Abstract: There have been significant innovations in Pressure Vessels and Piping (PVP) technology over the last decade. In Europe and North America, inspection and evaluation methods using risk-based and performance-based ideas have ...

Abstract: The material of primary coolant pipe of nuclear power plants is cast austenitic stainless steel (CASS), which has a coarse crystal structure and its anisotropy causes low permeability of ultrasonic waves and low detectability. ...

Abstract: An inverse heat conduction analysis method for piping elbow was developed to estimate the temperature and stress distribution on the inner surface by measuring the outer surface temperature. In the paper, the accuracy for ...

Abstract: High temperature stratified flow sometimes caused thermal fatigue cracking in power plants. To prevent fatigue damage by stratified flow, it is important to know temperature distribution history in a pipe. In this study, ...

Abstract: With the long-term operation of nuclear power plants, evaluating the integrity of reactor pressure vessels (RPVs) against neutron irradiation has become increasingly important. In the context of pressurized thermal shock ...
