Nuclear power in the United Kingdom spent nuclear fuel was installed. The Nuclear Decommissioning Authority (NDA), formed in April 2005 under the Energy Act 2004, oversees and manages the decommissioning and clean-up of the UK's older Magnox power plants and the reprocessing facilities at Sellafield, which were transferred to its ownership from BNFL, and the former nuclear research and development facilities previously run by the UKAEA. In August 2005, the following sites were listed for decommissioning: Prior to the 2002 white paper "Managing the Nuclear Legacy", the cost of decommissioning these facilities had been estimated at around £42 billion. The white paper estimated the costs at
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%
