Available in abstract form only. Full text of publication follows: The PRACLAY Demonstration and Confirmation Experiments are a contribution to the Belgian Research, Development and Demonstration program, managed by ONDRAF/NIRAS (the National Agency for Radioactive Waste and Enriched Fissile Materials), to assess the safety and feasibility of geological disposal of HLW (High Level and Long Lived Radioactive Waste) in Boom Clay. The in situ part of the program focuses on the confirmation of the THM(C) behaviour of the host rock in the vicinity of the disposal facility. Most of the issues investigated in the PRACLAY In Situ program is therefore generic for all repository design for HLW (respecting the temperature criteria: T{sub max} around the overpack <100 deg. C). The large scale Heater Experiment is the core experiment of this program. It aims mainly to study the large scale THM(C) response of the Boom Clay to the excavation of a disposal gallery and to a large scale thermal load. The interactions between the Boom Clay and the lining are also investigated. The Heater Experiment is break down in three tests: the Gallery and Crossing Test, the Heater Test and the Seal Test. The Heater Experiment will reproduce, in a conservative way, the most penalising conditions in the Boom Clay that could occur in a real repository. The paper provides a discussion on the choices made for the design of this experiment and details the progress of the project. (authors)
