The four companies, GE Hitachi, Holtec, Rolls Royce SMR and Westinghouse, have been shortlisted following two rounds of assessment by GBN, the government’s expert nuclear delivery body.
GBN will negotiate with all four before final tenders are submitted, with final decisions to be taken in the spring.
To reach this stage, each of the four designs was subject to a robust analysis. GBN has evaluated each technology, including aspects such as safety, deliverability, and their ability to support development of a fleet of SMRs. GBN considers the designs, each of which is proceeding through the UK’s regulatory process, are viable options for development. Subject to negotiations, GBN consider any one of these designs would be fit to use in the UK nuclear programme.
GBN’s Chair, Simon Bowen said, ‘This is a significant moment for the SMR programme. Our technical experts have assessed each design in detail and are very confident these SMRs could play a key role in the UK’s future energy mix. The negotiation phase will enable us to select the absolute best technologies on the best terms for the UK.’
