We ensure the safe and efficient clean-up of the UK’s nuclear legacy. This involves decommissioning and demolishing all buildings, as well as treatment and disposal of associated waste, both radioactive and conventional. The Nuclear Decommissioning Authority (NDA) is a non-departmental public body created through the Energy Act 2004. We employ just over 200 staff. Our headquarters are based in west Cumbria. We own 17 sites across England, Wales and Scotland, some dating back to the 1940s, plus the associated liabilities and assets. We report to the Department for Business, Energy and Industry Strategy (BEIS); for some aspects of our work in Scotland, we are responsible to Scottish ministers. Our role is strategic: we establish the overall approach, allocate budgets, set targets and monitor progress. We do not have a hands-on role in cleaning up our facilities. Instead, we deliver our mission through others, primarily Site Licence Companies (SLCs) and subsidiaries: Sellafield Ltd, Dounreay Site Restoration Ltd, Magnox Ltd, Low Level Waste Repository Ltd, Radioactive Waste Management Ltd, International Nuclear Services Ltd, Direct Rail Services Ltd.
