It ensures that the designs meet safety, security and environmental protection requirements throughout their lifecycle, from construction to decommissioning.

Rolls-Royce’s SMR now moves into the third and final phase.

Rolls-Royce SMR’s progression to Step 3, the detailed assessment, marks a significant home advantage as it is set to become the first new nuclear power station designed and constructed in the UK in over a generation.

Each factory-built nuclear power station is designed to generate affordable, low-carbon electricity sufficient to power one million homes for 60 years.

The Rolls-Royce SMR is a part of the Great British Nuclear SMR technology selection process, which is currently underway.

Rolls-Royce SMR’s safety and regulatory affairs director Helena Perry stated: “The completion of Step 2 of the GDA is the most important milestone to date in advancing deployment of Rolls-Royce SMRs in the UK.

“We have built fantastic momentum, and the team will move directly into Step 3 of this rigorous independent assessment of our technology – ideally positioning us to deliver low-carbon nuclear power and support the UK transition to net zero.”

In May 2024, Rolls-Royce partnered with the University of Sheffield to create a new manufacturing and testing facility in South Yorkshire, UK.

The Rolls-Royce SMR development facility will be located at the university’s Advanced Manufacturing Research Centre’s (AMRC) Factory 2050.
