Abstract

Abstract

To optimize the accuracy calibration method of Class 1E RTD channel in the nuclear power plant to meet the accuracy requirements of power plant instrument, this paper begins with the measurement principle of RTD and the common channel calibration methods in the nuclear power plant, elaborates the calibration and correction methods that may be used in the installation, replacement and operation test for Class 1E RTDs, puts forward a calibration correction method for RTD channels incorporating the accuracy of analog-to-digital (A/D) converters, and gives the application mode of cross-calibration data from RTDs in process system temperature platforms for RTD channel calibration. Through analysis, calculation and application verification, this RTD channel calibration accuracy correction method can effectively improve instrument channel accuracy and demonstrates strong practical value.
