RESTON, Va., March 19, 2026 (GLOBE NEWSWIRE) — Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, today announced that two of its technical managers and subject matter experts presented key research findings at the TMS2026 Annual Meeting & Exhibition in San Diego, California, one of the premier global conferences for materials science, metallurgy, and nuclear fuel technology.
Dr. Geoffrey (Boone) Beausoleil, Director of Materials at Lightbridge, held a talk titled “Metal Fuels Opportunities Beyond Sodium Fast Reactors,” co-authored with Dr. Scott Holcombe, Vice President of Engineering at Lightbridge. The presentation examined the expanding applicability of metallic fuel concepts to a broader class of advanced reactor designs beyond the sodium fast reactor systems that have historically anchored metal fuel development.
Dr. Kyle Paaren, Manager of the Fuel Performance Group at Lightbridge, held a talk titled “U-Zr Alloy Properties Review and Applicability to Lightbridge Corporation Fuel Performance Activities,” co-authored with Raymond Wang, P.E., Director of Licensing at Lightbridge, Dr. Beausoleil, and Dr. Holcombe. The presentation provided a comprehensive technical review of uranium-zirconium alloy properties and a significant milestone in Lightbridge’s fuel qualification pathway, demonstrating that the Company’s proprietary UZr₂ fuel can be accurately modeled and characterized through a newly validated, Lightbridge-specific framework built from real measured data from the Company’s own fuel material coupon samples.
Both presentations were delivered during the session on metal fuels, chaired by Professor Ericmoore Jossou of the Massachusetts Institute of Technology.
“As the research community continues to explore opportunities for advanced reactors and fuels, the materials science community has a real opportunity to extend the proven performance advantages of metallic fuels into a much wider set of applications,” said Dr. Beausoleil. “We are excited to be contributing to that conversation at TMS 2026.”
“Our U-Zr alloy work is foundational to everything we are building at Lightbridge,” said Dr. Paaren. “The properties data we presented directly informs how we model and validate fuel performance, and we are pleased to share that work with the broader materials science and nuclear fuel community.”
“Boone and Kyle’s presentations at TMS2026 reflect the world-class nuclear engineering expertise we have assembled at Lightbridge,” said Seth Grae, President and Chief Executive Officer of Lightbridge Corporation. “Their work advances the technical foundation of our fuel development program and reinforces Lightbridge’s position at the forefront of advanced nuclear fuel innovation.”
The TMS Annual Meeting, hosted by The Minerals, Metals & Materials Society, brings together leading researchers and practitioners across materials science and engineering disciplines. The TMS2026 conference program is available at www.tms.org/TMS2026.
