Lightbridge (LTBR) investor relations material

Strategic vision and market opportunity

• Aims to set a new global standard for nuclear fuel, offering major improvements in safety, performance, economics, waste reduction, and proliferation resistance compared to current fuels.

• Designed for both new and existing reactors, targeting a $20+ billion market.

• Enables less spent fuel per unit of power and spent fuel that is not usable for weapons.

• Supports grid flexibility and load-following, potentially replacing fossil fuel plants.

Technology and product features

• Operates nearly 1000°C cooler than conventional fuel, enhancing safety and reducing accident risks.

• Tri-lobe, helically twisted metallic fuel rods improve coolant mixing, heat transfer, and structural integrity.

• Absence of spacer grids reduces core pressure drop by up to 50%, enabling power uprates.

• Metallurgic bonding and increased cladding thickness enhance durability and reduce radiological risks.

Development milestones and partnerships

• Achieved key fabrication milestones, including successful co-extrusion of uranium-zirconium alloy with nuclear-grade cladding at Idaho National Laboratory.

• Initiated irradiation testing of enriched uranium-zirconium alloy fuel samples at INL's Advanced Test Reactor in November 2025.

• Collaboration with Oklo to explore co-location of fabrication facilities and joint nuclear waste recycling initiatives.
