60 Years of U: Perspectives on resources, demand, and the evolving role of nuclear energy
Recent years have seen growing global interest in nuclear energy and rising confidence in the sector. For the first time since the early 2000s, there is renewed optimism about the industry’s future. This change is driven by several major factors: geopolitical developments that highlight the need for secure energy supplies, a stronger focus on resilient energy systems, national commitments to decarbonization, and rising demand for clean and reliable electricity.

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.
