Mixed Primal–Dual Method for Nuclear Waste Disposal Far Field Simulation

A mixed finite volume method is applied in order to simulate a simplified Far Field model. We show how this method can be adapted to both the elliptic and the convection–diffusion equations describing the water flow and the variations of the concentration of the radioactive element respectively. For the water flow problem, we justify an a posteriori error estimator. Finally, we present some numerical results.
