Rolls-Royce SMR and Amentum Set Stage for Nuclear Renaissance

Rolls-Royce SMR has appointed Amentum as its programme delivery partner (PDP), a pivotal role in enabling the successful delivery of the first Rolls-Royce Small Modular Reactors (SMRs).

Amentum (NYSE: AMTM) – with its extensive nuclear experience, established supplier network across the UK and Czech Republic, and global footprint – will enable programme delivery, provide integration, oversight and governance, and deliver the construction management programme for the deployment of Europe’s first SMRs.

Rolls-Royce SMR, a leading manufacturing and engineering business, has partnered with Amentum, a globally recognised leader in construction management. By combining their complementary strengths, the two companies are establishing the strongest possible team to enable the successful delivery of a fleet of Small Modular Reactors.

Rolls-Royce SMR Chief Executive, Chris Cholerton, said: “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 and transforming the way nuclear power is delivered.”

“We have secured a world‑leading partner that is fully invested in our success. 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.”

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.”

“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,” said Loren Jones, Senior Vice President and head of Amentum Energy and Environment-International business. “Amentum’s deep nuclear expertise and robust supplier network are ideal to support the growing energy requirements and drive long-term industrial growth.”

Ruth Todd CBE, Rolls-Royce SMR’s Operations and Supply Chain Director, added: “Partnering with Amentum to successfully deliver the Rolls-Royce SMR programme 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 and Czech Republic with confidence, scale and robust delivery assurance. The Amentum - Rolls-Royce SMR collaboration advances our deployment plans significantly.”

Rolls-Royce SMR has been selected as the preferred bidder by Great British Energy – Nuclear (GBE‑N) to build three units, by European utility ČEZ to build up to three gigawatts of new nuclear power in the Czech Republic and selected in the final two in Sweden by the utility Vattenfall.

The partnership with Amentum will enable the successful delivery of these contracts and further support our social value commitments to localisation in the UK and Czechia, creating and sustaining local jobs and providing opportunities across the supply chain.

Each Rolls-Royce SMR factory-built nuclear power station will produce 470MW of stable, affordable, emission‑free electricity – enough to power a million homes for at least 60 years.
