Lightbridge and Pacific Northwest National Laboratory Complete Work Under U.S. Energy Department GAIN Voucher to Advance a Critical Stage in Lightbridge Fuel Manufacturing Process

RESTON, Va., Feb. 27, 2023 (GLOBE NEWSWIRE) -- (Nasdaq: LTBR), an advanced nuclear fuel technology company, announced today that it has successfully completed work under the U.S. Department of Energy’s (DOE) Gateway for Accelerated Innovation in Nuclear (GAIN) voucher program to support the development of Lightbridge Fuel, in collaboration with Pacific Northwest National Laboratory ().

Working in collaboration with PNNL, the project scope was to demonstrate Lightbridge’s nuclear fuel casting process using depleted uranium, a key step in manufacturing Lightbridge Fuel. Several castings were performed throughout the project, and the cast ingots were analyzed. In an iterative process, the casting methodology was modified based on the characterization results as part of the process was a demonstration to achieve acceptable results with PNNL’s existing equipment. The results of this work will help Lightbridge determine a final process suitable to produce fuel material coupons for our upcoming irradiation tests in the Advanced Test Reactor.

, PNNL nuclear industry program manager, commented, “One of our missions at PNNL is to support U.S. nuclear industry partners in advancing their technology. Working on this GAIN-funded project was an excellent opportunity to use national laboratory resources and expertise on these fuel development efforts for light water reactors.”

Seth Grae, President and CEO of Lightbridge, commented, “Completing the work under our second GAIN voucher advances our ability to develop, demonstrate, and optimize the manufacturing processes for Lightbridge Fuel.”

“I want to thank the teams at Lightbridge and PNNL for their collaborative efforts. Our successful collaboration with the GAIN Office at the U.S. Department of Energy and access to U.S. national laboratories’ teams of experts and world-class facilities enabled Lightbridge to make meaningful progress in our fuel development program,” concluded Mr. Grae.
