Acoustic emission. Flaw relationship for in-service monitoring of nuclear pressure vessels

Conference ·
OSTI ID:6678765

Acoustic emission (AE) testing has the potential of being a valuable NDI method with capability for continuous monitoring, high sensitivity, and remote flaw location. Tests of the method were carried out on ASTM A533 Grade B, Class 1 steel. Crack growth AE signals could be recognized. An AE/fracture mechanics relation was developed for flaw interpretation. Two intermediate vessel tests at ORNL under the HSST program were analyzed. A simulated reactor vessel test and installation of an AE sensing system on a reactor are planned. (DLC)
