General Matter, Inc. is moving on two tracks in Paducah, Kentucky: licensing and construction preparation. In September 2026 the California-based company submitted its first license application to the U.S. Nuclear Regulatory Commission to build and operate a proposed $1.5 billion commercial uranium enrichment facility. The project is part of a federally backed effort to rebuild domestic enrichment capacity.

A HALEU plan arrives in 2027

The initial application is for enrichment, but General Matter plans to submit an amended NRC application in 2027 to produce HALEU. HALEU is uranium enriched to between 5% and 20% uranium-235, compared with 3% to 5% for power-reactor-grade LEU. Most advanced reactor designs need HALEU or higher-assay fuel, which is why DOE selected General Matter for a $900 million HALEU task order in January 2026.

General Matter announced on Sept. 28 that it had begun site preparations for HALEU production despite not yet having obtained authorization.

NRC review is the gate

The NRC accepted General Matter’s application for review only in late October. That procedural step is not a license. The company still needs a safety review and an authorization before it can operate an enrichment plant. Its plan to add HALEU production through an amended application means the final licensing envelope will be defined later, not at the outset.

The sequence is unusual but not surprising. Advanced reactor developers and federal agencies are trying to compress schedules for a fuel that Russia currently supplies essentially all of commercially. DOE’s awards are milestone-based, so federal money arrives as targets are met rather than upfront. For General Matter, site preparation can proceed while licensing does, but production cannot.

What to watch

The key tests are the NRC’s review schedule, the 2027 HALEU amendment, and whether General Matter’s $1.5 billion plant can reach commercial operation in time for reactors that are still in planning and application. The scale of future HALEU demand remains uncertain because many advanced reactors are not yet under construction. General Matter’s early site work is a bet that licensing and demand will converge. The NRC docket will show whether that bet holds.
