Why the US must protect the independence of its nuclear regulator

The White House has introduced radical changes that threaten to disrupt the effectiveness of the US Nuclear Regulatory Commission (NRC). The agency was formed in 1975 to be an independent regulator, separating it from the promotional role pursued by its predecessor, the Atomic Energy Commission. The NRC has set safety requirements that have become the global gold standard for nuclear regulation. The White House actions threaten to undermine this record.

Conversations with fellow former NRC chairs and retired NRC experts reveal a shared concern that the changes will have unintended, dangerous consequences. In February, the White House issued an executive order that intruded on the traditional autonomy of independent agencies, thereby giving the White House the capacity to control NRC regulatory actions and allow politics to infect regulatory decision-making. A series of executive orders on nuclear matters issued in late May compounded the challenge. One of the executive orders focuses on the reform of the NRC. It would establish arbitrary deadlines for decisions on construction permits and operating licenses, regardless of whether the design offers new and previously unevaluated safety challenges. Other provisions demand the review of all the extensive NRC regulations within 18 months. The other executive orders allow the construction of nuclear power reactors on federal lands—sites belonging to the Energy Department and the Defense Department—without any review by the NRC.

Then, on June 13, the Trump administration fired Christopher Hanson, an NRC commissioner and former chair, without any stated justification. These actions all serve to weaken protections for those who work in or live near reactors. Given the anticipated expansion of reliance on nuclear power, the drastic staff reductions contemplated by the White House come at the wrong time.

There is always room to assess the efficiency and effectiveness of the regulatory process and adapt it to the evolution of nuclear technologies and their implementation. Recognizing that, past and current NRC commissioners and technical staff have set in motion changes to reduce the regulatory burden and speed the deployment of reactors at a lower cost. The changes are prudent and reasonable and support the promise of expanded reliance on nuclear energy. Congress has also encouraged those efforts and further instructed the NRC to make more improvements to the process through the bipartisan ADVANCE Act signed into law in 2024. All of this was underway before the White House interference.

The NRC has protected the health and safety of Americans for 50 years without a single civilian reactor radiation-related death. The lessons of the 1979 Three Mile Island accident have long been woven into the safety regime, and every commercial reactor in the United States is safer today because of major safety steps taken after the destruction of reactors in Japan’s Fukushima Daiichi plant by a massive earthquake and tsunami in 2011.

Since Three Mile Island, the agency has licensed approximately 50 power reactors to operate. It has recently issued construction permits for advanced reactors ahead of schedule. And the NRC has cleared utilities to boost the power of many existing reactors and has licensed them to run longer than originally planned.

We are concerned about the unintended safety consequences that a reduced NRC independence and a schedule-driven regulatory paradigm threaten to bring.

We fear the loss of public confidence that can befall a safety agency when expediency is seen to be given priority. Reducing the NRC’s independence while mixing promotion of nuclear energy and responsibility for safeguarding the public and environment is a recipe for corner-cutting at best and catastrophe at worst.

We are also concerned that such steps could damage the reputation of US reactor vendors worldwide. A design licensed in the United States now carries a stamp of approval that can facilitate licensing elsewhere, including the many countries that plan to embark on a nuclear power program. If it becomes clear that the NRC has been forced to cut corners on safety and operate less transparently, US reactor vendors will be hurt.

The US nuclear industry is helped by the fact that it has a strong independent regulator behind it. The White House’s executive orders may produce the opposite effect from their stated purpose.
