Station blackout (SBO) with steam-driven auxiliary feed water pump failure is selected as the case for the model comparisons analysis. The result shows that thermal resistance model between debris and concrete has much influence on the consequence of MCCI. The concrete erosion rate calculated with gas film model is much higher than that of slag film model. Some other model comparisons such as the chemical reaction heat and the configuration molten pool are also discussed.
