PROBLEM TO BE SOLVED: To provide a repairing device for shroud in a reactor pressure vessel. SOLUTION: The repairing device contains an upper stabilizer assembly, a lower stabilizer assembly and a tie-rod constituted to extend between the upper and the lower stabilizer assemblies and combine to them. The upper stabilizer contains an upper stabilizing block and an upper stabilizing wedge freely slidably combined with the upper stabilizing block. The lower stabilizer assembly contains a lower stabilizing block and a lower stabilizing wedge freely slidably combined with the lower stabilizing block. The tie-rod is cut into a screw at each end. One end is screwed with a tie-rod opening in the lower stabilizing block. The other end is accepted by the upper stabilizing block and is fixed by a tie-rod nut.
