Abstract

Geology, hydrogeology, and geochemistry are the main technical siting factors of a geological repository for spent nuclear fuels. This paper focused on how rock's different geological conditions, such as topography, soils, rock types, structural geology, and geological events, influence the functions of the geological repository. In the context, the site selection criteria of various countries were analyzed with respect to the geological conditions. Each country established the criteria based on its important geological backgrounds. For example, it was necessary for Sweden to take into account the effect of ice age on the land uplift and sea level change, whereas Japan defined seismic activity and volcanism as the main siting factors of the geological repository. Therefore, the results of the paper seems to be helpful in preparing the siting criteria of geological repository in Korea.

본 연구에서는 심지층 처분장 부지선정 시에 고려되는 요소를 지질, 수리지질, 지화학 등으로 분류하고 그 첫 번째 단계로 지질분야의 세부 항목을 지형, 토양층, 암종, 구조지질, 역학적 안정성, 지질학적사건으로 분류하였으며, 이들 항목에 대한 국외 기준분석을 수행하였다. 부지선정요소(Siting factor)에 대한 기준(Criteria)은 각 국가의 처한 지질환경에 따라 다른 조건 혹은 값을 제시하고 있다. 화산 및 지진활동이 빈번한 일본에서는 이에 대한 기준을 상대적으로 자세히 기술하고 있으며, 빙하작용이 예상되는 스웨덴에서는 빙하작용에 의한 지반 융기 침식에 대한 영향을 상세히 분석하였다. 따라서, 본 논문 결과는 향후 국내의 심지층 처분장 부지선정 기준 수립시에 중요한 참고자료로 활용될 수 있을 것으로 판단된다.
