Core offering

Lightbridge Corporation is developing Lightbridge Fuel™, a proprietary next-generation nuclear fuel technology based on an enriched uranium-zirconium alloy designed for current pressurized water reactors, CANDU-type heavy water reactors, and next-generation small modular reactors. The fuel operates approximately 1000°C cooler than standard fuel and features a spirally twisted, multi-lobed fuel element with three radial zones manufactured via additive manufacturing, targeting commercialization through licensing to nuclear utilities around 2033–2035.

Product overview

Lightbridge Corporation is an advanced nuclear fuel technology company developing a single proprietary product: Lightbridge Fuel™. This next-generation nuclear fuel technology is designed for both existing and future reactor designs (including pressurized water reactors and CANDU-type heavy-water reactors). The technology aims to enhance reactor economics, proliferation resistance, and safety characteristics. The company operates at pre-commercial stage with ongoing irradiation testing at Idaho National Laboratory as part of its regulatory licensing pathway toward commercial deployment.

Partnerships

Seven partnerships are on record, tiered core, strategic and minor.

• Penn State UniversitycoreStrategic or Co-development Partner · 25 March 2026Selected to serve on Industry Advisory Board of $6 million DOE-funded nuclear materials research project (BTN2M2). The four-year project establishes a multi-university consortium to study nuclear materials at micro-scale. Lightbridge focuses on studying irradiation behavior of cladding materials relevant to its Lightbridge Fuel technology.
• Idaho National Laboratory (INL)coreStrategic or Co-development Partner · 1 November 2025Public-private partnership with Idaho National Laboratory for irradiation testing of Lightbridge Fuel samples at the Advanced Test Reactor. INL conducted the FAST (Fission Accelerated Steady-state Testing) irradiation method. The first batch of irradiated fuel samples was successfully removed on May 6, 2026, marking a key validation milestone.
• Oklo Inc.strategicStrategic or Co-development Partner · 28 January 2025Signed Memorandum of Understanding to explore collaboration on co-locating a fuel fabrication facility and recycling nuclear waste. The collaboration aims to improve nuclear energy sustainability and reduce operational costs through used fuel recycling and reprocessing.
• Stern LaboratoriescoreTechnology or IntegrationEngineering contract signed March 17, 2026, to evaluate thermal and hydraulic performance of Lightbridge Fuel for light water reactors. Phase 1 work expected to take approximately one year at Stern's Ontario facility, supporting U.S. regulatory licensing efforts.
• Curio Legacy VenturesminorStrategic or Co-development PartnerPartnership with Curio for potential used nuclear fuel recycling and reprocessing collaboration, in addition to Curio's NuCycle technology for waste recycling and advanced reactor solutions.
• X-Energy, Westinghouse Electric Company, Kairos PowerminorStrategic or Co-development PartnerFellow advisory board members alongside Lightbridge on the Penn State DOE-funded nuclear materials research project, representing the advanced nuclear reactor ecosystem.
• OranominorStrategic or Co-development PartnerStrategic partnership referenced in context of Curio's funding, suggesting broader industry collaboration in the nuclear fuel cycle ecosystem.

Scale indicators7 records

Recent moves6 records

Expansion highlights6 records

Broad incumbents

• Westinghouse Electric Company: Westinghouse is the incumbent nuclear reactor OEM and fuel supplier, with significant market share in PWR fuel and active development of accident-tolerant fuel. It is a fellow advisory board member on the Penn State DOE project and represents the established competitor Lightbridge must displace or partner with.
• Holtec International: Holtec is a nuclear industry supplier providing spent fuel storage, transportation, and reactor decommissioning, with growing involvement in SMR development. Comparable to Lightbridge as a privately-held U.S. nuclear technology company pursuing adjacent parts of the fuel cycle.

Emerging players

• X-Energy: X-Energy is developing the Xe-100 high-temperature gas reactor and TRISO fuel. It is a fellow advisory board member on the Penn State DOE BTN2M2 project and represents an adjacent advanced fuel / advanced reactor company whose TRISO pathway partially overlaps with Lightbridge's metallic fuel ambitions.
• NuScale Power: NuScale is the leading small modular reactor developer with NRC design certification. It is comparable to Lightbridge as an advanced nuclear technology company targeting the next-generation reactor market and serves as a potential fuel customer as SMRs move toward deployment.
• TerraPower: TerraPower is developing the Natrium sodium-cooled fast reactor and traveling wave reactor concepts, and is actively pursuing advanced fuel supply partnerships. It is comparable to Lightbridge as a Bill Gates-backed advanced nuclear venture with significant capital and government engagement.
• Kairos Power: Kairos Power is developing the FHR molten-salt-cooled reactor using TRISO fuel. As a Penn State advisory board peer, Kairos represents another advanced reactor developer whose fuel demand could become a customer opportunity for Lightbridge if its metallic fuel is qualified for non-PWR applications.
• Curio Legacy Ventures: Curio is developing next-generation nuclear fuel recycling and reprocessing technologies. As Lightbridge's MOU partner for used fuel recycling, Curio is a comparable emerging player focused on advanced fuel cycle innovation with similar pre-revenue, partnership-driven commercialization profile.
• Oklo Inc. Oklo is an advanced reactor developer (Aurora microreactor) and Lightbridge's MOU partner for co-located fuel fabrication and used fuel recycling. As a peer, Oklo is both a potential customer for advanced fuel and a fellow advanced nuclear technology company pursuing NRC licensing.

Direct peers

• Framatome: Framatome is a global nuclear fuel manufacturer and reactor services provider, producing UO2, MOX, and increasingly advanced fuel designs. It competes directly with Lightbridge in supplying enriched fuel to pressurized water reactor operators worldwide and is developing its own advanced fuel concepts.
• BWX Technologies (BWXT): BWXT manufactures nuclear fuel components and provides reactor services for U.S. Navy and commercial nuclear plants. It is the most direct competitor to Lightbridge in advanced nuclear fuel fabrication, particularly for metallic and non-LWR fuel forms targeting government and commercial customers.
