Abstract

The FEBEX in-situ test for geological disposal of high-level radioactive nuclear waste is used as a calculation model. By changing the initial permeability, the initial suction and the air entry value, variation of saturation, and suction under the coupled thermo-hydro-mechanical (THM) action are analyzed using a Code-Bright program after the closure of nuclear waste repository. By analyzing sensitivity of the three parameters on these traits, valuable reference is presented for the selection of buffer materials of the nuclear waste repository.

Key words： bentonite; coupled thermo-hydro-mechanical (THM); nuclear waste repository; numerical simulation
