Ø            Fast Neutron Breeder Reactor

In a fast neutron breeder reactor, enriched nuclear fuel undergoes nuclear fission inside a reactor core.  A blanket of fissionable material is placed around the reactor core to capture any excess neutron to transform into fissile material.  Liquid metal is used as a coolant for the nuclear fuel and takes the heat to a steam generator to raise steam for the turbine-generator.  The nuclear fuel can be replaced when the reactor is operating.
