An experiment was performed for the OECD/NEA ROSA-2 Project with the large-scale test facility (LSTF),which simulated a steam generator tube rupture (SGTR) accident due to a double-ended guillotine breakof one of steam generator (SG) U-tubes with operator recovery actions in a pressurized water reactor. Therelief valve of broken SG opened three times after the start of intact SG secondary-side depressurizationas the recovery action. Multi-dimensional phenomena specific to the SGTR accident appeared such assignificant thermal stratification in a cold leg in broken loop especially during the operation of highpressureinjection (HPI) system. The RELAP5/MOD3.3 code overpredicted the broken SG secondarysidepressure after the start of the intact SG secondary-side depressurization, and failed to calculatethe cold leg fluid temperature in broken loop. The combination of the number of the ruptured SG tubesand the HPI system operation difference was found to significantly affect the primary and SG secondarysidepressures through sensitivity analyses with the RELAP5 code.
