PURPOSE:To improve reliability and response speed of a reactor power monitor by reducing the number of devices existing in the transmission path for commonly held detector outputs. CONSTITUTION:As for the detector output of a commonly used detector 1b, before it reaches a digital operator 35 by way of an analog-digital converter 34 of a device 31 on the transmission side, it is separated with a signal separation output part 33 placed behind a detector signal input part 32 of the device 31 on the transmission side and is supplied to the input of the analog-digital converter 34 in the device 32 on the reception side. Therefore, only a signal separation output part 33 must be added to the detector output path for the commonly held neutron detector 1b compared with the detectors 1a and 1b which are not commonly held and so the number of devices existing in the transmission path for the commonly held detector output can be drastically reduced compared with the case using data transmission.
