The Nuclear Decommissioning Authority Group has submitted a response to the Chancellor’s nuclear regulatory review, drawing on work across the NDA and its operating companies: Sellafield Ltd, Nuclear Restoration Services, Nuclear Waste Services and Nuclear Transport Solutions. Its programme has two elements: immediate improvements within the existing legal and regulatory framework, and a more fundamental reset to be developed with Government, regulators and the supply chain. The response summarises commitments across the five areas identified in the Chancellor’s letter and is accompanied by a submission containing supporting detail and case studies. It complements the Environment Agency’s Nuclear Transformation Programme, which aims to make nuclear regulation faster, more predictable and proportionate while maintaining environmental protection and public confidence. The agency has reported a three-year low in permitting queue times, a backlog reduction of more than three-quarters and complex application decisions up to 100 days faster. Proposed Generic Design Assessment changes could reduce assessment times by up to 50%, while decommissioning reforms are expected to save taxpayers around £500 million over 20 years.
