5 NEA Mission 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.

12 Principles of Decommissioning Decommissioning does not present major technical challenges. There is a sound technical base for executing decommissioning work. However, experience with completed decommissioning projects is limited. There is, therefore, uncertainty regarding the costs of decommissioning specific facilities Organisation for Economic Co-operation and Development 12

13 Decommissioning of Nuclear Power Reactors and Expected Shutdowns In operation Shutdown/under decommissioning Fully decommissioned Nuclear Power Reactors Worldwide Country Permanent Shut Down* Decommissioning completed NPR In Operation Add l Shut Down before 2030* U.S.A Canada Korea Japan * Based on PRIS database (July 2016) ** General assumption - shutdown after 40 years operational time (except US, where most reactors will operate at least 60 years) 2016 Organisation for Economic Co-operation and Development 13

14 Principles of Decommissioning Decommissioning does not present major technical challenges. There is a sound technical base for executing decommissioning work. However, experience with completed decommissioning projects is limited. There is, therefore, uncertainty regarding the costs of decommissioning specific facilities. Evolving circumstances and requirements in several countries further complicate the development of good estimates: Some plants are being shutdown earlier than expected Prompt decommissioning is becoming more common Some countries are requiring greenfield outcomes 2016 Organisation for Economic Co-operation and Development 14

15 Some Challenges Understanding of the complex interrelationships in a decommissioning project and setting the right course for safe and cost efficient decommissioning Availability of waste management and disposal pathway Sufficient decommissioning funding Availability of resources Managing the change of responsibilities and culture Maturity of technical solutions 2016 Organisation for Economic Co-operation and Development 15

17 Funding for Decommissioning All countries much assure the adequacy of financing arrangements for future decommissioning projects Decommissioning funding mechanisms differ from country to country. There is no single best system Polluter Pays principle remains generally valid All NEA countries should have a program that is both reasonable and workable There are considerable uncertainties when planning for decommissioning: Changing financial markets Evolving governmental policies Changing conditions and requirements 2016 Organisation for Economic Co-operation and Development 17

18 Decommissioning Cost Estimates Example: Lubmin and Rheinsberg NPPs, Germany Date Cost Estimation Boundary Conditions 1994 ~ 3.2 billion Euros Decommissioning strategy: immediate dismantling End state green field expected in > 4 billion Euros ~2.5 billion Euros already spent until ~ 4.2 billion Euros ~3.1 billion Euros already spent until ~ 6.5 billion Euros ~ 3.2 billion Euros already spent Change of decommissioning strategy to save costs: immediate dismantling & safe enclosure (50 years) End state green field expected ~2065 Outlook: Main decommissioning activities to be completed in 2015 (immediate dismantling) End state green field expected ~2065 Return to decommissioning strategy immediate dismantling End state green field expected in 2028 Decommissioning scope: Lubmin NPP: 5 PWR, VVER-440s (440 MWe each), operation: Rheinsberg NPP: 1 PWR, VVER-210 (70 MWe), operation: Organisation for Economic Co-operation and Development 18

26 Expert Groups Example TGPFD Modus Operandi Mandate for 2 years basing on Terms of Reference (scope, methodology, remits; 2 meetings/year) Participation: open to any expert nominated by NEA member countries (with approval by their country delegation to OECD): 25 members from 25 organisations and 9 countries Role of TGPFD To provide member countries with up-to-date information and develop consensus regarding strategic aspects of optimisation of activities and measures with regard to the preparation for D&D. To keep under review relevant worldwide experience and identify and examine pertinent issues of interest to its members, to the WPDD and to the international community. Remit To foster exchange of international experiences, strategic approaches, risks and opportunities between its members on issues concerning preparation of a nuclear facility for D&D. To produce a report containing observations and recommendations to be considered in the development and optimisation of strategies and plans for preparation for decommissioning in order to support on-going and new decommissioning projects, to achieve value for money, safety of workers and improvements in project management consistent with best practice and which enable the timely delivery of decommissioning targets Organisation for Economic Co-operation and Development 26

27 Recommendations from TGPFD considerations An early understanding of the decommissioning drivers and the target interim and end states will heavily influence the choices made approaches taken in preparation for decommissioning Site Characterisation: A detailed radioactive waste inventory will help to define process/treatment, packaging and disposal requirements and can help target early R+D projects. Immediate post-shutdown activities can reduce demand on assets through risk and hazard reduction, which will translate into significant cost savings over the remaining facility life A Waste Management Strategy that takes into account the full remaining lifecycle is recommended.

35 Conclusions Good reasons for International Experience Exchange and Co-operation: To ensure that the safest, most economic and environmentally-friendly options for decommissioning are employed. For those with less experience: benefit in not having to go through an expensive learning and development programme Dialog between different stakeholders with different expertise, different point of views, between different generations: Sharing of experience basing on Give&Take and developing a common understanding Networking: experience exchange is not only restricted to meetings only We owe it to ourselves and to future generations to deal with radioactive materials and waste in a safe and environmentally responsible manner. Societal support for decommissioning is fostered through dialogue and rests on confidence that decommissioning is technologically sound and that safety can be demonstrated convincingly. 1 NEA invites all interested to join its initiatives and expert groups for international experience exchange and co-operation! 1 Source: NEA Flyer Working Party on Decommissioning and Dismantling, Organisation for Economic Co-operation and Development 35
