General Matter Advances Paducah Enrichment Plant with NRC License Application
General Matter, a nuclear startup backed by billionaire Peter Thiel, is making significant strides in establishing new domestic uranium enrichment capacity. The company has officially submitted a license application to the U.S. Nuclear Regulatory Commission (NRC) for a commercial uranium enrichment facility located in Paducah, Kentucky.
Phased Licensing and Production Goals
The initial license application is for Low-Enriched Uranium (LEU) under 10 CFR Part 70. However, General Matter has outlined plans to submit an amendment next year to include the production of High-Assay Low-Enriched Uranium (HALEU). The company's ambitious roadmap aims to produce LEU, LEU+, and HALEU at a commercial scale by 2030.
This regulatory milestone follows a series of strategic victories for the startup. In October 2024, General Matter was one of four companies selected by the U.S. DOE to provide enrichment services aimed at establishing a domestic HALEU supply. Subsequently, in August 2025, the company secured a lease with the DOE for 100 acres at the former Paducah Gaseous Diffusion Plant. This lease includes access to a minimum of 7,600 cylinders of existing uranium hexafluoride, which will be utilized for future re-enrichment operations.
General Matter has proposed to deliver 355 metric tons of HALEU under the DOE's $900 million funding program, with production expected to start in 2029.
Furthermore, the startup is not just focusing on supply; it is also securing demand. General Matter has reportedly signed supply contracts with advanced reactor developers, including X-energy and Antares. By leveraging existing infrastructure and securing vital government backing, General Matter is emerging as a key player in revitalizing the U.S. enrichment industry.
