The Effect of a Free Drop Impact on the Bolted Joint of the Radioactive Transport Package

Abstract:

In this study the effect of a free drop impact on the bolted joint of the transport package of radioactive material was studied under various directions. A drop test of a type A or a type IP transport package of radioactive material should be conducted under normal transport conditions. After a drop test the radioactive content of the transport package should not be loss or dispersal. A bolt tension during a drop impact under various directions was measured using a force sensor. And the torque to loosen a bolt was measured after the tests. A bolt tension measured by the tests was compared with the result of a finite element analysis. The effect of the drop direction was examined. The vertical drop directions shows larger bolt tension than horizontal drop. For the torque to loosen a bolt, a horizontal drop condition shows larger value than a vertical drop direction.
