What LIGHTBRIDGE Corp does
In the company’s own words
Lightbridge Corporation (NASDAQ: LTBR) is a nuclear technology company developing next-generation metallic nuclear fuel designed to improve the economics, safety, and proliferation resistance of water-cooled nuclear reactors. The company's website is www.lightbridgecorp.com.
The company's core product, Lightbridge Fuel™, represents an advanced nuclear technology utilizing proprietary all-metal fuel with a helical geometry designed to enhance heat transfer properties compared to conventional uranium dioxide fuel. The fuel is engineered for use in pressurized water reactors, boiling-water reactors, Russian-designed VVERs, CANDU reactors, and small modular reactors. Lightbridge projects that its metallic fuel could enable power uprates of up to 30 percent in new-build reactors and up to 17 percent in existing large reactors while operating at significantly lower temperatures than conventional fuel.
Lightbridge's fuel development strategy centers on lead test assemblies in commercial reactors, with the company targeting demonstration in the early to mid-2030s and initial purchase orders from utilities in the late 2030s. The company conducts the majority of its research and development activities in collaboration with the U.S. Department of Energy's national laboratories, particularly Idaho National Laboratory. Key development milestones include irradiation testing of fuel material coupon samples, loop irradiation testing of prototype fuel rods, thermal-hydraulic experiments, and development of a dedicated fuel fabrication facility.
The company's intellectual property strategy combines patent protection in key commercial markets with trade secrets and proprietary know-how. Lightbridge maintains memberships in industry consortiums including the DOE's HALEU Consortium to address supply chain infrastructure needs for high-assay low-enriched uranium material.
Recent strategic developments include a memorandum of understanding with Oklo, Inc. regarding potential co-location of fabrication facilities and collaboration on spent fuel recycling, as well as collaborative agreements with specialty metals manufacturers and nuclear engineering software providers to support fuel development and modeling capabilities. The company is funded primarily through equity offerings via an at-the-market facility and government partnerships.
