As the modernization of the nuclear instrumentation system progresses, research reactors have adopteddigital wide-range neutron power measurement (DWRNPM) systems. These systems typically monitorthe neutron flux across a range of over 10 decades. Because neutron detectors only measure the localneutron flux at their position, the local neutron flux must be converted to total reactor power throughcalibration, which involves mapping the local neutron flux level to a reference reactor power. Conventionally, the neutron power range is divided into smaller subranges because the neutron detectorsignal characteristics and the reference reactor power estimation methods are different for eachsubrange. Therefore, many factors should be considered when preparing the calibration procedure forDWRNPM channels. The main purpose of this work is to serve as a reference for performing the calibrationof DWRNPM systems in research reactors. This work provides a comprehensive overview of the calibration of DWRNPM channels by describingthe configuration of the DWRNPM system and by summarizing the theories of operation and thereference power estimation methods with their associated calibration procedure. The calibration procedurewas actually performed during the commissioning of an open-pool type research reactor, and theresults and experience are documented herein.
