Nuclear power in the United Kingdom Nuclear power in the United Kingdom Nuclear power in the United Kingdom generates around a quarter of the country's electricity as of 2016, projected to rise to a third by 2035. The UK has 15 operational nuclear reactors at seven plants (14 advanced gas-cooled reactors (AGR) and one pressurised water reactor (PWR)), as well as nuclear reprocessing plants at Sellafield and the Tails Management Facility (TMF) operated by Urenco in Capenhurst. The United Kingdom established the world's first civil nuclear programme, opening a nuclear power station, Calder Hall at Windscale, England, in 1956. At the peak in 1997, 26% of
Embalse Nuclear Power Station Embalse Nuclear Power Station The Embalse Nuclear Power Station () is one of three operational nuclear power plants in Argentina. It is located on the southern shore of a reservoir on the Río Tercero, near the city of Embalse, Córdoba, 110 km south-southwest of Córdoba City. The plant is a CANDU Pressurised Heavy Water Reactor (PHWR). It employs natural uranium (that is, with 0.72% of U) and uses heavy water for cooling and neutron moderation. It has a thermal power of 2,109 MW, and generates 648 MW of electricity, with a net output of about 600 MW, supplying nearly 4.5%
