NRC Proposes to Replace Long-Standing ALARA Radiation Rule with a “Graded Approach”

Core Proposal and Timeline
On July 15, the U.S. Nuclear Regulatory Commission (NRC) published a rule change in the Federal Register that would eliminate the “as low as reasonably achievable” (ALARA) principle that has guided radiation protection for more than five decades. The agency plans to replace ALARA with a “graded approach,” which would tailor safety measures to the expected level of exposure while keeping the statutory dose limits for workers and the public unchanged. The NRC expects to finalize the rule in the coming months.
Background and Context
ALARA requires nuclear plants, hospitals, universities and other facilities that use radioactive materials to reduce exposure below legal limits whenever technically and economically feasible. The Trump administration, citing a May 2025 series of executive orders aimed at expanding U.S. nuclear power, argues that ALARA has become overly subjective and imposes unnecessary costs. Proponents say the new framework will speed the licensing of smaller reactors and support the broader goal of meeting rising electricity demand, especially from artificial-intelligence data centers.
Official Statements & Responses
NRC Chairman Ho Nieh told reporters the change is intended to “remove ambiguity” rather than weaken safety standards. He emphasized that the legal exposure limits—100 millirem per year for the public and 5,000 millirem per year for adult workers—remain the same, and that the rule should not affect large, traditional reactors but could aid developers of new, smaller reactors.
Data & Statistics
The proposal would allow a radionuclide emissions standard to rise from 10 millirem to 25 millirem annually, still below the overall public exposure cap of 100 millirem per year. Worker limits would stay at 5,000 millirem per year. These figures illustrate the quantitative scope of the regulatory shift.
