Abstract
In the frame of the FEBEX Project, an almost full-scale thermo-hydro-mechanical mock-up test was designed to improve the knowledge of the coupled THM processes in the Engineering Barrier System of the Spanish reference concept for the Deep Geological Disposal in Granite. The test runs under controlled boundary conditions.
More than 500 sensors measure the most important thermo-hydro-mechanical variables within the bentonite barrier; meanwhile, data acquisition and control systems manage, supervise, record and store the data generated. The sensors were chosen to withstand mechanical stress, high temperature, humidity and salinity coming from environment.
After more than eight and a half years, the test has become a source of valuable data, both in number of involved processes and duration of the experiment, including some qualitative conclusions, that indicates major implications of the thermal aspects in the transport processes.
