Title: Rate theory scenarios study on fission gas behavior of U 3Si 2 under LOCA conditions in LWRs

Abstract

Fission gas behavior of U 3Si 2 under various loss-of-coolant accident (LOCA) conditions in light water reactors (LWRs) was simulated using rate theory. A rate theory model for U 3Si 2 that covers both steady-state operation and power transients was developed for the GRASS-SST code based on existing research reactor/ion irradiation experimental data and theoretical predictions of density functional theory (DFT) calculations. The steady-state and LOCA condition parameters were either directly provided or inspired by BISON simulations. Finally, due to the absence of in-pile experiment data for U 3Si 2’s fuel performance under LWR conditions at this stage of accident tolerant fuel (ATF) development, a variety of LOCA scenarios were taken into consideration to comprehensively and conservatively evaluate the fission gas behavior of U 3Si 2 during a LOCA.
