  1. RTD on Radwaste Disposal in Germany Site Specific RTD (BfS) Applied Basic RTD (BMWA) Characterisation of the Gorleben Site moratorium (max. 10 ys) • Works in URL‘s with respect to coupled processes (THM-C) • Development of measuring and monitoring techniques • Determination of safety related data on backfill and sealing • Development of a coherent geochemical data base for RN sorption and retention • Development / testing of tools and methodologies for IPA New site selection envisaged by BMU on the basis of AkEnd recommendations Euradwaste_04

  2. Isolation time about 1 mio years Hydraulic conductivity of isolating rocks less than 10-10 m/s Very slow GW-movement at repository level High retention capacity of rocks Good gas / temperature - compatibility Favourable rock-mechanic conditions Low tendency of water flow path formation Good predictability with respect to spatial extension and rock mass homogeneity AkEnd – Geological Criteria for Site Selection Euradwaste_04

  3. RTD on mudrock and bentonite buffer clay-based buffer and mudrocks sealing materials as host rocks buffer in near-field sealing plugs/dams in mudrocks in granite (Mt. Terri, Bure, saturation behaviour (Äspö, FLG) Tournemire) gas diffusion in rock salt in clay thermomechanical (Sonders- (HADES) reactions hausen) NEA - IGSC application of EU - project Clay Club results in PA BENIPA AMIGO Euradwaste_04
