Rolls-Royce’s small modular reactor (SMR) has successfully cleared the second stage of a crucial regulatory process in the UK.
- The design is now set to undergo a detailed assessment by UK nuclear regulators.
- This marks a significant milestone for the deployment of SMRs as part of the UK’s net-zero strategy.
- Various UK agencies are collaborating to ensure the reactor meets stringent safety and environmental standards.
- The third phase will determine final approval, focusing on safety, security, and environmental compliance.
The Rolls-Royce small modular reactor (SMR) design has achieved a notable milestone by completing the second step of the UK’s regulatory assessment process. This progression paves the way for a more rigorous evaluation of the reactor’s design as it enters the detailed assessment phase, conducted by key regulatory bodies including the Office for Nuclear Regulation (ONR), the Environment Agency, and Natural Resources Wales (NRW).
The design’s journey through the regulatory framework began in April 2022, marked by a structured process known as the generic design assessment (GDA). Initially, a year-long initiation phase was carried out, laying the groundwork for a subsequent 16-month period that thoroughly examined the design’s fundamental aspects. The completion of the second stage signifies the issuance of step two GDA statements, a first since the inception of this enhanced assessment process.
Helena Perry, the safety and regulatory affairs director at Rolls-Royce SMR, highlighted the importance of this achievement, stating, “The completion of step two of the GDA is the most important milestone to date in advancing deployment of Rolls-Royce SMRs in the UK.” This forward momentum is, according to Perry, crucial in facilitating the delivery of low-carbon nuclear power, thus supporting the UK’s transition to a net-zero future.
Rob Exley, leading the generic design assessment at ONR, reflected on this pioneering initiative, explaining that this assessment is groundbreaking both for its subject matter and methodology. “The Rolls-Royce SMR GDA is one of firsts,” Exley said. He emphasised the modernised nature of the process that places a spotlight on small modular reactors, ensuring they meet robust safety and environmental standards.
Moving forward, the design will undergo more stringent evaluations in the third and final GDA phase. This stage will focus extensively on validating the claims made concerning the design’s safety, security, and environmental impact. Only upon satisfactory completion of this step will a design acceptance confirmation or a statement of design acceptability be issued, ensuring the design aligns with regulatory expectations and supports the UK’s broader energy goals.
The ultimate approval of the Rolls-Royce SMR design remains contingent upon its successful navigation through the rigorous third phase of assessment.
