| Abstract Scope |
Understanding the microstructural evolution of nickel-rich austenitic alloy 800H under irradiation conditions is essential for accelerating the deployment of advanced nuclear reactors. We are developing a predictive tool incorporating ion irradiation and computational materials modeling to determine this microstructure evolution that are benchmarked against reactor data on the same alloys. The following work involves the expansion of a cluster dynamics code, Xolotl, modeling prismatic loop evolution at different irradiation temperatures and dose values for both ion and neutron irradiation conditions. Loop sizes and densities will be compared to current experiment results. |
