Abstract

This paper presents the status and experiences of Low and Intermediate-level radioactive Waste(LILW) disposal facility in Korea. The LILW disposal facility of 800,000 drums (200 L/drum) is being constructed in the site of KORAD's LILW Disposal Center(206 m², Gyeongju-si). The first stage of the LILW facility construction was completed in June 2014, and approved for use by Nuclear Safety and Security Commission (NSSC) in December 2014. The first stage of the LILW facility is a type of underground silo with disposal capacity of 35,200 m³ (100,000 drums). The second stage of the LILW facility is under construction to be completed by December 2020. Site construction is currently underway. The second stage of the LILW facility is a type of near-surface disposal with disposal capacity of 32,875 m³ (125,000 drums)

이 논문에서는 한국의 중·저준위 방사성폐기물(이하 방폐물) 처분시설의 건설과 시공사례 등을 제시하였다. 현재 경주시 소재 한국원자력환경공단의 환경관리센터 부지 약 206만 m²에서 총 80만 드럼(드럼 당 200 L) 규모의 중·저준위 방폐물 처분시설 건설사업이 진행되고 있다. 1단계 동굴처분시설은 2014년 6월에 건설이 완료되었으며, 원자력안전위원회로부터 같은 해 12월에 사용승인을 받았다. 1단계 동굴처분시설은 지하에 사일로를 건설하는 방식이며, 처분용량은 35,200 m³으로 총 10만 드럼의 방폐물을 처분할 수 있다. 2단계 표층처분시설은 현재(2017.6) 부지정지공사를 진행 중으로, 2020년 12월 준공 될 예정이다. 2단계 표층처분시설은 지표면에 콘크리트 구조물을 건설하여 방폐물을 처분하는 방식이며, 처분용량은 32,875 m³으로 총 12.5만 드럼의 방폐물을 처분할 수 있다.
