Maine Yankee steam generator tube sleeving thermal-hydraulic and safety analysis impacts
1996
This paper discusses the impact of the complete plugging and sleeving campaign at Maine Yankee on the thermal-hydraulic analysis. A discussion of the hydraulic resistance calculations associated with the plugging and sleeving is provided. Finally, the impact on the plant safety analyses is provided, considering the changes in the hydraulic resistance of the steam generator tubes and the associated impact on reactor coolant system flow rate including asymmetry, steam generator overall heat transfer capability (UA), LOCA, reactor coolant pump coastdown, and Reactor Protection System trip setpoints.
