The U.S. Nuclear Regulatory Commission has accepted General Matter's license application for a planned $1.5 billion commercial uranium enrichment facility on DOE-owned land at the former Paducah Gaseous Diffusion Plant site in McCracken County, Kentucky. Acceptance begins the formal regulatory review process for the project.

LEU First, HALEU Later

General Matter aims to produce low-enriched uranium at the McCracken County plant and later seek authorization for high-assay low-enriched uranium to supply commercial reactors and reduce reliance on foreign imports. That sequencing is significant: HALEU — uranium enriched to between 10% and 20% U-235 — requires a dedicated facility and separate authorization from the NRC for production.

By licensing for LEU first, General Matter can begin generating revenue and demonstrating operational competence while the HALEU authorization proceeds on its own track. The company targets full operations by 2029.

A Site With History

The choice of the former Paducah gaseous diffusion site places new centrifuge technology on ground that once hosted one of the largest enrichment operations in the United States. DOE ownership of the land simplifies siting, and the project is positioned as a step toward expanding domestic nuclear fuel production capacity.

NRC acceptance of an application is a procedural milestone, not an approval — but it starts a review clock that determines whether a new U.S. enrichment plant can enter service this decade.

The Foreign-Reliance Problem

Russia and China maintain the first commercial-scale infrastructure to produce HALEU globally, even as Western nations have applied import bans or trade restrictions on Russian nuclear materials. Centrus Energy is deploying fuel centrifuges under DOE contracts as a domestic commercial supplier, and General Matter would add a second U.S. pathway if licensed.

The HALEU attributes that drive demand are well established: smaller reactor core sizes, higher power density, longer operating cycles between refueling, higher fuel use and reduced nuclear waste volume. Those characteristics are what make HALEU central to advanced reactor designs — and what make a licensing decision in McCracken County consequential well beyond Kentucky.
