Lightbridge
🇺🇸 Reston, US · Active
Lightbridge Corporation is a publicly traded US company (Nasdaq: LTBR) headquartered in Reston, Virginia. It is developing Lightbridge Fuel, a proprietary nuclear fuel design for current and future reactors that it says runs about 1,000 °C cooler than standard fuel because of a larger fuel surface area and higher coolant flow, allowing more power and longer fuel cycles. The company describes the fuel as still in research and development, with testing planned through third parties including US national laboratories. It also advises countries starting nuclear power programmes.

Terms
- High-assay low-enriched uranium
- High-assay low-enriched uranium: uranium enriched to between 5% and just under 20% uranium-235, as the US Department of Energy defines it. It is still formally low-enriched, because the international line for highly enriched uranium is 20%, which is why many designs specify 19.75%. The binding supply constraint for many advanced reactor designs. The 5 to 10% part, which carries lighter US physical-security requirements than material from 10% up, is also tagged as LEU+. A developer calling fuel in that band 'LEU' is making a labelling choice, not describing a different enrichment.
