- W2186088512 abstract "In context with the closure of the Morsleben repository (ERAM) the potential migration of brine and gas passing salt-concrete seals has to be evaluated. According to present knowledge the contact zone between the sealing body and the surrounding rock is an important migration path and thus is decisive for the permeability of the seal. In order to show that the hydraulic conductivity of the seal is sufficiently small, the permeability of the contact zone has to be quantified. Respectively, it has to be shown that no defects exist in the contact zone leading to an intolerable degree of permeability of the seal, i.e. exceeding a permeability of 10 -18 m 2 on average. According to technical regulations in Germany investigations on comparable structures are required to assess the tightness of contact zones. For this purpose a 10-year-old salt-concrete seal in the Asse mine in Lower Saxony has been investigated, whose structure is comparable to the seals planned for the ERAM. This seal had been built within the framework of an abandoned research project. A detailed investigation concept comprising in-situ measurements and laboratory tests was developed and a method has been established to transfer the boundary conditions of the Asse mine to the ERAM, where the seals will be constructed. In-situ measurement results from the Asse seal show permeabilities in the range between 10 -20 m 2 < k < 10 -24 m 2 at the contact zones to the walls and the floor, which indicates that the required permeability of k ≤ 10 –18 m 2 is achieved. At the roof, however, higher permeabilities in the range between 10 -12 m 2 to 10 -19 m 2 were measured indicating a strong heterogeneity of the contact zone to the roof. The results of ultrasonic measurements underlined the heterogeneity of the roof area, which shows defects and faults, whereas no heterogeneities were detected at the walls and only very few, isolated ones in the floor. Altogether, the results show that the required tightness will be achieved by constructing comparable seals in the ERAM, although the quality of the contact zone to the roof has to be improved." @default.
