IAEA 7 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.

IAEA 11 In order to provide additional guidance on the level of depth and detail warranted for safety cases, it was proposed that the IAEA would develop illustrative safety reports with example safety cases -> CRAFT PROJECT DS284: Proposal to June 2010 WASSC for Approval

IAEA 12 International Intercomparison and Harmonization Projects CRAFT (successor to SADRWMS) SADRWMS Methodology and SAFRAN Tool Illustrative examples to complement SG (DS284) PRISM Safety case Barrier performance WAC Uncertainty GEOSAF Regulatory expectations throughout development and operation Review process Assessment – engineering, site, radiological impact, integration Working Group for the Dual Use Cask for Spent Nuclear Fuel Safety case extended periods of storage and meeting transport requirements

IAEA 13 Objectives: 1. EXAMINE the application of safety assessment methodology (ISAM, ASAM) 2. DEVELOP, document Safety Assessment Methodology Regulatory Review ---> DS284… 3. INTEGRATE methodology into software tool (SAFRAN) SADRWMS Project Safety Assessment Driving Radioactive Waste Management Solutions Safety Case & Assessment Predisposal DS 284
