Radioactive waste disposal in granite. [Stripa mine]
The principal geotechnical problems in selecting a repository site for radioactive waste disposal in granite are to evaluate the suitability of the rock mass in terms of: (1) fracture characteristics, (2) thermomechanical effects, and (3) fracture hydrology. Underground experiments in a mine in Sweden have provided an opportunity to study these problems. The research has demonstrated the importance of hydrogeology and the need to improve predictions of the thermomechanical behavior of fractured rocks. To characterize a site, measurements made from the surface must be supplemented by extensive subsurface experiments. Much effort is needed to generate the technology required for the development of waste repositories

Laboratory investigations on the hydraulic and thermomechanical properties of fractured crystalline rocks
The laws of fluid flow in fractures, the dependence of fracture conductivity on the size of the sample tested, and the thermomechanical properties of both intact and discontinuous samples in crystalline rocks were discussed. (DC
