The purpose of this study was to evaluate potential crush loads on radioactive material packages in highway, rail, and marine accidents. The study concluded that if allowance is made for small gaps between packages, the deflections produced by inertial crush are comparable (within 20%) of those produced by impact under the same accident conditions. Therefore an additional qualification test is not needed to ensure that the level of protection against crush is comparable to the current level of protection against impact. The study also evaluated potential crush loads in extremely severe transportation accidents. In highway accidents, the most severe crush environment is produced when a truck carrying several small, soft packages strikes a rigid barrier and the inertia of the aft packages crushes the front package. In railroad accidents, severe crush environments are produced when a railcar on which the packages are carried strikes a barrier or when the packages are pinned between two railcars after a derailment. Analysis of ship collisions showed that for packages carried by a containerized cargo ship struck by another ship, the probability of producing significant crush loads is small because most collisions occur at low velocities during maneuvering. The study suggested various types of package tests which would simulate severe crush loads in each mode of transport.
