Storage in silos
Graphite 'sleeves' used to surround the fuel elements in the old type of French reactor, the gas-cooled, graphite-moderated reactor (GCR). The reactors of this type were decommissioned some years ago. The sleeves are stored (right) in a silo and a bunker. You can see (left) one of these silos, silo 115, containing 3 three 400 m3 ventilated steel tanks where production from 1966 to 1974 is stored (Source ANDRA Catalogue)
