The Department of Energy announced a cost-shared award on November 10 valued at about $150 million for American Centrifuge Operating, a subsidiary of Centrus Energy, to complete the high-assay low-enriched uranium (HALEU) demonstration project it began in 2019. After delays that Centrus attributes in part to the COVID-19 pandemic, the company now has until the end of 2023 to produce the first 20 kilograms of HALEU enriched to 19.75 percent U-235 from the 16-centrifuge cascade it has installed in a DOE-owned Piketon, Ohio, facility—the only U.S. facility currently licensed to produce HALEU.

Another piece of the plan for meeting the urgent need for high-assay low-enriched uranium (HALEU) to fuel advanced reactor deployments fell into place when the Department of Energy held an Industry Day on October 14. Attendees were asked how soon they could deliver 25 metric tons per year of HALEU enriched in the United States from newly mined uranium. Offtake contracts for six or more years of HALEU production at that rate could be used to stock a DOE-owned HALEU bank to “support [HALEU] availability for civilian domestic research, development, demonstration, and commercial use.”

Leaders of X-energy and its TRISO-X subsidiary gathered on October 13 to break ground at the site of what X-energy bills as “North America’s first commercial-scale advanced nuclear fuel facility” in Oak Ridge, Tenn. X-energy expects the TRISO-X Fuel Fabrication Facility (TF3) to create more than 400 jobs and to be commissioned and operational by 2025.

Ultra Safe Nuclear Corporation (USNC) celebrated the opening of its Pilot Fuel Manufacturing (PFM) facility in Oak Ridge, Tenn., on August 18 with a ribbon-cutting ceremony and tour attended by assistant secretary for nuclear energy Kathryn Huff, Tennessee lieutenant governor Randy McNally, U.S. Rep. Chuck Fleischmann (R.), representatives from the offices of Sens. Marsha Blackburn (R.) and Bill Hagerty (R.), and other distinguished guests. The next day, radiological operations began at the privately funded facility, which was designed and built in less than twelve months within an existing industrial building purchased by USNC in 2021.

The Nuclear Regulatory Commission issued its final environmental impact statement (EIS) for the proposed license renewal of Westinghouse Electric’s Columbia Fuel Fabrication Facility (CFFF) in Hopkins, S.C, on July 29, recommending renewal for a 40-year term.

Global Laser Enrichment (GLE) signed separate, nonbinding letters of intent in June with the two largest nuclear power operators in the United States—Constellation and Duke Energy—to assess potential nuclear fuel supply chain cooperation, including support for GLE’s deployment of laser enrichment technology in the United States. According to GLE president and chief commercial officer James Dobchuk, who delivered a presentation on June 7 at the World Nuclear Fuel Market Annual Meeting, the company’s baseline deployment schedule could be accelerated by about three years (under favorable market conditions) to supply the nuclear fuel market with uranium in a range of enrichment levels in 2027.

TRISO-X submitted a license application for a high-assay low-enriched uranium (HALEU) fuel fabrication facility to the Nuclear Regulatory Commission on April 6, the day after parent company X-energy announced that TRISO-X had secured a 110-acre site in Oak Ridge, Tenn., for the construction of the facility, which it is aiming to have operating in 2025.

On April 7, U.S. Sen. John Barrasso (R., Wyo.), ranking member of the Senate Committee on Energy and Natural Resources, introduced the Fueling Our Nuclear Future Act of 2022. The bill would ensure a domestic supply of high-assay low-enriched uranium (HALEU) for advanced nuclear reactors by directing the Department of Energy to prioritize establishing a domestic HALEU enrichment capability and to use enriched uranium held by the DOE and the National Nuclear Security Administration to fuel advanced reactor demonstrations until U.S. commercial enrichment is available. The bill explicitly excludes uranium sourced or processed by any entity owned or controlled by the governments of Russia and China.

X-energy has announced that its wholly owned subsidiary, TRISO-X, plans to build the TRISO-X Fuel Fabrication Facility, dubbed TF3, at the Horizon Center Industrial Park in Oak Ridge, Tenn. X-energy has produced kilogram quantities of fuel at its pilot plant at Oak Ridge National Laboratory through a public-private partnership.

The commercial plant will use high-assay low-enriched uranium (HALEU) to produce TRISO particles, which are fabricated into fuel forms, including the spherical graphite “pebbles” needed to fuel the company’s Xe-100 high-temperature gas reactor. Site preparation and construction are expected to get underway in 2022, and commissioning and start-up are scheduled for as early as 2025, according to X-energy.

The United States must ramp up the domestic production of high-assay low-enriched uranium (HALEU), the panelists agreed during a March 11 members-only webinar held amid heightened concerns about energy security following Russia’s invasion of Ukraine, and the day after Congress approved $45 million for the HALEU Availability Program for fiscal year 2022.

John Starkey, ANS director of public policy, moderated the webinar, which featured panelists Scott Kopple, senior director of government relations at BWX Technologies; Everett Redmond, senior technical advisor at the Nuclear Energy Institute; Benjamin Reinke, senior director of corporate strategy and advisor to the CEO at X-energy; Patrick White, project manager at the Nuclear Innovation Alliance (NIA); and Brad Williams, a member of the Senate Energy and Natural Resources Committee staff.

A recording of the webinar is available to ANS members.

Citing “improving market sentiment,” Tim Gitzel, president and chief executive officer of the Canadian uranium mining company Cameco, announced on February 9 the planned restart of operations at the McArthur River mine in Saskatchewan.

Westinghouse Electric Company and Southern Nuclear have agreed to a plan to install four Westinghouse lead test assemblies in Vogtle-2, a 1,169-MWe pressurized water reactor located in Waynesboro, Ga. Four lead test assemblies containing uranium enriched up to 6 percent U-235 will be loaded in Vogtle-2 in 2023, marking the first time that fuel rods with uranium enriched above 5 percent U-235 are put in use in a U.S. commercial power reactor.

BWX Technologies announced on January 24 that it has been awarded a $4.9 million contract amendment to produce TRISO fuel particles using natural uranium and to demonstrate performance under a defined production schedule. BWXT’s Nuclear Operations Group will perform the work at BWXT’s Lynchburg, Va., facility, where TRISO production was restarted in November 2020. The contract amendment was awarded by Battelle Energy Alliance, which manages Idaho National Laboratory on behalf of the Department of Energy.

A longstanding issue in boiling water reactors—shadow corrosion on zirconium alloy fuel rods and fuel channels—has been reproduced in the Michigan Ion Beam Laboratory as part of an effort to understand and prevent the phenomenon. Research led by Peng Wang, a University of Michigan assistant research scientist in nuclear engineering and radiological sciences, was published in the January 2022 issue of the Journal of Nuclear Materials and described in a recent university news article.

The Department of Energy asks no fewer than 21 multipart questions in its request for information on plans to set up a new program to ensure the availability of high-assay, low-enriched uranium (HALEU) in the United States, encompassing the who, what, when, where, and how of HALEU enrichment, deconversion, fabrication, and transportation. Interested parties were given just 30 days from the December 14 announcement to send their input to the DOE; the deadline is January 13.

Details: Written comments and information are requested on or before January 13. They can be submitted online at regulations.gov or by email to rfi-haleu@hq.doe.gov in a Microsoft Word or a PDF file. See the full request for information published in the Federal Register for additional information.

Oklo plans to fuel its demonstration microreactor with high-assay low-enriched uranium (HALEU). To secure a source of HALEU for its nth-of-a-kind microreactor, Oklo has signed a nonbinding letter of intent with Centrus Energy to cooperate on the deployment of a HALEU production facility.

X-energy and Centrus Energy announced last week that they have completed the preliminary design of the TRISO-X fuel fabrication facility and have signed a contract for the next phase of work. The planned facility would produce TRISO fuel particles and pack those particles into fuel forms, including the spherical graphite “pebbles” needed to fuel X-energy’s Xe-100 high-temperature gas reactor.

Idaho National Laboratory recently released footage of a new experiment at its Transient Reactor Test Facility (TREAT) that simulates what happens to a nuclear fuel pin when it starts to overheat. Go to Twitter for the original post, or cut to the chase and watch a 14-second clip on YouTube.

For years, pressure has been building for a commercial path to a stable supply of high-assay low-enriched uranium (HALEU)—deemed essential for the deployment of advanced power reactors—but advanced reactor developers and enrichment companies are still watching and waiting. In contrast, the uranium spot price soared after Sprott Physical Uranium Trust, a Canadian investment fund formed in July, began buying up U3O8 supplies, causing the price to increase over 60 percent, topping $50 per pound for the first time since 2012. Fueled by growing acknowledgment that nuclear power is a necessary part of a clean energy future, uranium is the focus of attention from Wall Street to Capitol Hill.

The United States Congress needs to take swift action to build a domestic supply of fuel for advanced reactors and to avoid future dependence on Russia for advanced nuclear fuel, the American Nuclear Society wrote in a Sept. 14 letter to the U.S. Senate Energy and Natural Resources Committee.
