> still produces nuclear waste, Yes but you only have to worry about radioactive reactor parts and other structural materials, not spent fuel. > still capable of producing nuclear weapons material, I don't get this argument at all. A fusion reactor does not generate heavy elements such as uranium or plutonium. However, the fusion reaction can be a neutron source which could be used to convert heavy elements such as thorium or uranium into fissile material. But by no means would this be part of any power generation station. This leads us to... > We'd be better off just coming up with good fast breeder reactor designs So this neutron source is somehow more clean and secure than the other one you just dismissed?
