As announced on 13 November, the Great British Energy – Nuclear (GBE-N) small modular reactor (SMR) project will be sited at Wylfa on Anglesey in North Wales, supporting around 3,000 good jobs at peak construction and thousands more across the supply chain.

Subject to final government approvals and contract signature, the project will deploy Rolls-Royce SMR technology. Ahead of contract signature, it is not possible to comment on specific SMR components or supply chain, though GBE-N's ambition is to deliver over 70% UK content across the SMR fleet.
