Resumo
Nowadays safety and security of spent nuclear fuel (SNF) interim storage installations are very important, due
to a great concentration of fission products, actinides and activation products. In this kind of storage it’s
necessary to consider the physical security. Nuclear installations have become more vulnerable. New types of
accidents must be considered in the design of these installations, which in the early days were not considered
like: fissile material stolen, terrorists’ acts and war conflicts, and traditional accidents concerning the transport
of the spent fuel from the reactor to the storage location, earthquakes occurrence, airplanes crash, etc. Studies
related to airplane falling had showed that a collision of big commercials airplanes at velocity of 800km/h
against SNF storage and specially designed concrete casks, do not result in serious structural injury to the casks,
and not even radionuclides liberation to the environment. However, it was demonstrated that attacks with
modern military ammunitions, against metallic casks, are calamitous. The casks could not support a direct
impact of this ammo and the released radioactive materials can expose the workers and public as well the local
environment to harmful radiation. This paper deals about the main basic aspects of a dry SNF storage
installation, that must be physically well protected, getting barriers that difficult the access of unauthorized
persons or vehicles, as well as, must structurally resist to incidents or accidents caused by unauthorized
intrusion.
