Amentum, a specialist in advanced engineering and technology solutions, has been chosen as the program delivery partner for the first deployments of the Rolls-Royce Small Modular Reactor (SMR)
In the UK, Rolls-Royce will provide up to 1.5GW of low-carbon energy to the grid, supporting the UK’s net-zero goals and creating over 8,000 jobs.
Rolls-Royce SMR and Amentum have signed a collaborative agreement, which will give Amentum the program delivery role, responsible for integration, oversight, and governance, construction management, and execution of SMR deployment.
Amentum will work to ensure 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 entire nuclear life cycle experience to oversee multi-functional program execution and integrated planning to support the on-time and on-budget delivery of SMR-generated power.
John Heller, CEO 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.”
Loren Jones, senior vice president and head of Amentum’s Energy and Environment-Internal business, said, “Amentum will support the deployment of a fleet of Rolls-Royce SMRs, contributing to our growth and our plan to create new jobs in the UK over the next four years. Amentum’s deep nuclear expertise and robust supplier network are ideal to support growing energy requirements and drive long-term industrial growth.”
