"This Notice of Allowance further strengthens our U.S. intellectual property portfolio, particularly for our multi-lobed fuel element design optimized for pressurized heavy water reactors," Lightbridge (LTBR [https://seekingalpha.com/symbol/LTBR]) President and CEO Seth Grae said. "The CANDU reactor fleet represents a significant global market opportunity, and this patent further reinforces our technology’s applicability to heavy-water reactor designs."
