Three Mile Island was the worst nuclear accident in US history. Was mainly caused by poor design of human feedback systems which caused operational confusion and lead to a catastrophic failure.

      Some nuclear reactor designs can be used for breeding plutonium, as well as for producing power. It was a bigger issue in the past, though; nowadays there are plenty of well tested designs that aren’t capable of breeding plutonium

          Thorium was being tested for viability alongside uranium, and got scrapped not because it wasn’t a feasible design, but because it couldn’t produce weapon grade material as a byproduct. Some countries are finally exploring thorium again, hopefully with some success.
