Company Overview

Lightbridge Corporation is a leading nuclear fuel technology company dedicated to the development and commercialization of next-generation metallic fuel designs. The organization operates on the foundational belief that increasing the supply of reliable, zero-emission electric power is a global necessity for economic flourishing and climate stability. The company’s primary innovation, Lightbridge Fuel™, is engineered to fundamentally transform the safety and economic profiles of both existing large-scale light water reactors and the emerging generation of small modular reactors (SMRs).

The technological core of the organization is a proprietary metallic fuel made of a uranium-zirconium alloy, which is distinct from the traditional ceramic uranium dioxide (UO2) fuel used in the majority of today’s nuclear power plants. This metallic composition, coupled with a unique helical multi-lobe geometry, is designed to allow reactors to operate at significantly lower internal temperatures—approximately 1,000°C cooler than standard fuel—thereby enhancing safety margins and reducing the risk of core melt during accident scenarios.

Operationally, the company manages its business as a single segment focused on the high-value research, development, and eventual licensing of this intellectual property. It maintains a “capital-light” model, leveraging strategic partnerships with the United States Department of Energy (DOE) and national laboratories, particularly Idaho National Laboratory (INL), to conduct advanced fabrication and irradiation testing.

• The company’s technology aims to enable power uprates of up to 30% in existing and new reactors.
• Lightbridge is included in the Russell Microcap Index.
• The organizational culture prioritizes diversity, inclusion, and social justice as part of its climate mission.

Business Segments

The organization views its operations and manages its business as one primary segment: the development and commercialization of its proprietary nuclear fuel technology. This focus encompasses all stages of the technology’s lifecycle, from theoretical modeling to physical testing and regulatory engagement.

Nuclear Fuel Technology Development

The scope of this segment includes the design, engineering, and testing of metallic fuel for water-cooled reactors. While the technology is applicable across different reactor types, the operational effort is concentrated on two main applications:

• Existing Light Water Reactors (LWRs): Retrofitting the current global fleet to improve economics and extend fuel cycles from the standard 18 months to 24 months.
• Small Modular Reactors (SMRs): Providing a baseline fuel for new reactor designs to enhance load-following capabilities with intermittent renewable energy sources.

The segment’s performance is currently measured by technical milestones rather than sales. In 2024, significant progress was made at Idaho National Laboratory, including the successful demonstration of a proprietary co-extrusion process to produce an eight-foot-long fuel sample.

• 100% of the company’s internal resources are dedicated to this single technology segment.
• The segment relies on a licensing-and-royalty business model for future commercial revenue.

History and Evolution

The lineage of the organization began on January 8, 1992, with the incorporation of Thorium Power, Inc. in the state of Delaware. This early entity was focused on developing thorium-based fuel cycles intended to improve nuclear safety and proliferation resistance.

A major structural transformation occurred on October 6, 2006, when Thorium Power, Ltd. (a Nevada corporation founded in 1999) merged with the Delaware entity. Following this merger, the company transitioned its primary focus toward the development of metallic nuclear fuels that could be integrated into the existing global fleet of light water reactors. On September 29, 2009, the organization officially changed its name to Lightbridge Corporation to reflect this broader strategic mission.

Since 2018, the company has increasingly focused on the U.S. market and domestic energy security. This shift was underscored by the formation (and subsequent dissolution) of a joint venture with Framatome and the establishment of a multi-year partnership with the DOE’s national laboratory system. In January 2025, the company signed a memorandum of understanding with Oklo Inc. to explore co-locating fuel fabrication facilities, marking a new chapter in its commercialization pathway.

• The company was originally founded with a focus on thorium-based proliferation resistance.
• Strategic rebranding to Lightbridge occurred in 2009 to signal a shift to metallic fuel for LWRs.
• The organization has held a consistent leadership team since its 2006 merger.
