Abstract

The world's first underground repository for low- and intermediate- level radioactive waste (SFR1) has been in operation since 1988. SFR1 can accommodate $1,000m^3$ of radioactive waste per year with 4 chambers and 1 silo with a total capacity of $63,000m^3$ of radioactive waste. With extended operation time of 10 of the 12 nuclear power reactors and dismantling of the other 2 nuclear reactors, more nuclear waste need to be disposed in the future. Therefore, Swedish Nuclear Fuel and Waste Management Company (SKB) submitted a license application for a repository extension (SFR3) that consists of 6 additional rock chambers with a capacity of $108,000m^3$ of radioactive waste and for accommodating 9 boiling water reactor tanks. In this study, plans for the extension SFR3 are presented with the geological, geomechanical and hydrogeological issues to be considered.

스웨덴 포쉬마크 (Forsmark)지역에서는 1988년부터 세계 최초의 동굴식 중저준위 방사성 폐기물 처분장(SFR1)이 운영되고 있다. 4개의 터널 및 1개의 사일로에 용량 $63,000m^3$의 처분공간이 확보되어 연간 $1,000m^3$의 폐기물을 처분할 수 있었지만, 스웨덴 내 12기 중 10기의 원자로의 수명이 연장되고, 나머지 2기의 원자로가 폐쇄되어 추가 폐기물 처분에 대한 요구가 발생하게 되었다. 따라서 6기의 수평터널을 추가로 건설하여 폐기물과 9개의 반응로 용기 처분을 위한 $108,000m^3$의 처분 공간을 확보할 계획으로 스웨덴 방사성폐기물 관리주식회사(SKB)는 SFR3으로의 확장을 위한 허가 신청서를 2014년 정부에 제출하였다. 본 연구에서는 SFR3의 추가 확장 계획에 대해 소개하고, SFR3의 계획 시에 고려된 지질학적, 암반공학 및 암반수리학적인 요소들을 소개하였다.
