The concept of removing long-lived radioactive wastes from the human environment by disposal in deep geological repositories was developed several decades ago. In the intervening years, research efforts world-wide have increased our knowledge and understanding of how underground disposal systems...

A key challenge in the development of safety cases for the deep geological disposal of radioactive waste is handling the long time frame over which the radioactive waste remains hazardous. The intrinsic hazard of the waste decreases with time, but some hazard remains for extremely long periods....

L’idée d’isoler de l’environnement humain les déchets radioactifs à vie longue en les stockant dans des dépôts profonds remonte à plusieurs décennies. Depuis, les recherches réalisées dans le monde ont renforcé nos connaissances et notre compréhension du fonctionnement des...
