The CIuster EDZ international conference and workshop on the 'Impact of the excavation disturbed or damaged zone (EDZ) on the performance of radioactive waste geological repositories' was jointly organised by the European Commission (EC) and ESV Euridice EIG, Belgium, in the framework of the EC Cluster Forum (CLub of Underground Storage, TEsting and Research facilities for radioactive waste disposal), in Luxembourg, from 3 to 5 November 2003. The Cluster EDZ conference had three main objectives: 1. to establish the present understanding of the nature and properties of EDZ; 2. to establish the consequences of the EDZ and propose remedial action for the different repository stages (from the design stage to the closure phase); 3. to assess the impact of the EDZ on the long-term performance of geological repositories. The present proceedings include the papers presented at, and the conclusions from, the Cluster EDZ conference and workshop as follows: 1. introductory keynote addresses on the relevance of the EDZ for post-closure safety of deep geological repositories, the conclusions of previous international workshops on the EDZ and the lessons learnt in each of the specific host-rock considered as potential formation to build a deep underground repository for radioactive waste (plastic and indurated clays, crystalIine rock and salt); 2. 12 oral presentations and 19 additional poster presentations; 3. a report from each working group discussion on the four hast-rock formations; and 4. a proposal for generic definitions of excavation disturbed and damaged zones and an overall synthesis and conclusions of the conference and workshop. The Cluster EDZ conference was attended by 145 participants from 20 countries (13 European Union Member States and candidate countries, and Switzerland (associated country to the Euratom research and training programme), six third countries (Canada, Croatia, India, Japan, South Africa and the United States of America)), and the OECD/NEA
