= Fast Breeder Test Reactor
{wiki=Fast_Breeder_Test_Reactor}
The Fast Breeder Test Reactor (FBTR) is a type of nuclear reactor that utilizes fast neutrons to sustain a nuclear fission chain reaction. The primary function of a fast breeder reactor is to generate more fissile material than it consumes, effectively "breeding" new fuel. This is achieved through a process that converts fertile material, such as uranium-238 or thorium-232, into fissile isotopes, such as plutonium-239 or uranium-233.
