６の貼付位置を決めていた。The dimensions of the cell 11 forming the tank 9 are about 2 m × 15 m, and two to four hanging members for slinging are welded. This hanging metal fitting is eventually removed, but if the trace of the hanging metal fitting is repaired by welding, it is necessary to perform a radiological inspection on this as well. In this case, the distance from the vertical seam 12 and the horizontal seam 13 is measured. Position of the irradiation device 14 and the film 1
