The design of the TUK-109T large-size container developed at the All-Russia Research Institute of Experimental Physics (VNIIEF) for transporting ampuls with bundles of spent fuel pins is described. The results of full-scale tests and three-dimensional simulation modeling for strength validation for mechanical actions occurring under normal operating conditions and during emergencies are presented. The computational validation of strength was performed in a three-dimensional formulation based on a finite-element model and a validated methodology of modeling dynamic deformation of structures, implemented in the highly parallelized LOGOS software. The validation of the methodology was performed by comparing numerical results with full-scale design tests. The computational prediction is shown to be highly accurate.
