Thermal Stratification Effects on Surge Line Fatigue Life Based on Finite Element Analysis

Abstract:

Stress of pressurizer surge line due to stratification is calculated with the help of finite analysis software, using both simplified temperature distribution and the temperature fields of CFD simulation result. Stress and displacement of pressurizer surge line are achieved. Evaluation of the fatigue life reduction due to stratification is done by using modified fatigue design curve and referring to environmental fatigue factor. The conclusions here indicate that it can’t be neglected that stratification reduces the fatigue life of pressurizer surge line.
