Abstract:

Background: Dropping impact resistance property is a key characteristic for the transportation safety of transport container filled with radioactive liquid waste. Therefore, it is necessary to carry out dropping impact analysis of the transport container with the appropriate method during research and develop process. Purpose: Dropping impact analysis with appropriate method for the transport container filled with radioactive liquid waste was carried out to verify its dropping impact resistance property. Methods: Based on smoothed particle hydrodynamics method coupling with finite element method, dropping impact analysis of travelling spent resin incepting device filled with radioactive liquid waste in three different ways was carried out with LS-DYNA code which was an explicit dynamic analysis software. Besides, a stress strength assessment method for the device structure based on RCC-M and other rules was proposed, and the stress strength assessment was also performed with the method. Results: The dynamic excitation, the pressure variety and the stress of the device during dropping impact process were obtained in the paper. Conclusion: Smoothed particle hydrodynamics method coupling with finite element method is suitable for solving the fluid-structure interaction question during dropping impact process for the device filled with radioactive liquid waste. Furthermore, the strength of the device satisfies the requirement in three different ways of dropping.
