Safety analysis on SMART anticipated transient without scram

With TASS/SMR code, safety analyses have been performed on the ATWS(anticipated transient without scram), which is possible to occur in SMART, to identify whether or not SMART satisfies acceptable criteria in ATWS condition. Initiating events considered in safety analyses are loss of feedwater flow, single control rod assembly withdrawal and control rod assembly bank withdrawal. 100% rated core power of beginning of core, middle of core and end of core are established as initial condition. According to analyses results, primary pressure resulted from control rod assembly bank withdrawal event is higher than those resulted from other 2 initiating events. However, there seems to be pressure margin in comparison with pressure criteria on the ATWS, 22.06 MPa
