In early July 2026 the Nuclear Regulatory Commission announced two linked reforms: it replaced the long‑standing ALARA radiation‑protection principle with fixed public dose limits of 25 mrem yr⁻¹ (while retaining the 100 mrem cap) and narrowed the scope of NEPA reviews for new and renewal reactor licences, expanding categorical exclusions and projecting a $135 million savings for applicants and the agency. The changes kept the linear no‑threshold model and were described by Chairman Ho Nieh as “what NEPA demands, nothing more, nothing less.” Later that month the NRC staff recommended a construction permit for the TVA’s 300‑MW BWRX‑300 SMR at Clinch River, moving the project toward physical construction pending final commissioner approval. On 26 July 2026 the NRC released a proposal to eliminate the ALARA principle entirely, principle, substituting a graded‑approach framework that ties regulatory actions to potential dose levels while leaving existing maximum dose limits unchanged. The agency said the move would simplify compliance, especially for small‑modular reactors, and would align with President Trump’s push to expand domestic nuclear capacity. A final rule is expected in the coming months, with the NRC asserting no major impact on the existing fleet of large reactors. The proposal is reinforced by an executive order from President Trump calling for a fourfold increase in U.S. nuclear generation to meet rising electricity demand from data‑center and AI workloads. The Energy Department has already stopped using ALARA, underscoring broader policy coordination. Critics continue to warn that removing ALARA could increase cancer risk for nearby communities, while the agency maintains that safety standards remain unchanged.
