Document Type and Number:
WIPO Patent Application WO/2018/225292
Kind Code:
A1
Abstract:
This supporting force inspection device is for inspecting the supporting force of a vibration suppression member interposed between the curved parts of a plurality of heat transfer tubes in a steam generator. The supporting force inspection device comprises an acceleration sensor for detecting the vibration state of the curved parts, a sensor holding part that is for holding the acceleration sensor and is disposed inside the heat transfer tubes, and a vibration generation unit for generating vibration force for causing the heat transfer tubes to vibrate along the plane of the osculating circles of the curved parts. The vibration generation unit works together with the sensor holding part to vibrate the heat transfer tubes along the plane of the osculating circles.
