This paper introduces a boron meter with improved accuracy compared with othercommercially available boron meters. Its design includes a new fitting function and amulti-detector. In pressurized water reactors (PWRs) in Korea, many boron meters havebeen used to continuously monitor boron concentration in reactor coolant. However, it isdifficult to use the boron meters in practice because the measurement uncertainty is high.
For this reason, there has been a strong demand for improvement in their accuracy. In thiswork, a boron meter evaluation model was developed, and two approaches were consideredto improve the boron meter accuracy: the first approach uses a new fitting functionand the second approach uses a multi-detector. With the new fitting function, the boronconcentration error was decreased from 3.30 ppm to 0.73 ppm. With the multi-detector, thecount signals were contaminated with noise such as field measurement data, and analyseswere repeated 1,000 times to obtain average and standard deviations of the boron concentrationerrors. Finally, using the new fitting formulation and multi-detector together,the average error was decreased from 5.95 ppm to 1.83 ppm and its standard deviation wasdecreased from 0.64 ppm to 0.26 ppm. This result represents a great improvement of theboron meter accuracy.
