Array Probe Eddy Current Testing Surface Inspection Technique
Abstract An eddy current testing (ECT) system has been developed for inspecting weld surfaces of components in the reactor pressure vessel of nuclear plants. The system can be applied to curved surfaces with an ECT array probe, it can discriminat e flaws from other signal factors by using a combination of arrayed coils signal-phase. The system is applied to a mock-up of core internal components and the signal discrimination using the signal-phase clearly separated flaw and noise signals....

immersion methods in-vessel inspection phased array surface cracking Ultrasonic testing
Visual testing with underwater camera is performed for the inspection of structures in RPV. It has the case to be difficult to identify whether the indication is the crack or the imitated shape like scratch. In this case, the judgment needs much time. In this issue, the distinction method by surface ultrasonic wave emitted on the structure have been developed. This method could perform the in-situ judgment between the crack and the imitated shape by ultrasonic imaging technique with array probe....
