    This work was performed in the framework of workpackage WP6 of the TIMODAZ project. All of the experimental works performed in TIMODAZ contribute to a better understanding of the processes occurring within the clay around a disposal system for heat-emitting waste in clay during the thermal transient phase. The knowledge gained within the TIMODAZ project allows assessing the significance of the Thermal Damaged Zone (TDZ) in the safety case for disposal in clay host rocks and provides direct feedback to repository design teams. In this report, the results obtained within TIMODAZ and their relevance for Performance Assessment are documented. The emphasis lies on the behaviour of the Boom Clay, but other clays considered as host formations in Europe (OPA, COX) are addressed as well. Within the context of the Safety and Feasibility Case 1, currently foreseen to be published in 2013, this document is considered as important reference regarding the EDZ evolution.
