Lightbridge and Studsvik Scandpower have entered into a partnership to develop an extension of the Studsvik CMS5 Core Management Suite to model the new Lightbridge Fuel design. Together, Lightbridge and Studsvik will provide the commercial nuclear sector with a software package for light water reactors that is fully supported by the Studsvik software already adopted by customers around the world.

Lightbridge announced that it has received a notice of allowance from the United States Patent and Trademark Office for U.S. Patent Application No. 18/383,668, titled "Fuel Assembly." The application covers 16 claims directed to fuel assemblies and nuclear reactors incorporating Lightbridge's proprietary spirally twisted, multi-lobed fuel element technology, designed for pressurized heavy-water reactors, including CANDU-type designs. The allowed claims describe a fuel assembly comprising a plurality of elongated fuel elements, each having a spirally twisted, multi-lobed profile that defines a plurality of spiral ribs. Each fuel element includes a fuel kernel with fissile material disposed in a matrix of metal non-fuel material, surrounded by cladding, with a moderator-to-fuel ratio of 2.4 or less. The patent encompasses both the fuel assembly itself and a nuclear reactor incorporating the assembly in a pressurized heavy water reactor.
