Lightbridge Corp.

Lightbridge Corporation is an advanced nuclear fuel technology company headquartered in Reston, Virginia, developing proprietary next-generation fuel designs for both existing and future nuclear reactors. The company's core innovation, Lightbridge Fuel, uses a metallic fuel rod architecture that operates at significantly lower temperatures than conventional uranium oxide fuel, enhancing reactor safety margins and enabling higher power output from existing reactor infrastructure.

The Lightbridge Fuel design features a helically twisted, multi-lobed rod geometry that increases surface area for heat transfer and improves coolant flow around the fuel assembly. This architecture allows reactors to generate more power per fuel assembly while maintaining wider thermal safety margins. The fuel is designed as a drop-in replacement compatible with existing pressurized water reactors, meaning utilities can upgrade fuel performance without modifying reactor hardware.

Lightbridge collaborates with government research institutions and nuclear industry partners to advance its fuel technology through irradiation testing and materials qualification programs. The company's technology addresses multiple objectives within the nuclear energy sector, including improving the economics of existing reactor fleets, enhancing inherent safety characteristics and supporting nonproliferation goals through fuel designs that resist weapons-grade material diversion. Lightbridge trades on Nasdaq under the ticker LTBR.
