Exciter Coil Flux Guide High Sensitivity Outer Defect Remote Field Eddy Current Testing
In the remote field eddy current testing, we proposed the method of enhancing the magnetic flux density in the vicinity of an exciter coil by controlling the ma gnetic flux direction for increasing the sensitivity of detecting outer defects on a tube and used the flux guide made of a magnetic material for the method. T he optimum structural shape of the flux guide was designed by the magnetic field analysis. On the experiment with the application of the flux guide, the magneti c flux density increased by 5...

Bottom-mounted instrumentation BWR Eddy current testing PWR Stress corrosion cracking
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 scanning equipment based on the portable laser peening system. According to the experimental results that measured the sensitivity for the defects on the concave specimen and the relationship between the senso...

BWR Defect detecting capability Eddy current testing PWR Underwater laser beam welding
Abstract We clarified a defect detecting capability of eddy current testing (ECT) as a surface inspection technique for underwater laser beam welding. An underwater laser beam welding procedure includes groove caving as a preparation, laser beam welding in groove and welding surface grinding as a post treatment. Therefore groove and grinded welding surface inspections are required underwater. We curried out defect detection test s using three kinds of specimens simulated a groove, reactor vessel nozzle dis...
