Webapplication, the fusion-fission hybrid reactors can be further utilized as a neutron source for R&D of fusion reactor itself. Since 1986, many studies on the fusion-fission hybrid reactors have been performed to evaluate the feasibility and attractiveness of the hybrid systems for transmutation of nuclear wastes and breeding of fissile fuel [1~11].

Fast reactors generally have an excess of neutrons (due to low parasitic absorbtion), the neutrons given off by fission reactions can “breed” more fuel from otherwise non-fissionable isotopes or can be used for another purposes (e.g.,transmutation of spent nuclear fuel). WebNov 1, 2024 · The case is made that fusion breeding (that is using fusion neutrons to breed nuclear fuel for use in conventional nuclear reactors) is the best objective for the fusion program, and is a much better fit to today's and tomorrow's nuclear infrastructure than is its competitor, fission breeding. howdens glossop
