Rolls-Royce has submitted its final proposal to Great British Nuclear (GBN) as part of a competitive process to supply small modular reactors (SMRs) for the UK’s future energy infrastructure.
After six months of negotiations, the company is one of four international vendors shortlisted by GBN. If selected, Rolls-Royce’s SMR solution would mark a major step in reshoring nuclear technology, with implications for domestic manufacturing, energy security, and supply chain growth.
The UK-designed SMRs are intended to be factory-built and rapidly deployed, each capable of producing enough low-carbon electricity to power around one million homes for over 60 years. Rolls-Royce argues that the scalable nature of its design and its advanced stage in regulatory review make it a viable option for the UK’s long-term energy strategy.
Rolls-Royce SMR is also gaining traction internationally, having been chosen by Czech utility CEZ to supply up to 3GW of electricity and progressing in a vendor selection process led by Swedish energy group Vattenfall.
Within the UK, the company is currently in the final phase of regulatory assessment, which places it ahead of its competitors in terms of domestic approval.
