Abstract

In this case study, detailed survey of the Excavation Damaged Zone (EDZ) evaluation for the deep geological repository for high level nuclear waste was conducted. Oversea and Domestic case studies were compiled and investigated. EDZ is considered a crucial factor in the performance assessment of spent fuel disposal, leading to numerous studies worldwide aiming to understand the characteristics of the EDZ and quantitatively assessment of its extent through field and laboratory tests at Underground Research Laboratory (URL) sites. To enhance the understanding of EDZ, this study begins with defining and exploring the history of EDZ, compiling factors influencing EDZ, and summarizing the impacts caused by EDZ. Subsequently, an analysis of EDZ and rock properties is performed, followed by presenting generalized outcomes, limitations drawn from previous research, and proposing future research directions.

본 사례연구에서는 사용후핵연료 처분장 건설을 위한 굴착손상영역(EDZ) 평가 및 국내외 실증연구사례를 정리하고 조사하였다. 굴착손상영역은 사용후핵연료 처분장의 성능평가에 중요한 요소로 간주되며, 국내외 여러 국가에서 지하 연구시설 현장 및 실험실 시험을 통해 굴착손상영역의 특성 파악 및 그 범위를 정량적으로 판단하고자 하는 연구들이 수행되어왔다. 굴착손상영역에 대한 이해를 위하여 굴착손상영역의 정의, 역사를 시작으로 굴착손상영역에 영향을 주는 요인과 굴착손상영역으로 인한 영향을 정리하였다. 다음으로 굴착손상영역과 암반 특성에 관한 분석을 수행하였으며, 선행연구를 통해 도출한 일반화된 요약과 한계점, 향후 연구 방향을 제시하였다.
