Fast breeder reactor. Reactor hall of the BOR-60 fast breeder nuclear reactor in Dimitrovgrad, Russia. Fast breeder reactor cores use plutonium fuel surrounded by uranium; they are cooled by molten sodium metal. The break-up (fission) of plutonium atoms provides energy and fast subatomic particles called neutrons. Some of the neutrons are absorbed by the uranium to form more plutonium that can be used as fuel. The BOR-60 is an experi- mental reactor capable of generating 12 megawatts. It is used for performing endurance tests of fuel, fuel sub-assemblies & new cores. Opened in 1969, it is thought to have suffered from over 180 coolant leaks & equipment breakdowns.
