Advanced Nuclear Fuel Technology · Nasdaq: LTBR
Lightbridge is developing Lightbridge Fuel™, a proprietary next-generation nuclear fuel technology for current and future reactors, enhancing the economics, proliferation resistance and safety of nuclear power — operating about 1,000°C cooler than standard fuel.
Discover the SecretAbout Lightbridge
Lightbridge Corporation is a publicly-traded company headquartered in Reston, Virginia. We're advancing state-of-the-art fuel technology with the potential to transform the safety, economics and efficiency of nuclear power plants — and we advise emerging nuclear markets on implementing nuclear generation plans.
Get to Know Lightbridge
What Is the Secret?
Nuclear power already provides ten percent of the world's electricity and is set to grow significantly in the coming decades — delivering global energy security and combating climate change with virtually zero carbon emissions. Renewables like wind and solar are important, but they can't provide the 24/7 reliability that consumers and businesses demand. Current fuel rods have barely changed in design for decades; Lightbridge reimagined the nuclear fuel rod using advanced technology to make it safer and more economical, without compromising on quality.
Lightbridge Fuel™ Performance
Key Highlights
Lightbridge Fuel™ is designed to work in both new and existing reactors.
Less spent fuel per plant output, and the spent fuel is useless for weapons purposes.
Internal temperature runs 1,000°C cooler than current fuel, avoiding hydrogen generation in design-basis accidents.
Increases power output, extends the fuel cycle, and offers the lowest cost to add reliable electricity to the grid.
Also in development for small modular reactors, adding load-following with renewables on a zero-carbon grid.
Four large electric utilities generating about half of US nuclear power advise Lightbridge on fuel development.
Unique Features
With Lightbridge Fuel™, a reactor can produce more power at a lower temperature, thanks to two unique features: an increased coolant flow rate — achieved by removing flow-restricting spacer grids so more water moves through the core without extra pump power — and increased fuel surface area, which raises safety margins and lets the fuel generate more heat.
Proliferation Resistance
Lightbridge Fuel™ uses an initial enrichment of just 15–20%, giving it the lowest strategic value for proliferation of any comparable fuel. It also contains significantly less plutonium than conventional uranium oxide fuel and consumes more uranium during its operating cycle — and any plutonium present in the spent fuel is considered "useless" for nuclear weapons, according to a 2018 peer-reviewed study published in Nuclear Engineering and Design.
Market Need
Backing the Nuclear Renaissance
Lightbridge commended the U.S. Department of Energy's launch of UPRISE — the Utility Power Reactor Incremental Scaling Effort — aimed at expanding U.S. nuclear capacity by maximizing existing reactor output, restarting dormant facilities, and extending reactor lifespans. UPRISE targets 2.5 GW of additional nuclear capacity by 2027 and 5 GW by 2029, and Lightbridge Fuel™ is being designed to deliver meaningful power uprates with enhanced safety margins to support exactly that kind of national effort.
Strategic Partnerships
Two long-term framework agreements with Battelle Energy Alliance, DOE's operating contractor for INL, plus two DOE GAIN program vouchers.
A Memorandum of Understanding to evaluate co-locating a Lightbridge fuel fabrication facility within Oklo's planned advanced fuel manufacturing site.
A partnership to extend the Studsvik CMS5 Core Management Suite so it can model the Lightbridge Fuel™ design for commercial LWR customers.
Business Model
Lightbridge operates under a licensing and royalty model, independently validated and based on the increased power generated by Lightbridge-designed fuel and a high ROI for operators of existing and new reactors. For countries and organizations seeking to launch or expand a nuclear energy program, our team of experts writes a roadmap to success that considers national and international goals — including developing the strategic plan for commercial nuclear power in the United Arab Emirates.

Newsroom
In the Media
Lightbridge CEO Seth Grae's speech, "Fueling Nuclear Energy's Global Growth," was featured on the cover of Vital Speeches International. Lightbridge also publishes a monthly newsletter and technical articles covering fuel research, conference presentations and industry policy — including the July 2026 Lightbridge Newsletter and photos from the INL assembly experiment.
Investor Documents
Leadership
Seth Grae, Chairman and CEO, has led Lightbridge since its formation in 2006 and has advised governments on national nuclear power strategy, including developing the strategic plan for commercial nuclear power in the United Arab Emirates. He is supported by a management team of nuclear engineering and finance veterans, including CFO Larry Goldman and Executive Vice President Dr. Andrey Mushakov, plus a Board of Directors and Senior Advisors guiding diplomacy, policy and commercialization.
View Management TeamNuclear power must play a central role if the world is to meet its energy and climate goals at the scale required.
Our recent agreements and lab partnerships keep Lightbridge Fuel™ on track toward commercial reactor demonstration.
Our balance sheet gives us the runway to keep funding fuel qualification work through commercial demonstration.
Every stage of qualification testing brings Lightbridge Fuel™ closer to a licensable, commercial-ready design.
Global Reach
Lightbridge's patent portfolio spans more than 15 jurisdictions, including the United States, United Kingdom, Germany, France, China, Japan, Korea, Australia, Canada, India, Sweden, Finland, Turkey, Bulgaria, Czech Republic and the Eurasian Patent Organization — safeguarding the intellectual property behind Lightbridge Fuel™ as it moves toward commercialization.
Made in America
Headquartered in Virginia, Lightbridge is creating nuclear fuel technology capable of addressing the world's energy and climate needs. Lightbridge invented, patented and has independently validated the technology, including successful demonstration of the fuel in a research reactor, with plans to demonstrate it under commercial reactor conditions — assembling a world-class development team that includes veterans of leading global fuel manufacturers.
Corporate Governance
Lightbridge's Board of Directors oversees that the Company's assets are properly safeguarded, that appropriate financial and other controls are maintained, and that the business is conducted wisely and in compliance with applicable laws and proper governance — including oversight of the risks inherent in developing and commercializing new nuclear fuel technology.
Global Advisory Network
Four large electric utilities that generate about half of all US nuclear power already advise Lightbridge on fuel development and deployment. Beyond the utility sector, Lightbridge has served in advisory roles to governments developing or expanding nuclear power programs — from initial feasibility studies through procurement and operations — and its Senior Advisors counsel management on diplomacy, policy and commercialization.
