US Nuclear Power Regulator proposes to change rule protecting people against radiation

The U.S. Nuclear Power Regulator on Wednesday proposed "changes" to a rule that protects people from radiation. This is the latest proposal by the Trump administration to change or soften the rules in order to speed up development and reduce costs for new nuclear reactors.

In 2025, President Donald Trump issued executive orders to accelerate the permitting of nuclear reactors and overhaul the Nuclear Regulatory Commission. He also directed the Energy and Defense departments work together in order to build nuclear power plants on federal lands. Trump wants to quadruple the U.S. nuclear capacity by 2050 in order to meet rising power demand due to data centres, electric vehicles, and crypto-currencies.

Nuclear Regulatory Commission's proposal removes a radiation dose limit standard, ALARA (As Low as?Reasonably Achievable), with objective limits. Ho Nieh said to reporters that the NRC's rulemaking process would increase the clarity of our regulations. "It does not lower the bar for our safety standards."

Industry has long claimed that ALARA was tied to the Linear No-Threshold model, which holds that "any dose of radiation" (no matter how small) can cause cancer. They also claim that ALARA compliance is expensive, time-consuming and filled with uncertainties.

The proposed changes include adopting a graded radiation dose management approach based on operational and risk circumstances. The new regulation also gives nuclear power plant operators more flexibility in using "modern methods of evaluating radiation doses for workers and the general public."

Nieh stated that he did not expect current nuclear reactors to undergo major changes if the new rule is finalized. He said that it could speed up the development of new nuclear reactors.

Nieh, a reporter, said that "now they have a clear picture of how the requirements for radiation protection will look. This will help them design and build their reactor in terms of shielding and materials."

Edwin Lyman is a physicist at the Union of Concerned Scientists and an advocate for nuclear safety. He said that the NRC reaffirmed scientific consensus?that there's no "safe" level of radiation and the cancer risk is proportional with the dose.

The new rule would allow workers at nuclear facilities and the public to be exposed higher levels of radiation that can cause cancer, just to save money for the nuclear industry.

Lyman stated that "this will only increase the burden of disease at a time where cancer rates among young people are already on the rise."

The NRC made a proposal last month to change a rule that would have "dramatically weakened measures" protecting nuclear power plants from terrorist attacks. A new rule, proposed Wednesday, would streamline the construction of reactors and make major changes to the licensing process.

The NRC will accept public comments for 45 days prior to the finalization of the radiation rule.
