General Matter Submits NRC License for Paducah Enrichment Plant with HALEU Plans
General Matter has officially submitted its first license application to the US Nuclear Regulatory Commission (NRC) to construct a commercial uranium enrichment plant in Paducah, Kentucky. The ambitious $1.5 billion facility represents a significant step toward bolstering domestic uranium processing capabilities, with a strategic roadmap that includes high-assay low-enriched uranium (HALEU) production.
Initially, the Paducah facility will focus on producing low-enriched uranium (LEU) for conventional nuclear reactors. However, the company has outlined a clear two-part licensing strategy. By securing the initial LEU license first, General Matter aims to streamline the regulatory process and accelerate the construction timeline. The company plans to submit a license amendment next year to officially add HALEU production capabilities, which are absolutely critical for the deployment of advanced nuclear reactors.
Strategic Site Lease and Feedstock Advantages
The foundation for this massive project was laid in August 2025 when General Matter leased a 100-acre site at the former Paducah Gaseous Diffusion Plant. This location offers immense logistical and financial advantages for the new commercial enrichment facility. Crucially, the lease agreement includes access to a minimum of 7,600 cylinders of existing uranium hexafluoride feedstock.
This existing feedstock will be utilized for re-enrichment operations, saving approximately $800 million in avoided disposal costs while providing a consistent, US-origin supply of feed for future LEU and HALEU production.
By leveraging this existing inventory, General Matter significantly reduces its initial capital expenditure requirements and mitigates supply chain risks associated with sourcing fresh feedstock. The integration of HALEU production into the Paducah site underscores the growing recognition of advanced nuclear fuels as a cornerstone of future energy security. As the NRC reviews the application, the nuclear industry will be closely watching how this two-part strategy influences future enrichment licensing frameworks in the United States.
