Breeder reactor - Wikipedia
Breeder reactor - Wikipedia

A ,breeder reactor, is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232 that is loaded into the reactor along with fissile fuel. . Breeders were at first found attractive because they ...
