Abstract

Abstract

Static buckling load is an important concept for assessing the structural performance of the spacer grid. The finite element analysis（FEA） of static critical buckling load for 3×3 spacer grid has been investigated with analyzing the influence of grid structural characteristics. Results show that the fuel rod retaining state can be accurately simulated by the suitable setting of welding spot and contact. The fuel rod loading state, initial retaining force and friction have great effects on the results of this method.
