Fast breeder Reactors:
The fast breeder or fast breeder reactor (FBR) is a type of fast neutron reactor that produces more fissile material than it consumes.
A fast neutron reactor, commonly called simply fast reactor, is a nuclear reactor design that uses no moderator but instead relies on fast neutrons to sustain its chain reaction. Achieving this requires high-grade fuel such as enriched uranium or plutonium, but once this has been provided for the initial startup the reactor produces its own fuel and a surplus that can then be used to start other FBRs, hence the concept of a breeder.
The FBR program of India includes the concept of using thorium-232 to breed fissile uranium-233. India is also pursuing the thermal breeder reactor again using thorium. A thermal breeder is not possible with purely uranium/plutonium based technology. Thorium fuel is the strategic direction of the power program of India, owing to their large reserves of thorium, but worldwide known reserves of thorium are also some three times those of uranium.
