The United Kingdom has selected Rolls-Royce SMR as the preferred technology provider for its ambitious Small Modular Reactor (SMR) program, signaling a significant step towards a "new golden age of nuclear" in the country. This decision, announced by Great British Nuclear (GBN), will see a British company design and build the nation’s next generation of nuclear power stations.
Key Takeaways
- Rolls-Royce SMR chosen as preferred technology provider by Great British Nuclear.
- UK government pledges over £2.5 billion for the SMR program.
- Project aims to create thousands of skilled jobs and power approximately 3 million homes.
- First SMR plants are targeted for in-service dates in the mid-2030s.
A New Era for British Nuclear Power
The UK government’s selection of Rolls-Royce SMR marks a pivotal moment, with an investment of over £2.5 billion earmarked for the overall SMR program. This initiative is projected to generate thousands of high-skilled, well-paid jobs and stimulate opportunities within the domestic supply chain. Rolls-Royce SMR’s chief executive, Chris Cholerton, expressed enthusiasm, stating that the deployment of three of their units will drive significant domestic growth.
The Selection Process and Technology
Great British Nuclear (GBN) made the decision following a rigorous two-year international selection process. In February 2025, GBN had invited four companies to submit final tenders: GE-Hitachi Nuclear Energy International, Holtec Britain, Rolls-Royce SMR, and Westinghouse Electric Company UK. Rolls-Royce’s SMR technology features factory-built components, which are designed to enhance transportation ease, reduce construction risks, and improve schedule certainty. Each plant will have an output capacity of 470 MW.
Future Plans and Global Context
GBN is expected to finalize contracts with Rolls-Royce SMR later this year, with site allocation also anticipated within the same timeframe. The government aims for the first SMR plants to be operational by the mid-2030s. Rolls-Royce is also engaged in similar SMR projects internationally, including a deal with Czech utility ČEZ and a finalist position in Sweden’s SMR competition. Experts note the importance of swift action, given the increasing global competition in SMR development, with countries like the US making substantial investments in the technology. This development follows closely on the heels of a £14.2 billion investment announced for the Sizewell C nuclear power station project.
