Experimental setup for boron meter accuracy analysis in nuclear reactor environment

Abstract

This study introduces an experimental setup for test of boron meter with improved accuracy. A boron meter is used to measure the concentration of boric acid but its improvement has been required due to the low accuracy. Multi-detector boron meter by combination of low and high sensitivity detectors was designed to improve accuracy. Monte-Carlos simulation showed the theoretical enhancement of accuracy by using multi-detector. For enhancement of nuclear safety, an experimental setup based on the simulation was established to analyze the accuracy of new concept boron meter in the real reactor environment.
