The Department of Energy figures for 1990/91 on the plutonium produced at Britain`s civil nuclear power stations, reprocessing activities at Sellafield, and the civil plutonium stocks are given. These figures are published annually and are compiled from data supplied by Nuclear Electric plc, Scottish Nuclear Ltd, British Nuclear Fuels plc (BNFL) and the United Kingdom Atomic Energy Authority (UKAEA). Reactor discharges and dispatches from site of irradiated fuel and the stocks of plutonium held in irradiated fuels are listed. BNFL figures show the cumulative stocks of plutonium held in irradiated fuels. 156 kg of separated plutonium was imported from France under the first reactor collaboration. 2210 kg of unseparated plutonium was imported as irradiated fuel.
