21 IV. Public Engagement on SNF Management Policy 25

22 History of SNF Management Policy Atomic Energy Commission (Jul. 1988) - Constructing centralized interim storage by the end of Dec AEC (Jul.1998) - Constructing centralized interim storage by 2016 AEC (Dec. 2004) - Separation of site for LILW repository and SNF Interim storage facility - Storing SNF at reactor sites by 2016 by expanding temporary storage - Consent-based national policy should be made with consideration of international trend, R&D, etc. AEC (Dec. 2012) - Launch of the public engagement program from

23 Progress of Stakeholder Consensus Apr. 08 Dec. 09 Dec. 09 ~Aug. 11 Nov. 11 ~Aug. 12 Nov. 12 Oct. 13 ~Jun. 15 Recommendation on public engagement for SNF management by public engagement TF team led by Govrnment Establishment of legal basis upon public engagement by revision of the Radioactive Waste Management Act Consideration of technical options for SNF management Submission of 14 recommendations on SNF management policy - making by SNF Policy Forum(led by private sector) Approval of the implementation plan for SNF management measures by the AEC Recommendation by public engagement commission on Spent Nuclear Fuel (PECOS) 27

24 Framework of Public Engagement Program MOTIE Authorization to PECOS Decision-making with recommendation of PECOS Support Submission PECOS Determination on PE implementation plan Recommendation after PE Program Implementation - Focused on feasible options including interim storage, but not defining certain topics - Submission of recommendation to MOTIE after in-depth review and analysis of public consultation and discussion results Use of Program Results - Respect of Public Engagement Program results as much as possible - Establishment of National Basic Plan for Radioactive Waste Management (Needs approval of AEC) 28

25 10 Recommendations by PECOS (Jun. 15) 1. Top priority on safety, management under governmental responsibilities, and use of proven technologies to avoid undue burden to future generations 2. Prompt efforts to prepare for the transport of SNF to more stable storage facilities before saturation of the existing temporary storage capacity 3. Prompt efforts to develop a geologic disposal facility by 2051, URL construction at the same site by 2020 and in-situ test started from A new environment monitoring center by residents to providing with financial supports in the siting area 5. Prompt efforts to develop a storage-before-disposal facility in the URL site, and on-site short-term storage, when inevitable. 6. A new residents foundation for paying SNF storage fee in case on-site shortterm storage is available 7. Prompt efforts to set-up and implement RD&D program for SNF management technologies 8. A new organization dedicated solely to implementing SNF management project and RD&D program 9. A new specialized law for SNF management for assuring transparency, stability, and sustainability 10. Prompt efforts to establish governmental offices for implementing and deciding SNF management policy 29

26 V. Summary 30

27 Summary Safety is the most important fundamental objective of the national RWM program in Korea. RWM could be more effectively and transparently proceeded by establishment of the KORAD, separated from the NPP Operator. For LILW disposal, the construction of the underground silo type facility was completed in June Currently, KORAD is under preparation of the 2 nd engineered vault type disposal facility. Based on the new RW classification, a basic plan for national LILW management and its implementation plan were setup in PECOS finalized the recommendation report, which was submitted to the government by the end of June KORAD is continuing the efforts, including R&D activities, toward successful implementation of the national RWM program. 31
