Table 3. Assumed cases for the conceivable NPPs deployment scenario in the ROK
I. ROK nuclear power plants deployment scenario (cont’)
Case Assumption
Case 1 No replacement of NPPs once they are decommissioned
Case 2 Replacement of NPPs with decommissioned ones in 10 years after shutdown by 2050 (1.4GWe PWRs for decommissioned PWRs while 0.7 Gwe CANDUs for decommissioned CANDUs)
Case 3 Replacement of NPPs with decommissioned ones in 10 years after shutdown by 2050 (1.4GWe PWRs for decommissioned PWRs and CANDUs)
Case 4 In addition to Case 3, further deployment of eight 1.4GWe PWRs since 2017 (one in each year) (i.e., +4 units at Kori, +2 units at Ulchin, +2 units at Wolsong)

Table 5. Functions of the authority bodies regarding spent fuel management in the ROK
Authority Functions
NEC Decision making authority in national energy and spent fuel management under the ROK President
MOCIE Supporting NEC and controlling KHNP
KHNP Storage of spent fuel
AEC Decision making authority in nuclear energy research and development under the ROK Prime Minister
MOST Supporting AEC and controlling KAERI
KAERI Nuclear research and development, including R&D, so called advanced nuclear fuel cycles
III. Recent issues in the ROK spent fuel management (cont’)
• The National Energy Committee (NEC), chaired by the ROK president, established in November 2006, will examine plans for the spent fuel management. The Radwaste Management Division of MOCIE will support the NEC for the work of the spent fuel management. MOCIE appears has not shown much interest in recycling spent fuel.
• On the other hand, MOST has recently shown much interest in recycling spent fuel, especially in pyroprocessing. I think the operation of Rokkasho reprocessing plants and GNEP influenced in strengthening the MOST’s stance on the recycling policy.
IV. Concluding remarks
• The ROK should prepare an alternative to acquire additional storage capacity its spent fuel as pools of NPPs sites are running out of their storage capacities roughly within a decade.
• The newly established National Energy Committee will evaluate alternatives and make policy decisions for the long-term spent fuel management in the ROK.
