This paper presents a 3D FEM model for simulating the coupled THM behaviour of the buffer and buffer-rock interface behaviour of the Canister Retrieval Test conducted at the Äspö Hard Rock Laboratory, Sweden. The effect of the interface between the canister and buffer was also included. New numerical techniques were developed for more efficient FEM formulation and equation solution, and for modeling saturated or partially saturated water flow, gas flow and heat transfer in buffer and interfaces. The numerical results compare well with the measured data, and the reasonably good agreement between simulated and measured results indicates that the coupled THM processes of buffer material can be accurately predicted by the newly developed THM model and computer code.
