Description
A spacer grid is one of the structural core components of nuclear fuel assemblies for pressurized light water reactors. Since 1997, Korea Atomic Energy Research Institute (KAERI) has devised 16 kinds of spacer grid shapes and up to now acquired US, Japan, and Republic of Korea (ROK) patents for 15 kinds of spacer grid shapes from them. The mechanical and structural performance analyses and tests for two of the KAERI devised spacer grid shapes that are assumed to be the most effective candidates for the spacer grid of the next generation nuclear fuel assembly in ROK, were performed. Also tests for two commercial spacer grids were performed for the sake of a comparison. In this paper, the results are carefully compared and discussed. The comparisons included the spring characteristics, fuel rod vibration characteristics, fretting wear resistance, and the impact characteristics of the spacer grids. The comparison results have shown that the performances of the KAERI devised spacer grids are better or at least not worse than those of the commercial spacer grids. (authors)
