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

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
