A reactor power output measurement device measuring a neutron flux with a traversing incore prove (TIP) traversing in a vertical direction in an in core of a reactor, and calibrating a detection sensitivity of a local power range monitor based on a measured neutron flux distribution in the axial direction inside the reactor, which is provided with an integrated control device 9 for transmitting control data to all of TIP drive control devices 13a through 13e and performing control/monitor of all of detector drive systems 17a through 17e, an integrated unit operation/monitor device 10 for operating/monitoring the integrated control device 9, and a TIP integrated controller 8 comprising an integrated unit input/output device 11 for inputting detection signals obtained from TIP detectors 18a through 18e to the integrated control device 9 via the integrated unit input/output device 11, and which switches to the integrated unit operation/monitor device 10 when the drive unit operation/monitor devices 15a through 15e suffer from failure.
