IRSN activities in physical protection in support of the IAEA: The insider threats approach

The objective of this paper is to present an approach to deal with internal threats which allows: (1) to identify specific potential internal threat for nuclear facility or transport based on the Design Basis Threat, (2) to specify the list of potential theft and sabotage targets, (3) how to protect these targets, (4) and how to evaluate the protection level of these targets to avoid unacceptable consequences in full compliance with IAEA standards and recommendations. The implementation of this approach leads to identify, if need be, ways of improvement or strengthening of the protection against the internal threat and to take adequate decisions of implementation of corrective measures
