Abstract

Various analysis codes have been used for the 9m drop impact analysis of nuclear fuel casks, and analysis results are usually compared with the experimental results of scale model casks. Due to the complexity of mechanical behaviors, the results depend on how users apply the codes and it can cause severe errors during analysis. In the present study, ABAQUS/Explicit and LS-DYNA3D are implemented; we have investigated the analyzing technique for the drop impact test of the cask and found several vulnerable cases to errors. The analyzed results were compared with each others. Conclusively, we have suggested a reliable and relatively simple analysis technique for the drop test of nuclear fuel casks.
