Summary: | The utility model 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, and recording a measured minimum value and a measured maximum value; a value needing to be corrected is obtained through calculation, finally, the correction tool is placed at the deformed position, a hand-operated oil pump continuously presses oil into an oil cylinder by shaking a handle of the correction tool in a reciprocating mode, and due to continuous increasing of oil pressure in the oil cylinder, a 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 stora |
