Fig. 9. Fracture liquid flux vectors for flux multiplication factor 10 and reference thermal load at different times after emplacement. Solid lines show downward fluxes along a vertical line above the drift crown for a simulation with homogeneous fracture properties (drift crown is at z = 2.75 m). In comparison, the scattered symbols show results from a heterogeneous simulation at 100 yr, giving the flux magnitude in all grid elements above z = 0 m as a function of radial distance from the center of the drift (the drift wall is at r = 2.75 m).
