1 Key Information File for Radioactive Waste Repositories Pierre-Henri de La Codre OECD/NEA IAEA Third International Conference on Nuclear Knowledge Management 7-11 November Organisation for Economic Co-operation and Development

2 The NEA: A Forum for Co-operation for the Advanced Countries in the World Missions: To assist its member countries in maintaining and further developing, through international co-operation, the scientific, technological and legal bases required for a safe, environmentally friendly and economical use of nuclear energy for peaceful purposes. To provide authoritative assessments and to forge common understandings on key issues, as input to government decisions on nuclear energy policy, and to broader OECD policy analyses in areas such as energy and sustainable development. Founded in member countries 7 standing technical committees 75 working parties and expert groups 21 international joint projects 122 employees 2015 Organisation for Economic Co-operation and Development 2

4 Records, Knowledge and Memory across generations Purpose: The Records, Knowledge and Memory (RK&M) initiative of the NEA RWMC assembles an international group of RWM specialists to reflect on how best we can enable future members of society to make their own informed decisions regarding a radioactive waste repository after it is closure, decades, centuries and millennia from now Phase-I: Current membership: 21 organisations from 14 Phase-II: countries: ONDRAF/NIRAS (Belgium), SCK (Belgium), NWMO (Canada), SURAO (Czech Republic), STUK (Finland), ANDRA (France), BfS (Germany), GRS (Germany), KIT (Germany), PURAM (Hungary), JAEA (Japan), RWMC (Japan), ROSATOM(Russia), ENRESA (Spain), SKB (Sweden), Riksarkivet (Sweden), SSM (Sweden), NAGRA (Switzerland), SFOE (Switzerland), NDA-RWM (UK), USDOE (USA) Observers: 2015 Organisation for Economic Co-operation and Development 4

5 Radioactive waste management & Records Preservation Aube surface repository Forsmark near-surface repository Deep geological repository DGR are constructed to be there permanently. Record preservation is crucial: Ensure future generations to be aware of its contents / hazards, i.e., able to make informed decisions; Knowledge of hazard will deter inadvertent human intrusion. To increase permanence, a systematic approach using multiple, complementary components should be used to provide redundancy 2015 Organisation for Economic Co-operation and Development 5

6 RK&M Several areas of work: Prevent repository from Human intrusion Marking Strategy Keep the Society aware of the Repository Cultural Heritage International Mechanisms Archiving Knowledge Management Key Information File (KIF) Set of Essential Records (SER) 2015 Organisation for Economic Co-operation and Development 6

7 Level of Details Accessibility Durability Inform by Hierarchical System Points to Key Information File (KIF) A single document providing a summary of the existence, location and content of an engineered facility for the permanent disposal of radioactive wastes Set of Essential Records (SER) A set of of most important records most important records to be kept about the repository history, construction, properties, etc. Many copies distributed widely National, regional or specialized Archive in printed and/or electronic form RECORDS SELECTED FOR STORAGE in accordance with national or local regulations and legislation National, regional or specialized Archive in printed and/or electronic form DETAILED RECORDS > documents Repository site and/or Operator site, Archive and/or data base 2015 Organisation for Economic Co-operation and Development

8 KIF Principles (1/2) 1. The KIF should provide relevant information to future generations, to help protect passive performance of the disposal site and to enable any necessary decision making. 2. The KIF should identify hazards presented by waste, describe reduction in hazard with time, and describe engineered and natural barriers that prevent human contact with radioactive wastes. 3. The KIF should be written, so far as possible, in a succinct and non-technical manner. Where necessary, technical context should be provided to prevent ambiguous interpretations of information Organisation for Economic Co-operation and Development 8

9 KIF Principles (2/2) 4. Copies of the KIF should be preserved in formats and locations that are easily located and viewable, so that it is readily available to all potentially interested parties. 5. The KIF should point to planned preservation of more detailed information about the disposal facility, its content and associated safety cases, noting that additional information is unlikely to have been preserved with the same rigour. 6. The KIF should not be over 40 pages Organisation for Economic Co-operation and Development

10 The KIF Table of Content Section Title and Contents 0. Purpose and contents of this document (to be provided in several languages) 1. Disposal Context 2. Facility Location 3. Container and Facility Design 4. Disposal Inventory 5. Safety Case 6. Disposal Records 7. List of similar repositories in the world (to be provided in several languages) 2015 Organisation for Economic Co-operation and Development 10

11 Testing the KIF The KIF is currently being tested in three different cases The closed French Centre de stockage de la Manche (surface repository) The existing US Waste Isolation Pilot Plant WIPP (geological) The planned Swedish Spent Fuel Repository (geological) Feedback is wanted on: What should be the core contents of the KIF, is anything of importance missing? Who should be responsible for making the KIF? Who should take care of/look after and use the KIF? 2015 Organisation for Economic Co-operation and Development 11

12 Next Steps Integration of the three tests Feedbacks mentioned in the previous slide Feedback on the best way to fill in the KIF Issue a final report by April 2017 Same work for the SER Draft list of documents Testing Final report 2015 Organisation for Economic Co-operation and Development 12
