Fission products (FPs) generated during severe accidents in light water reactors (LWRs) migrate over a wide area and are considered to have a significant impact on contamination inside and outside the reactor. Therefore, accurate prediction of FP behavior during accidents is considered to be important for reactor safety assessment.
In this study, the TeRRa-CsOH experimental analysis was performed using the FP behavior analysis code FIPRA to evaluate the wall adsorption behavior of FP.
