The Nuclear Regulatory Commission has taken the next step toward developing fusion regulations, announcing the opening of a 90-day comment period, ending May 27, on a proposed regulatory framework.

In 2023, the NRC commissioners considered three options for the regulatory framework, ultimately selecting to integrate fusion machines into the existing byproduct material approach, which avoids classifying fusion energy systems as utilization facilities. The aim is to implement this approach through changes to 10 CFR Parts 20, 30, 37, 50, 51, 72, 110, 150, 170, and 171.

Palo Verde, with three reactors and a combined capacity of about 4,000 MWe, is the only nuclear power plant in Arizona. But that could very well change soon if state officials have their way.

Much like other states in the West, Arizona believes nuclear energy is a vital component of the state’s future energy portfolio. At a special meeting of the Arizona Corporation Commission on February 24, commissioners, officials, and others in attendance showed broad bipartisan support for expanding nuclear energy.

Constellation has submitted an application with the Nuclear Regulatory Commission requesting three amendments to its renewed facility license to support the potential restart of Crane nuclear power plant (formerly Three Mile Island-1).

The Nuclear Regulatory Commission staff is recommending proposed changes for the Reactor Oversight Process (ROP) baseline inspection program that could reduce the number of hours spent annually on direct inspections at U.S. nuclear power plants by 38 percent.

In addition to the proposed ROP changes, NRC staff published recommendations for the baseline security program that would reduce the number of direct inspection hours necessary for this program by about 50 percent compared to current levels. This includes the Force-on-Force (FOF) inspection program.

The Nuclear Regulatory Commission on Wednesday announced it was discontinuing three rulemaking activities intended to enhance the security of a deep geologic repository and the protection of spent nuclear fuel.

The NRC said that, among other reasons, it has decided not to proceed with the previously proposed rules due to a change in agency priorities resulting from President Trump’s Executive Order (EO) 14300, “Ordering the Reform of the Nuclear Regulatory Commission.”

A Nuclear Regulatory Commission Atomic Safety and Licensing Board (ASLB) will hear arguments on February 26 on challenges to a construction permit application from Long Mott Energy (LME) for a multiunit reactor facility at Dow Chemical Company’s Seadrift site in Calhoun, Texas. LME is a wholly owned subsidiary of Dow.

An opportunity to request an adjudicatory hearing for Duke Energy Carolinas’ early site permit (ESP) application for the Belews Creek site in Stokes County, N.C., has been announced by the Nuclear Regulatory Commission. The notice of the opportunity was published February 9 in the Federal Register. The deadline to file a request for a hearing or petition for leave to intervene is April 10, 2026.

The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) has held another presentation in its monthly Community of Practice (CoP) series. Former RP3C chair N. Prasad Kadambi opened the meeting with brief introductory remarks about the RP3C and the need for new approaches to nuclear design that go beyond conventional and deterministic methods. He then welcomed this month’s speaker: Dan Moneghan from the Electric Power Research Institute, who presented “Characterization vs. Qualification: A Pathway to Liquid Fuel Licensing."

The Nuclear Regulatory Commission announced yesterday that it is launching a significant reorganization to streamline decision making, consolidate functions, and align with national goals for more efficient licensing and deployment of new nuclear technology.

The changes are intended to meet the requirements outlined in President Trump’s Executive Order 14300, “Ordering Reform of the Nuclear Regulatory Commission,” and EO 14210, “Implementing the Department of Government Efficiency Workforce Optimization Initiative.”

A recent $3.5 million philanthropic commitment from the Bezos Earth Fund to the Nuclear Scaling Initiative has put a spotlight on the organization. As the NSI enters its third year with a new cash infusion, now is the perfect time to explore its history, mission, and progress so far.

The Department of Energy has announced that it is establishing a categorical exclusion for the application of National Environmental Policy Act (NEPA) procedures to the authorization, siting, construction, operation, reauthorization, and decommissioning of advanced nuclear reactors.

According to the DOE, this significant change, which goes into effect today, “is based on the experience of DOE and other federal agencies, current technologies, regulatory requirements, and accepted industry practice.”

Two participants in the Department of Energy’s Reactor Pilot Program have recently announced significant milestones on their associated reactor projects. Aalo Atomics successfully completed its final design review (FDR), and Antares Nuclear has received DOE approval of its preliminary documented safety analysis (PDSA).

Katy Huff, former assistant secretary of nuclear energy at the Department of Energy, recently wrote an op-ed that was published in Scientific American.

In the piece, Huff, who is an ANS member and an associate professor in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois–Urbana-Champaign, argues that weakening Nuclear Regulatory Commission radiation regulations without new research-based evidence will fail to speed up nuclear energy development and could have negative consequences.

Utah-based EnergySolutions announced on January 15 that it has submitted a notice of intent to the Nuclear Regulatory Commission, confirming that the company plans to submit an application for a “major licensing action” for new nuclear generation at the closed Kewaunee nuclear power plant in Wisconsin. Applications for an early site permit, construction permit, or combined license are currently being evaluated, the company said.

Today, a bipartisan group of experts including energy consultant Lake Barrett and former NRC chair Allison Macfarlane have published a report titled The Path Forward for Nuclear Waste in the U.S.

The report recommends a new solution for managing domestic nuclear waste—one that centers around the foundation of an independent corporation led by reactor owners. Responsibility for waste management transport, storage, and disposal would be managed by this corporation rather than the Department of Energy.

Tech giant Meta is making big bets on TerraPower and Oklo. With the former, the hyperscaler could support the deployment of up to eight new reactors. With the latter, it could be as many as sixteen.

For both start-ups, Meta hopes its demand bolsters supply chains, the workforce, and the nuclear industry generally. For itself, the company is aiming to secure more generation to cleanly power its AI ambitions.

The U.S. Supreme Court has denied a petition by antinuclear group Beyond Nuclear challenging the Nuclear Regulatory Commission’s licensing of Holtec International’s proposed consolidated interim storage facility (CISF) for spent nuclear fuel in New Mexico.

The denial of Beyond Nuclear’s writ of certiorari petition was part of a long list of orders released by the Supreme Court on Monday. The list also included a denial of Duke Energy’s appeal of a lower court’s ruling in an antimonopoly dispute.

Thursday was a busy news day for the Nuclear Regulatory Commission, with three significant announcements.

In the span of a few hours, the NRC released the news of Ho Nieh’s promotion to chair, the reversal of the plan to sunset its aircraft impact assessment provisions, and new guidance for interagency collaboration.

The U.S. House Energy and Commerce Subcommittee on Energy convened its first hearing of the year, “American Energy Dominance: Dawn of the New Nuclear Era,” on January 7, where lawmakers and industry leaders discussed how nuclear energy can help meet surging electricity demand driven by artificial intelligence, data centers, advanced manufacturing, and national security needs.

This week, the Department of Energy has finalized two new other transaction agreements (OTAs) with participating companies in its Reactor Pilot Program, which aims to get one or two fast-tracked reactors on line by July 4 of this year. Those companies are Terrestrial Energy and Oklo.
