Abstract

As an alternative of the high-level radioactive waste disposal in the subsurface repository, a deep borehole disposal is reviewed by several nuclear advanced countries. In this study, the state of the art on the borehole disposal researches was reviewed, and the possibility of borehole disposal in Korean peninsula was discussed. In the deep borehole disposal concept radioactive waste is disposed at the section of 3 - 5km depth in a deep borehole, and it has known that it has advantages in performance and cost due to the layered structure of deep groundwater and small surface disposal facility. The results show that it is necessary to acquisite data on deep geologic conditions of Korean peninsula, and to research the engineering barrier system, numerical modeling tools and disposal techniques for deep borehole disposal.

고준위폐기물 처분과 관련하여, 최근 저장소 형태의 처분장 개념에 대한 대안으로 검토되고 있는 시추공 처분 개념에 대한 연구 현황을 정리하고 시추공 처분 개념의 국내 적용 가능성과 필요한 연구 항목에 대해 논의하였다. 현재 미국과 스웨덴을 중심으로 논의된 시추공 처분 개념은 심부시추공을 설치하여 지하 3 - 5km 구간에 고준위폐기물을 처분하는 것을 의미하며, 현재까지의 연구 결과에 의하면 이 처분 개념은 심부지하수의 층상구조, 작은 규모의 지표시설 등으로 인해 처분 및 비용 효율이 클 것으로 예상된다. 이에 반해 국내에는 축적된 심부 지질 자료가 없어 적용 가능성에 대한 논의할 여지가 없다. 이에 저장소 형태의 처분장 개념에 대한 대안으로 시추공 처분 개념을 검토하기 위해서는 향후 심지층 자료 확보, 공학적 방벽 연구, 수치모의모델 개발, 처분 기술 개발 등의 연구가 필요하다.
