Abstract:
The safety control component designed for the Venus-Ⅱ ADS critical experimental assembly (Venus-Ⅱ) includes safety rods and regulation control rods, which is the most important component for the reactor safety operation. In this paper, the reactivity worth of the selected control component was measured by the inverse dynamic reactivity meter method and the results were compared with the theoretical calculation results. The results show that the relative deviation of the reactivity worth between the experimental measurement and the theoretical calculation results of the safety control component is 4.46%, which means both are in good agreement. The results of mechanical analysis and evaluation for safety rod system show that stuck rod will not occur and the reactor can realize fast shutdown. The mechanical performance of the safety rods system and regulation control rods system was tested and their stability, reliability and repeatability are proved through repeated experiments.
