Does nuclear fusion produce waste?

Best Answers

Bottom line: Fusion makes a ton of energy with little waste. That waste comes out both directly and indirectly. Directly - it depends of which fuel you burn: Deuterium, tritium. This makes: heat, light, helium, and neutrons; probably also un-burned deuterium and tritium. read more

Nuclear fusion produces only a small amount of waste relative to current nuclear fission reactors, the waste fusion tends to produce has significantly shorter life (typically less than 30 years for neutron activated fusion chamber materials). read more

Nuclear fusion does produce radioactive waste. However, in contrast to fission produced wastes, they are short lived and decay to background levels in a very short time. While great strides have been made over the past few decades, the high cost of research, and very expensive hardware, limits most of the work to multi-national consortia. read more

The 14.1 MeV neutrons irradiate the surrounding structure, and when the neutron is ultimately absorbed, the absorbing nuclide generally becomes radioactive In this sense, fusion does produce waste products in the form of irradiated (and activated) structural materials, which ultimately have to be disposed in some appropriate facility. read more
