Abstract

Abstract

The design and improvement characteristics of CF series fuel assemblies with completely independent intellectual property rights in China are introduced in this paper. The performance parameters of CF series fuel assemblies such as rod drop time, rod drop velocity and rod drop impact force under different conditions are obtained through 1∶1 cold and hot out-of-core simulation tests, and the differences in rod drop performance between CF2 and CF3 fuel assemblies, as well as between CF2S and CF3S fuel assemblies are compared. The experiment results show that CF3 series fuel assemblies have a longer rod drop time and a lower rod drop impact force compared with CF2 series. The improvement of guide tube structure has a greater influence on rod drop buffer time. The experimental results validate the effectiveness of the design improvements and provide support for the practical reactor application and further development of CF series fuel assemblies.
