Abstract: After many years in high pressure systems and technology, pipe breaks may occur. The occurrence of this event and analysis of it in a PWR reactor is too important, absolutely in highest grade of danger in double ended guillotine type of break. In this paper, containment volume has changed then variation of pressure and temperature of containment with time has been analysed. This simulation is done with a hand-made computer code. At last, the results of simulation are compared with plant reports.

Keywords: AP1000 reactor; containment; LOCA; two phases; heat transfer; change of volume.
