Abstract

Characterization of the groundwater flow system is one of the important processes for safety assessment of a radwaste repository, and it can be conceptualized and materialized by groundwater flow modeling. Since a radwaste repository is mostly likely to be located in a fractured rock aquifer, we reviewed the mathematical approaches to describe the groundwater flow in a fractured rock aquifer, and several modeling cases of nuclear advanced nations for safety assessment of their real or hypothetical radwaste repository, which can be used in making the R&D items in the related field.

방사성폐기물 처분장의 안전성 평가에 있어 지하수 유동 특성 평가는 매우 중요하며 이는 지하수 유동 모델링을 통해 개념화되고 구체화될 수 있다. 방사성폐기물 처분장은 심부 단열 암반 대수층에 건설될 확률이 높으며, 이에 본 논문에서는 단열 암반 대수층에서의 지하수 유동 모델링을 대상으로 해외 연구 동향을 검토하고 향후 국내 연구개발의 진행방향을 모색하고자 하였다.
