Including all nuclear power plant disasters, it still has far fewer deaths per gigawatt hour compared to everything except large scale solar installations (not personal rooftop solar, which is much higher due to falls). It's the money, not the safety, that's the problem.
How do you know that? There are no reliable figures on the Chernobyl deaths because there was and is a massive ongoing cover-up. Same goes for Fukushima, Windscale and whatever the Soviets managed to sweep under the rug. Until you come up with some actually reliable figures, I suggest you stop repeating this obvious propaganda talking point
Safety per gigawatt hour sounds like it doesn't take into account what we do with all the radioactive waste of which there'd be much more of if nuclear power was scaled up drastically.
Could do with some more, especially more modern versions with less waste product and more efficient generation.
