The regulation for the low and intermediate level radioactive waste to be transferred to the disposal facility, recently revised, require that radioactive waste generators should set up waste certification program to verify the radioactive waste conform to the waste acceptance criteria(WAC) before disposal. The radioactive waste disposal facility, scheduled to be constructed in Korea, will institute WAC for the wastes to be transferred to the facility. This WAC is expected to compose of the requirements for the radiological characterization, physical and chemical characterization, physical/chemical restriction, prohibited item, packaging, identification, labeling, and documentation. For the compliance with this regulation, The radioactive waste generators should verify that the waste meet WAC through performance of the waste certification program and are responsible for handing in all the certification documents to the disposal facility. This waste certification program plan was set up as a preliminary program for the certification of radioactive waste generated in Korea Atomic Energy Research Institute (KAERI) and should be further revised until preparation of WAC by disposal agent.

The inventory management of radionuclides is essential for the safe management of disposal facilities. In this study, we compared the activity of dry active waste predicted using the generated waste data and that measured for the accepted waste in the disposal facility. For very low level waste, the measured activity was higher than the predicted activity for $^{137}CS$, $^{90}Sr$, $^{99}Tc$ and $^{129}I$. In low level waste, the predicted activity was higher than the measured activity for all radionuclides. We also evaluated the variation in the predicted quantity and total activity of each level of dry active waste through a sensitivity analysis on a scaling factor. This result will contribute to the construction of a Safety Case and safe operation of disposal facilities.

본 연구는 방사성폐기물 처분시설(radioactive waste repository)의 입지를 가정하여, 처분시설이 경상북도 경주시에 발생시키는 경제적, 사회적 효과를 분석하는데 목적이 있다. 정부는 처분장 유치의 유인책(incentives)으로서 경주 지역주민들을 위하여 다양한 정책적 수단을 마련하였다. 처분시설 입지에 따른 특별지원금 3,000 억원 지원, 수거물 반입 수수료 지원(년당 50-100억원), 한국수력원자력(주) 본사이전, 양성자가속기 사업 추진 등이 그것이다. 이들 지원사업들이 가져오는 변화를 시스템 다이내믹스(System Dynamics) 기법을 적용하여 지역사회의 인구, 산업, 토지, SOC, 지방재정 등이 어떻게 변화하는지 추적해 봄으로써 도시체제의 동태성(urban system dynamics)을 이해하고 처분장 시설이 지역에 입지했을때, 미래에 발생 가능한 문제점이 없는지 밝혀내고자한다. 이를 위하여 시뮬레이션 모델링에 입지 지역의 특성과 현황을 반영하여 처분장입지에 따른 지역의 동태적인 변화과정과 경향을 추정해 보고, 현재 예정되어 있는 지원사업이 충분한지, 이외에 다른 정책적 지원이 필요한지를 알아본다. 본 연구의 의미는 이처럼 경주지역 주민들이 처분장의 지역입지를 만족스럽게 행각하고 소외감 없이 생활을 영위할 수 있도록 정책적 지원 프로그램을 작성하는데 기초가 되는 연구라는 점에 있다고 하겠다.

The low and intermediate-level radioactive waste generated in Korea is disposed of at Wolsong Disposal Facility. For the safety of a disposal facility, it must be assessed by considering some abnormal scenarios including human intrusion as well as those by natural phenomena. The human intrusion scenario is a scenario that an incognizant man of the disposal facility will be occurred by the drilling. In this paper, the well usage scenario was classified into the human intrusion event as the probability of the well drilling is very low during the man's lifecycle and then was assessed by using conservative assumptions. This scenario was assessed using the dilution factor of contaminants released from a disposal facility and then it was introduced the applied methodology in this study. The assessed scenario using this methodology is satisfied the regulatory limits.

The repository for the disposal of LILW which is generated from nuclear power plants and industries is expected to be completed in 2014. For the disposal of LILW, it is important to secure a disposal facility itself, but it is also very important to establish a reasonable charging system which all shareholders are satisfied with. Korea's disposal fee for LILW is higher than other countries' fee, which is a burden to waste generators as well as the waste management organization. The partial reason for the high disposal fee is put on the high social and construction cost when compared with other countries. However the major reason is put on the excessive borrowing cost that is used for the construction of the LILW disposal facility. In this study, we proposed the way to reduce the excessive borrowing cost for sustainable project managements of LILW disposal by analyzing a cost structure.
