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.

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.

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).

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.

Ensuring energy resilience for our nation is on the minds of leaders and citizens alike. Advances in nuclear power technologies are increasing needs within the nuclear industry supply chain. Savannah River National Laboratory’s decades of experience in nuclear materials processing makes the lab uniquely qualified to meet the current and future challenges of the nuclear fuel cycle.

He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.
