South Korea Grants Lightbridge Key Patent for Metallic Nuclear Fuel Design

MCLEAN, Va., June 4, 2015 (GLOBE NEWSWIRE) -- Lightbridge Corporation (Nasdaq:LTBR), a leading innovator of nuclear fuel designs and provider of nuclear energy consulting services, today announced that the Korean Intellectual Property Office has approved and issued to Lightbridge a key patent covering the Company's multi-lobed metallic fuel rod design and fuel assemblies. Patent No. 10-151116 – "Nuclear Reactor (Variants), Fuel Assembly Consisting of Driver-Breeding Modules for a Nuclear Reactor (Variants) and a Fuel Cell for a Fuel Assembly" – expands international protection of Lightbridge's proprietary fuel technology with indicated benefits of enhanced reactor safety and improved operating economics.

"The South Korean patent is another important milestone in the development of our fuel assembly designs for existing and new build pressurized water reactors," said Seth Grae, Lightbridge President and Chief Executive Officer. "Korea represents a significant potential market for Lightbridge metallic fuel with 24 operating pressurized water reactors and an additional 12 reactors either under construction or planned by 2035, according to the most current data compiled by the World Nuclear Association."

South Korea also is an active exporter of nuclear power reactors, marketing its units in the Middle East, North Africa and Southeast Asia. The South Korean Ministry of Trade, Industry and Energy aims to export 80 reactors worth $400 billion by 2030, the association reports.

The advantages of Lightbridge's metallic fuel design were confirmed in independent third-party analyses published in 2012 and 2013, Grae added. These reports, which include a peer-reviewed article published in Nuclear Technology, are available for download at He said the indicated benefits of Lightbridge's fuel include:

  • A 1,000°C reduction in average fuel operating temperature, compared to conventional uranium dioxide pellet fuel, resulting in dramatic safety improvements;
  • Improved heat transfer and fluid flow, increased structural strength, and improved performance during transients and accidents;
  • 10% more power and longer fuel cycles or up to 17% more power with the same fuel cycle length for existing pressurized water reactors (PWRs);
  • Up to 30% more power with the same fuel cycle length for new build PWRs;
  • Increased revenue and improved profit margins for existing nuclear power units;
  • Lower total levelized cost per kilowatt-hour for new build reactors;
  • Increased competitiveness of nuclear power versus fossil or renewable energy sources;

The commercial nuclear energy industry is projected to grow rapidly at a time of rising global demand for reliable, carbon-free, base load electric power. There are currently 437 operable civil nuclear reactors in 30 countries around the world, with 66 reactors under construction and 490 on order, planned or proposed, according to the World Nuclear Association. By 2040, the International Energy Agency projects a 58% increase in nuclear capacity from a combination of power uprates and reactor construction.

In April 2015, the nuclear fuel managers at Dominion Generation (NYSE:D), Duke Energy (NYSE:DUK), Exelon Generation (NYSE:EXC) and Southern Company (NYSE:SO) asked the U.S. Nuclear Regulatory Commission (NRC) to prepare to review Lightbridge's fuel design, in advance of an expected application in 2017 to use the Company's fuel in a U.S. reactor as early as 2020. The NRC relies on communications from U.S. utilities to adjust Commission staffing levels and budgets in anticipation of regulatory review of licensing applications.

"This formal expression of interest by major U.S. utilities is the strongest endorsement to date of Lightbridge fuel by potential customers," Grae said. The Commission posted the utilities' expression of interest in Lightbridge's fuel and supporting documents on its official web site at
