The Nuclear Regulatory Commission is considering allowing Entergy to use a portion of the decommissioning trust fund (DTF) for the Arkansas Nuclear One nuclear power plant to dispose of several major radioactive components (MRC) that have been taken out of service at the two-unit pressurized water reactor.

So, President Trump has just kicked the low-dose radiation hornets’ nest.

Specifically, his recently signed executive order “Ordering the Reform of the Nuclear Regulatory Commission” calls for the NRC to “reconsider reliance” on the linear no-threshold (LNT) theory and the ALARA (as low as reasonably achievable) standard for radiation protection.

This directive will certainly reignite a vociferous debate within the radiation research community over the continued efficacy of using LNT as the basis for protecting the public and the environment, a community that has been wracked with controversy on this matter for the last few years.

I must admit that whenever the low-dose issue comes up, my first thoughts always go to Sayre’s Law.

Texas-based Vistra Corporation has announced that its license renewal application for the Perry nuclear power plant was approved by the Nuclear Regulatory Commission. The plant first connected to the grid in 1986 and is still operating under its original 40-year license, which was set to expire next year.

The Nuclear Regulatory Commission has whittled down the timeline for reviewing TerraPower’s construction permit application for Kemmerer Power Station Unit 1 in Wyoming. Announcing a new, more aggressive schedule, the NRC said it aims to complete its review by the end of 2025, eight months earlier than originally planned.

Global Laser Enrichment announced that it has submitted its safety analysis report to the Nuclear Regulatory Commission for the planned Paducah Laser Enrichment Facility (PLEF). This follows GLE’s December 2024 submission of the plant’s environmental report, now completing GLE’s full license application for NRC review.

Dominion Energy’s V.C. Summer nuclear power plant, in Jenkinsville, S.C., has been authorized to operate for 80 years, until August 2062, following the renewal of its operating license by the Nuclear Regulatory Commission for a second time.

Wright

The Nuclear Regulatory Commission is in the spotlight today for three very different reasons. First, NRC Chair David Wright was on Capitol Hill yesterday for his renomination hearing in front of the Senate’s Environment and Public Works Committee. Second, the NRC released its updated milestone schedules according to the Nuclear Energy Innovation and Modernization Act (NEIMA) and the executive orders signed by President Trump last month; and third, as reported by Reuters on Tuesday, 28 former NRC officials have condemned the dismissal of Commissioner Hanson earlier this month.

Renomination: EPW Committee chair Sen. Shelley Moore Capito (R., W.Va.) opened the hearing with a statement praising Wright’s experience and emphasized the urgency of stable leadership at the NRC.

“China is executing a rapid build-out of its nuclear industry,” Capito said. “The demand for clean, baseload power is skyrocketing as we position America to win the AI race.”

The Nuclear Regulatory Commission has announced it has amended regulations for the licensing, inspection, special projects, and annual fees it will charge applicants and licensees for fiscal year 2025.

Paragon Energy Solutions has signed a memorandum of understanding with Terra Innovatum, a developer of micro-modular nuclear reactors, to support the design and integration of instrumentation and control systems for Terra’s Solo micro-modular reactor. Paragon is a provider of safety-related I&C systems for the nuclear energy community.

Details of the plan to test new reactor concepts under the Department of Energy’s authority but outside national laboratory boundaries—first outlined in one of the four executive orders on nuclear energy released on May 23—were just released in a request for applications issued by the DOE.

The Supreme Court voted 6–3 against Texas and a group of landowners today in a case involving the Nuclear Regulatory Commission’s licensing of a consolidated interim storage facility for spent nuclear fuel, reversing a decision by the 5th Circuit Court of Appeals to grant the state and landowners Fasken Land and Minerals (Fasken) standing to challenge the license.

Hanson

Since the president's inauguration in January, the Trump administration has been on course to make big changes at the Nuclear Regulatory Commission to realize its goals of deregulation, energy dominance, and deployment of advanced reactors. Given the executive orders (EOs) and the work that the Department of Government Efficiency has done in cutting the federal workforce, it was a surprise that NRC commissioner Christopher Hanson was dismissed on Friday, according to a statement Hanson posted on his LinkedIn profile early Monday.

Hanson said in the post that President Trump terminated his position “without cause, contrary to existing law and long-standing precedent regarding removal of independent agency appointments.”

The U.S. Department of Air Force has announced its notice of intent to award advanced nuclear technology company Oklo a contract to pilot a microreactor at Eielson Air Force Base in Alaska.

The Nuclear Regulatory Commission is providing the opportunity to request a hearing on Dow Chemical Company’s application to construct a 320-MWe nuclear power plant at the company’s Seadrift site in Calhoun, Texas. Long Mott Energy, a wholly owned subsidiary of Dow Chemical, submitted its construction permit application to the NRC in March. It was accepted for review by the agency on May 12.

In the weeks since President Donald Trump issued four nuclear energy–-focused executive orders (EOs), stakeholders across the nuclear industry weighed in on the plans and details. The American Nuclear Society convened an expert advisory group to study the directives and provide constructive input for the pending implementation.

A group of nine former commissioners of the Nuclear Regulatory Commission sent a letter Wednesday to the chairs and ranking members of the Senate Environment and Public Works Committee and the House Energy and Commerce Committee, lending their support to efforts to remove mandatory hearings from the reactor licensing process. The move could speed up the new reactor licensing process by about three to six months and save millions of dollars.

The Nuclear Regulatory Commission is conducting a special inspection at Constellation’s Quad Cities nuclear plant to review two events caused by battery issues. Neither event had any impact on public health or plant workers.

Meta is teaming up with Constellation to buy nuclear power from an Illinois plant over the next 20 years in a power purchase agreement that helps support the goals of both companies.

Oklo announced last week that it hopes to expand development and global deployment of its advanced nuclear technology through a new partnership with Korea Hydro & Nuclear Power.

The memorandum of understanding includes plans for the companies to advance standard design development and global deployment of Oklo’s planned Aurora Powerhouse, a microreactor that would generate 15 MW and be scalable to 50 MWe. Oklo said each unit can operate for 10 years or longer before refueling.

Oklo and KHNP plan to cooperate on early-stage project development, including manufacturability assessments and planning of major equipment, supply chain development for balance-of-plant systems, and constructability assessments and planning.

NuScale earned approval for its “larger” US460 77-MWe small modular reactor plant design, the Nuclear Regulatory Commission announced last week.

The standard design approval (SDA) is a determination by NRC staff that a reactor design meets the agency’s applicable design requirements, and companies can reference it when applying for a license to build and operate the reactor—but it does not ensure license approval from the commission.
