AtkinsRéalis Group Inc. has signed a new five-year framework agreement to continue its civil works role at Sizewell C, a 3.2-GW nuclear plant in southern England. The company will act as design partner for permanent civil works, building on years of support to the project.
Scope of Work and Expertise
AtkinsRéalis is providing multidisciplinary design and engineering services across the permanent plant design, including the Conventional Island, Balance of Plant, Heat Sink Buildings and Ancillary Works. This builds on its extensive role in planning, consenting and enabling work phases at Sizewell C.
“Common outcomes and shared responsibility across delivery partners maximize opportunities for innovation and collaboration,” said Ian L. Edwards, President and CEO of AtkinsRéalis. “This appointment reinforces AtkinsRéalis’ expertise in delivering new nuclear build programs and the confidence placed in our teams at Sizewell C to help de-risk delivery and achieve greater certainty for this nationally significant project.”
Digital Tools and Community Impact
The agreement enables AtkinsRéalis to continue bringing new and established digital tools into the civil works program. Joe St. Julian, President, Nuclear, AtkinsRéalis, noted: “AtkinsRéalis has played a significant role in design and engineering management at Sizewell C since 2019, bringing knowledge, experience and learnings from a decade of delivery at Hinkley Point C. Our design and engineering teams have pioneered new digital technology and data-led design to streamline schedules, increase certainty and mitigate program risks at Sizewell C. This new agreement renews our commitment to realizing the full benefits of replication and unlocking even greater efficiencies through excellence in delivery.”
AtkinsRéalis has reinforced its commitment to building a lasting impact in the community, including work with local supply chains and strategic programs with schools and further education facilities to build interest in STEM careers. These programs have already reached over 1,500 students at more than 50 schools and colleges in and around Suffolk.
UK Nuclear Program Support
In the UK, AtkinsRéalis supports EDF’s operational fleet and new build program, including design and civil, mechanical, electrical, process and nuclear engineering support for Hinkley Point C. Prior to this agreement, AtkinsRéalis delivered a broad program of design, engineering and project management at Sizewell C, including design and engineering of vital utilities and water networks, earthworks, buildings and structures; new infrastructure including upgrades to local rail and road links, new marine and landing facilities; along with new offsite accommodation campuses, freight management and park and ride facilities.
