For the defect examined by non-destructive testing during in-service inspection, it shall be subject to a set of operations known as indication processing, which aim to identify and analyze a deviation situation, confirm whether or not this is a genuine defect and select the best processing solution. This paper is intended to illustrate an indication processing methodology that provides guidance on performing indication processing. Firstly, an indication processing method which covers indication identifying, deviation analysis, solution assessment, and solution implementation is specified. And then, some key technologies such as defect characterization, fatigue crack growth analysis applied in the indication processing methodology are descripted. Finally, some preliminary thinking is presented during introducing the indication processing methodology and some technical suggestions are also provided to perfect the methodology for providing better reference during application on PWRs in China. Actually, the study in this paper is preliminary and more research is needed to be done in the future.
