This report documents that topical session, which was meant to provide an exchange of information and experience on the following issues: What topics should be included in a safety case? Of what should it consist? Is there sufficient and complete guidance nationally and internationally? How do practices differ internationally? The discussion was limited to plants where spent fuel has been removed.
