Paducah is positioning itself as an epicenter for nuclear energy as two companies pursuing uranium enrichment in the western Kentucky city have reached significant federal regulatory milestones.
Global Laser Enrichment and General Matter are seeking approval from the U.S. Nuclear Regulatory Commission to develop uranium enrichment facilities in Paducah.
Although the companies are pursuing similar goals, their proposed facilities differ in scope, technology and regulatory progress.
On Oct. 23, the U.S. Nuclear Regulatory Commission announced the completion of its environmental review of Global Laser Enrichment’s proposed Paducah Laser Enrichment Facility, recommending that the agency issue a license authorizing the facility’s construction and operation.
"The NRC's issuance of the Final Environmental Impact Statement represents a significant regulatory milestone for the PLEF and reflects the NRC staff's comprehensive and efficient review of our application,” Global Laser Enrichment Vice President of Safety, Security and Compliance Tim Knowles said in a news release. “We appreciate the agency's commitment to a rigorous, timely, and transparent licensing process.”
With the environmental review complete, the company’s next regulatory hurdle is the agency’s Safety Evaluation Report, which assesses whether the facility meets federal nuclear safety and security requirements. The agency expects to issue the report by January 2027.
Global Laser Enrichment is an American nuclear technology company developing laser-based uranium enrichment technology for use in nuclear fuel production. Founded in 2007, the company is jointly owned by Australian technology firm Silex Systems and Canadian uranium supplier Cameco Corporation. The name SILEX is an acronym for “Separation of Isotopes by Laser Excitation.”
In March, Kentucky Gov. Andy Beshear announced that Global Laser Enrichment would invest $1.76 billion in its proposed Paducah Laser Enrichment Facility. The facility would occupy a 322-acre site five miles west of Paducah, part of a larger 665-acre property adjacent to the U.S. Department of Energy’s former Paducah Gaseous Diffusion Plant, which operated from 1953 until 2013.
With plans to begin operations in 2030, pending approval, Global Laser Enrichment would use specialized lasers to recover usable uranium from depleted uranium left over from previous enrichment operations at the former Paducah Gaseous Diffusion Plant.
The process involves converting depleted uranium into a gaseous form, then using finely tuned lasers to separate uranium isotopes, increasing the concentration of uranium-235, a naturally occurring isotope needed to sustain the nuclear reactions that generate electricity. The facility would not generate electricity. Instead, the process could recover uranium from previous enrichment operations, turning existing stockpiles into a new source of nuclear fuel.
On Oct. 29, the U.S. Nuclear Regulatory Commission accepted General Matter’s initial license application for review, initiating its federal safety and environmental review process.
General Matter is a California-based nuclear fuel startup planning to develop a $1.5 billion uranium enrichment facility in Paducah. Unlike Global Laser Enrichment’s plan for an adjacent facility, General Matter seeks to build its facility on the former Paducah Gaseous Diffusion Plant site.
The agency’s decision does not authorize construction or operation of the enrichment facility. Instead, it allows the evaluation process to begin.
The facility would produce low-enriched uranium for conventional nuclear reactors, with plans to expand into the production of high-assay low-enriched uranium, a specialized fuel for advanced nuclear reactors.
According to a notification letter from the U.S. Nuclear Regulatory Commission, the agency typically takes 18 months to complete a review of this scope, putting the expected completion date in April 2028. However, the letter notes that portions of the review could be expedited depending on General Matter’s continued engagement with the agency and the availability of NRC resources.
