CNSC PERSPECTIVE ON CANDU FUEL THERMALHYDRAULIC DESIGN
13th International Conference on CANDU Fuel - 2016 Aug. 15-18
Y. Guo (Canadian Nuclear Safety Commission)
Fuel thermal hydraulics is one of the key aspects in reactor fuel and core design. To protect physical barriers to fission products release, fuel thermalhydraulic design must provide sufficient cooling to the fuel at each plant state, i.e., normal operation (NO), anticipated operational occurrences (AOOs), design basis accidents (DBAs), etc. The Canadian Nuclear Safety Commission (CNSC) has established regulatory requirements on fuel thermalhydraulic design. Regulatory guidance, commensurate with the regulatory requirements, was also developed to elaborate further on the requirements or to provide direction to licensees and applicants on how to meet the requirements. It also provides more information about how CNSC staff evaluate specific problems or data during their review of license applications of new fuel designs and modifications to the existing fuel designs. This presentation presents, at a high level, the Canadian regulatory requirements, guidance, and review criteria pertaining to CANDU fuel thermalhydraulic design.
