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).

In the past week, two pieces of nuclear legislation moved forward in two Midwestern states.

In Wisconsin, a bill to create new tax credits for new power plants passed through the state Assembly and went to the Senate, while in Indiana, a bill to simplify the state approval process for new plants passed through the state Senate and went to the House.

BWX Technologies announced on January 26 that it has begun operating its Centrifuge Manufacturing Development Facility in Oak Ridge, Tenn., with the purpose of reestablishing a domestic uranium enrichment capability to meet U.S. national security needs. The facility is part of a program funded by the Department of Energy’s National Nuclear Security Administration to supply enriched uranium for defense needs.

Nuclear Transport Solutions and Westinghouse have signed a strategic agreement to codevelop NTS’s Pegasus—a transport package for high-assay, low-enriched uranium fuel.

The companies signed the agreement at the British Embassy in Washington, D.C., on January 22, taking what Westinghouse called “an important step in making HALEU available to enable advanced nuclear energy in the U.S. and UK.”

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.

A nuclear energy working group convened by the Hawaii State Energy Office (HSEO) and tasked with investigating the feasibility of bringing nuclear to the state recently released a report that concluded that—for now—nuclear is not right for Hawaii.

The bill: The HSEO was ordered to convene a nuclear energy working group by state Senate Concurrent Resolution 136, which was passed during last year’s legislative session. The task force was specifically charged with investigating the feasibility of advanced nuclear power technologies in the state, along with identifying barriers to and risks associated with deploying those technologies. Those benefits and risks were far reaching in scope, including regulatory, statutory, financial, social, and environmental factors.

Centrus Energy Corp. is planning a major expansion of its Oak Ridge, Tenn., Technology and Manufacturing Center. The build-out would allow it to expedite large-scale deployment of centrifuges.

Amir Vexler, Centrus president and CEO, announced the expansion on January 23, along with Tennessee Gov. Bill Lee and Deputy Gov. Stuart McWhorter.

The American Nuclear Society is hosting a new Supplier Showcase webinar, “Digital Tools for Power Uprates: Using DVR and PEPSE to Enhance MUR and Performance Studies,” on January 27 from 2:00 p.m. to 3:00 p.m. (EST).

The webinar is free for all viewers and requires registration.

As executive vice president for industry strategy at the Institute of Nuclear Power Operations, Jeff Place leads INPO’s industry-facing work, engaging directly with chief nuclear officers.

The EDF Group’s Nuclear Operations business, which is the majority owner of the five operating and three decommissioning nuclear power plant sites in the United Kingdom, has released its annual update on the U.K. fleet. UK Nuclear Fleet Stakeholder Update: Powering an Electric Britain includes a positive review of the previous year’s performance and news of a billion-dollar boost in the coming years to maximize output across the fleet.

The Department of Energy’s Office of Environmental Management said it has transferred four robotic demolition machines from the department’s Portsmouth Site in Ohio to Oak Ridge, Tenn., saving the office more than $1.7 million by avoiding the purchase of new equipment.

General Fusion has entered into a definitive business combination agreement with Spring Valley Acquisition Corp. (SVAC) that would make General Fusion the first publicly traded pure-play fusion firm, the company announced on January 22. The business combination is projected to be completed in mid-2026.

Yesterday, Oak Ridge National Laboratory announced that it is in the process of partnering with Type One Energy and the University of Tennessee–Knoxville. That partnership will have one primary goal: to establish a high-heat flux facility (HHF) at the Tennessee Valley Authority’s Bull Run Energy Complex in Clinton, Tenn.

The Department of Energy is considering revisions to its regulations covering worker safety and health to help expedite the development of new nuclear reactors under its Reactor Pilot Program.

According to the DOE, the proposed changes to 10 CFR Part 851, “Worker Safety and Health Program,” have the benefit of “increased flexibility, streamlined processes, cost savings, enhanced agility, and improved worker engagement.”

Igunma

American Nuclear Society member Thompson Odion Igunma is a doctoral candidate in materials science and engineering at the University of Florida (UF) conducting research in collaboration with the Computational Mechanics and Materials Group at Idaho National Laboratory. His work focuses on advanced modeling of the complex interplay between molten salt corrosion, irradiation, and changes in alloy microstructure.

“I see molten salt reactors as a pivotal part of the next generation of nuclear energy,” Igunma said. “Their unique combination of safety, efficiency, and fuel flexibility makes them ideally suited to complement renewables in a low-carbon energy mix.”

Kairos Power has finalized a contract with the Department of Energy to receive high-assay low-enriched uranium (HALEU) from the agency for the company’s Hermes low-power demonstration reactor, currently under construction in Oak Ridge, Tenn.

In partnership with Los Alamos National Laboratory, Kairos intends to use the DOE-provided material to produce HALEU TRISO fuel pebbles for Hermes. The company views the Hermes test reactor and the fuel fabrication program as crucial to the eventual success of its power-producing Hermes 2 demonstration plant, also to be sited in Oak Ridge, and future commercial fluoride salt–cooled high-temperature reactors.

Update: Operation of Unit 6 at Kashiwazaki Kariwa nuclear power plant in Japan’s Niigata Prefecture was suspended Thursday morning after its initial restart on the evening of Wednesday, January 21. According to TEPCO spokesperson Takashi Kobayashi, an alarm sounded “during reactor start-up procedures.” The cause is currently under investigation, but there is no danger inside or outside the plant. Plant chief Takeyuki Inagaki said at a news conference, “The equipment is essential to safe operation, and we will examine it inside-out.”

On January 16, Tenn. Gov. Bill Lee, Deputy Gov. Stuart McWhorter, and officials from Laser Isotope Separation Technologies announced the company’s plans to expand in Oak Ridge, Tenn. That expansion will come with a $1.38 billion investment from LIS Technologies for what the company says will be the first commercial laser uranium enrichment plant in the United States.

London-based professional services organization and maritime classification society Lloyd’s Register has brought together a group of experts from the U.K. nuclear, maritime, insurance, and regulatory sectors with the primary goal of establishing international standards “for safe, secure, and commercially viable nuclear-powered ships.”

This Maritime Nuclear Consortium includes Lloyd’s Register as the group’s lead, safety administrator, and secretariat; Rolls-Royce, specializing in advanced reactor design; Babcock International Group (ship design, construction, and support); Global Nuclear Security Partners (security and safeguards); Stephenson Harwood (legal and regulatory issues); and NorthStandard (insurance).

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.
