Abstract

In underground repositories for radioactive waste, significant quantities of gases may be generated as a result of several processes, notably the interaction of groundwater's and brines with waste and engineered materials placed in disposal systems. The potential impact of gas generation, accumulation and migration on the long-term safety of a repository will be dependent upon the waste types, the repository concept, the host geological environment and the scenarios for long-term evolution of the system. Significant efforts have been, and continue to be expended in numerous national and international programmes in investigating the processes and analyzing potential impacts on the long-term safety.

In the light of these efforts, and in order to help focus further work, the European Commission and the OECD/Nuclear Energy Agency have jointly instigated a review of the knowledge gained so far. This has established the current status of the basic understanding of the topics concerned. Moreover, the treatments that have been accorded to the gas issues in published performance assessments are reviewed.
