It is necessary to confirm the validity of crack detection by ultrasonic testing through a stainless steel weld in order to reduce a range impossible of detection by ultrasonic testing. Therefore, we performed ultrasonic testing used to specimen with various weld joint types for providing the basic data (probability and measurement accuracy) of ultrasonic testing methods to reflect on JEAC4207.As the result, ultrasonic testing used to longitudinal wave angle beam technique(including phased array techni...

Water environment improvement (ex. Hydrogen Water Chemistry (HWC)) is carried out for Stress Corrosion Cracking (SCC) mitigation in some of BWR plants. Japan Nuclear Technology Institute (JANTI) has the guideline on the inspection programs based on effectiveness of environmental SCC mitigation technique for BWR core internals. The guideline provides the crack growth rate (CGR) under HWC. Although CGR is defined by ECP (electroch emical corrosion potential), a dealing of evaluation of ECP and the HWC avail...
