Amentum (NYSE: AMTM) has been appointed as the program delivery partner for the first deployments of the Rolls-Royce Small Modular Reactor (SMR), marking a significant step in the rollout of next-generation nuclear energy in the UK and Europe.
Under a new collaborative agreement, Amentum will take responsibility for programme integration, oversight and governance, as well as construction management and execution of SMR deployment. The partnership will support the delivery of up to 1.5GW of low-carbon electricity to the UK grid, contributing to national net zero targets and creating more than 8,000 long-term jobs.
Amentum will immediately support the first SMR projects in the UK and the Czech Republic, applying its full nuclear lifecycle experience to integrated planning and multi-functional programme execution, with a focus on on-time and on-budget delivery.
John Heller, Chief Executive Officer of Amentum, said the collaboration advances deployment of a “transformational technology” that strengthens energy security across the UK and continental Europe, bringing Amentum’s programme and construction expertise to the forefront of SMR delivery.
Rolls-Royce SMR Chief Executive Chris Cholerton said the partnership combines complementary strengths, pairing Rolls-Royce’s advanced manufacturing and engineering capabilities with Amentum’s programme and construction excellence to enable confident delivery across multiple markets.
The partnership will support SMR deployment not only in the UK and Czech Republic, but also in Sweden and globally, providing scale, delivery assurance and access to Amentum’s wider supplier network. Amentum is supported by supply chain partners including Turner & Townsend, Hochtief, Mace Consult and Unipart.
With global electricity demand forecast to double in the coming decades, Rolls-Royce SMRs offer a modular, factory-built approach to nuclear generation, designed for scalable deployment across a range of applications.
