The necessary short development time and testing of accident tolerant fuel concepts for light water reactors requires the incorporation of computational modeling and analysis that can quantify performance in normal and transient conditions. This presentation will focus on a multiscale approach to developing a first principles understanding for the development of key material behavior and constititutive models for radiation-induced degradation, and then apply these models into the engineering scale fuel performance code BISON to assess concept performance. Particular emphasis in this presentation will be on the radiation strengthening of FeCrAl alloys, as well as the radiation-induced swelling of SiC composite cladding, especially in cases where the experimental database is incomplete at this time. BISON fuel performance modeling assessments will be discussed that assess the performance of FeCrAl or SiC fuel rods, and identify ways to improve the ATF design.
