[Les proprietés des Argiles à Opalinus étudiées au laboratoire souterrain du Mont Terri en Suisse]
In the Mont Terri Rock Laboratory, eleven organisations from six countries (ANDRA and IPSN from France) are investigating jointly a Mesozoic shale formation, the Opalinus Clay. The aims of the research programme are to analyse its hydrogeological, geochemical and rock mechanical properties, the changes induced by the excavation of galleries, by heat-generating waste and by engineered barriers, and to evaluate and improve appropriate investigation techniques. The results of a series of experiments indicate that, at a convenient site, the investigated or similar clay formations could be favourable for hosting a safe repository for radioactive waste.
Dans le laboratoire souterrain du Mont Terri, onze organisations de six pays (de France : ANDRA et IPSN) se sont réunies pour étudier les caractéristiques d'une formation argileuse du Mésozoı̈que, les Argiles à Opalinus. Les objectifs du programme de recherche sont d'analyser leurs propriétés hydrogéologiques, géochimiques et géomécaniques, les changements induits par l'excavation de galeries, par des déchets dégageant de la chaleur et des barrières ouvragées, et d'évaluer et d'améliorer les techniques de recherche appropriées. Les résultats d'une première série d'expériences indiquent que, sur un site favorable, la formation argileuse étudiée et des formations comparables pourrait convenir à accueillir un dépôt de déchets radioactifs.
