One thing those disasters have shown about nuclear is that a single accident -- even if there is little loss of life -- absolutely ruins the economics of nuclear power. Even an accident with no loss of life will cost an absolute fortune to clean up and decommission due to how hard it is just to handle and transport the material.

Prior to Fukushima nuclear power was fairly economical in Japan. Post-Fukushima and in retrospect it would have been cheaper to cover every roof in Japan with solar panels, build loads of offshore wind, and build massive energy storage facilities and pumped storage reservoirs.
