Under the Projects and Asset Care Execution (PACE) framework contract, Amentum and its supply chain partners will support Sellafield Ltd’s spent fuel management and retrievals mission by providing full lifecycle capabilities including engineering and design, procurement, installation and plant modification, project management and controls, commissioning, dismantling, removal and ongoing asset care.

“Sellafield Ltd has selected us and our trusted suppliers because of our record of excellent delivery performance, collaborative behaviors and constant innovation and improvement, driven by application of technologies such as digital visualization and advanced robotics,” said John Heller, Chief Executive Officer of Amentum. “PACE provides a significant, long-term growth opportunity for Amentum at Sellafield, building on our existing capability and relationships while also enabling us to deliver a broader, integrated full lifecycle scope on higher value projects across engineering and asset care.”

"Our mission is to create a clean, safe and secure environment for future generations. To do this we must ensure our assets remain safe, reliable and fit for the future,” said Matthew Johns, Chief Engineer, Sellafield Ltd. “The PACE agreement is an important step to strengthen our asset care capability. It will provide the expertise we need to maintain a high standard of safe and efficient delivery.”

Formal award of the framework agreement will follow when final contractual arrangements are concluded.

Lot 1 of PACE will be delivered by OneAxIoM, a joint venture between Amentum and Mitie Plc, supported by key supply chain partners Assystem and Mott MacDonald. The initial contract duration is nine years, with an optional six-year extension.
