Abstract

The problem of radioactive contaminant transport in fractured porous me- dia has attracted considerable amount of attention, since it is an important issue in the performance assessment modeling of a geological repository for high level radioactive waste (HLW). An exact analytical solution is devel- oped for the problem of transient transport in discrete parallel fractures situated in a porous rock matrix. The solution takes into account advective transport in the fractures, molecular diffusion and mechanical dispersion along the fracture axes, molecular diffusion from the fracture to the porous matrix, absorption onto the face of matrix, absorption within the matrix, and
