초록

열-수리-역학-화학적 복합거동의 영향은 고준위방사성폐기물 심층 처분시스템의 성능평가 및 안전성 평가 측면에서 중요하기 때문에 이를 분석하고 예측하기 위한 해석모델과 수치해석 기법이 필요하다. 하지만, 장기간에 걸쳐 발생하는 열-수리-역학-화학적 복합거동에 관련된 다양한 현상들이 비선형적 거동을 보이고 그 구성방정식들의 상관관계가 명확하지 않기 때문에 이를 정확하게 해석하고 예측할 수 있는 수치모델과 모델링 기법을 개발하는 것은 매우 어렵다. 뿐만 아니라, 개발된 수치모델과 모델링 기법을 검증하기 위해서는 오랜 시간동안 수행되어야 하는 고비용의 실험실 시험과 현장시험이 필요하기 때문에 열-수리-역학-화학적 복합거동 분석과 예측을 위한 수치모델과 모델링 기법의 개발뿐만이 아니라 검증 역시 쉽지 않다. 이러한 문제를 해결하여 효과적인 수치모델 및 해석기법 개발과 실험실 시험 및 현장시험 데이터를 활용한 검증을 수행하기 위해 국제공동연구 DECOVALEX(DEvelopment of COupled models and their VALidation against EXperiment) 프로젝트가 1992년부터 시작되었다. 한국의 경우, 한국원자력연구원이 2008년부터 DECOVALEX-2011, DECOVALEX-2015, 그리고 DECOVALEX-2019에 참여하였다. 본 기술 보고에서는 지난 3단계의 DECOVALEX 프로젝트에서 수행된 모든 과제의 주요 내용을 국내 암반 및 지반공학자들에게 소개하였다.

An effect of coupled thermo-hydro-mechanical and chemical (THMC) behavior is an essential part of the performance and safety assessment of geological disposal systems for high-level radioactive waste and spent nuclear fuel. Furthermore, numerical models and modeling techniques are necessary to analyze and predict the coupled THMC behavior in the disposal systems. However, phenomena associated with the coupled THMC behavior are nonlinear, and the constitutive relationships between them are not well known. Therefore, it is challenging to develop numerical models and modeling techniques to analyze and predict the coupled THMC behavior in the geological disposal systems. It is also difficult to verify and validate the development of the models and techniques because it requires expensive laboratory tests and in-situ experiments that need to be performed for a long time. DECOVALEX was initiated in 1992 to efficiently develop numerical models and modeling techniques and validate the developed models and techniques against the lab and in-situ experiments. In Korea, Korea Atomic Energy Research Institute has participated in DECOVALEX-2011, DECOVALEX-2015, and DECOVALEX-2019 since 2008. In this study, all tasks in the three DECOVALEX projects were introduced to the researcher in the field of rock mechanics and geotechnical engineering in Korea.
