Proposal for a steel cube container with improved impact resistant performance based on the drop test and numerical analyses

Abstract

The development of a large cube container for low-level radioactive waste is necessary in order to ensure the efficient disposal of radioactive waste. Because waste disposal facilities are required to undergo a safety assessment in case of severe accidents, such a disposal container needs to be tested for impact resistant performance. In this study, a pre-simulation for a cube container previously designed, was carried out in order to decide the test conditions. The drop test conducted, used a full-scale container at its corner edge orientation. During the test, the lid bolts broke and the lid fell out. Taking into consideration these results, as well as the numerical analyses, the study proposes a container structure with improved impact resistant performance.
