Nuclear Decommissioning Authority

The Nuclear Decommissioning Authority (NDA) is responsible for the decommissioning and clean-up of the UK’s civil public sector nuclear legacy. However the NDA does not directly manage the facilities it owns. Instead the management and delivery of site programmes is via the management and operations contracts with licensed operators, referred to as Site Licence Companies (SLC).

It is the role of the SLC to manage the site, prepare site plans and manage the supply chain. NDA introduces competition to the strategic management of the SLCs by tendering for Parent Body Organisations (PBO). The PBO own the shares in the SLCs and provide secondees into the SLCs management team with the aim of improving performance, encouraging innovation and increasing value for money.
