Quizplus · Accepted Answer

In breeder nuclear fission reactors, uranium-238 undergoes neutron capture and converts to plutonium-239, which is a fissile material and can undergo nuclear fission. As a result, more fissile material is produced than consumed, and the reactor can produce more fuel than it consumes, hence the name breeder reactor.
