CONFIDENCE BUILDING IN BIOSPHERE ASSESSMENT INVOLVING ENVIRONMENTAL CHANGE - A REGULATORY PERSPECTIVE

摘要

Several countries consider geological repositories as the preferred option for the final management of spent nuclear fuel, due to their potential to provide isolation from the surface environment on very long timescales. In post-closure radiological assessments of geological disposal of radioactive waste, the complexity of the assessment may increase as the site investigation program produces more extensive site data. In addition, consideration of climate change and its impact on the future evolution of the site will add complexity to the assessment. With this paper the Swedish Radiation Safety Authority (SSM) wants to describe the authority's review of the dose assessment in a post-closure safety assessment for the license application for construction of a geological repository. And how SSM has tried to disseminate this experience internationally. Emphasizing the importance of explanatory power to gain confidence from authorities and the public.
