Abstract

The worldwide Status-of-Art survey for the in-situ experiments of the engineered barrier system for HLW underground disposal was performed as a preliminary action for the design of the in-situ demonstration at KURT. Some nations, which have executed or is ongoing the in-situ experiments at their underground research facilities, were summarized in this review. The demonstration projects reviewed were TBT/Sweden-France, LOT/Sweden, HE-E/Switzerland, PRACLAY/Belgium, FEBEX/Spain, HORONOBE/Japan, and BCE/Canada. The investigated items for the projects were mainly their purposes, constitutional structures, test conditions, monitoring parameters and the measuring tools, and test results. In this review, the hardware design and the assembling of the test system were more concentrated rather than their experimental results, because the purpose of this review is to achieve the necessary information for the practical design of the in-situ experiment to be installed at KURT. A mid scale in-situ demonstration of EBS at KURT, that is called IN-DBES, will be launched right after the completion the expanding project of KURT in 2015. It is hoped that the structural design, installing methods, hardware equipments required in the establishment of IN-DEBS will be referred on this review.

본 연구에서는 한국원자력연구원 부지 내 KURT 연구시설에 심지층 처분실증시험을 수행할 목적으로 사전 해외현황조사를 실시하였다. 고준위폐기물 심지층 처분을 목적으로 지하연구시설을 구축한 나라들을 대상으로 현재 수행되었거나, 수행이 진행 중인 공학적방벽 성능평가 시험들을 조사하였다. 주요 실증시험으로는, 스웨덴/프랑스 TBT, 스웨덴 LOT, 스위스 HEE, 벨기에 PRACLAY, 스페인 FEBEX, 일본 HORONOBE, 및 캐나다 BCE 등이었다. 각 실증시험에 대하여 시험의 목적, 시험체의 구성, 시험조건, 세부 구성도, 측정 항목, 측정기기, 및 도출된 결과 등을 구체적으로 조사하였으며, 시험결과보다는 시험목적 및 시험물의 구축방법 파악에 더 집중하였다. 왜냐하면, 각국의 공학적방벽 성능시험방법의 검토를 통해 향후 KURT에서 추진하게 될 공학적방벽 실증시설의 설계에 도움을 얻고, 다양한 성능시험을 동시에 수행할 수 있도록 하기 위해서였다. 향후 KURT 확장을 통해 공학적방벽 성능시험 터널을 확보하고, 중규모의 성능 시험시연을 추진하게 될 예정이다. 본 기술검토를 통해 이 때 추진할 시험내역과 시험체의 구성 및 크기 등의 상세 설계에 필요한 기초적인 지식을 얻고자 하였다.
