    Pipe wall thinning is a significant issue affecting the structural integrity of plant pipe systems. Although many studies have been conducted to detect defects caused by pipe wall thinning, numerous challenges have hindered their performance. In this study, the changes in pipe vibration due to wall thinning were observed to monitor defects in pipe systems. A vibration experiment was conducted to analyze the dynamic behavior of a wall-thinned pipe in the secondary coolant system of a research reactor(HANARO). Based on these results, analysis models with varying wall thicknesses were developed, and the vibration characteristics corresponding to different thickness levels were analyzed.
