Description

In PWR fuel assemblies(FAs), spacer grids(SGs) are very important structural components for laterally and vertically supporting the nuclear fuel rods(FRs). Based on the design experiences and by scrutinizing the design features of foreign advanced nuclear fuels and foreign patents of SGs, KAERI has devised 16 kinds of SG shapes and has been applying for domestic and foreign patents since 1997. To date, KAERI has obtained US, Japan, China, and Republic of Korea (ROK) patents for 15 kinds of SG shapes from them and the other is under review for patent-rights in USA, EC, China, and ROK. We carried out mechanical/structural performance tests on two KAERI devised SG shapes, which are assumed to be the most effective candidates for the SG of the next generation nuclear FA in ROK, and also on two commercial SGs for the sake of a comparison
