Lightbridge Receives Notice of Allowance on Key Patent for its Metallic Nuclear Fuel in South Korea

RESTON, Va., July 19, 2017 (GLOBE NEWSWIRE) -- Lightbridge Corporation (NASDAQ:LTBR), a U.S. nuclear energy company, today announced that it has received a Notice of Allowance from the Korean Intellectual Property Office ("KIPO") for a key divisional patent covering two major inventions: (1) Lightbridge's innovative metallic fuel assembly design for Western-type pressurized water reactors incorporating four-lobe, helically twisted metallic fuel rods, and (2) the company's proprietary manufacturing method for metallic fuel rods using powder metallurgy. The patent is expected to be issued once the registration fee has been paid by Lightbridge.

Lightbridge's growing patent assets in the U.S., European Union, China and South Korea, among other nuclear markets, are another milestone towards the full-scale deployment of fuel assemblies based on the Lightbridge metallic fuel design.

"This latest patent expands the scope of our patent protection in South Korea, an important world nuclear market and a global supplier of nuclear technology," said Seth Grae, President and CEO of Lightbridge Corporation. "South Korea remains the world's fifth-largest user of nuclear energy, with more than 22 gigawatts of installed capacity producing about a third of its electricity. By expanding Lightbridge's worldwide patent portfolio, including in South Korea, Lightbridge is positioning itself to meet the fuel demands of the world's major nuclear markets."

South Korea has 24 nuclear power reactors in operation—including Shin Kori 3, the country's newest unit, an APR1400 that went online in December 2016. Three additional APR1400 units are under construction in South Korea. In the United Arab Emirates, a consortium led by Korea Electric Power Corporation is constructing four APR1400 units, the first of which was completed in May 2017. KEPCO is also in advanced negotiations to pursue the construction of APR1400 units in the United Kingdom, according to recent media reports.

"Lightbridge metallic fuel could be particularly attractive in South Korea. It can produce up to 30 percent more power than existing fuel in new reactor designs, while reducing operating costs and enhancing the safety of existing nuclear reactors," Grae said.
