Profile
Develops Lightbridge Fuel, a metallic uranium-zirconium design for water-cooled reactors. The business is pre-commercial and built around testing, qualification, licensing, and future royalties, with execution tied to INL work, HALEU supply, regulatory approvals, and utility adoption.
Develops Lightbridge Fuel, a proprietary metallic uranium-zirconium fuel for water-cooled reactors. The design targets existing large reactors, new water-cooled builds, small modular reactors, and research reactors, with commercialization expected through licensing and royalties rather than owned fuel production.
Work remains pre-commercial. Current activity centers on fabrication development, irradiation testing, post-irradiation examination, modeling, and eventual lead test rods or assemblies, with Idaho National Laboratory as the main development venue.
Execution depends on sustained funding, access to national-lab facilities, HALEU supply, regulatory approvals, and cooperation with utilities and incumbent fuel manufacturers. Conventional uranium dioxide fuel and accident-tolerant fuel programs frame the competitive category.
