Difference between Fast Breeder Reactors (FBR) and Light Water Reactors (LWR)

FBR cycle use Plutonium as fissile fuel and also use fast neutron spectrum to undergo fission compared to LWR. This neutron spectrum enable the creation of new fissile plutonium inside the core itself using breeding material. FBR cycle also help to stabilize dangerous fission product (FP) and Minor actinides by transmutation.

The necessity of FBR cycle

By the generation of new fissile material inside the reactor, FBR cycle enhance energy security and autonomy of a country by increasing dramatically the potential reserve of domestic nuclear fuel.
