Small Modular Reactors

The question

To ask the Secretary of State for Energy Security and Net Zero, with reference to the press release entitled Rolls-Royce SMR selected to build small modular nuclear reactors, published on 10 June 2025, what estimate he has made of the proportion of reactors that will be produced in the UK.

Answered by Michael Shanks

Following a robust procurement based on fairness and transparency, Great British Energy – Nuclear (GBE-N) has selected Rolls-Royce SMR as its preferred bidder to partner with to deploy the UK's first SMRs, subject to final government approvals and contract signature.

Further details will follow in due course, but the government's long-term ambition is to bring forward one of Europe's first SMR fleets, with GBE-N's ambition being to deliver over 70% UK content across the fleet.
