NRC Proposes to End ALARA Radiation-Safety Principle Amid Trump’s Nuclear Expansion Drive

NRC Proposal to End ALARA
The Nuclear Regulatory Commission (NRC) has issued a draft rule that would replace the “as low as reasonably achievable” (ALARA) principle—used for five decades to keep radiation exposures well below dose limits—with a graded-approach framework. The agency says dose limits for workers (5 rem/5,000 millirem per year) and the public (100 millirem per year) remain unchanged, but the new rule would require more rigorous protection actions only when exposures approach those caps.
Policy Context and Trump Administration Goals
The proposal arrives as President Donald Trump seeks to quadruple domestic nuclear electricity generation to meet rising demand from data-center and artificial-intelligence growth. In an executive order last year, Trump directed the NRC to “adopt science-based radiation limits.” The Energy Department has already stopped using ALARA, and the NRC expects to finalize the new regulations in the coming months.
Responses from Regulators and Industry
NRC Chairman Ho Nieh told reporters that the change does not lower safety standards, describing it as “removing the ambiguity” while keeping exposure limits intact. He added that the rule is unlikely to affect the existing fleet of large reactors but could accelerate development of smaller, advanced designs. Doug True, chief nuclear officer at the Nuclear Energy Institute, affirmed the industry’s stance: “We will always continue to look at what can we do to reduce the dose to workers, and maintain our doses to the off-site public as low as possible,” — Doug True, chief nuclear officer at the Nuclear Energy Institute He emphasized that the sector will continue to seek ways to reduce worker doses and keep public exposure “as low as possible.”
Expert and Public-Health Concerns
Edwin Lyman, director of nuclear-power safety at the Union of Concerned Scientists, warned that eliminating ALARA could allow permissible public doses to rise from 10 millirem to 25 millirem per year in certain modeling scenarios, even though the overall cap stays at 100 millirem. Katy Huff, former U.S. assistant secretary for nuclear energy and professor at the University of Wisconsin-Madison, noted that ALARA already permits trade-offs and that clarification—not removal—might better serve safety. Kathryn Higley, president of the National Council on Radiation Protection and Measurements, highlighted that the current occupational limit of 5 rem exceeds the International Commission on Radiological Protection’s recommended average of 2 rem, suggesting alignment with international standards may become necessary.
