Chernobyl was operated by communists who had physicists pushing brooms and political appointees making decisions.
Fukushima was an old reactor that they sought to replace for years.
But, they didn't. They also didn't shut them down. Now they can't cap them. The point is that the power company did not do the responsible thing on behalf of safety. The Earth and all of its inhabitants will pay that price forever.
Nobody is about to shoulder the responsibility of operating those things, new or old. Greed is a Great Destroyer. That will never change. Nuclear power needs to be kept off the table until man evolves a great deal.
