14 IAEA TM on disposal of ILW Korea LILW Repository

15 IAEA TM on disposal of ILW Located in the south-east coast of Korean peninsula - Adjacent to Wolsong NPP Area : about 2,000,000 sq. m Overview of LILW Disposal Site Overview of LILW Disposal Site underground silo type/150~200 m below surface Disposal capacity : total 800,000 waste packages (100,000 packages for the 1 st stage) Wolsong#1,2,3,4 Shin-Wolsong #1,#2 LILW disposal site (2.0 km 2 ) 15

16 IAEA TM on disposal of ILW 16 Wolsong LILW Disposal Site has been under construction since August 2008. Operation of all facilities is planned to begin in July 2014 LILW Disposal Site 16

21 IAEA TM on disposal of ILW LILW Disposal Facility Project Milestone Designation as LILW Disposal Facility Site Jan. 2006 Detailed Site Investigation & Design Feb. 2006 Disposal Method (1 st Stage : Underground Silo Type) Jul. 2006 Application for Construction & Operating License Jan. 2007 Issued Construction & Operating License Jul. 2008 Jun. 2014 Full Operation of the Facility Operation of LILW Reception/Storage Buildings Dec. 2010 21

22 IAEA TM on disposal of ILW 22 Post-closure SA Criteria for LILW Disposal The predicted annual radiological dose caused by natural evolution on individuals of critical group shall not exceed 0.1 mSv. Annual risk due to unexpected disruptive events caused by either natural or artificial factors shall be limited to below 10 -6. After the institutional control of disposal facilities, radiological impacts due to human intrusion shall be limited below 1mSv/y. Normal evolution Performance Objective caused by natural evolution: 0.1 mSv/y Disruptive events Risk induced by un-controlled natural or man-made dispuptive events : 10 -6 /y Human Intrusion Radiation dose : 1.0 mSv/y

23 IAEA TM on disposal of ILW 23 Post-closure SA & Institutional Control BiosphereGeosphere Waste Disposal Container BackfillSilo Near Field Not requested to exceed 1,000 y If no peak by 1,000 y, need to demonstrate non-drastic increase of the release rate and non-acute radiological risk to be demonstrated. Timeframe Post-closure Institutional Control Proposed institutional control period: 100 y based on the results of SA Effectiveness of the control period: to be re-verified by safety reassessment, renewal of safety analysis, institutional control plan, and institutional control termination plan, etc.

24 IAEA TM on disposal of ILW Future plan

25 IAEA TM on disposal of ILW Development of 2 nd stage disposal facility 2 nd stage: near surface facility engineered barriers 125 thousands packages Milestone (in planning) In late 2014, apply for license In early 2017, start its operation

26 IAEA TM on disposal of ILW In order to revise the current RW classification system in taking account to the current status & prediction of RW Management based on IAEA GSG-1, the research project by KINS has been launched in 2012. The connection between the RW classification and the disposal type would be the key factors in this research. It is likely that the revision of RW classification system in legal framework would be done based on this research. Revision of RW classification system 26

27 IAEA TM on disposal of ILW Current System 27 HLW (SNF) Geological Disposal (in the future) ILW LLW VLLW Near Surface Disposal (Surface landfill / Engineered Barrier) Intermediate Depth Disposal (??) Geological Disposal (in the future) HLW (SNF) L&ILW VS Future System

28 IAEA TM on disposal of ILW The SA of the LILW repository in Korea guaranteed the long- term safety in showing the compliance with the post-closure performance criteria. Korean LILW repository is now under construction and expected to start its operation in July 2014. KORAD, which is responsible for RWM in Korea, is planning to develop the 2 nd stage of RW disposal facility in Wolsong site. It is expected to be a near surface disposal facility with engineered barriers. New RW classification system is under research by KINS in taking into account the linkage between the category and disposal type based on the long-term safety. Summary 28
