Nuclear Decommissioning Authority

The Nuclear Decommissioning Authority stands in Egremont, Cumbria, as the public body charged with cleaning up the United Kingdom’s civil nuclear sites. Its work began in 2004 under the Energy Act and now employs around 15,000 staff through subsidiaries across the country. The organisation manages five site licence companies, each responsible for different clusters of reactors and facilities. The NDA’s purpose is to remove hazards and find safe ways to store waste while keeping costs under control. It runs a £3.5 billion annual budget, mostly spent through contracts with specialist firms. Past projects have faced legal and financial challenges, including a Supreme Court case in 2017 over a major contract for Magnox plants. Independent reviews have criticised cost estimates, which have risen from £55.8 billion in 2005 to over £100 billion today. Visitors to Egremont can see the NDA’s presence through its local subsidiaries and research centres. The organisation owns land near several reactor sites and operates the National Nuclear Laboratory at Sellafield. A national archive called Nucleus in Wick, Caithness, holds records of the civil nuclear industry. The area also hosts training facilities such as Energus in West Cumbria, supporting the skilled workforce needed for decommissioning work.
