Summary
Thermal stresses in piping produce through-wall stress gradients that may influence crack growth in the pipe wall. In heavy water reactors (HWRs), the pressure-induced stress in piping is small due to the low pressure values. For major HWR plant transients, the thermal stresses (both wall profile and bending due to axial thermal growth) provide approximately 80% of the nominal pipe stress. Cases of local thermal stratification can provide a significant increase in the pipe stresses and the number of stress cycles applied to the piping. One focus in this paper will be to assess the impact of thermal stresses, in general, and thermal stratification, in particular, on the growth of flaws in a pipe due to fatigue loadings. The study will evaluate both the primary loop piping and the pressurizer surgeline piping. Evaluations of fatigue crack growth will be developed for both base material and weldments. The crack growth analysis for 60-year operation of a HWR plant will be reviewed. This analysis will be provided for the primary loop piping and the pressurizer surgeline piping and will establish the worst-case flaw size predicted from fatigue analysis by end of life.
