Abstract

The work aims to systematically verify the thermal performance of a certain spent fuel transport cask under normal and accident conditions, and evaluate its structural integrity under specific impact conditions, so as to provide a technical approach for thermal and impact resistance analysis of similar casks. The finite element numerical simulation method was applied to analyze and study the following operating conditions of the transport cask: (1) thermal analysis of the cask under normal and accident transport conditions; (2) research on the temperature distribution characteristics of spent fuel assemblies with different power ratios inside the cask; (3) 1-meter drop bar penetration test under normal operating conditions; and (4) 9-meter drop test and 1-meter puncture test under accident conditions. The numerical simulation results showed that the cask body and spent fuel assemblies had good thermal safety under normal and accident transportation conditions, and all components did not exceed the maximum temperature limit; Under various impact loads, the cask met the stress intensity requirements, ensuring the structural integrity of the cask at specific locations under corresponding impact conditions. All the above calculation results meet the relevant regulatory requirements, and this research result can provide a reference for the thermal and impact resistance performance analysis of spent fuel transport casks.
