SITEX WP2.1 NEEDS FOR TECHNICAL GUIDANCE F. Lemy- F. Bernier - GEOSAF II TM – SITEX WP2.1 – 28/05/2014
SITEX Project • Main objective: To define the conditions and means for establishing a coordinatedEuropean (and possibly international) workforceensuring a sustainablecapability to provide a technical and independent expertise in the field of radwaste management safety and radiological protection • December 2011 – December 2013 • http://sitexproject.eu/ GEOSAF II TM – SITEX WP2.1 – 28/05/2014 2
SITEX WPs WP2: Needs for guidance and technical support WP4: Needs for review guidance and training WP6 Missions of the future European network of experts WP3: Needs for R&D and opportunities for joint programming WP5: Conditions for interacting with civil society GEOSAF II TM – SITEX WP2.1 – 28/05/2014
WP2 Objective To set up the conditions for allowing mutual understanding between National Safety Authorities (NSAs), Technical Safety Organisations (TSOs) and Waste Management Organisations (WMOs) GEOSAF II TM – SITEX WP2.1 – 28/05/2014

Regulatory expectations (WP2.1) WP2.1 Context: Responsibilities of the Regulatory Body Requirement 2 of IAEA SSR-5: The regulatory body shall a.o.: • establishregulatory requirementsfor the development of different types of disposal facility for radioactive waste • undertake international cooperation, as necessary, to fulfil its regulatory functions • provide guidanceon: • the interpretation of the national legislation and regulatory requirements as necessary • what is expected of the operator GEOSAF II TM – SITEX WP2.1 – 28/05/2014

WP2.1 Deliverable • Title: “Overview of existing technical guides and further development” • Description: An overview of existing technical guides including an identification of: • common points and differences • the needs for further development, harmonization and dialogue • Soon available !

WP2.1 Working Hypotheses (1/2) 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 requirementsagainstwhich the situation of each country isassessed • Engagement to transpose SRLs into national regulatory frameworks of WENRA member states • IAEA Safety Fundamentals and Requirements • ICRP recommendations GEOSAF II TM – SITEX WP2.1 – 28/05/2014 13
WP2.1 Working Hypotheses (2/2) 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 GEOSAF II TM – SITEX WP2.1 – 28/05/2014 14
Safety Topics (1/4) 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” GEOSAF II TM – SITEX WP2.1 – 28/05/2014 15
Safety Topics (2/4) • Management system: • Organisational structure • Resources • Process implementation (including QA) • … GEOSAF II TM – SITEX WP2.1 – 28/05/2014 16
Safety Topics (3/4) • Site selection • Design • Construction • Operation • Closure & Decommissioning • Period after closure and institutional controls • Waste acceptance • Monitoring Requirementsassociatedwithspecific phase(s) of repositorydevelopment GEOSAF II TM – SITEX WP2.1 – 28/05/2014 17
Safety Topics (4/4) • 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 GEOSAF II TM – SITEX WP2.1 – 28/05/2014 18
Operation: Sub-topics • Investigations and feedback of information on operating experience • Operational limits and conditions • Modifications • Emergency preparedness and response • Maintenance, periodic testing and inspection • Occupational exposure • Public exposure • Receiving, handling and emplacement of waste GEOSAF II TM – SITEX WP2.1 – 28/05/2014
Safety Topics vs. Requirements Example: Requirementsassociatedwith the safety topic “Construction” GEOSAF II TM – SITEX WP2.1 – 28/05/2014 20
Identification of the Needs of NSAs & TSOs Needs of NSAs/TSOs for guidance development and/or dialogue have been identifiedbased on: • Questionnaire on existing, used and neededguidance • Comparisonof existingtechnicalguides Theseneeds have been prioritizedconsidering the level of « urgency », importance for safety, the level of interest,… GEOSAF II TM – SITEX WP2.1 – 28/05/2014 21
Prioritization the NSAs & TSOs Needs • ~100 needswereidentified !!! • 35 needsidentified 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 GEOSAF II TM – SITEX WP2.1 – 28/05/2014 22
Identified Needs: Construction GEOSAF II TM – SITEX WP2.1 – 28/05/2014
Identified Needs: Operation (1/2) GEOSAF II TM – SITEX WP2.1 – 28/05/2014
Identified Needs: Operation (2/2) GEOSAF II TM – SITEX WP2.1 – 28/05/2014
Conclusions • 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 26
