With DOME’s opening, microreactor developers will soon be able to test, demonstrate, and validate their reactor designs. Rian Bahran, the Department of Energy’s deputy assistant secretary for nuclear reactors, called this “essential infrastructure” a “testament to our commitment to a robust nuclear future” and a key tool for “accelerating the development and deployment” of new energy technologies.

New Jersey has become the latest state to lift a moratorium on the construction of new nuclear power plants, with Gov. Mikie Sherrill signing new legislation Wednesday with the state’s two nuclear power plants serving as the backdrop.

The legislation, S. 3870/A. 4528, allows the commissioner of the state’s Department of Environmental Protection to approve permits for the construction and operation of new nuclear facilities “based on safe, [Nuclear Regulatory Commission]–compliant waste storage.” Prior to this bill, New Jersey law practically banned such construction, because the state’s Coastal Area Facility Review Act required an approved method from the NRC for radioactive waste disposal that was outdated and could not be met.

The agency said it has invested approximately $134 million in commercial fusion since it began funding fusion projects with the launch of its ALPHA program in 2014, so the next year and a half will see a doubling of the agency’s investment in the fusion space.

The commissioners on Friday approved an overhaul of the security program, including phasing out NRC-led drills by 2028. Following the phaseout, drills will be led by the licensee, with the NRC observing.

The final rule, which was published in the Federal Register on Wednesday, addressed some of the more contentious concerns raised by the public. It sets a conditional sunset date of April 8, 2027, “unless the NRC determines that the cessation deadline should be extended to a date not more than 5 years in the future after offering the public an opportunity to provide input on the costs and benefits of this section and considering that input.”

Included in those recommendations were the foundation of a nonregulatory entity to coordinate Texas’s “strategic nuclear vision” along with an advanced nuclear fund to help “overcome the funding valley project developers face” in the state.

The request from the Trump administration is one of several associated with nuclear energy in the proposal, which was released Friday. Congress still must review and vote on the budget.

This long-expected submittal builds on previous plans at both the NRC and Westinghouse for the future of gigawatt-scale light water reactor deployments in the United States.

A proposed rule introduced April 2 by the NRC would “improve NRC licensing review efficiency, where applicable, by explicitly establishing by regulation an additional means for reactor applicants to demonstrate the safety functions of their reactor designs, and thus, would contribute to the safe and secure use and deployment of civilian nuclear energy technologies.”

This press release comes as the ongoing conflict in the Middle East primarily involving Iran, Israel, and the United States continues to rapidly evolve and intensify. As is the case with many armed conflicts, the confirmation of each reported update from multiple—and often contradictory—sources comes with significant difficulties. However, IAEA reporting sheds significant light on the current state of Iran’s nuclear facilities.

The region’s governors, though, may seek to expand these numbers. The governors of Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont issued a joint statement in support of exploring next-generation nuclear energy technologies. The bipartisan announcement also urges continued support for local nuclear facilities like Millstone and Seabrook.

“The American Nuclear Society supports the International Atomic Energy Agency's (IAEA) calls for maximum military restraint around nuclear power plants and civilian research reactors, and for full adherence by all combatants to the IAEA's seven pillars for nuclear safety and security during armed conflict.”

Thursday’s approval means Diablo Canyon-1 and -2 can now operate until November 2, 2044, and August 26, 2045, respectively, if California lawmakers agree. A 2022 state law requires the California Legislature to approve any extension of operations at Diablo Canyon that goes beyond 2030.

Among the items that emerged on Constellation and the Crane restart in Middletown, Pa., during last week’s CERAWeek energy conference was a Reuters report on an analysis from electric grid provider PJM suggesting the plant may not be connected to the grid until 2031.

The team chose to engage with the NRC in a preapplication readiness assessment, providing the agency with draft versions of the majority of the CPA’s technical content for feedback, which is expected to ensure a high-quality application.

The 208-page document was created by the AI tool in approximately one day. According to the DOE, it would typically take a team of people between four and six weeks to complete this work.

The restart of Palisades nuclear power plant in Covert, Mich., has hit a milestone with the passivation of its primary system, plant owner Holtec International announced Monday, even as a firm restart date has yet to be announced.

Passivation is a chemical process that improves corrosion resistance by making plant materials less reactive. During the process, the reactor’s primary system was brought to normal operating temperature and pressure. Holtec called this passivation phase an “essential step” in maintaining the long-term reliability of equipment.

Yasir Arafat, chief technical officer of Aalo Atomics; Jordan Bramble, CEO of Antares Nuclear; and Rita Baranwal, chief nuclear officer of Radiant Industries, participated in the discussion and covered their recent progress in the Department of Energy’s Reactor Pilot Program. Nader Satvat, director of nuclear systems design at Kairos Power, gave an update on the company’s ongoing demonstration projects taking place outside of the landscape of DOE authorization.

The Houston- and McLean, Va.–based company plans to convert uranium oxide into uranium hexafluoride (UF₆), a critical intermediate step in producing fuel for the nation’s existing nuclear reactors as well as next-generation technologies under development.

These revisions are included in the final rule, “Categorical exclusions from environmental review,” which was published in the Federal Register on March 30. The final rule will become effective on April 29.

DOE-EM’s efforts to manage waste resulting from legacy spent nuclear fuel reprocessing have been hindered for decades by the ambiguity of the statutory definition of HLW as laid out in the Atomic Energy Act and Nuclear Waste Policy Act, the report states. While admitting that the DOE has taken steps to overcome this ambiguity, the GAO says that the department has not fully evaluated all available opportunities to treat and dispose of waste more economically as either transuranic or low-level radioactive waste.

The American Nuclear Society’s Risk-informed, Performance-based Principles and Policy Committee (RP3C) held another presentation in its monthly Community of Practice (CoP) series last month. RP3C chair Steven Krahn opened the meeting with brief introductory remarks about the importance of risk-informed, performance based (RIPB) decision-making and the need for new approaches to nuclear design that go beyond conventional and deterministic methods.

This adoption comes just over a month after NRC officials published their findings on the proposed ROP changes. The changes would reduce the number of hours spent annually on direct inspections at U.S. nuclear power plants by 38 percent.

In addition, the Nuclear Regulatory Commission, in cooperation with the U.S. Army Corps of Engineers, has completed a draft environmental impact statement (EIS) in response to GLE’s application to construct and operate the PLEF. Members of the public can submit comments on the draft EIS by May 11 for consideration by the NRC.

The request for information posted Wednesday intends to assist the federal government in identifying potential developers and “understanding the company’s capability to design, license, fuel, construct, and deploy Small, Micro, or Modular Reactor (SMR) technologies in compliance with applicable regulatory, safety, environmental, and security requirements.”

Microsoft said in an announcement that the collaboration will build a “connected, AI-powered foundation” of AI tools that energy developers will be able to use to make work “repeatable, traceable, secure, and predictable,” all the while reducing work timelines and maintaining safety.

Radiation-induced modifications are widely applicable across a range of fields including healthcare, agriculture, and environmental applications, and exposure to radiation is a major factor when considering materials used at nuclear power plants.
