IN TRANSIT STORAGE OF RADIOACTIVE MATERIAL UNDER NATIONAL CUSTOMS ADMINISTRATION

A model of an \"in transit storage of radioactive materials\" under National Customs Administration control< 1 > is described account the relevant Custom House Legislation and the Nuclear Regulatory Standardsc 2 > in force in Argentina. Evaluation of the physical protection systems a~plied to the above mentioned storage by means of a software named \"lntruBuster•>< > is also described. This software is routinely updated and is also used by the Nuclear Regulatory Authority to evaluate the adequacy of physical protection systems implemented at nuclear installations in the Country. The interaction with National and International related Organisations to minimise the probability of illicit trafficking of nuclear materials is another important aspect to be considered. This is particularly true in those cases in which the administration of these stores is privately operated. Finally, the paper describes the experience obtained in the implementation of the above mentioned software as well as prosecution and control activities by the Custom House and the Nuclear Regulatory Authority of Argentina.
