Stripa Mine, Sweden

The nature of a BMT study is well demonstrated with BMT3 of the DECOVALEX I project. It was a problem associated with a near-field repository model, set up as a two-dimensional plane-strain problem in which a tunnel with a deposition hole was located in a fractured rock mass. The model is 50 X 50 m in size, and situated at 500 m below the ground level (Figure 1). The fracture network is a two-dimensional realization of 6,580 fractures from a realistic three-dimensional fracture network model of the Stripa Mine, Sweden (Figure 2). The problem is set up as a fully coupled THM near-field repository problem, with thermal effects caused by heat release from radioactive waste in the deposition hole (the heater). Heat output decreases... 

Su et al. 27) conducted a series of laboratory tests using dyed water supplied into two Afferent setup models (1) a transparent replica (about IS-cm wide by 30-cm long) of a natural, rough-walled rock fracture from the Stripa Mine, Sweden, for inlet conditions of constant pressure and flow rate, over a range of inclination angles, and (2) parallel glass plates with three types of apertures. In these experiments water was supplied fiirough file whole width of a fiacture model.
