Most advanced reactor designers plan to use high-assay low-enriched uranium (HALEU) fuel, including the two reactors selected by DOE’s Advanced Reactor Demonstration Program. Moreover, some utilities seek to use slightly higher enrichments in existing light-water reactors. However, there is an insufficient supply of HALEU to supply demonstration reactor needs, no domestic HALEU enrichment capability, and significant uncertainty surrounding long-term HALEU demands. To address these challenges, DOE has been down blending high-enriched uranium and has solicited input on a HALEU Availability Program. In addition, several enrichment companies have established HALEU programs. At this panel, panelists from the enrichment industry and government discuss the status and next steps for establishing a domestic HALEU fuel supply chain. Establishing domestic HALEU production capability will enable the US to expand its position in the global nuclear energy market while promoting its own nonproliferation agenda.
