The University of Illinois at Urbana-Champaign Nuclear Plasma and Radiation Engineering (NPRE) Department announced yesterday that the Nuclear Regulatory Commission has approved a fuel qualification methodology topical report for the high-temperature gas-cooled reactor the university wants to construct. The topical report was prepared by Ultra Safe Nuclear and submitted by UIUC to the NRC in March 2024. It describes the fuel that would be used in the microreactor that UIUC plans to host—initially containing uranium enriched to 9.9 percent U-235—and how it would be tested. The NRC issued its approval and a final safety evaluation on April 1.

Framatome announced that it has inaugurated a new workshop dedicated to the fabrication of fuel for research reactors and targets for medical isotopes at the company’s Romans-sur-Isère site in France. The workshops are part of Framatome’s CERCA division, which manufactures fuel and irradiation targets for research reactors.

BWX Technologies Inc. has purchased about 97 acres of land in an Oak Ridge, Tenn., industrial park where the company expects to build a uranium enrichment facility using a technology called DUECE, or, Domestic Uranium Enrichment Centrifuge Experiment. DUECE was developed at Oak Ridge National Laboratory to provide enriched uranium for the Department of Energy’s National Nuclear Security Administration, and BWXT is several months into a yearlong engineering study to evaluate options for deploying a centrifuge pilot plant using DUECE.

Scientists at Argonne National Laboratory are investigating a used nuclear fuel recycling technology that could lead to a scaled-down and more efficient approach to metal recovery, according to a recent news article from the lab. The research, led by Argonne radiochemist Anna Servis with funding from the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), could have an impact beyond the nuclear fuel cycle and improve other high-value metal processing, such as rare earth recovery, according to Argonne.

The research: Servis’s work is being carried out under ARPA-E’s CURIE (Converting UNF Radioisotopes Into Energy) program. The specific project—Radioisotope Capture Intensification Using Rotating Packed Bed Contactors—started in 2023 and is scheduled to end in January 2026.

U.S. uranium production increased throughout 2024, with more growth planned in 2025. The producers who can make that happen, however, were burned before by a “renaissance” that didn’t take off. Now they are watching and waiting for signals from Washington, D.C., including the impacts of tariffs, shifting relationships with global uranium producers, and funding for the enrichment task orders designed to boost demand for U.S. uranium.

Idaho National Laboratory recently conducted a safety test on high-burnup fast reactor fuel from historic irradiation testing at the lab’s Experimental Breeder Reactor-II (EBR-II). According to the Department of Energy, which announced the work March 12, it’s the first such safety test to be performed in over 20 years.

General Atomics Electromagnetic Systems (GA-EMS) has announced that it has subjected nuclear thermal propulsion (NTP) fuel samples to several “high-impact” tests at NASA’s Marshall Space Flight Center (MSFC) in Huntsville, Ala. That news comes as NASA, the Department of Defense, the Department of Energy, and multiple nuclear and space technology companies continue to build on recent progress in nuclear thermal rocket design and demonstration.

The Department of Energy has offered up to $80 million of Inflation Reduction Act funding to back potential advancements in high-assay low-enriched uranium production. The new funding opportunity, announced in December, will prioritize technological advancement developing innovative technologies and approaches to strengthen the front-end of the HALEU supply chain. Applications are due by 5:00 p.m. (EST) on February 26, 2025.

Just one day after Urenco USA (UUSA) was picked by the Department of Energy as one of six contractors eligible to compete for future low-enriched uranium task orders, the Nuclear Regulatory Commission on December 11 formally approved the company’s license amendment request to boost uranium enrichment levels at its Eunice, N.M., enrichment facility to 10 percent fissile uranium-235—up from its current limit of 5.5 percent.

General Atomics Electromagnetic Systems (GA-EMS) announced last week that unfueled test rods featuring the company’s SiGA fuel cladding—made of a silicon carbide composite material—successfully survived 120 days of irradiation in the Advanced Test Reactor (ATR) at Idaho National Laboratory.

Los Alamos National Laboratory researchers have performed a critical experiment using high-assay low-enriched uranium (HALEU) TRISO fuel. It is the nation’s first criticality safety experiment using HALEU fuel in more than 20 years. On November 21, LANL announced the work of its Deimos team, which earlier this year carried out an experiment at the National Criticality Experiments Research Center (NCERC), operated by LANL at the Nevada National Security Site.

The Department of Energy announced November 19 that up to $16 million is available through a new High-Assay Low-Enrichment Transportation Package funding opportunity to research, develop, and acquire Nuclear Regulatory Commission licensing for transportation of HALEU—using new or modified packages.

Clean Core Thorium Energy (Clean Core) announced November 12 that test rodlets of its patented thorium-uranium fuel design known as ANEEL (advanced nuclear energy for enriched life) have reached a burnup milestone in the Advanced Test Reactor (ATR) at Idaho National Laboratory.

TerraPower announced today that it has signed a term sheet with ASP Isotopes Inc. as the first step of a planned investment in the construction of a high-assay low-enriched uranium (HALEU) enrichment facility and the eventual purchase of HALEU produced at the facility to fuel its Natrium fast reactors.

If we needed more proof that this is a “nuclear week”—in the words of Energy Secretary Jennifer Granholm on Wednesday, as she announced small modular reactor funding while celebrating tech company investments in advanced reactors—the Department of Energy came through late yesterday when, just nine days after announcing six contracts for high-assay low-enriched uranium (HALEU) deconversion, it announced four contracts for HALEU enrichment services worth up to $2.7 billion. Those contracts are going to Centrus Energy’s American Centrifuge Operating subsidiary, General Matter, Orano Federal Services, and Urenco USA’s Louisiana Energy Services.

Oklo Inc. announced yesterday that a safety design report for the Aurora fuel fabrication facility the company plans to build at Idaho National Laboratory has the approval of the Department of Energy. At the facility, Oklo plans to use high-assay low-enriched uranium (HALEU) that has been recovered from used Experimental Breeder Reactor-II fuel to produce fuel for its first planned microreactor—dubbed Aurora—which is also set for deployment at INL.

On October 8, the Department of Energy’s Idaho Operations Office released the draft environmental assessment (EA) Demonstration of Microreactor Experiment (DOME) Test Bed Operations. The draft EA assesses the potential environmental impacts of plans to use the containment dome of the former Experimental Breeder Reactor-II at Idaho National Laboratory’s Materials and Fuels Complex (MFC) to test multiple TRISO-fueled advanced reactor designs on a micro scale.

The American Nuclear Society recently issued an open letter in support of a science-based approach to the regulation of high-assay low-enriched uranium (HALEU) fuels for commercial nuclear energy, voicing member concerns about hyperbole in a recent article published in Science, which advocated for restrictions on the use of HALEU despite decades of effective safeguards and security. This is not the first time ANS has stepped in to present the measured opinion of its membership on the value and appropriate regulation of HALEU.

The Department of Energy awarded $17 million on August 30 for 16 experiment and analysis projects expected to yield criticality data that will assist the Nuclear Regulatory Commission in licensing and regulating high-assay low-enriched uranium and the fuel infrastructure—including packaging and transportation containers—required to demonstrate and deploy HALEU-fueled advanced nuclear reactors. Project teams include six national laboratories taking lead roles in partnership with other labs, universities, and multiple industry partners.
