British Nuclear Fuels plc or BNFL manufactures and transports nuclear fuel (notably MOX), runs reactors, generates and sells electricity, reprocesses and manages spent fuel (mainly at Sellafield), and decommissions nuclear plants and other similar facilities. BNFL is owned by the British government. BNFL has undergone major changes recently: the formation of a new holding company on 1 April 2005, the transfer of its nuclear sites to the Nuclear Decommissioning Authority and the sale of its Westinghouse Electric Company subsidiary in February 2006.
