摘要： PROBLEM TO BE SOLVED: To improve reliability in the measurement of the center of an in-pile structure in a nuclear power plant.
SOLUTION: In a method for measuring the center of an in-pile structure in a core to measure an installed center of the in-pile structure as an inspection or replacement of the in-pile structure in the nuclear power plant, a target is mounted on a reference in-pile structure for the measurement of the center, a plumb bob center measurement device is mounted on the in-pile structure where its center should be measured, and the work to move the plumb bob center measurement device from the initial position of a plumb end to the center position of the target and to align it is verified by an underwater camera to measure the center of the in-pile structure by the travel of an XY table hanging a plumb bob wire of the device. This improves the reliability in the measurement of the center.
