The purpose of the vortex detector of residual heat removal pump and the actions after the alarm presence are introduced.Meanwhile,the measures to avoid vortex presence at the suction of the pump are described. Combined with the triggering of the alarm when the plant meeting with the measures requested by design. The process of triggering the alarm is described and the reasons are analyzed detailedly,while the mechanization of vortex detector is introduced. At last,the probable influence and requested responds are analyzed, along with the settlements to avoid vortex when the pumps operate normally.
