Abstract

Abstract

This paper introduces the study on DRWM in China Nuclear Power Technology Research Institute（CNPRI）. Firstly, a code named sim ADRC is developed to repeat the method which adopted by DRWM module of ADRC. Then the DRWM correct coefficients calculation module is developed based on SCIENCE. The module is verified by the analog experiment based on sim ADRC and a set of history RPN current data of DRWM experiments. Result shows that the new developed module works well, with the maximum bank worth error only 5.7%, which is less than the acceptance criterion 10%.
