What LIGHTBRIDGE Corp does
In the company’s own words
Lightbridge Corporation (Nasdaq: LTBR) develops metallic nuclear fuel for water-cooled reactors, including pressurized-water and boiling-water reactors, heavy-water reactors, and small modular reactors. Its Lightbridge Fuel™ uses uranium-zirconium alloy rods with a proprietary helical geometry and is designed to improve reactor power output, fuel performance, safety, and proliferation resistance. The technology remains in research and development and requires testing, regulatory review, and qualification before commercial use. Potential customers include nuclear utilities and operators of existing and new reactors, as well as reactor and fuel vendors; the company is also pursuing fuel development with Idaho National Laboratory. Its development work includes irradiation testing, fuel-performance modeling, fabrication-process development, and preparation for lead test rods and assemblies in commercial reactors. Lightbridge has one principal business focused on nuclear fuel technology, rather than separately reported operating segments. In November 2025, irradiation testing of its enriched uranium-zirconium fuel-material samples began at the laboratory’s Advanced Test Reactor. The company was founded around development of metallic fuel and has focused on this technology since 2010.
