MCLEAN, Va., Feb. 18, 2014 (GLOBE NEWSWIRE) -- Lightbridge Corporation (Nasdaq:LTBR), a leading innovator of nuclear fuel designs and provider of nuclear energy consulting services, today announced that the U.S. Patents and Trademarks Office (USPTO) has approved and issued to Lightbridge the key patent covering Lightbridge's multi-lobed metallic fuel rod design and fuel assemblies. The patent number is 8,654,917 and is available on the USPTO website at

"This new patent is the single most important patent in Lightbridge's intellectual property portfolio and is crucial to the Company's future royalty revenue stream," said Seth Grae, President and Chief Executive Officer. "We now have very broad protection for the metal fuel element that will be used in all of our fuel assembly designs. Moreover, this successful outcome secures patent protection in the U.S. – the world's largest market of pressurized water reactors currently in operation."

Lightbridge is developing and commercializing next generation nuclear fuel technology with benefits of improving the safety and economics of existing and new light water reactors. The Company has filed equivalent patent applications that are pending approval in several key countries in Europe and Asia.

"Lightbridge continues to achieve its major developmental milestones through the dedicated, significant high technology work of our extremely skilled team of nuclear engineers," Grae said. "We expect our success will translate into one or more teaming arrangements with major nuclear fuel fabricators and other strategic partners that may include cost-sharing contributions or revenue in the form of technology access fees to Lightbridge based on our intellectual property, as well as engineering support services."

In October 2013 the Company announced that it had signed a memorandum of understanding with the Babcock & Wilcox Company (NYSE:BWC) to evaluate constructing a pilot-scale fuel fabrication facility to demonstrate fabrication of Lightbridge-designed metallic fuel rods up to full length.

Unlike conventional fuel rods comprised of uranium oxide pellets that are stacked in zirconium alloy tubes, Lightbridge's proprietary multi-lobed metallic fuel rods are a solid uranium-zirconium alloy, extruded in full size lengths of 12 to 14 feet.

"Lightbridge's unique metallic fuel technology presents a compelling value proposition to a growing global industry," said James P. Malone, Lightbridge Chief Nuclear Fuel Development Officer. "Our patented metallic fuel rod design offers increased structural integrity and improved heat transfer while operating at nearly 1,000ºC cooler than conventional rods. It will deliver 10% to 17% more power from existing light water reactors and longer fuel cycles to nuclear utilities. These benefits will enhance safety, increase revenue and improve operating margins for both existing power units and new-build commercial reactors."
