8 – Surface installationsFigure 8.1.1General view of surface installations8.2 Nuclear zone8.2.1 Overall logic for the nuclear zoneThe "nuclear" activities zone within the surface installations is a specific industrial zone, withcontrolled access. It includes:- a traditional controlled zone (without specific risk linked to the nuclear activity), comprising thesupport installations (fire service building, equipment warehouses, etc.). The manufacture andprocurement of the components needed to produce the disposal packages must at least have awarehouse in which to store these components,- a "sensitive" zone, corresponding to nuclear facilities governed by special Nuclear Facilityregulations. This zone is fully protected by a physical fence and a second level of access control.It includes the unloading and temporary storage facilities for the transport transfer casks, thebuildings where the waste is received and the disposal packages are prepared, the package transfershaft to the underground installations and the air exhaust shaft.The functional features of the nuclear "sensitive" zone in terms of the type of waste to be handleddepends on the study scenario considered. It includes B and C waste-specific buildings. In the studyscenarios including the hypothesis of spent fuel disposal, a dedicated building would be added.DOSSIER 2005 ARGILE -ARCHITECTURE AND MANAGEMENT OF A GEOLOGICAL DISPOSAL SYSTEM323/495
