This report presents the conclusions of the International Review Team established by the NEA Secretariat at the request of the French government to perform a peer review of the Dossier 2001 Argile. The latter was produced by the French National Agency for Radioactive Waste Management (Andra) to describe the research, development and demonstration activities in the French programme on the disposal of high-level and long-lived radioactive waste in a deep geological repository excavated within an argillaceous formation.
