The invention belongs to the technical field of spent fuel dry storage in a nuclear power station, and particularly relates to correction equipment for a sealed storage tank for spent fuel dry storage, which comprises the following steps of: checking a deformed part of the sealed storage tank through a numerical value displayed by a graduated scale of a measuring tool, recording a measured minimum value and a measured maximum value, and calculating to obtain a value needing to be corrected; and finally, the correction tool is placed at the deformed position, a handle of the correction tool is shaken in a reciprocating mode, the manual oil pump continuously presses oil into the oil cylinder, and due to continuous increasing of oil pressure in the oil cylinder, the piston is forced to be pushed forwards, and meanwhile the deformed position of the sealed storage tank is recovered. The problem that the inner cover plate and the outer cover plate cannot be matched due to deformation of the sealed storage tank body
