The Nuclear Decommissioning Authority, abbreviated NDA (German authority for the decommissioning of nuclear installations ) has in the UK overseeing the decommissioning, dismantling and cleaning of certain nuclear facilities. According to a law adopted in 2004 (Energy Act ), the Authority was established on 1 April 2005. She has taken over the designated operating system in their property, while the necessary work is usually carried out by other organizations and companies.

The seat of authority is in the Westlakes Science & Technology Park, near the northeastern English port of Whitehaven.
