N2 - This work was performed at the outset of the FORGE project (Fate of Repository Gases) in the framework of workpackage WP1.1.
The multiple barrier concept is the cornerstone of all proposed schemes for underground disposal of radioactive wastes. The concept invokes a series of barriers, both engineered and natural, between the waste and the surface. Achieving this concept is the primary objective of all disposal programmes. However, the performance of the repository as a whole (waste, buffer, engineering disturbed zone, host rock), and in particular its gas transport properties, are still poorly understood. This state of art report gave a complete overview of the basic concepts and theories, current treatment and existing uncertainties in PA regarding gas generation and migration in deep geological repository. In detail, it aims at:
-describing the current treatment of gas issues in PA;
-identifying strong points but also weaknesses of the current treatment;
-analysing the limitations of previous studies and uncertainties related to gas generation and transport;
-discussing needs for additional studies of gas migration issues, and their relevance for PA.
