A thematic network on gas issues in safety assessment of deep repositories for radioactive waste (GASNET). Final report on the treatment in safety assessments of issues arising from gas generation
Project ID: FIKW-CT-2001-20165Funded under: FP5-EAECTP C
Gas is expected to be generated in underground repositories for radioactive wastes. The generation rates and quantities of gas that are expected to be produced will vary with waste type and repository concept, but issues arising from gas generation need to be addressed in safety cases for all repositories, since they cannot be ruled out a priori for any repository type or concept. This report documents current approaches to the treatment of gas issues in the context of a safety case for a deep repository and discusses the strengths and limitations of these approaches, where appropriate. The emphasis is primarily on the requirements of safety cases rather than on reviewing understanding of gas generation and migration processes, as the latter has been dealt with recently elsewhere.
