Advanced Fuels

Coatings- development of Cr cold spray–coated fuel cladding with enhanced accident tolerance. Accident-tolerant fuels (ATFs) are currently of high interest to researchers in the nuclear industry and in governmental and international organizations.
Probabilistic view and Composites of SiC/SiC cladding, failure based on full core thermo-mechanical response. The numerical model for mechanical calculation of multi-layer claddings in FRAPCON 4.0. Failure probabilistic analysis methodology of SiC/SiC composite cladding. Fuel performance analysis and the failure probabilistic assessment in full core. Influence of relocation recovery on failure probability of SiC-based cladding. Fuel performance optimization of U3Si2-SiC design during normal, power ramp and RIA conditions. U3Si2 properties were implemented in FRAPCON and FRAPTRAN. Gap size optimization was conducted for U3Si2-SiC to minimize SiC failure risk. Radial average fuel enthalpy limits for U3Si2-SiC design at variable burnup were recommended.
