What does a breeder reactor do? A.)It uses controlled rates of reaction to conserve nuclear fuel. B.)It creates its own control rods out of the lead resulting from uranium decay. C.)It creates independent chain reactions that then separate from their parents and become new energy sources. D.)It creates its own neutron bombardment beam out of the neutrons that escape from the uranium as it decays. E.)It produces plutonium from uranium and thereby creates more nuclear fuel than it uses.
