After Fukushima-Daiichi accident, nuclear power plants are highly requested to enhance safety against severe accident. It is important to prevent fatigue failure for operating nuclear power plants, especially pressure boundary of compon ts to ensure safety. This paper studies the failure database of nuclear power plant in Japan (NUCIA) and extracts the events caused by fatigue failure. Fatigue failure can be classified according to fatigue mechanism such as mechanical vibration, fluid vibration, high-cycl...
