Then there's a problem with nuclear fuel. The sources are mostly countries you don't want to depend on.
You are of course right with your assessment that nuclear is green, safe and eco-friendly. That's a hard one to swallow for a lot of eco activists.
Nuclear fuel storage is relatively straightforward, and volumes have potential to be reduced 30x through recycling.
In Ukraine, profits from all nuclear plants will cover damages, caused by Chornobyl, in 1000-5000 years IF nothing more will happen to Chornobyl or other an other nuclear power plant in those years, which is unlikely.
Sure, these days its too expensive in relative terms but switching back to fossil fuels due to all the Chornobyl/Three Mile panic (but mainly likely because of the cost) might end up being one of the bigger mistakes in human history.
