PROBLEM TO BE SOLVED: To simultaneously perform extraction/insertion of control rods and taking out/loading of fuels, when a nuclear reactor is inspected. SOLUTION: The device and the system are provided with a fuel exchanging machine automatization interlock control means, a fuel exchanging machine automatization control means, a core state storage portion for storing states of fuel loading and states of insertion of control rods, a core state supervision means which checks the state of fuel loading of a cell on the basis of a state of fuel loading and a state of insertion of control rods, judges whether or not it is possible to perform fuel movement and extraction/insertion operation of control rods, and records an operation completion result in the core state storage portion, a fuel exchanging procedure storage portion which preserves procedures for fuel movement and procedures for extraction and insertion operation of control rods, and a fuel exchanging procedure progress supervision means which takes out grab and release co-ordinates of the fuel movement procedures successively from the fuel exchanging procedure storage portion, inputs control rod selection information from a control rod inserted state supervision means, reports the grab and release co-ordinates of the fuel movement procedures and the co-ordinates of a control rod to the core state supervision means, and directs fuel movement work if the grab and release co-ordinates of the fuel movement procedures do not correspond to the co-ordinates of fuels around the selected control rod.
