<P>PROBLEM TO BE SOLVED: To insert oscillation stopper members into predetermined positions between heat-transfer tubes. <P>SOLUTION: This method for manufacturing a steam generator with the oscillation stopper members 14 disposed between the heat-transfer tubes 5 includes: a step of layering double heat-transfer tube layers 5A horizontally arranged; and a step of inserting the oscillation stopper members 14 between the heat-transfer tube layers 5A. The steps are performed alternately from a lower side to an upper side. With the method for manufacturing the steam generator, since only one heat-transfer tube layer 5A exists above each oscillation stopper member 14, the position of the front end (bend portion) of each oscillation stopper member 14 can be visually confirmed from above. As a result, the oscillation stopper members 14 can be inserted into the predetermined positions between the heat-transfer tubes 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
