breeder reactor. (n.d.). Retrieved January 14th, 2019, from https://www.yourdictionary.com/breeder-reactor
A nuclear reactor that is used to create fissionable material (such as plutonium-239) by exposing nonfissionable material (such as uranium-238) to radiation. The source of the radiation is usually some other fissionable material. Breeder reactors produce more fissionable material than they use up.
