The Nuclear Provision covers the Nuclear Decommissioning Authority’s 17 historic nuclear sites across the UK. Some sites date back to the very earliest days of the industry in the 1940s.

Decommissioning work is carried out by Site Licence Companies (SLCs) on behalf of NDA.

We explain the background to the origins of the UK’s nuclear legacy and the issues with forecasting the cost of such a long-term mission.
