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.

Heysham nuclear power station Heysham nuclear power station Heysham Power Station is a nuclear power station located in Heysham, Lancashire, England, operated by EDF Energy. The site is divided into two separately-managed stations, Heysham 1 and Heysham 2, both with two Reactors of the advanced gas-cooled reactor (AGR) type. On 18 October 2010, the British government announced that Heysham was one of the eight sites it considered suitable for future nuclear power stations. On 1 August 2016, Heysham 2's Unit 8 broke the world record for longest continuous operation of a nuclear generator without a shutdown. This record-breaking run exceeds the previous record of
