概要
2002, Stress Corrosion Cracking (SCC) came to be detected in the low carbon stainless steel PLR ; of BWR plants. These SCC were detected and evaluated by the Procedure for adding creeping wave ar wave of angle of 45° based on ultrasonic examination guidelines in In-service inspection (JEAG . However, it worke d on the improvement of ultrasonic examination technology for PLR Piping in BWR Owners Group (JBOG), because the mistake of the evaluation was caused as a rare case. In this it introduces the improvement of ultrasonic testing technology and evaluation.ords:ultrasonic examination, low carbon stainless steel, S tress Corrosion CrackingAfter 2002, Stress Corrosion Cracking (SCC) came to be detected in the low carbon stainless steel PLR Piping of BWR plants. These SCC were detected and evaluated by the Procedure for adding creeping wave to shear wave of angle of 45° based on ultrasonic examination guidelines in In-ser vice inspection (JEAG 4207). However, it worked on the improvement of ultrasonic examination technology for PLR Piping in Japan BWR Owners Group (JBOG), because the mistake of the evaluation was caused as a rare case. In this study, it introduces the improvement of ultrasonic testing technology and evaluation.
