Fuel Qualification Guidance for TRi-structural ISOtropic (TRISO) Fuel
Tristructural isotropic (TRISO)-coated particle fuel is foundational for many high-temperature reactor (HTR) designs, including high-temperature gas-cooled reactors (HTGRs) and fluoride salt-cooled high-temperature reactors (FHRs). The U.S. Department of Energy initiated the Advanced Gas Reactor Fuel Development and Qualification (AGR) Program in 2002 to establish U.S. capability to fabricate high-quality uranium oxycarbide (UCO) TRISO fuel and demonstrate its performance.

| U.S. NRC—CNSC Memorandum of Cooperation FINAL REPORT concerning Tristructural Isotropic (TRISO) Fuel Qualification) |
This report establishes a common regulatory position on TRISO fuel qualification based on existing knowledge and data and identifies potential design-dependent gaps that should be addressed to enable TRISO use in advanced reactor licensing applications. Specifically, this report summarizes data, criteria, and approaches that can help support fuel-related regulatory findings for TRISO-fueled reactor designs. Previously released interim reports are available at ML22030A000 and ML22101A297. |
