| The work aims to summarize the fuel transport cask drop analysis process, design the reasonable gesture analysis scheme, and make sure that the design of fuel transport cask can meet the requirements of GB 11806 rules for drop test through analysis. The method of dynamic FEA was used to analyze the drop of multi-position and multi-mode new fuel transport cask, and the analysis results were verified based on the test results. The analysis and test experience were summarized into the complete analysis process. Through the analysis, the worst drop gesture of the new fuel transport cask under normal transport conditions was 9° small angle drop, and the maximum deformation of cask shell under the condition was 49 mm. The worst drop gesture under accident transport conditions was forward vertical drop and the biggest impact force of fuel assemblies was 1.78 MN. In combination with the analysis and test results, the most unfavorable drop gesture analysis process and key technical points of the cask were summarized. Combined with the analysis and test results, the most unfavorable drop gesture of the new fuel transport cask is obtained, and the general analysis flow of the fuel transport cask drop is summarized. |
