Rolls-Royce SMR’s nuclear power plant design is entering the Generic Design Assessment (GDA) process with its regulators – the Office for Nuclear Regulation, the Environment Agency and Natural Resources Wales. 

This is the most significant step so far in securing consent for the Small Modular Reactor design to operate in the UK and follows successful completion of the Department for Business Energy and Industrial Strategy’s initial screening process.

Rolls-Royce SMR CEO, Tom Samson, said: “Entering the GDA assessment process is another major milestone as we head at pace towards our goal of deploying a fleet of SMRs which will produce affordable, low carbon electricity – helping meet future energy demands and reach our net zero targets.

“The UK regulatory process is internationally recognised and respected. We welcome the scrutiny and challenge that goes into the assessment of our nuclear power plant design.”

The 470MW SMR draws upon the established pressurised water reactor (PWR) technology in use all over the world, but Rolls-Royce SMR’s approach will see the reactor components built in factory conditions and assembled on site. 

Helena Perry, Regulatory and Safety Affairs Director, added: "Rolls-Royce SMR has a dedicated team with previous experience in GDA, licensing and permitting. We have a collaborative relationship with the UK regulators and are using all our experience and learning to move at pace through the GDA process."
