Lightbridge Corp. received a Notice of Allowance from the Japan Patent Office for its Multi-Zone Fuel Element. The patent covers the fuel's unique design and its additive manufacturing (3D printing) production method.
This intellectual property protection targets Japan, one of the world's largest nuclear power markets. The allowed claims cover a fuel rod design featuring three layers of different materials with varying thicknesses.
The multi-layer configuration aims to enhance reactor performance and safety margins. The patent also protects the specific 3D printing process used for manufacture.
CEO Seth Grae emphasized the commercial value of securing the fuel rod, assembly, and manufacturing process. Japan represents a key market for the company's energy security and decarbonization strategy.
