Evaluation of TEXAS-V break up models against experimental data

This paper presents the results of TEXAS-V computer code simulations of FARO L-14, L-28, and L-33. The old break up model and new break up model are exercised for the comparative simulations. As these experimental data set cover a wide range of ambient pressure, sub-cooling of the water pool, and the melt jet diameters, the results of the simulation will be beneficial in assessing the TEXAS-V code capability in predicting the steam explosion phenomena in prototypic reactor case. As it turned out that current model had some deficiencies, the modules for the fragmentation, equation of state, and interfacial area for each flow regime in TEXAS-V are improved for the simulation of FARO L-28 and FARO L-33.
