, Russia and India that want to make more bombs and to keep their nuclear navies going.
