Abstract
Any transportation of spent nuclear fuel is a complex multifactorial problem requiring the coordination of numerous technical means including specialized transport containers, fasteners, reloading devices, grippers, dampers, and special wagons. One of the ways to solve such problems is to test a prototype of the fuel package unit under conditions simulating an aviation accident (collision with a rigid barrier at a velocity of 90 m/s). Tests using the capabilities of a rocket track have been presented in this work. An aerodynamic flow around the section of a video recording unit has been calculated under the conditions of an aeroballistic experiment. The strength and natural frequencies of the recording instrument used in the aeroballistic experiment have been evaluated. The modal calculation of the recording instrument has been performed using the finite element method. Ten forms of free oscillations of the recording instrument have been obtained. It has been concluded that the instrument is performable. The calculations have allowed installing a high-speed camera on the stage of a rocket train to increase the information content in the experiment for obtaining frames of acceleration and separation of the fuel package unit. Photos of the acceleration and separation of the fuel packing kit from the rocket train taken by the aboard camera have been presented. The reported studies have made it possible to justify and apply high-speed shooting from the upper stage of the rocket train in the simulation of the aviation accident for testing transport packaging kits according to the IAEA standards.
