Abstract

Abstract

Fatigue and strength analysis are carried out for the CRF pump shaft with correction flaws which are found during outage of Ling’ao Nuclear Power Plant. Moreover, the corrosion flaws are considered as initial cracks and stability of these cracks are evaluated. Life of the pump shaft is further confirmed. Through the aforementioned analysis procedure, structural safety of the pump shaft with flaws can be evaluated, which provides the technical support for on-site decision.
