摘　　要：波动管作为核电站一回路压力边界的重要承压部件,在其寿命期内除了需要承受系统各类瞬态载荷,还要额外承受热分层载荷。为了得到波动管实际的热分层数据,设计了波动管温度监测系统,对波动管进行温度测量,掌握实际的波动管热分层情况,结合测量数据和设计瞬态,对某核电站波动管及其三通在热分层影响下的疲劳寿命进行了评估。为波动管热分层监测和寿命评估提供建议。As one of the important equipment insuring the integrity of primary loop pressure boundary, surge line suffers the thermal stratification loads besides varies transient loads during its life time. In order to obtain the actual thermal stratification data, a temperature monitoring system are designed. Based on the real thermal stratification data, bounding up design transients,the fatigue life of a specific surge line and its tee were evaluated including thermal stratification effects. Suggestions of surge line stratification moni- toring and life evaluation are provided.
