A model of heat structure wall surface film coverage and evaporation was developed based on 3 dimensional CFD containment code GASFLOW. The containment temperature and pressure response and the passive containment cooling system (PCS) performance of AP1000 during large break LOCA were analyzed by GASFLOW code coupled with film model. The calculation results were compared with the calculated results of other containment codes WGOTHIC, MELCOR, CONTAIN under the same accident scenario. The results show that the modified GASFLOW code coupled with film model is feasible to analyze the thermal-hydraulic behavior in PCS of PWR and the basic functions can meet the requirements for the calculation.
