4 - General architecture of the repository in a granite medium4.1.2.2 Building for receiving B and C waste and for preparing disposal packagesThe building for receiving the B and C waste and for preparing disposal packages has three schematicsections:- a zone for unloading the primary waste transport transfer casks,- a zone for manufacturing and storing the disposal packages,- a zone for transferring the disposal packages to the transfer shaft.Figure 4.1.2Schematic organisation of the B and C waste buildingThe transport transfer cask unloading zone is fitted with a travelling crane and shielded cells. Theprimary packages are extracted from the transfer casks and placed in buffer storage before beingretrieved and placed in disposal packages.The zone for manufacturing and storing the disposal packages consists of several manufacturing lines.Each line is made up of a succession of shielded cells. Two manufacturing lines are considered for Bwaste disposal packages and one line for the C waste disposal packages.The disposal packages are routed from the end of the line to the cask loading station. The casks arethen conveyed into the shaft building for transfer to the underground installations.All types of activities planned for this building are already implemented in similar industrial nuclearfacilities.4.1.2.3 Surface building for spent fuel reception and containerisationShould spent fuel disposal be considered (UOX and MOX), a specific additional facility will be builtto receive and condition it before transfer to the underground installations. This facility could behosted in extension linked to the previous building.Dossier 2005 Granite - ARCHITECTURE AND MANAGEMENT OF A GEOLOGICAL REPOSITORY54/228
