Abstract

Abstract

In order to establish the analysis method and process of thermal stratification and the impact of operating environment on the fatigue of pressurizer surge line (hereinafter referred to as “surge line”), the fatigue state of surge line is analyzed and predicted through numerical simulation, thermal stratification load analysis and environmental impact coefficient analysis and calculation. The research results show that due to the influence of thermal stratification and operating environment, the cumulative fatigue utilization factor (CUF) of the surge line at the end of its life is close to 1.0, so it is necessary to install an online fatigue monitoring system to monitor the fatigue of the surge line in real time to avoid sudden breakage.
