US-Canada firms tie-up to advance thorium nuclear fuel testing in reactors

Clean Core Thorium Energy (CCTE) has signed a fabrication agreement with BWXT Canada to advance the commercial demonstration of its thorium-uranium nuclear fuel technology. Announced in Chicago on August 3, the agreement will enable full-scale bundles to be manufactured at Canadian Nuclear Laboratories’ Chalk River Laboratories in Canada. BWXT Canada will provide qualified bundle hardware, while CNL will produce the fuel pellets and assemble reactor-representative bundles for irradiation in an operating reactor. The program aims to generate performance data needed for regulatory qualification and future commercial deployment across compatible nuclear plants. Three partners complete manufacturing pathway The agreement assigns distinct fabrication tasks to each organization. CCTE will provide the fuel design and material specifications, BWXT Canada will supply component hardware through its existing manufacturing quality-assurance program, and CNL will fabricate the pellets and complete the final bundle assembly under established nuclear standards. This division of work completes the capabilities needed to move the technology from a validated fuel design to full-size bundles suitable for demonstration irradiation. It also gives the program access to Canadian manufacturing infrastructure and expertise in fuel used by pressurized heavy-water reactors. “Sourcing materials from BWXT Canada represents an important step forward in demonstrating the viability of ANEEL fuel in existing reactor systems,” said Mehul Shah, CEO and Founder of Clean Core Thorium Energy. “Their decades of expertise in safe and reliable fuel fabrication, combined with deep experience with CANDU technology, combine to build a strong foundation for advancing our mission to deliver safer, more efficient nuclear energy solutions,” he added. Irradiation data to support qualification Once assembled, the bundles will enter a demonstration irradiation program intended to measure how the fuel performs inside a working reactor. The resulting evidence will support regulatory review, manufacturer qualification and deployment across compatible reactor platforms. CCTE designed the thorium and enriched-uranium combination to fit existing fuel formats and use current infrastructure. In pressurized heavy-water reactors, the company says it can serve as a drop-in replacement without changes to the reactor or core design, potentially reducing the cost and complexity of adoption. It could support Generation IV systems and light-water reactors. Its design targets better fuel utilization, higher burnup, longer refueling cycles, stronger safety margins, and reduced volumes of long-lived spent fuel for each unit of electricity generated. Earlier tests establish technical foundation The fabrication program follows accelerated irradiation tests conducted at Idaho National Laboratory’s Advanced Test Reactor in the United States. During those tests, experimental fuel rodlets achieved burnups above 60 gigawatt-days per metric ton of uranium, providing physical data on high-burnup operation. CCTE also published a peer-reviewed engineering assessment in Nuclear Engineering and Design. According to the company, the study examined performance, safety characteristics and compatibility across several reactor applications. Together, the testing, engineering analysis and Canadian fabrication agreement create the experimental and manufacturing foundation for a commercial demonstration. The next phase will determine whether full-scale bundles can reproduce the expected performance inside an operating reactor and provide regulators and potential operators with evidence required for broader use.
