Abstract: Among a lot of factors participating in the saturation progress of buffer material in geological disposal for high level radioactive nuclear waste, the initial head, permeability and saturation degree are the most keys. The author uses a 2 D FEM code for coupled thermohydromechanical phenomena to analyze the influence of the three factors mentioned above on the saturation progress of buffer material. From the results it is known that the bigger of the values of the initial head, permeability and saturation degree is, the faster of the saturation velocity is; and vice versa.

Key words: buffer material, saturation degree, influential factor, 2D finite element analysis
