  • In this paper,the severe accident induced by Station Blackout(SBO) of CPR1000 is simulated by SCDAP/RELAP5 code.The progression from the initiation of core uncovering and the full uncovering of the core to the core melt relocation into the lower head are analyzed.The heat transfer behavior of molten pool in the lower head is also discussed in this paper.The results achieved indicate that the damage location is at the 30°~40° side surface of the lower head(taking the bottom of PRV as 0°).
