A study of the thermal behaviour of engineered barriers, in model form at reduced scale and in an underground test facility
This report considers the thermal behaviour of an engineered barrier with the selected French clay Fo-Ca (natural calcic smectite) as its major constituent. After installation this barrier was subjected simultaneously to the heat flux dissipated by the container and to a possible rehydration by contact with the host medium. The report consists of three parts. The first part is devoted to R & D studies concerning detectors suitable for the point measurement of the water concentration. The second part reports on experiments carried out in the laboratory concerning both the study of heat transfer during the so-called "dry" phase of the disposal (without any water being supplied externally) and the study of the phenomenon of fissurisation. The third part describes the in-situ experiment "BACCHUS", carried out in the underground test facility at Mol (Belgium).
