About LTBR
Lightbridge Corporation is a nuclear fuel technology development company. The Company is developing Lightbridge Fuel, a proprietary next-generation nuclear fuel technology for existing light-water and pressurized heavy-water reactors, significantly enhancing reactor safety, economics, and proliferation resistance. The Company is also developing Lightbridge Fuel for new small modular reactors (SMRs) to deliver the same benefits, plus load-following with renewables, on a zero-carbon electric grid. The Company is developing next generation nuclear fuel for water-cooled reactors that could improve the economics and safety of existing and new nuclear power plants, large and small, and enhance proliferation resistance of spent nuclear fuel while supplying clean energy to the electric grid or to behind the meter customers for electric power, including data centers. Its segment includes nuclear fuel technology.
