Summary:The International Stripa Project (1980-1990) investigated the thermal, mechanical, thermomechanical, hydrogeological, geophysical and geochemical properties of granite at Stripa, central Sweden, to assess the conditions for the safe disposal of high-level radioactive waste. Investigations were carried out by subsurface drilling in the granitic part of a disused iron mine. The granite is highly radioactive with unusual water chemistry, extensive microfracturing and low permeability with isolated fractures of high permeability, but with typical granite mineralogy. Thin veins carry calcite, chlorite, sericite, epidote and quartz. The mine has perturbed groundwater flow to 3 km depth, and may have induced deep ground-waters to flow into the mine.
