During operation of nuclear power plant, boron concentration of the primary system has to be monitored for timely finding the boron dilution accident and ensuring the reactor safety. To ensure the accuracy of the monitoring results, it is necessary to calibrate the boron concentration monitoring system regularly. This research aims to propose an effective method for the calibration of boron concentration monitoring system. A new automatic calibration method, which is studied on automatic acquisition of control parameters and calibration coefficients, is designed for improving the efficiency. The automatic acquisition method of control parameters is about automatically adjusting high voltages and screening thresholds by using the remote digital regulation technology. The automatic acquisition method of calibration coefficients is about automatically recording neutron counting rates by using the statistical fluctuation method. The results show that the plateau curve and threshold curve can be drawn automatically in the process of control parameter acquisition, the calibration coefficients can be calculated automatically in the process of calibration experiment, and the maximum error of experiment results meets the technical requirements of boron meter. This calibration method is suitable for the calibration of boron concentration monitoring systems, and meets the accuracy and efficiency requirements for periodic calibration.
