title = "NUMERICAL PREDICTION OF THE REACTOR PRESSURE VESSEL MELTING UNDER IVR-ERVC CONDITIONS",
abstract = "A numerical model for the prediction of the melting process of the reactor pressure vessel under severe accident conditions is presented in this paper. The model is based on the enthalpy-porosity approach with an extension for continuous liquid fraction function. The model is implemented in OpenFoam CFD code and it is validated against the melt test of gallium in a rectangular cavity. Subsequently, the model is applied for the simulation of the reactor pressure vessel melting process under the thermal load from the molten corium during the IVR-ERVC condition. The predicted remaining vessel thicknesses by the model in this study are compared with the previous predictions using the lumped parameter method (LPM). A gentle decrease in the wall thickness is predicted in the present study in contrast with the sharp decrease predicted by the LPM code. This model could serve as a complementary tool to MELCOR codes in which the wall ablation of the lower head by melting cannot be considered.",
