The Department of Energy’s Office of Nuclear Energy announced December 7 that its new HALEU Consortium is open for membership. And not just from U.S. enrichers, fuel fabricators, and others working in the front-end fuel cycle, but from “any U.S. entity, association, and government organization involved in the nuclear fuel cycle,” and—at the DOE’s discretion—“organizations whose facilities are in ally or partner nations.” The HALEU Consortium will essentially serve as an information clearinghouse to meet DOE-NE’s ongoing needs for firm supply and demand data as it supports the development of a commercial domestic high-assay low-enriched uranium (HALEU) infrastructure to fuel advanced reactors. The consortium is open for business almost one full year after the DOE first requested public input on its structure.

Whether commercial demand for high-assay low-enriched uranium (HALEU) fuel ultimately falls at the high or low end of divergent forecasts, one thing is certain: the United States is not ready to meet demand, because it currently has no domestic HALEU enrichment capacity. But conversations happening now could help build the commercial HALEU enrichment infrastructure needed to support advanced reactor deployments. At the 2022 American Nuclear Society Winter Meeting, representatives from three potential HALEU enrichers, the government, and industry met to discuss their timelines and challenges during “Got Fuel? Progress Toward Establishing a Domestic US HALEU Supply,” a November 15 executive session cosponsored by the Nuclear Nonproliferation Policy Division and the Fuel Cycle and Waste Management Division.

Two reports agree: Diverse advanced reactor fuel cycles can succeed

November 23, 2022, 6:39AMNuclear News

Advanced reactors and small modular reactors with strikingly different coolants and sizes offer an array of different benefits, but when it comes to fuel cycle issues, including spent fuel and waste, they have a lot in common with conventional light water reactors. Two reports released within the last week—a National Academies of Sciences, Engineering, and Medicine (NASEM) consensus committee report two years in the making and a Department of Energy study released by Argonne National Laboratory—address the timely topic of advanced reactor fuel cycle issues. While the NASEM committee ventured to define research and infrastructure needs to support the entire nuclear power fuel cycle, inclusive of new technologies, for decades to come, the DOE report compares the front- and back-end fuel cycle metrics of three reactor designs (from NuScale Power, TerraPower, and X-energy) that have been selected for DOE cost-share–funded demonstrations within this decade. Together, these reports provide assurance that the fuel cycle needs of a fleet of new reactors can be met and point to near-term research and planning needs.

Consolidated Uranium plans to acquire Virginia Energy Resources, which owns Virginia Uranium and the Coles Hill Uranium Project, an undeveloped uranium deposit that sits under about 3,000 acres of land in south central Virginia. The state’s General Assembly has maintained a moratorium on uranium mining since 1982 that was upheld in the courts as recently as 2020, but Consolidated Uranium sees reason for “confidence that the moratorium on developing uranium projects in the state may ultimately be overcome,” and appears content to settle in for a wait.

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.”
