According to present plans, high level nuclear waste in Finland will be disposed of in bedrock at a depth of several hundred meters. The spent fuel containers will be placed in boreholes drilled in the floors of deposition tunnels with engineered clay buffer, which is made of bentonite blocks. The tunnels will be filled with a mixture of bentonite and crushed rock. Because of the weight of the container and the swelling pressure of bentonite, there is a possibility that the container will move significantly in the bentonite buffer. For calculation of such movement, a mathematical model of mechanical behavior of bentonite is needed. This report presents a thermodynamically consistent model for porous swelling material.
