|Surface disposal of low activity waste|
Radioactive waste with a low level of activity can already be stored in surface disposal facilities. The photograph shows the storage of metallic casks containing waste with low an intermediate activity and short live in one such specialized site, the Centre de l’Aube in France. The metallic casks are put in a cell, then the interstices between the casks are filled with grits. Once filled, the ccll is topped by a concrete slab, then covered by a impermeable polyurethan layer to insure waterproofness.
