Even with the disasters, nuclear is damn safe. Methods like coal don't fail catastrophically, but they gradually poison the air and kill via pollution. Nuclear doesn't do that, nuclear kills all in one go, but averaged out, nuclear still kills far less. It's just sudden failure makes for better headlines.
Of course you don't count that. We're talking about human deaths, not environmental degradation. But even then, I'd bet the damage done from thermal pollution is far easier to manage than coal dust pollution. One is entirely localised, the other literally crosses continents.
