We confirmed the defect detection performance of the eddy current testing (ECT) system in order to inspect the bottom-Mounted instrumentation (BMI) nozzle in reactor pressure vessel. We developed the small size cross coil type ECT sensor that has the magnetic cores near the coils and the sensor driving unit based on the portable laser peening system. According to the experimental result that measured the relationship between the sensor inclined angle and defect detecting sensitivity on the convex surfa...

Development of Eddy Current Testing System for Bottom-Mounted Instrumentation Nozzle in Reactor Pressure Vessel

Recently, an application target of the phased array ultrasonic testing (PAUT) has been extended. However, it was known that PAUT was difficult to apply to components with complex and high damping materials such as cast austenitic stainless steel (CASS). The Authors have developed shape adaptive beam forming PAUT system for complicated shape parts and comprehensive PAUT conditions analysis system for CASS. Each PAUT systems based on full matrix capture (FMC) technique. In order to enhance an applicability of...
