Lightbridge Secures Key Patent for Nuclear Fuel Design in Canada — Lightbridge Corporation

Event summary

Lightbridge received a Notice of Allowance from the Canadian Intellectual Property Office for its nuclear fuel assembly design (Canadian Patent Application No. 2,960,383).
The patent covers 48 claims related to fuel assemblies with helically twisted fuel elements arranged in mixed grid patterns.
The patent application was originally filed in September 2015 and includes broader claims covering mixed grid patterns without specifying particular shapes.
The patent is particularly relevant to pressurized heavy water reactors, including Canada’s CANDU reactor fleet.

The big picture

Lightbridge’s patent approval in Canada strengthens its intellectual property portfolio in a key market with deep nuclear expertise. The patent is strategically relevant to Canada’s CANDU reactors, which are undergoing life extensions and could benefit from Lightbridge’s innovative fuel technology. This development positions Lightbridge to capitalize on Canada’s growing interest in small modular reactors and its commitment to zero-emission energy solutions.
