US firm tests powerful nuclear laser to advance uranium enrichment

Global Laser Enrichment (GLE), a U.S.-based company, has completed a large-scale demonstration testing campaign of its SILEX laser uranium enrichment process at its Test Loop facility in Wilmington, North Carolina. The campaign, which began in May 2024 and will continue through 2025, aims to produce hundreds of pounds of low-enriched uranium (LEU) for nuclear fuel. GLE’s facility is notable as the world’s only uranium enrichment site that is not government-owned or heavily government-funded. The company, jointly owned by Australia’s Silex Systems and Canada’s Cameco Corporation, is working to commercialize this third-generation laser enrichment technology, which is considered more efficient than traditional methods like gaseous diffusion and gas centrifuge. The SILEX process uses highly selective laser excitation to separate the fissile uranium-235 isotope from uranium-238, increasing the concentration of U-235 needed for nuclear reactors. This technology is seen as pivotal for advancing domestic uranium enrichment capabilities in
