RESTON, Va., Feb. 12, 2025 (GLOBE NEWSWIRE) -- Lightbridge Corporation (Lightbridge) (Nasdaq: LTBR), an advanced nuclear fuel technology company, today announced a significant milestone in its innovative nuclear fuel development efforts, successfully performing a co-extrusion demonstration of a coupon sample consisting of an alloy of depleted uranium and zirconium with an outer cladding made of nuclear-grade zirconium alloy material at Idaho National Laboratory (INL). The co-extrusion process demonstration conducted at INL entailed pressing the metallic alloy billet encased in zirconium alloy cladding through a die to produce a cylindrical rod with a length of approximately 8 feet.

The co-extrusion of this demonstration coupon sample represents a key fabrication milestone under Lightbridge’s Strategic Partnership Project Agreement with Battelle Energy Alliance LLC (BEA), the U.S. Department of Energy’s (DOE) operating contractor for INL.

The uranium-zirconium alloy used in the demonstration rodlet is the same composition that Lightbridge plans to use for its future commercial Lightbridge Fuel™ product. INL and Lightbridge will now work together to analyze the co-extruded coupon sample to confirm the extrusion process parameters.

These efforts pave the way for future production of coupon samples using enriched uranium, which will undergo capsule irradiation testing in INL's Advanced Test Reactor (ATR) under an existing Cooperative Research and Development Agreement between Lightbridge and BEA. This planned irradiation testing program, coupled with post irradiation examination activities whose scope is to be released via a future Project Task Statement, aims to generate critical irradiation performance data for Lightbridge’s advanced fuel and support regulatory licensing efforts for its commercial deployment.

“This milestone exemplifies the collaboration and innovation driving the advancement of Lightbridge Fuel,” said Ron Crone, INL Associate Laboratory Director. “The co-extrusion of this coupon sample leverages the capabilities of INL's Materials and Fuels Complex and underscores our commitment to advancing nuclear energy innovation. We are proud to support Lightbridge in this important work.”

Dr. Scott Holcombe, Vice President of Engineering at Lightbridge Corporation , added, “This successful co-extrusion demonstration is a testament to the continuous progress we have made over the past year on demonstration of our fuel fabrication process in our collaborative efforts with INL. By integrating the uranium-zirconium alloy with nuclear-grade cladding material, we’re advancing the safety, efficiency, and performance of nuclear fuel, bringing us closer to commercialization and real-world deployment.”
