U.S. Nuclear Regulator Proposes Dropping ALARA Radiation Safety Rule

ALARA NRC radiation safety Trump nuclear power

The U.S. Nuclear Regulatory Commission (NRC) has announced a proposal to eliminate the ALARA principle—"as low as reasonably achievable"—which for the past five decades has been the cornerstone of radiation protection in nuclear plants, hospitals and research facilities. The agency would replace ALARA with a "graded approach" that adjusts protective actions based on the potential dose to workers, while keeping existing maximum dose limits unchanged.

The change is linked to President Donald Trump's agenda to quadruple domestic nuclear power output in response to rising electricity demand from data centers and artificial‑intelligence applications. Trump issued an executive order directing the NRC to adopt science‑based radiation limits, and the Energy Department has already stopped using ALARA. NRC Chairman Ho Nieh said the revision does not lower safety standards but merely removes ambiguity, and that the rules are expected to be finalized in the coming months. He noted that the new framework could allow designers of small or modular reactors to proceed more quickly, though some observers caution that without ALARA radiation doses might drift closer to legal limits.
