The Nuclear Regulatory Commission has authorized Urenco USA to enrich uranium up to 10 percent U-235 following changes to plant systems and procedures and an operational readiness review. The company announced the news today, two days after the NRC issued its authorization on September 30 and said that all existing and future cascades at its Eunice, N.M., enrichment facility will be licensed to produce both low-enriched uranium, typically enriched to 5 percent fissile U-235, and LEU+, between 5 and 10 percent U-235.

DOE-NE’s newest fuel consortium includes defense from antitrust laws

August 26, 2025, 3:23PMNuclear News

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.

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).

The value of recycled U and Pu brings Standard Nuclear and Shine together

July 9, 2025, 3:00PMNuclear News

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.”

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.
