A North Carolina-based company may have given America a big push toward energy independence and a cleaner future. Interesting Engineering reports that Global Laser Enrichment (GLE) has completed a full-scale test of its innovative SILEX laser uranium enrichment process, marking what could be a new era for domestic nuclear fuel production.
The demonstration, held at GLE’s Test Loop facility in Wilmington, produced hundreds of pounds of low-enriched uranium (LEU) and confirmed the technology’s ability to operate on a commercial scale. The company plans to continue testing through 2025 while expanding its manufacturing base to support large-scale operations.
Developed in partnership with Australia’s Silex Systems, the SILEX process (short for Isotope Separation by Laser Excitation) uses precisely tuned lasers to selectively separate uranium isotopes. The technology is designed to be much more efficient than existing gas centrifugal systems, which have dominated enrichment since the 20th century.
The success of GLE is an important step toward restoring American control over its nuclear fuel supply, which has long depended on imports. The company’s next goal is to open the Paducah laser enrichment facility in Kentucky, the first new enrichment site under review by the Nuclear Regulatory Commission in decades. Once authorized, it could re-enrich more than 200,000 metric tons of uranium tailings and generate up to 6 million LEU separative work units per year.
Nuclear energy remains one of the most debated tools in the clean energy transition. While critics point to radioactive waste and safety concerns, advocates highlight its low-carbon power and its potential to complement renewables like solar and wind.
The transition to clean energy can help curb planet-warming pollution that not only harms public health but also contributes to rising temperatures and more extreme weather events. And by strengthening domestic production, GLE could make nuclear energy safer, cleaner and more sustainable, not just for the United States, but for the world.
“We believe the enrichment activities conducted over the past five months position GLE as America’s next uranium enrichment solution,” said Stephen Long, the company’s chief executive. “Twenty percent of the United States’ electricity supply comes from nuclear power, and GLE is expected to allow the United States to end its dangerous dependence on a fragile uranium fuel supply chain owned by foreign governments.”
