BEARING CAPACITY INSPECTION DEVICE AND BEARING CAPACITY INSPECTION METHOD

摘要

To accurately inspect bearing capacity in a direction along a surface where a circle of curvature of a bent part exists, from a vibration stop member interposed between bent parts of a plurality of heat transfer tubes in a steam generator.SOLUTION: A bearing capacity inspection device is configured to inspect bearing capacity of a vibration stop member interposed between bent parts of a plurality of heat transfer tubes in a steam generator. The bearing capacity inspection device comprises: an acceleration sensor configured to detect a vibration state of the bent part; a sensor holding part holding the acceleration sensor, wherein the sensor holding part is arranged in the heat transfer tube; and an exciting force generation part configured to generate exciting force for vibrating the heat transfer tube, along a surface where a circle of curvature of the bant part exists. The exciting force generation part is configured to cooperate with the sensor holding part, to vibrate the heat transfer tube along the surface where the circle of curvature exists.SELECTED DRAWING: Figure 4
