Site of a nuclear power station on the coast of Cumbria, NW England. It was known as Windscale until 1971, when the management of the site was transferred from the UK Atomic Energy Authority to British Nuclear Fuels Ltd. The plant is the world's greatest discharger of radioactive waste: between 1968 and 1979 180 kg of plutonium was discharged into the Irish Sea. In 1990 a scientific study revealed an increased risk of leukemia in children whose fathers worked at Sellafield from 1950 to 1985.
