The Office for Nuclear Regulation (ONR) and the Environment Agency (EA) have published their responses to Chancellor of the Exchequer John Healey, detailing how they intend to expedite nuclear project delivery throughout the United Kingdom. These actions follow the Nuclear Regulatory Taskforce's November report, which proposed 47 recommendations for the government to reduce the cost and time required for new nuclear projects. The taskforce, established in February 2025 by then Prime Minister Keir Starmer and led by John Fingleton, aimed to accelerate new reactor design approvals and simplify developer engagement with regulators.
ONR CEO and Chief Nuclear Inspector Mike Finnerty described the regulator's transformation to align with a growing nuclear sector while upholding safety, security, and safeguards standards. A key component of this transformation is "ONR Together," a new strategy designed to foster a more modern, agile, and productive organization. Initiatives include forming a Lead Nuclear Regulator Group to enhance coordination and an Industry CEO Forum to address delays. The ONR has also updated safety case guidance to promote clearer and more proportionate safety arguments and is reviewing regulatory processes to streamline decision-making.
The ONR is modernizing its assessment of new reactor designs, adopting a more flexible approach within Generic Design Assessment programs, and developing fleet-based regulatory models for various reactor technologies. The regulator supports government proposals for a Commission for Nuclear Regulation and reforms to its charging model, alongside expanding international collaboration for mutual learning and efficient deployment of proven nuclear technologies. Finnerty emphasized nuclear's critical role in the United Kingdom's energy future, highlighting the need for collaboration among industry, government, and regulators to ensure safe and timely project deployment.
The Environment Agency expressed full support for improving the pace, predictability, and proportionality of nuclear regulation while maintaining environmental protection and public confidence. The agency has established a Nuclear Transformation Programme to coordinate the implementation of the review's recommendations, particularly those related to organizational effectiveness, culture, proportionality, and regulatory coordination. The Environment Agency has consolidated its nuclear strategy and regulatory functions under a single leadership structure, reporting to the Chief Regulator, to enhance accountability, decision-making, and strategic oversight. The agency noted that securing sufficient nuclear expertise is crucial for delivering these reforms alongside existing regulatory responsibilities.
