Fast breeder reactor. Construction work underway on the BN-800 reactor at the Beloyarsk nuclear power plant. The BN-800 is a fast-breeder class reactor that uses highly-enriched uranium as a fuel. It is highly efficient in converting its uranium and will generate around 800 MW (megawatts) of electricity when in operation. The drawbacks of the fast breeder design are the need for a liquid sodium cooling system and the handling of its waste products, notably plutonium. Photographed at Beloyarsk in Russia.
