Extract

The long term corrosion behaviour of the German HLW glass SM 58 LW 11, doped with 11 vt.% of inactive waste, was investigated in a simulated carnallite/rock salt environment. The experimental conditions were defined with respect to a hypothetical water entrance to a rock salt repository, i.e. temperatures up to 200°C and a pressure of 130 bar were applied; a specific brine from the quinary system MgCl2-MgSO4-NaCl-KCI-H2O (the so-called Q-brine [1] served as leachant. The effects of the corrosion were determined by weight loss measurements, by analyses of the leachates, and by the application of surface analytical techniques.
