摘要： A heat exchanger tube vibration suppression device and a steam generator are provided. The heat exchanger tube vibration suppression device includes: a plurality of sleeves (101) disposed in a heat exchanger tube (66) with a predetermined gap in relation to an inner surface of the heat exchanger tube (66) so as to extend in a longitudinal direction of the heat exchanger tube; and a connecting member (102) that connects the plurality of sleeves (101) so as to be movable between a contracted position at which adjacent sleeves (101) overlap at least partially and an extended position at which the amount of overlap of the adjacent sleeves (101) is minimized. In this way, it is possible to suppress the vibration of the heat exchanger tube appropriately.

摘要： An upper hole 37A and a lower hole 37B are provided at two positions, namely, upper and lower portions, of a side surface of a guide tube 27, and a thimble tube 22 is pressed against an inner circumferential surface of the guide tube 27, by a differential pressure between coolant inside and outside the upper hole 37A and the lower hole 37B. It is preferable that an upper pressure adjustment hole and a lower pressure adjustment hole are provided at two positions, namely, upper and lower portions, of a side surface of an upper core support column 21, and a coolant flowing into the guide tube from an upper end of the guide tube flows out to the outside from inside the guide tube through a gap between the thimble tube and the upper hole, and also flows out to the outside from inside the upper core support column through the upper pressure adjustment hole, and a coolant flowing into the guide tube from a lower end of the guide tube flows out to the outside from inside the guide tube through a gap between the thimble tube and the lower hole, and also flows out to the outside from inside the upper core support column through the lower pressure adjustment hole.
