Amentum appointed delivery partner for UK’s first Rolls-Royce SMRs
Amentum, a global leader in advanced engineering and technology solutions, has been selected as the programme delivery partner for the first deployments of the Rolls-Royce Small Modular Reactors (SMR) in the UK and the Czech Republic.
In the UK, Rolls-Royce SMR will deliver up to 1.5GW of low-carbon energy to the grid, supporting the UK’s net zero goals and creating more than 8,000 quality long-term British jobs. Rolls-Royce SMR and Amentum have signed a collaborative agreement giving Amentum the programme delivery role responsible for integration, oversight and governance, construction management and execution of SMR deployment.
Amentum will immediately work on ensuring the successful delivery of the first Rolls-Royce SMRs in the UK and the Czech Republic. In partnership with Rolls-Royce SMR, the company will deploy its full nuclear life cycle experience to oversee multi-functional programme execution and integrated planning to support the on-time and on-budget delivery of SMR-generated power.

John Heller, chief executive officer of Amentum, said: “The Amentum Rolls-Royce SMR collaboration advances the deployment of this transformational technology, a critical enabler in strengthening energy security in the UK and continental Europe. Amentum brings its industry-leading expertise as a project delivery partner for complex energy infrastructure to the forefront of small modular reactor deployment, ushering in the next generation of clean, reliable energy.”
Chris Cholerton, Rolls-Royce SMR chief executive, added: “By working with Amentum, an established and experienced global nuclear leader, we are combining our skills to build a powerful team that will enable successful delivery on our order commitments in multiple markets. This partnership plays directly to our strengths – ours in advanced manufacturing and engineering, and theirs in programme and construction excellence. It is a truly synergistic relationship that strengthens our overall offering.”
With global electricity demand expected to double in the coming decades, Rolls-Royce SMR offers a radically different approach to new nuclear: smaller, scalable, factory-built nuclear power plants that can be deployed, using a modular approach, for a range of applications.
Amentum was part of a consortium of supply chain companies that began working with Rolls-Royce in 2016 to develop a new kind of modular power station to meet the growing need for nuclear-generated electricity. Amentum is supported in this role by supply chain partners Turner & Townsend, Hochtief, Mace Consult and Unipart.
Ruth Todd CBE, Rolls-Royce SMR’s operations and supply chain director, said: “Partnering with Amentum to successfully deliver the Rolls-Royce SMR program is an important moment for us. This partnership supplements our existing capabilities with specialist expertise, geographical reach and provides access to the breadth of Amentum’s wider supply chain. It ensures we are equipped to deliver our programmes in the UK, the Czech Republic, Sweden and globally with confidence, scale and robust delivery assurance. The Amentum Rolls-Royce SMR collaboration advances our deployment plans significantly.”
