Description

In mid-1979 cracking was discovered in one of the feedwater lines of an operating PWR system. This paper presents the results of the 3-D stress analysis performed to determine the contribution of thermally stratified flow conditions to the feedwater line cracking. Excessive fatigue damages are predicted at locations which correlate well with the observed cracks. Thus thermal stratification is a prime contributor to the observed feedwater line cracking. 6 refs
