A nuclear reactor which can produces more fissile nuclear fuel than it consumes, because the neutrons breed fissile fuels from 238U and 232Th. Breeder reactors were popular until increasing reserves of uranium where found.
For instance, it was claimed that the release of one ton of plutonium into the atmosphere could give every person on earth lung cancer, and operating breeder reactors on a large scale would double the amount of plutonium on earth every ten years ("AEC Asks Billions for the Breeder" 1971).
