..., it is important to check the soundness of jet pump beam with BB-1, BB-2 and BB-3. In US, jet pump beam is inspected by Ultrasonic Testing (UT). However, there is some difficulty to perform UT because jet pump beams have some complicated shapes and are installed where it is not easily accessible. Since it causes...
