Lightbridge Corporation

Lightbridge Corporation is a publicly traded advanced nuclear fuel technology company headquartered in Reston, Virginia, USA. The company's core mission is to develop state-of-the-art fuel technology to enhance the safety, economics, and efficiency of nuclear power plants, contributing to carbon-free energy solutions globally.

Lightbridge's primary product is Lightbridge Fuel™, a proprietary next-generation nuclear fuel designed for existing light-water and pressurized heavy-water reactors, as well as new small modular reactors. This innovative fuel technology aims to significantly improve reactor safety, economics, and proliferation resistance, operating approximately 1,000°C cooler than standard fuel. It is projected to enable power uprates of up to 20% or more in existing reactors and 30% or more in new-build reactors, while also extending fuel cycle length and reducing spent fuel waste. Beyond fuel development, Lightbridge also offers consulting services to governments and organizations embarking on or expanding nuclear energy programs.

Led by President and CEO Seth Grae, Lightbridge Corporation continues to advance its technology, as evidenced by recent patent allowances in Europe, the U.S., and Canada for its metallic fuel assemblies and additive manufacturing methods. The company announced its Q1 2026 financial results on April 27, 2026, reporting increased research and development expenditures and a net loss, alongside a strong cash position. Lightbridge is actively collaborating with institutions like Idaho National Laboratory and Stern Laboratories Inc. on fuel development and testing, and is included in the Russell 2000® and Russell 3000® Indexes.
