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.

摘要： PROBLEM TO BE SOLVED: To provide a method for inspecting the inside of a reactor container, by which an environmental state in the reactor container can be easily grasped even when an instrument system cannot be used due to occurrence of an emergency.SOLUTION: A cylindrical attachment is attached to a preparatory penetration formed so as to be penetrated into the reactor container and a living body shield surrounding the reactor container and blocked by a sealing plate on the outside of the living body shield (S1). A valve is attached to the attachment and a processor unit is attached to the valve (S2). An aperture is formed on the sealing plate by using a processor of the processor unit (S4). The processor unit is detached by opening the valve to a full opened state (S5), and an instrument unit is attached to the valve (S6). An instrument in the instrument unit is inserted into the reactor container through the valve, the attachment and the penetration. Consequently, information in the reactor container is obtained by the instrument.
