PROBLEM TO BE SOLVED: To eliminate a scaffold, and to enhance safety and workability for stud bolt storing work. SOLUTION: A height of a storage rack 1 for a stud bolt of a reactor pressure vessel is made lower than a length of the stud bolt and made low to a height of the level substantially the same to a height of a flange part 11(FIG.5) of an upper lid 9 of the reactor pressure vessel. The efficiency for the storage work is enhanced since a length of an overturn preventive support is shortened thereby to allow installation onto a dry well 13. The stud bolt storage rack is made to be compact as the whole because attachments such as the scaffold and the support are eliminated compared with conventional structure. COPYRIGHT: (C)2004,JPO
