REACTOR OUTPUT MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To efficiently record and preserve the backup function of an operation/ monitoring device of TIP driver and measured data. SOLUTION: A reactor output measuring device measures neutron flux with a mobile in-core detector (TIP) moving up and down direction in the core of reactor and calibrates detection sensitivity of a local output range monitor based on the measured neutron flux distribution in the axial direction of the reactor. A TIP integral controller 8 consisting of an integral controller 9 for transmitting control data to all TIP drive controllers 13a to 13e and controlling/ monitoring all drivers 17a to 17e, an integral part operation/controller 10 for operating and controlling the integral controller 9 and an integral input and output device 11 for inputting detection signal obtained with TIP detectors 18a to 18e via the integral input and output device 11 are provided. In case of a failure in drive part operation/monitor 15a to 15e, it is switched to the integral part operation/controller IQ.
