Simulation of the MIXA-06 Experiment by SIMMER-3

Cao, X.; Tobita, Yoshiharu

MIXA-06 experiment performed at Winfrish Technology centre in which 3 kg of molten fuel simulant (81% uranium and 19% molybdenum metal at a temperature of 36000 K) were released into water is selected to esti- mate the fragmentation model in SIMMER-III code on the mixing region in thecase of low Weber numbers in this study. The comparison of the front advancement of the melt droplet stream between the simulation and the experiment suggests that the currently employed hydrodynamic fragmentation model in SIMMER-III underestimates the fragmentation ra-te of the droplets in the simulation with low Waber numbers. The further investigation shows the fragmentation model based on thermal fragmentation mechanism is required.
