According to the requirements of China Experimental Fast Reactor (CEFR), a diffusion system hydrogen meter is designed to detect the water / steam leakage of steam generator. Based on the dynamic equation of diffusion hydrogen, the relationship between the sensitivity and response characteristics of diffusion hydrogen meter and its component parameters and thermal parameters was deduced. The influence of each component parameter on its performance was analyzed. In order to eliminate sodium The effect of temperature on the performance of diffusible hydrogen meters was maintained at a temperature of 500 ° C using a temperature-controlled method to reach the nickel tube of each hydrogen gauge in the steam generator. The sensitivity and response characteristics of a diffused hydrogen meter to be applied to predict the water / steam leakage of its steam generator by China Experimental Fast Reactor (CEFR) are given.
