CNL to manufacture test bundles of thorium-based fuel
Canadian Nuclear Laboratories has signed an agreement with Chicago-based Clean Core Thorium Energy to manufacture demonstration irradiation bundles of Clean Core’s ANEEL (Advanced Nuclear Energy for Enriched Life) fuel. The fuel is made with a combination of thorium and high-assay low-enriched uranium and is designed for use in pressurized heavy water reactors, such as Canada’s CANDU fleet.
