Simulators of this type are used for training and maintaining competence to ensure the safe and reliable operation of nuclear power plants throughout the world. In this study the response of the modernized Krško nuclear power plant (NPP) to a total-loss-of-feedwater accident, leading to the total loss of the secondary heat sink, was calculated. Based on these results, the validation of the full-scope simulator was performed. The verified plant-specific RELAP5/MOD2 input model of the Krško NPP, adapted for the 2000 MWt power (cycle 17), including the model for replacement steam generators, was used. Core heatup occurred in the analyzed case. Core degradation and melting are outside the scope of the RELAP5/MOD2 best-estimate code simulation, but it can predict all the events up to the moment when the core cladding temperature starts to approach the melting point. The comparison of the Krško full-scope simulator (KFSS) data with the calculated reference data shows good agreement and indicates that the simulator-validation testing for this kind of accident was successful.
