(GRS 171) Gas Release and Migration in the Boom Clay of Mol within the Project „Corrosion of Active Glass in the Underground Conditions“ (CORALUS)

Norbert Jockwer, Klaus Wieczorek

The overall objective of the CORALUS project is to study the performance of both activeand inactive HLW glass specimens in direct contact with different types of backfillmaterials under conditions as representative as possible for those expected to prevailin a disposal site in the Boom clay formation (α- and γ-irradiation, temperature, pressure,backfill material, formation water,...). The experimental set-up represents a scenarioin which the vitrified waste comes into direct contact with the interacting backfillmaterial and/or the Boom clay, because of the occurrence of fissures in the wastecanisters and the metallic overpack.
