The Rolls-Royce SMR, also known as the UK SMR,[1] is a small modular reactor (SMR) design being developed by the Rolls-Royce (RR) company in the United Kingdom.
The company has been given financial support by the UK Government to develop its design. In 2019 it was estimated that the 470 MWe units would cost around £1.8 billion once in full production, compared with £22 billion for a full-sized nuclear power station such as the planned 3,300 MWe Sizewell C. Construction time and site size needed would also be lower.
