Sellafield has awarded a framework with a maximum value of £4.6bn to support high hazard risk reduction programmes on the Sellafield site, through the Decommissioning and Nuclear Waste Partnership (DNWP).

The framework agreement will be in place for up to 15 years. DNWP will support activities related to retrieving waste materials from the Sellafield site’s oldest facilities as well as treating and storing those materials and decommissioning redundant assets.

The confirmed winners of the four lots are:

Lot 1 (Remediation): A2R (AtkinsRéalis in a joint venture with Altrad Support Services); Amentum

Lot 2 (Retrievals): The Decommissioning Alliance (AtkinsRéalis, Amentum Clean Energy and Westinghouse Electric Company UK)

Lot 3 (Retrievals): Nuclear Decommissioning Solutions (Altrad, Cavendish Nuclear and Shepley Engineers)

Lot 4 (Integrated Nuclear Waste Partner): A2R

DNWP replaces and builds on the outgoing Design Services Alliance (DSA) and Decommissioning Delivery Partnership (DDP).

James Riddick, Sellafield chief supply chain officer, said: “Cleaning up the legacy of historic operations on our site is at the heart of our mission. It is important that we achieve this safely, efficiently, and sustainably - our supply chain, and this partnership plays a key role in that.

“We’re pleased to welcome our new partners. Their specialist capabilities and teams, working alongside our skilled Sellafield workforce, will help us deliver our mission and drive progress both on site and across our wider community.

“Just as importantly, these partners share our values and our commitment to creating lasting social value for the communities we serve.”

Chris Conboy, managing director - nuclear EMEA, AtkinsRéalis, on behalf of A2R, said: “Altrad and AtkinsRéalis have supported Sellafield Ltd for over 3 decades. Through the DNWP Framework, we will continue to deploy our knowledge, commitment and shared expertise to deliver complex remediation and waste treatment services safely, sustainably, and efficiently, helping Sellafield to deliver on its mission and in the lasting impact it has on the local community.”
