摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a steam generator and a heat transfer tube inserting tool capable of simplifying an inserting process of heat transfer tubes.
SOLUTION: In this manufacturing method of the steam generator, a plurality of tube supporting plates having tube holes are arranged, and the heat transfer tubes are successively inserted to the tube holes of the tube supporting plates. This method comprises a heat transfer tube pressing step for pressing the heat transfer tubes to a prescribed lead-in starting position and inserting the same to the tube supporting plates, and a heat transfer tube lead-in step for leading the heat transfer tubes in the inserting direction from the lead-in starting position, and inserting the heat transfer tubes to the tube supporting plates. Here, a first inserting tool and a second inserting tool engaged with each other are used in the heat transfer tube inserting process. The first inserting tool is mounted on an end portion at an insertion side of the heat transfer tube first in the heat transfer tube pressing step, and then the second inserting tool is engaged with the first inserting tool and led in to lead the heat transfer tubes to a prescribed lead-in completion position in the heat transfer tube lead-in step.
