Sellafield £4.6 billion high hazard framework

Sellafield has awarded a new £4.6 billion high hazard risk reduction framework contract to Amentum (remediation and hazardous waste retrieval), Atkins Realis and Altrad (decommissioning and nuclear waste management.), through the Decommissioning and Nuclear Waste Partnership (DNWP).

The Decommissioning Alliance (TDA) is joint venture involving Amentum, AtkinsRéalis & Westinghouse, handling pond retrievals.

The framework agreement will focus on the retrieval, storage and treatment of waste materials from the oldest facilities on the site and will be in place for 15-years.

All the companies involved with develop a sustainability plan to enhance collaboration with local priorities, ROI and delivering impact.

James Riddick, Sellafield Ltd 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.”

Sellafield & RAICo facility simulator

Virtual Innovation Enhances Nuclear Waste Handling Safety at Sellafield

A cutting-edge simulation project is transforming how nuclear waste is managed at one of the UK’s most hazardous legacy facilities—Sellafield’s Pile Fuel Cladding Silo (PFCS). Originally built in the 1950s, the PFCS is now being decommissioned, with robotic systems playing a vital role in safely handling radioactive waste.

To reduce risk and downtime during upgrades to these robotic systems, RAICo and Sellafield Ltd developed a virtual replica of the facility using advanced 3D scanning, CAD modelling, and RAICo’s RHOVR simulation platform. This digital twin allows engineers to test software and hardware changes in a photorealistic environment before applying them in the real facility.

The result? Fewer human entries into hazardous zones, reduced downtime, and safer, more efficient upgrades to robotic systems. The simulator is already in use at Sellafield’s Engineering Centre of Excellence and could soon be adapted for other waste-handling operations across the site.

This project is a powerful example of how robotics, simulation, and cross-sector collaboration are accelerating innovation in nuclear decommissioning—while keeping people safe and building the digital skills needed for the future.
