Overview
- The Nuclear Regulatory Commission proposed the change on Wednesday, July 1, and opened a 45‑day public comment period before any rule can be finalized.
- The proposal would eliminate the ALARA principle—“as low as reasonably achievable”—and let licensees use a graded, risk‑informed approach and modern dose‑evaluation methods.
- NRC Chair Ho Nieh said the rule aims to clarify requirements without lowering safety standards and that existing reactors likely would not need major changes.
- Industry supporters say ALARA is tied to the Linear No‑Threshold model and creates costly uncertainty, while critics such as the Union of Concerned Scientists warn the change could permit higher worker and public radiation exposures.
- The move is part of a wider push from the White House and the NRC to speed reactor permitting and licensing for new designs, and the outcome will depend on the public comment record and further agency rulemaking.
