The Department of the Air Force (DAF) and the Defense Innovation Unit within the Department of Defense have selected Buckley Space Force Base in Colorado and Malmstrom Air Force Base in Montana to potentially site microreactors.

Wednesday’s announcement moves forward the plans of the Advanced Nuclear Power for Installations (ANPI) program, which was launched in 2024 with the objective of deploying “advanced, contractor-owned and operated” microreactors from commercial reactor companies on bases.

Yesterday, the Nuclear Regulatory Commission announced that it has received an application from Westinghouse to renew and update the design certification (DC) for its AP1000 reactor. This application seeks to formally incorporate the lessons learned from the construction of Vogtle-3 and -4 into the design control document (DCD) of the AP1000.

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.

The Nuclear Regulatory Commission has approved Pacific Gas & Electric’s application to extend the operating licenses for Diablo Canyon nuclear power plant’s two pressurized water reactors by another 20 years.

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.

When the former Three Mile Island-1 restarts in 2027 as the Crane Clean Energy Center, it will not face a delay of several years before it can be reconnected to the grid, Constellation CEO Joseph Dominguez said this week.

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.

Polskie Elektrownie Jądrowe, Poland’s state-owned utility, has formally submitted an application for a construction license to build a nuclear power plant at the Lubiatowo-Kopalino site in Pomerania. The country’s first nuclear power plant will consist of three Westinghouse AP1000 units with a total installed capacity of 3,750 MWe. The construction and engineering contractor for the project is a U.S.-based consortium of Westinghouse and Bechtel.

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.

The Nuclear Regulatory Commission has approved a significant overhaul of its Reactor Oversight Process (ROP) baseline inspection program that stresses a leaner, more risk-focused inspection process.

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.

The U.S. Air Force wants to hear from companies that could be interested in deploying small nuclear reactors at its bases.

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 and Nvidia have formed an “AI for nuclear” partnership intended to streamline the permitting, design, and operations of nuclear power plant facilities, and highlighted the collaboration at CERAWeek 2026 in Houston earlier this week.

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.

Coinciding with the March 19 White House meeting between President Trump and Japanese Prime Minister Takaichi Sanae, the Department of Commerce announced three new energy deals as part of a Japan-U.S. Strategic Investment initiative. Two of the deals involve the construction of natural gas generation facilities. The third, with an estimated value of as much as $40 billion, involves the construction of GE Vernova Hitachi (GVH) BWRX-300 small modular reactors in Tennessee and Alabama.

The Nuclear Regulatory Commission has released a notice of intent to conduct a scoping process and prepare an environmental impact statement to evaluate Fermi America’s plan to construct and operate four AP1000 reactors at its Project Matador Advanced Energy and Intelligence Campus in Texas.

While that announcement may seem routine, the process envisioned is not. As part of the company’s combined license (COL) application with the NRC, it has agreed to participate in an accelerated environmental review pilot program under the National Environmental Policy Act (NEPA). Under this pilot, the applicant(s) develop a draft EIS under NRC supervision.

A new report commissioned by the Nuclear Scaling Initiative, conducted by energy consultant Solestiss, and funded by the Bezos Earth Fund identifies and recommends solutions to overcome current bottlenecks in the supply chain for advanced reactors.

Broadly speaking, the report recommends the repeated deployment of Gen III+ reactor designs to rebuild the foundation of domestic manufacturing, workforce, and qualification capacity.

X-energy announced Thursday that it has signed a letter of intent with Talen Energy to assess the deployment of X-energy’s Xe-100 reactor in Pennsylvania and throughout the market area of the PJM Interconnection regional transmission organization. That area, where the companies intend to explore the deployment of at least three four-unit Xe-100 power plants, includes several states in the eastern United States, from New Jersey to Illinois.

Arizona Public Service has informed the Nuclear Regulatory Commission of its intention to renew the operating licenses of the Palo Verde nuclear power plant’s three reactors for a second 20-year term, which could extend operations at the facility into the 2060s.

According to the announcement, APS won’t submit the subsequent license renewal application to the NRC until late 2027. The renewal would allow Unit 1 to operate through 2065, Unit 2 through 2066, and Unit 3 through 2067.

On March 17, Oklo released a series of four press releases in the span of a few hours containing some of the first substantial updates the company has given on its various approval processes with the Department of Energy and Nuclear Regulatory Commission since January.

Specifically, Oklo announced that it has received two nuclear safety design agreement (NSDA) approvals from the DOE and a materials license from the NRC.

At last week’s Regulatory Information Conference, Jamie Pelton cochaired a panel on Palisades nuclear power plant’s restart—a “historic restart,” as she put it.

Her choice of words was perhaps an understatement. After all, no U.S. nuclear plant has yet restarted after being slated for decommissioning.

March has put Westinghouse front and center in multiple news stories, from its role in Japan’s investment in U.S. nuclear energy to the economic impact that 10 potential AP1000 reactors could bring to the United States.

The Nuclear Regulatory Commission has released its 2025 annual performance assessments of the country’s 95 operating commercial nuclear reactors. And of the 95 reactors, all but five earned the highest marks.

Nuclear power plant assessments can fall under one of five categories: Licensee Response, Regulatory Response, Degraded Cornerstone, Degraded Performance, and Unacceptable Performance. Ninety reactors fell under Licensee Response, the highest performance category in safety and security. Plants that achieve this level of performance are subject to a Reactor Oversight Process (ROP) baseline inspection.

Yasir Arafat, president and chief technology officer of Aalo Atomics, participated in the first day of sessions at the Nuclear Regulatory Commission’s annual Regulatory Information Conference (RIC). There, he recapped some of the company’s recent milestones and revealed new details on what lies ahead for Aalo.

His attendance at the event coincided with a number of announcements in the past two weeks. Those announcements covered new contracts with Global Nuclear Fuel and Baker Hughes, the release of a new strategic roadmap, the completion of fuel enrichment by Urenco USA, and a new approval from the Department of Energy.

Department of Energy Secretary Chris Wright joined U.S. Rep. Mike Lawler (R., N.Y.) at the site of the closed Indian Point nuclear power plant on Friday, March 6, as Lawler called for the reopening of the facility. He emphasized that the shutdown of the plant in 2021 has led to higher electricity costs for the people of New York state and increased strain on the state’s electric grid.
