About the Opportunity
The DNWP Framework 2025 is a significant initiative aimed at addressing the UK's nuclear waste management challenges. It encompasses a £4.6 billion framework agreement that will support high-hazard risk reduction programmes on the Sellafield site. The framework will involve multiple specialist consortia to safely retrieve, treat, and store legacy nuclear waste while decommissioning obsolete facilities. The agreement will be in place for up to 15 years and will work collaboratively with suppliers at every stage, from planning to delivery. The framework replaces the Design Services Alliance and the Decommissioning Delivery Partnership, both of which are nearing expiry. The DNWP Framework is a key element of Sellafield Ltd's Overarching Acquisition Strategy and aims to ensure that the cleaning up of the legacy of historic operations on the site is achieved safely, efficiently, and sustainably.
