The concept of physical protection of nuclear facilities in Sweden

This paper will discuss the physical protection philosophy used to protect nuclear facilities in Sweden. It will also discuss the systematic approach used to develop the protection system starting from the development of a design basis threat. Furthermore it will in more detail discuss the pillars, all equally important, on which the protection is built i.e. multiple protective barriers, access control, system engineering and response forces. Finally the process to revise the present physical protection regulations will be described. (orig.)
