Jeremy Bowen will head the newly created Office of Advanced Reactors when it launches in September, the Nuclear Regulatory Commission announced Monday.

This new office will license and oversee new and advanced reactors. In his role, Bowen will be responsible for the review of advanced reactor applications—reviews that the NRC said will be “expeditious.”

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.

Texas A&M University’s Engineering Experimental Station (TEES) is collaborating with Houston-based start-up ZettaJoule to explore the potential construction of a nonpower research reactor at the university’s College Station campus.

The university believes that hosting ZettaJoule’s ZJ high-temperature, gas-cooled reactor might lead to as much as $1 billion worth of research collaborations, industrial partnerships, and federal funding for its College of Engineering.

Proxima Fusion has signed a memorandum of understanding with the Free State of Bavaria, German electric company RWE, and Max Planck Institute for Plasma Physics (IPP) to build a commercial stellarator fusion power plant in Europe. Based in Munich, Proxima was spun out of IPP in 2023.

A memorandum of understanding has been signed by Oak Ridge National Laboratory and General Atomics Electromagnetic Systems (GA-EMS) with the objective of working together on advanced ceramic matrix composite materials for applications in extreme environments. Materials that can withstand extreme temperatures, radiation, corrosion, and mechanical stress are required in aerospace, defense, energy, and other sectors.

According to the agreement, the San Diego–based GA-EMS will use resources from ORNL’s Manufacturing Demonstration Facility to develop “scalable, efficient manufacturing techniques for extreme environment materials including precursors, fibers, composites, and coatings utilized in carbon/carbon (C/C), carbon/silicon carbide (C/SiC), and SiC/SiC composite systems.”

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.

Last year was marked by a general air of excitement across the nuclear sector. From conference halls to board rooms, momentum manifested in numerous new project announcements, robust federal support, and high-aiming ambitions.

This mood was captured by the 2025 ANS State of the Nuclear Workforce survey, which was conducted from October 1–14. In isolation, the results of this year’s survey are promising; but when compared with the 2024 survey, the story is even clearer, with optimism up almost across the board and renewed attention in the industry’s most critical sectors.

The Department of Energy’s Office of Environmental Management announced that Oak Ridge Office of Environmental Management contractor United Cleanup Oak Ridge recently expanded its partnership with the University of Tennessee to provide learning opportunities for nuclear safety specialists supporting DOE-EM’s cleanup mission.

Commonwealth Fusion Systems makes no small plans. The company wants to build a 400-MWe magnetic confinement fusion power plant called ARC near Richmond, Va., and begin operating it in the early 2030s. And the plans don’t end there. CFS wants to deploy “thousands” of fusion power plants capable of accelerating a global energy transition.

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).

Kairos Power has completed shielded radiation performance testing on a full-scale precast concrete structure at the company’s Reactor Demonstration Campus in Oak Ridge, Tenn., involving the use of an iridium-192 source to measure the movement of radiation through the concrete’s walls, joints, and seams. Kairos expects the results to contribute to schedule and cost estimates for its planned commercial power plants.

Last year, the state of Texas, in partnership with several arms of the federal government, mounted a major response to the New World screwworm (NWS)—a parasitic fly spreading through Mexico.

This year, as the NWS has continued its northward advance toward the U.S. border, efforts to ramp up eradication efforts have continued and intensified on multiple fronts.

A study published in Nature Communications found a correlation between proximity to nuclear power plants and rates of cancer mortality.

The paper, “National Analysis of Cancer Mortality and Proximity to Nuclear Power Plants in the United States,” said that the study could not establish causation but also said that the researchers’ calculations support evidence of 115,586 “cancer deaths attributable to nuclear power plants proximity.”

Amir Bahadori, nuclear engineering program director at Kansas State University, cautioned that this study should not be read as proof that nuclear power plants cause cancer deaths.

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.”

It has been an unusually busy week in the world of West Coast nuclear legislative momentum. In California, a bill is aiming to effectively repeal the state’s nuclear moratorium, while in Oregon, new legislation would have the state create a nuclear feasibility study.

Now, in Washington state, legislators are introducing various measures to move new nuclear prospects forward. One motion requests that Gov. Bob Ferguson respond to the Department of Energy’s request for information regarding states hosting Nuclear Lifecycle Innovation Campuses.

The Thomas Jefferson National Accelerator Facility is leading research supported by two Department of Energy Advanced Research Projects Agency–Energy (ARPA-E) grants aimed at developing accelerator technology to enable nuclear waste recycling, decreasing the half-life of spent nuclear fuel.

Both grants, totaling $8.17 million in combined funding, were awarded through the Nuclear Energy Waste Transmutation Optimized Now (NEWTON) program, which aims to enable the transmutation of nuclear fuels by funding novel technologies for improving the performance of particle generation systems.

As concerns over growing energy needs persist, yet another state is reconsidering nuclear power. A piece of legislation is currently progressing through Oregon’s legislature that would direct the Oregon Department of Energy (ODOE) to conduct a study to assess the feasibility of deploying new power reactors in the state.

Idaho National Laboratory has announced that the National Reactor Innovation Center’s Molten Salt Thermophysical Examination Capability (MSTEC) facility will begin operations in March 2026.

Providing testing capabilities for molten salts, including fuel salts, MSTEC extends INL’s abilities to advance molten salt reactor technology and provide data needed for safe reactor deployment.
