WP2.1 Deliverable 11 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

12. Identification of the areas where technical guidance and dialogue are needed in priority WP 2.1 TARGET Safety requirements (WENRA, IAEA,…) Common points & differences Existing regulatory guides IGD-TP vision Safety Topic List Overview of existing regulatory guides Exchanges with IGD-TP & Civil Society A priori identification of development needs Needs for further development, harmonization and dialogue WP2.1 Inputs WP2.1 Steps 12 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

13. Safety requirements on which international consensus exists are taken as reference: EC Directive on SF & Radioactive Waste Management (2011/70/Euratom) Draft WENRA Safety Reference Levels (SRLs) – Set of requirements against which the situation of each country is assessed – Engagement to transpose SRLs into national regulatory frameworks of WENRA member states IAEA Safety Fundamentals and Requirements ICRP recommendations WP2.1 Working Hypotheses (1/2) 13 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

14. Technical guidance: associated with one or several safety requirements may serve different purposes: – Interpretation of requirements – Explanation of how requirements can be met in practice and/or how compliance should be substantiated – Facilitate dialogue and interactions with the public or with other stakeholders possible audiences: implementers, experts fulfilling an expertise or a regulatory function, public or other stakeholders WP2.1 Working Hypotheses (2/2) 14 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

15. Safety topics identified based on existing “high-level” safety requirements: Governing principles: – Radiation protection principles – Protection of present and future generations – Defence in Depth & Robustness – Demonstrability & Feasibility –…–… Safety policy & strategy: – Safety strategy: “High-level approach for achieving safe disposal” – addresses the implementation of the “governing principles” Safety Topics (1/4) 15 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

16. Management system: – Organisational structure – Resources – Process implementation (including QA) – … Safety Topics (2/4) 16 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

17. Site selection Design Construction Operation Closure & Decommissioning Period after closure and institutional controls Waste acceptance Monitoring Safety Topics (3/4) 17 Requirements associated with specific phase(s) of repository development 17GEOSAF II TM – SITEX WP2.1 – 28/05/2014

18. Safety case and assessment: – Objectives and scope, Graded approach, SC/SA content vs. regulatory decision steps – Characterisation, knowledge and system understanding – SA methodologies, approaches & tools: Timescales and timeframes, uncertainties, deterministic vs. probabilistic approaches, scenario development, models,… – Indicators & criteria – Operational safety assessment – Long-term safety assessment – Periodic safety review – Independent verification Safety Topics (4/4) 18 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

21. Needs of NSAs/TSOs for guidance development and/or dialogue have been identified based on: Questionnaire on existing, used and needed guidance Comparison of existing technical guides These needs have been prioritized considering the level of « urgency », importance for safety, the level of interest,… Identification of the Needs of NSAs & TSOs 21 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

22. ~100 needs were identified !!! 35 needs identified as having a high level of interest and urgency, e.g.: – Development of the “design basis”, including the consideration of : normal and anticipated operational conditions & possible accidents disturbing FEPs during operation whose consequences may affect post-closure safety – Hazards associated with concurrent activities Prioritization the NSAs & TSOs Needs 22 GEOSAF II TM – SITEX WP2.1 – 28/05/2014

23. Identified Needs: Construction 1 Implication of constraints associated with nuclear safety on the management of construction activities (including construction procedures, quality control,…) 2Information that shall be gathered during construction 3 Approach to deal with design modifications that may occur during construction 23GEOSAF II TM – SITEX WP2.1 – 28/05/2014

25. Identified Needs: Operation (2/2) 5 Operating limits and conditions (OLCs): How to establish and substantiate OLCs, how to maintain OLCs to ensure compliance with end-state, how to meet OLCs and assurances that they are being met, feedback from other (nuclear) facilities,… 6 Modifications of design, waste acceptance criteria, structures, systems and components (SSCs), operational limits and conditions (OLCs) and operational procedures and methods 7 Emergency preparedness: Feedback from emergency plans existing in mines, tunnels and other non-nuclear underground facilities,… 8Ensuring post-closure safety during operation 25GEOSAF II TM – SITEX WP2.1 – 28/05/2014

26. Conclusions 26 WP2.1 was mainly aimed at: fostering mutual understanding and dialogue between NSAs, TSOs and WMOs identifying and anticipating the needs for technical guidance Safety requirements, technical guides and needs associated with the construction, operation & closure of a GDF have been identified Deliverable soon available GEOSAF II TM – SITEX WP2.1 – 28/05/2014
