Status of the IAEA safety standards and Relation to the CRAFT project Monika Kinker Radioactive Waste and Spent Fuel Management Unit Division of Radiation, Transport and Waste Safety - NSRW

Structure of the Safety Standards In 2008 a new, long-term structure for the safety standards was adopted. This structure is such that users may easily identify those safety standards that are applicable to the specific facility or activity they are dealing with. The Safety Fundamentals (SF-1), the General Safety Requirements (GSR) in seven parts and the General Safety Guides (GSG) are applicable to all facilities and activities. These are complemented by Specific Safety Requirements (SSR) and Specific Safety Guides (SSG), which are applicable to specified facilities and activities. The transition to this new structure is currently underway. Information on the current status of development of each standard and more detail on the structure is available on the IAEA website http://www-ns.iaea.org/downloads/standards/status.pdf 2 2

IAEA Terminology regarding the Safety Case, Safety Assessment … GSR Part 5, DS284: Safety Case A collection of arguments and evidence in support of the safety of a facility or activity. This will normally include the findings of a safety assessment and a statement of confidence in these findings. GSR Part 4 , DS284: Safety Assessment 1. Assessment of all aspects of a practice that are relevant to protection and safety; includes siting, design & operation of the facility. This normally includes risk assessment and probabilistic SA. 2. Analysis to predict the performance of an overall system and its impact, where the performance measure is the radiological impact or some other global measure of the impact on safety.
