[en] The project studies the transport properties of channels through discrete fracture network model (DFN). The DFN model consists of three sets of stochastic fractures of a typical Swedish fractured rock mass. The pathway analysis provides pathway characteristics. These characteristics are the CCDF (Complementary Cumulative Density Function) of V, 1/v, 1/(bv), τ and β. V is the magnitude of the flow velocity in the whole DFN model (Eulerian), v is the flow velocity along a path (Lagrangian), b is the half-aperture of the fracture, τ is the residence time of the particles and β is a Lagrangian parameter that defines the transport resistance. This project combines FracMan/FracWorks for fracture network generation with FracMan/MAFIC for flow and particle tracking and transport. The hydraulic transport modelling of flow pathways will be based on a base case DFN with variation cases. These variations will concern mainly the boundary conditions of the model, the geometry of the DFN, and the pathway calculation method. The method is based on stochastically generated fractures, each separate case is modelled by 20 realisations. The Base Case model is set-up to reflect the hydraulic behaviour of a typical Swedish fractured rock mass. The DFN model used was developed by Stigsson et al. to model the hydraulic behaviour of the prototype repository of the Aespoe HRL. The size of the model is in the 100m scale. The project provided the following results: Alternative streamline routing algorithm implemented in MAFIC provides results that are very similar to the Base Case Alternative fracture intensity P 32 set to 50% of the original fracture intensity produces results very similar to the Base Case. A high level of confidence in the fracture intensity P 32 from field data is therefore not required for transport calculations as long as the fracture intensity is sufficient. Alternative fracture intensity P 32 set to 10% of the original fracture intensity produces results that are different from the Base Case. A fracture intensity too low can greatly affect the connectivity of the DFN. The use of the DOE law and the cubic law as a relationship between the fracture aperture and the transmissivity presents significant but not large differences. The use of a linear relationship between the fracture aperture and the transmissivity was found difficult to calibrate and is inappropriate for the wide range of transmissivities used in the study. A correlation between the discharge at the upstream boundaries and the general characteristics of the pathways could not be observed. The CCDFs of the travel time of the particles show similar results for all cases. The results can still change by some orders of magnitude depending on the boundary conditions. The CCDFs of the retention factor are similar for all cases using the MAFIC transport solutions. The PAWorks solution (pipe network analysis) is rather different and presents lower retention factors within a smaller range. The CCDFs of the ratio 1/bv of the Lagrangian data are similar for all cases using the MAFIC transport solutions. The PAWorks solution is rather different and presents lower ratio 1/bv within a smaller range. The Eulerian CCDFs of 1/v and 1/bv show that all cases behave in a similar way except when the fracture intensity is low
