Several of the challenge problems in CASL required accurate nuclear fuel performance modeling capabilities for their solution, especially Pellet-Clad-Interaction (PCI) and Loss-of-Coolant-Accident (LOCA)/Reactivity-Insertions Accident (RIA). In order to address these challenge problems, CASL contributed to the development of the Bison fuel performance code and made significant investments in both capabilities and validation needed for the two challenge problems referenced above. In addition, CASL played a key role in developing Bison capabilities for Accident Tolerant Fuels (ATFs). Fuel performance modeling is closely tied to the underlying materials models. In several cases, CASL sought better models using multi-scale materials modeling and simulation techniques, which are particularly important for ATF concepts where experimental data is scarce. This panel session will discuss materials and nuclear fuel performance modeling performed in CASL. It will highlight historical perspectives, accomplishments, lessons-learned and remaining challenges.
