Performance analysis on the operation of SMART main coolant pump 1 stop

With TASS/SMR code, performance analyses have been performed on the MCP 1 stop operation of SMART. According to the performance analysis considering 100% power level of BOC condition, delay time of measuring instruments, control logic for the event scenario and some assumptions, major system parameters, including system pressure, inlet temperature of primary steam generator, outlet steam of secondary steam generator and etc., were maintained within the allowable criteria. The coolant temperature of core node was also maintained quite below saturated condition. In addition, under MOC and EOC conditions, performance analyses on the MCP 1 stop operation have been performed. Under MOC and BOC conditions, the allowable criteria on major parameters were not violated, and the trends of the parameters were analyzed to be similar to those of BOC condition
