Assystem is an international engineering and digital services company dedicated to the clean energy switch. The Group has multiple offices in the UK, including at Culham, and it is the second largest nuclear engineering company in the world, with over 6000 specialists in its employ.
Its participation in the UKAEA’s Engineering Design Services (EDS) and Embedded Engineering Resource (EER) frameworks forms part of a long-term commitment to the development of UK fusion capability, harnessing a blend of UK skills, decades of experience on international fusion projects such as ITER and collaboration with UK fusion specialist SMEs.
Through the EDS, Assystem was pleased to contribute its expertise to the delivery of Phase 1 of the ANNA thermohydraulic test rig at the UKAEA’s new facility in Rotherham. In this project, our engineers progressed the preliminary concept design, including an initial layout of the rid and a comprehensive process flow diagram.
The test rig delivers a range of flow scenarios and provides real-world test data thanks to the inclusion of windows in the vessel, which enables the validation of Computation Fluid Dynamics (CFD) analyses. While its main function is in testing PWR, the technology is expected to have the potential to be applied across a range of fusion and reactor technologies.

Atkins is one of the world’s leading design, engineering, and project management consultancies. As part of the SNC-Lavalin group, we can call upon the experience of over 35,000 staff spread across 50 countries to solve our clients’ most challenging problems. We’re helping UKAEA to commercialise fusion energy from across our UK offices, including Epsom, Bristol, Sheffield, Birmingham, Warrington, Glasgow and Culham.
Atkins is a Tier 1 supplier to UKAEA on both the Embedded Engineering Resources (EER) and Engineering Design Services (EDS) frameworks. As part of EER, our talented engineers are embedded within UKAEA teams to support diverse programmes such as STEP, H3AT, MAST, and JET.
Within EDS, we have a proven track record of successfully delivering complex, multi-disciplinary projects from our own offices, such as our recent STEP Integrated Plant Solution (IPS) appointment. Our team worked collaboratively with UKAEA to develop the maintenance concept for this first-of-a-kind prototype fusion power plant. We developed the handling philosophy and facility layouts for the Tokamak Building and the Active Maintenance Facility. Our core mechanical team was supported by our subject matter experts in structural, waste management, HVAC and safety hazards, developing a range of solutions to maintain the Tokamak along its lifecycle.
As a trusted supplier to the STEP programme, we hold positions such as Tranche 1 Engineering Delivery Partner, and recently supported the selection of West Burton as the home for STEP through our Site Selection and Development partner contract.
