Influence of a Backfilling Material on Borosilicate Glass Leaching

  • F. Lanza (a1) and C. Ronsecco (a1)


When a canister containing a borosilicate glass incorporating highly radioactive waste is put into an underground repository, care must be taken in favouring the dispersion of the generated decay heat by conduction in the surrounding rock. For this purpose the space existing between the glass container and the repository walls is filled with a material having an acceptable thermal conductivity. If the backfilling material is highly compacted, it can form a zone of very low permeability reducing in this way the flow of water around the canister.
