Abstract
In pressurized water reactor systems, pressure boundary components are mechanical systems that exhibit significant differences in pressure between the inside and outside of their boundaries. Any cracks and faults in pressure boundary components should be diagnosed in advance, and pressure boundary integrity should be continuously monitored. Against this backdrop, many diagnostic techniques based on various physical phenomena have been developed. However, most of these technical developments have been conducted in testbed, rather than in a commercial environment, and therefore, they require feasibility checks for more practical conditions. In this study, the vibratory characteristics of different types of faults in secondary piping are analyzed to estimate the field applicability of the vibration-based prognosis technology currently under development. The analysis results show that this technology is advantageous in diagnosing every type of fault in a commercial reactor environment.
