We're charged, on behalf of government, with the mission to clean-up the UK’s earliest nuclear sites safely, securely and cost effectively.
We’re committed to overcoming the challenges of nuclear clean-up and decommissioning and do this work with care for our people, communities and the environment, with safety, as always, our number one priority.
Our 17 sites reflect the UK's nuclear legacy and include the first fleet of nuclear power stations, research centres, fuel-related facilities, and Sellafield, which has the largest radioactive inventory and the most complex facilities to decommission.
Our current decommissioning portfolio is set to expand with transfer of the second generation of commercial power stations, the advanced gas-cooled reactor fleet owned by EDF, beginning from 2026.
Current plans indicate it will take more than 100 years to complete our core mission of nuclear clean-up and waste management.
As owners of one of the largest nuclear decommissioning and remediation programmes in Europe, our main priority is to lead the work across the NDA group and develop the strategy for how it should be carried out.
We also play an important role in supporting government’s aspiration for the UK to be a global leader in the civil nuclear sector, and we invest in projects to create lasting positive impacts for our site communities.
We strive to deliver best value for the UK taxpayer by focusing on reducing the highest hazards and risks, while ensuring safe, secure, and environmentally responsible operations at our sites.
