One Document Left in a Multi-Year Licensing Campaign

The U.S. Nuclear Regulatory Commission has released its final environmental impact statement (EIS) for Global Laser Enrichment's proposed Paducah Laser Enrichment Facility (PLEF) near Paducah, Kentucky. GLE and its technology partner Silex Systems said the final EIS supports issuance of a license to begin construction. The only remaining step before the NRC issues a combined construction and operating license is the safety evaluation report (SER).

GLE completed its license application in July 2025. Silex said it expects the NRC to publish the SER before the end of contract year 2026, with license approval following in 2027. GLE is targeting the start of operations at PLEF in 2030. The NRC began preliminary EIS work in September 2025 and issued a draft for public comment on March 27, 2026.

Environmental Findings: Small to Medium in Four Areas

The final EIS rated effects as small to medium in four resource areas — surface water, ecology, transportation and socioeconomics — with the socioeconomic effects described as mostly positive. All other resource categories were assessed as small.

What the License Would Authorize

GLE is seeking authority to re-enrich depleted uranium hexafluoride (DUF6) tails back to natural levels and to enrich natural-grade UF6 to a maximum of 8 percent uranium-235 by weight — inside the 5 to 20 percent band that defines high-assay low-enriched uranium. The application covers up to 2,000 metric tons of uranium per year of equivalent natural UF6 and 6 million separative work units (SWU) per year of low-enriched uranium output, using Silex's proprietary laser enrichment technology.

Silex Systems, an Australian company, holds 51 percent of GLE and developed the laser technology that would underpin the plant. Gas centrifuge enrichment remains the dominant global technology, but laser enrichment is forecast to record the highest growth rate, supported by U.S. government funding directed at GLE and Laser Isotope Separation Technologies.

Site Advantage and Public Support

GLE acquired the 665-acre PLEF site in November 2024 and submitted its environmental report to the NRC a month later. The land is adjacent to the former Paducah Gaseous Diffusion Plant, which ceased enrichment operations in 2013. Depleted UF6 tails left over from that plant are stored on site and would be re-enriched at PLEF — a feedstock advantage no greenfield project in the United States currently enjoys.

Financial backing has followed the licensing progress. In January 2026 the Department of Energy awarded GLE $28.5 million, and in March 2026 the Commonwealth of Kentucky and McCracken County government gave preliminary approval to a performance-based incentive package worth approximately $98.9 million.
