Safety verification for the ECCS driven by the electrically 4 trains during LBLOCA reflood phase using ATLAS

The overall experimental results revealed the typical thermal-hydraulic trends expected to occur during the reflood phase of a large-break LOCA scenario for the APR1400. Experiment with the injection of three SIPs showed a faster core quenching time and lower bypass ratio than that of the case in which two SIPs were injected. The RPV wall temperature distributions showed the similar trend in spite of the different SIP combinations.
