Nuclear Provision: explaining the cost of cleaning up Britain's nuclear legacy

The Nuclear Provision is the best estimate of how much it will cost to clean up the UK’s 17 earliest nuclear sites over a programme lasting around 120 years.


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.
