Abstract
The analysis results show that the safety systems of the 65Â MW IPWR design adequately remove the core decay heat without causing a core uncovery for all the break cases. However, for some of the relatively large sizes of the breaks, the upstream region of the shutdown cooling system (SCS) suction pipe is completely voided after the break and it is not refilled with safety injection water throughout the transient, which prevents a proper operation of the normal SCS. Based on the results of this analysis, the 65Â MW IPWR specific long term cooling (LTC) procedure, independent of a break size, is suggested instead of using the normal operation of the SCS.
