Amentum and Rolls‑Royce SMR Forge a Defining Partnership for Europe’s Nuclear Future
A major step toward a revitalised nuclear landscape in Europe is taking shape as Rolls‑Royce SMR and Amentum formalise a partnership designed to deliver the first wave of Small Modular Reactors (SMRs) in the UK and the Czech Republic.
This collaboration marks a pivotal moment for the sector, uniting Rolls‑Royce SMR’s advanced engineering and manufacturing capabilities with Amentum’s global expertise in programme delivery and complex nuclear infrastructure. Together, the companies are positioning SMRs as a cornerstone of future clean‑energy systems across Europe.
Rolls‑Royce SMR’s appointment of Amentum as its programme delivery partner places Amentum at the heart of Europe’s first SMR deployments. The company will play a central role in integrating and overseeing all major elements of delivery, governance, construction management, and multi‑disciplinary programme execution.
With a well‑established footprint in the UK and deep technical expertise across the full nuclear life cycle, Amentum is set to guide these projects from inception to grid integration, ensuring they remain on schedule and on budget. The UK stands to benefit enormously from this union.
Rolls‑Royce SMR expects to provide up to 1.5 GW of low‑carbon power to the national grid while supporting national net‑zero ambitions. Beyond energy contributions, the programme is expected to generate more than 8,000 skilled long‑term jobs, creating significant opportunities across engineering, construction, and the wider nuclear supply chain.
Czechia will also see major investment through the deployment of up to 3 GW of new SMR‑based capacity, reinforcing the region’s commitment to clean, reliable nuclear energy.
Both organisations emphasise the strategic value of the partnership. Rolls‑Royce SMR underscores that combining its advanced manufacturing leadership with Amentum’s proven delivery capabilities will allow multiple international projects to be executed with confidence and consistency.
Amentum, meanwhile, highlights the collaboration as a catalyst for strengthening European energy security and accelerating the transition to resilient, low‑carbon infrastructure. The shared commitment reflects a vision not only to deploy early SMR projects but to lay the groundwork for a fleet‑based approach that can scale rapidly across global markets.
This next generation of nuclear technology is designed around factory‑built precision and modular construction, an approach that dramatically reduces on‑site work, minimises cost risk, and avoids the lengthy timelines that have historically challenged large nuclear builds.
Approximately 90% of each Rolls‑Royce SMR unit will be manufactured in factory conditions before being transported for assembly, enabling repeatable, standardised deployment in diverse environments.
Retaining a 470 MWe output and a service life of at least 60 years, each reactor provides reliable baseload power while benefiting from modern engineering enhancements, including innovative seismic protection systems under development in partnership with engineering specialists such as Skanska.
For the nuclear workforce, supply chain partners, and future entrants into the sector, this collaboration signals the emergence of a new industrial era. The programme will expand opportunities in advanced manufacturing, civil engineering, regulatory oversight, systems integration, digital design, and project management, fields that will underpin SMR deployment for decades to come.
As the UK and Czech Republic begin to realise their first SMR projects, the Rolls‑Royce SMR–Amentum partnership is not only reshaping the energy landscape but also redefining the scale of opportunity available to the nuclear profession.
This alliance demonstrates the powerful role that SMRs can play in strengthening energy resilience, supporting decarbonisation, and revitalising nuclear capability across Europe.
With delivery partners now aligned and early development milestones underway, the stage is firmly set for a new chapter in nuclear innovation, one driven by collaboration, standardisation, and a shared commitment to a clean‑energy future.
