VIBRATION SUPPRESSION MEMBER, VIBRATION SUPPRESSION MEMBER ARRANGEMENT METHOD AND STEAM GENERATOR

摘要

This arrangement method of a vibration suppression member (14) is for placing, in a gap between adjacent heat exchanger tubes, a vibration suppression member (14) provided with a cylindrical tube (31) and an inlet (32) which is provided in the cylindrical tube (31) and is for expanding cylindrical tube (31) by allowing a fluid to flow into the cylindrical tube (31), and involves a placing step for placing, in the gap, the cylindrical tube (31) of the vibration suppression member (14) before the fluid enters, an expansion step for expanding the cylindrical tube (31) by allowing the fluid to flow through the inlet (32) into the cylindrical tube (31), and a sealing step for sealing the inlet (32) in a state in which the cylindrical tube (31) has been expanded.
