Maintenance support method and maintenance support device

Abstract

To provide a maintenance support method capable of properly supporting maintenance activities of a nuclear power plant.SOLUTION: In a maintenance support method of a maintenance support device 100 that supports a maintenance plan of a maintenance target system of a nuclear power plant, the nuclear power plant includes a system in which a first system and a second system interconnected with the first system are connected by a pipe. A plurality of input sensors are installed on an inlet side of the system or an inlet side of a device included in the system in each of the first system and the second system, and a plurality of output sensors are installed on an outlet side of the system or an outlet side of the device included in the system. A processing section 10 of the maintenance support device 100 selects a measuring object of the input sensor and the output sensor in estimating or determining a maintenance period, and estimates or determines the maintenance period of the first system and the second system on the basis of the selected measuring object.SELECTED DRAWING: Figure 1
