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...

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.

ambient temperature temper bead welding BWR PWR repair SCC underwater laser beam welding
It is known that stress corrosion cracking (SCC) might occur at the weld of a reactor pressure vessel or core internals. Underwater laser beam clad welding for mitigation of SCC has been already established and the guideline “Underwater laser beam clad welding” was published. Moreover, the guideline “Seal welding” was also published as a repair method for SCC. In addition to these guidelines, the guideline “Underwater laser beam repair welding” was newly published in November, 2012 for the repair weldi...
