Lightbridge Advances Nuclear Fuel Development with Successful Enriched Uranium-Zirconium Alloy Fabrication.

Lightbridge, a US-based nuclear fuel company, has successfully fabricated coupon samples using enriched uranium-zirconium alloy, a critical step in the development of its next-generation Lightbridge Fuel product. This achievement marks a significant milestone in the company's efforts to create advanced nuclear fuel for testing. As a result, Lightbridge's stock price has risen by 3.1% in pre-market trading on Monday.

Lightbridge Corporation (Nasdaq: LTBR), a leader in advanced nuclear fuel technology, has successfully fabricated coupon samples using enriched uranium-zirconium alloy, a significant milestone in the development of its next-generation Lightbridge Fuel™ product. The samples, which are representative of the fuel material alloy composition Lightbridge plans to use in its commercial fuel product, have been extruded using the company's proprietary fabrication method [1].

The extrusion process was performed using Lightbridge's proven fabrication technology, previously demonstrated at the Idaho National Laboratory (INL), to extrude and co-extrude depleted uranium samples with zirconium-alloy cladding. This technology is now being applied to the enriched alloy for further development [1].

The enriched coupon samples will undergo irradiation testing at INL's Advanced Test Reactor (ATR) as part of an existing Cooperative Research and Development Agreement (CRADA) between Lightbridge and INL. This testing program is aimed at generating critical irradiation performance data to support Lightbridge's regulatory licensing and commercialization efforts for the deployment of Lightbridge Fuel™ [1].

The successful fabrication of these enriched uranium-zirconium alloy coupon samples is a critical step toward Lightbridge's goal of delivering a safer, more efficient fuel solution for the nuclear energy industry. This collaborative effort with INL will provide essential data to support Lightbridge's regulatory approval process [1].

As a result of this achievement, Lightbridge's stock price has risen by 3.1% in pre-market trading on Monday.
