In this study, the natural ventilation pressure resulting from the large altitude difference which is a characteristic of high radioactive waste repository and the caloric value of the heat emitted by wastes was calculated and based on the results, natural ventilation quantities were calculated. A high radioactive waste repository can be considered as being operated through closed cycle thermodynamic processes similar to those of thermal engines. The heat produced by the heating of high radioactive wastes in the underground repository is added to the surrounding air, and the air goes up through the upcast vertical shaft due to the added heat while working on its surroundings. Part of the heat added by the work done by the air can be temporarily changed into mechanical energy to promote the air flow. Therefore, if a sustained and powerful heat source exists in the repository, the heat source will naturally enable continued cyclic flows of air. Based on this assumption, the quantity of natural ventilation made during the disposal of high radioactive wastes in a deep geological layer was mathematically calculated and based on the results, natural ventilation pressure of $74{\sim}183$Pa made by the stack effect was identified along with the resultant natural ventilation quantity of $92.5{\sim}147.7m^3/s$. The result of an analysis by CFD was $82{\sim}143m^3/s$ which was very similar to the results obtained by the mathematical method.

The impacts influenced on the performance and safety of a repository are classified as units of Features, Events, and Processes (FEP), for the total system performance assessment (TSPA) related to the permanent disposal of HLW. The importance is evaluated in consideration of the frequency, consequence, regulation, suitability of a specific site, etc. and then these are grouped as a similar FEP. A scenario describing the migration of radionuclide from the repository to the biosphere is derived from understanding the interaction among these groups. KAERI has developed the KAERI FEP lists by review and collation of the foreign studies. The KAERI FEP list has been reviewed by several Korean experts. The five major scenarios describing possible future evolutions of the geological disposal system have been developed by RES and PID methods. Also the CYPRUS which is a KAERI integrated database management system for the total system performance assessment (TSPA) related to the permanent disposal of HLW has been developed and the results of the FEP and scenario development have been uploaded in this system.

산업통상자원부는 5월 26일 행정절차법 제46조에 따라 "고준위방사성폐기물 관리 기본계획(안)"(이하 '기본계획(안)')을 행정 예고했다. 이번 기본계획(안)은 미래 세대를 위해 고준위 방폐물을 안전하게 관리하는 방식과 절차를 담은 사실상 최초의 '중장기 안전 관리 로드맵'으로서, 사용후핵연료 공론화위원회가 고준위 방폐물의 안전 관리의 세부 절차와 틀을 제시한 "권고안"을 바탕으로 정부 차원의 기본 계획을 만든 것이다. 산업부는 이번 기본계획(안)에 대해 6월 중순경 공청회 등 의견 수렴을 거쳐, 7월경 총리주재 원자력진흥위원회를 거쳐 확정할 예정이다. 기본계획(안)은 현재에서 최선의 관리 방식을 선택하면서 현실적 대안도 감안한 것으로, 향후 여건 변화를 반영하여 5년 단위로 보완할 예정이며, 과학 조사, 부지 선정 등 투명한 절차를 담은 (가칭)"고준위방폐물 관리절차에 관한 법률"을 금년중 국회에 제출할 계획이다. 기본계획(안)은 미래 세대를 위해 고준위 방폐물을 안전하게 관리하는 방식과 절차를 주요 내용으로 담고 있으며 세부 내용은 다음과 같다.
