AtkinsRéalis appointed to support EDF and Sizewell C across UK nuclear portfolio Français News provided by AtkinsRéalis May 26, 2026, 07:45 ET Share this article Share to X Share this article Share to X MONTREAL , May 26, 2026 /CNW/ - AtkinsRéalis Group Inc. (TSX: ATRL ), a world-class engineering services and nuclear company with offices around the world, has been appointed by EDF (Électricité de France) and Sizewell C Limited to a broad Professional Services framework. The appointment extends the multidisciplinary work AtkinsRéalis delivers across EDF's existing fleet of nuclear power plants and its new build Hinkley Point C program for an initial five-year term, with the option to extend by a further five years. It also encompasses engineering services delivered at Sizewell C nuclear new build program.

The framework ensures AtkinsRéalis will continue to support EDF as a trusted delivery partner during a vital transition period as some of its existing plants enter vital life extension programs, others shift towards the end of operational life, and as Hinkley Point C prepares for operations as the UK's first large-scale reactor for a generation. The inclusion of Sizewell C will also help to realize the full benefits of replication as the AtkinsRéalis team applies the knowledge and experience from Hinkley Point C to the new build program as it enters construction phase. "EDF has been a major client to our Nuclear business for over two decades, and this framework is a continuation of the vital work we have been delivering across operational and new build programs for EDF Energy and Sizewell C in the UK," said Ian L. Edwards, President and Chief Executive Officer, AtkinsRéalis.

"Our proven ability to provide a breadth of capabilities strengthens our role as a strategic partner with EDF and reinforces our leading position as a truly end-to-end engineering services provider in the global nuclear industry." Under the new Professional Services Framework, AtkinsRéalis will support EDF Nuclear Services, EDF Nuclear Operations, Hinkley Point C and Sizewell C across more than 60 different technical and project delivery disciplines, from design and engineering to program management and consultancy. "There are over 3000 experienced AtkinsRéalis employees working across civil nuclear programs in the EMEA region, from structural and mechanical engineers to specialists in digital design, project delivery and decommissioning," said Joe St Julian, President, Nuclear, AtkinsRéalis. "This new framework enables EDF and Sizewell C to seamlessly access our specialists for any of their UK programs, reinforcing our ability to act as a trusted delivery partner during this crucial period of their nuclear operations." The latest appointment builds on AtkinsRéalis' well-established partnership with EDF Energy, working across its operational and new build program in the UK for over 25 years, including both Hinkley Point C and Sizewell C in its UK EPR program.

In 2025, AtkinsRéalis and EDF also signed a strategic partnership agreement to collaborate on new nuclear reactor opportunities internationally.
