A validation activity on version V1.3 of the CATHARE 2 code is being performed by ENEA. This activity aims to evaluate the code capability to predict the physical phenomena related to innovative safety systems in advanced water reactor. In the frame of this validation activity, a study has concerned the post-test analysis of experiments on the Automatic Depressurization System (ADS) of the AP600 reactor. The experiments had been carried out in the VAPORE facility at the ENEA Research Center of Casaccia (Rome, Italy). The ADS integral tests were especially suitable to verify the physical models of the code for critical flow and water entrainment on blowdown scenarios in typical PWR conditions. In order to meet this objective, a nodalization of the facility has been developed and has been applied for the interpretation of two different blowdown tests, characterized by different initial and boundary conditions. Although experimental results are proprietary, comparisons between calculated and measured parameters are shown in a normalized form.
