About NDA

About NDA

The Nuclear Decommissioning Authority (NDA) is a non-departmental public body, created through the Energy Act 2004.

The NDA’s mission is to clean up the UK’s earliest nuclear sites safely, securely and cost-effectively with care for people and the environment.

Under the leadership of its Chief Executive, David Peattie, the NDA is undergoing a change in the way it is organised. The creation of ‘One NDA’ will transform how the NDA manages its businesses – working together to find more effective and efficient approaches to nuclear clean-up and decommissioning, on behalf of the UK tax payer.

There are around 16,000 people who help deliver the NDA’s mission and they make up one of the most advanced nuclear workforces in the world.

The NDA plans to capitalise on this wealth of experience and talent, harnessing the opportunities that come from the scale and breadth of the group.

In 2016 Sellafield Ltd became a subsidiary of the NDA and, in September 2019, Magnox Ltd also became a wholly owned subsidiary.

These are some of the key decisions that are changing the way the NDA operates to deliver its mission more effectively.

The NDA’s role is to secure the safe and efficient clean-up of Britain’s nuclear legacy at 17 sites across England, Wales and Scotland. This includes implementing policy on the long term management of nuclear waste. Created by the Energy Act (2004), The NDA is a Non-Departmental Public Body accountable to government for delivery of the mission and how taxpayer money is spent. The NDA reports to the Department for Business, Energy and Industrial Strategy (BEIS) and for matters affecting Scotland, it is responsible to Scottish ministers.
