4 - General architecture of the repository in a granite mediumFigure 4.1.3Schematic organisation of a spent fuel building4.1.3 Industrial and administrative zoneThe industrial zone occupies an area of 30-40 ha. It is organised around the construction shaft.The main component buildings are:- the construction shaft operations buildings;- construction material (engineered barrier, concrete, backfill, etc.) preparation shops;- an explosive warehouse;- equipment maintenance and repair shops (electrical, hydraulic, mechanical, electromechanical,boiler-making, cabling, etc.);- service buildings (warehouses, stores, core library, concrete laboratory, etc.).This industrial zone is gradually built up as dictated by the underground works requirements. Thus forinstance, until the decision to close the repository is made, there is no need to build installations toincrease backfill material production capacities.The surface installations for site personnel management and administration are grouped around thepersonnel transfer shaft. These are basically office buildings, a central emergency building and a"living" space for the personnel working on the site (cloakrooms, showers, canteens, etc.)..4.1.4 Broken rock storage dumpThe excavation site broken muck is stored in an area, designated by the mining term "dump",constructed near the construction zone. While trying to recycle a maximum amount of the brokenmuck as repository backfill, a third to a half of the extracted volume could remain on the surface if noother recycling solution is found.Dossier 2005 Granite - ARCHITECTURE AND MANAGEMENT OF A GEOLOGICAL REPOSITORY55/228
