The U.S. Nuclear Regulatory Commission (NRC) has accepted General Matter's license application for a planned $1.5 billion uranium enrichment facility in McCracken County, Kentucky, moving the project into formal licensing review. The site is a parcel at the U.S. Department of Energy site that once housed the former Paducah Gaseous Diffusion Plant.

LEU first, HALEU later

General Matter initially aims to produce low-enriched uranium (LEU), with the company later intending to seek authorization to produce high-assay low-enriched uranium (HALEU) to supply advanced reactor customers. The sequencing is deliberate: LEU is a conventional product with an existing market and regulatory precedent, while HALEU — enriched to between 5% and 20% uranium-235 — requires additional safety and safeguards scrutiny before any authorization can be granted.

2029 target for full operations

General Matter targets full operations by 2029. The NRC's acceptance of the application is a procedural milestone rather than an approval, but it is a necessary one: it confirms the agency has deemed the application sufficiently complete to begin the review.

Policy tailwinds on display

The project was highlighted at an event at the DOE site in West Paducah attended by U.S. Department of Energy Assistant Secretary Tim Walsh, and the NRC announced its acceptance of the application on social media on a Thursday. The visibility is consistent with a broader federal push to expand domestic nuclear fuel production capacity after years of dependence on imported enrichment services.

The NRC's acceptance is described as a regulatory step toward expanding domestic nuclear fuel production capacity — not a license grant.

What it means for HALEU supply

If licensed and built, the Paducah-area plant would add a second U.S. commercial enrichment entrant pursuing HALEU alongside Centrus, whose Piketon, Ohio expansion is being funded through DOE task orders. Reusing an existing DOE site with legacy enrichment infrastructure — and a workforce familiar with the technology — could shorten permitting and construction timelines relative to greenfield projects.

The key uncertainty remains timing. A 2029 operations target for LEU leaves HALEU production further out, meaning advanced reactor developers cannot count on this facility for initial cores. For now, the NRC docket is the milestone to watch.
