The startup of a new cascade of gas centrifuge at Urenco USA’s (UUSA) uranium enrichment facility in Eunice, N.M., came ahead of schedule and on budget, according to the company.

Kairos Power and BWX Technologies announced today that they will work together to “collaboratively explore” optimizing commercial production of TRISO fuel for Kairos’s planned advanced reactor fleet—beginning with the 50-MWe Hermes 2, slated for operation in 2030—and other potential customers. Their collaboration could include jointly developing a TRISO fuel fabrication facility.

Canadian uranium provider Cameco calculated an end-of-August spot price for uranium of $75.13—up from the previous month’s spot price of $71.10. Cameco continues to list a long-term price of $81.00 for August and has set it at $80.00 or $81.00 all year.

The Department of Energy made conditional commitments yesterday to provide high-assay low-enriched uranium to three companies: reactor developer Antares Nuclear; fuel fabricator Standard Nuclear; and Natura Resources, which is backing Abilene Christian University’s development of a small Molten Salt Research Reactor and pursuing a commercial reactor design of its own. Following a contracting process, some of the companies “could receive their HALEU later this year.”

The Department of Energy's Office of Nuclear Energy is setting up a nuclear fuel Defense Production Act Consortium that will seek voluntary agreements with interested companies “to increase fuel availability, provide more access to reliable power, and end America’s reliance on foreign sources of enriched uranium and critical materials needed to power the nation’s nuclear renaissance.” According to an August 22 DOE press release, the plan invokes the Defense Production Act (DPA) to give consortium members “defense from antitrust laws when certain criteria are met” and “allow industry consultation to develop plans of action.” DOE-NE is looking for interested companies to join the consortium ahead of its first meeting, scheduled for October 14.

Eleven high-burnup fuel rods manufactured by Global Nuclear Fuel have been delivered to Pacific Northwest National Laboratory for a battery of destructive tests. PNNL’s evaluation will provide GNF and the Department of Energy with information about the performance of the fuel, which—like other fuels developed through the DOE’s Accident Tolerant Fuel program— was engineered to handle longer operating cycles, improve fuel cycle economics, and support power uprates for existing light water reactors.

A strategic collaboration has been launched by Lightbridge Corporation and Oklo Inc. to explore locating Lightbridge’s fuel fabrication facility within Oklo’s planned advanced fuel manufacturing facility. The collaboration aims to “accelerate the commercialization of advanced nuclear fuels through joint fuel fabrication and research and development, including manufacturing fuel using repurposed plutonium from legacy materials,” according to the companies.

Small modular reactor developer X-energy, together with its fuel-developing subsidiary TRISO-X, has selected Clark Construction Group to finish the building construction phase of its advanced nuclear fuel fabrication facility, known as TX-1, in Oak Ridge, Tenn. It will be the first of two Oak Ridge facilities built to manufacture the company’s TRISO fuel for use in its Xe-100 SMR. The initial deployment of the Xe-100 will be at Dow Chemical Company’s UCC Seadrift Operations manufacturing site on Texas’s Gulf Coast.

Uranium provider Cameco has calculated an end-of-July spot price for uranium of $71.10—a decline from the $78.50 of the previous month. Cameco lists a long-term price of $81.00 for July, which is the same price that was listed in January. From February to June, the long-term price was $80.00.

Uranium futures were about $71.45 per pound on August 4, according to online analysis firm Trading Economics, which noted that continued prices near $71.50 are maintaining the price drop from the seven-month high of $79.00 in mid-June. The relatively low prices are related to a lack of buying from holding funds, which have received lowered bids from utilities. Nevertheless, uranium prices are higher at this point, compared with the $63.70 price in mid-March this year.

The Department of Energy’s Office of Environmental Management announced it has signed a lease with General Matter for the reuse of a 100-acre parcel of federal land at the former Paducah Gaseous Diffusion Plant in Kentucky for a new private-sector domestic uranium enrichment facility.

Lightbridge Corporation has fabricated samples of nuclear fuel materials made of an enriched uranium-zirconium alloy, matching the composition of the alloy that the company intends to use for its future commercial Lightbridge Fuel product. The fuel is designed to improve the performance, safety, and proliferation resistance of nuclear reactors, according to the company. The enriched coupon samples will now be placed into capsules for irradiation testing in Idaho National Laboratory’s Advanced Test Reactor.

From 2003 to 2011, staff at the Department of Energy’s Savannah River Site downblended high-enriched uranium in the site’s H Canyon, producing over 300 metric tons (MT) of low-enriched uranium that was fabricated into fuel. The facility has since been idled, but downblending could soon begin again—this time to high-assay low-enriched uranium (HALEU).

BWX Technologies (BWXT) has achieved a key milestone in its project to additively manufacture advanced forms of TRISO fuel for Generation IV advanced nuclear reactors. The Lynchburg Technology Center of subsidiary company BWXT Advanced Technologies, located in Lynchburg, Va., has successfully installed and tested a chemical vapor infiltration (CVI) furnace that solidifies pre-forms that are then filled with TRISO particles, a fuel consisting of carbon and silicon layers surrounding a uranium kernel.

The Department of Energy has announced a program to accelerate nuclear fuel fabrication for new test reactors. The Fuel Line Pilot Program would see the DOE approve facilities developed by U.S. companies to produce the fuel needed for test reactors the DOE expects to authorize under the Reactor Pilot Program announced in June. Like the reactors they’re meant to fuel, the fabrication facilities would be built on sites outside the DOE’s national laboratories but authorized by the DOE under “a fast-tracked approach to enable future commercial licensing activities for potential applicants.”

An article in the OECD Nuclear Energy Agency’s July news bulletin noted that a first test has been completed for the High Burnup Experiments in Reactivity Initiated Accident (HERA) project. The project aim is to understand the performance of light water reactor fuel at high burnup under reactivity-initiated accidents (RIA).

Shine Technologies has been developing fusion-adjacent technologies in Janesville, Wis., including nuclear fuel recycling, since its founding in 2005. Standard Nuclear of Oak Ridge, Tenn., was formed just last year but holds a TRISO fuel production technology backed by years of research and development since it acquired Ultra Safe Nuclear’s fuel manufacturing assets after that company’s bankruptcy in October 2024. Now, Shine and Standard Nuclear have announced plans to work together on a “strategic partnership to advance nuclear fuel recycling and U.S. fuel security.”

Uranium provider Cameco has calculated an end-of-June spot price of $78.50 for uranium—a substantial jump from $71.55 the previous month. Cameco continues to list a long-term price of $80.00, a price that has remained unchanged since February.

Global Laser Enrichment announced that it has submitted its safety analysis report to the Nuclear Regulatory Commission for the planned Paducah Laser Enrichment Facility (PLEF). This follows GLE’s December 2024 submission of the plant’s environmental report, now completing GLE’s full license application for NRC review.

Centrus Energy has secured a contract extension from the Department of Energy to continue—for one year—its ongoing high-assay low-enriched uranium (HALEU) production at the American Centrifuge Plant in Piketon, Ohio, at an annual rate of 900 kilograms of HALEU UF₆. That's the same amount of HALEU—900 kg—that the company today announced it has delivered to the DOE, completing Phase II of its contract. According to Centrus, the contract extension, which allows the company to begin Phase III, is valued at about $110 million through June 30, 2026.

In the fall of 2023, a small Zeno Power team accomplished a major feat: they demonstrated the first strontium-90 heat source in decades—and the first-ever by a commercial company.

Zeno Power worked with Pacific Northwest National Laboratory to fabricate and validate this Z1 heat source design at the lab’s Radiochemical Processing Laboratory. The Z1 demonstration heralded renewed interest in developing radioisotope power system (RPS) technology. In early 2025, the heat source was disassembled, and the Sr-90 was returned to the U.S. Department of Energy for continued use.
