방사성폐기물 처분에서 미생물의 역할과 중요성

Roles and Importance of Microbes in the Radioactive Waste Disposal

백민훈, 이승엽, 노열

Abstract

Recently the importance and interest for the microbes has been increased because several important resultsfor the effects of microbes on the radioactive waste disposal have been published continuously. In this study,research status and major results on the various roles and effects of microbes in the radioactive waste disposalhave been investigated. We investigated and summarized the roles and major results of microbes in a multi-barrier system consisting of an engineered barrier and a natural barrier which is considered in radioactive wastedisposal systems. For the engineered barrier, we discussed about the effects of microbes on the corrosion of awaste container and investigated the survival possibility and roles of microbes in a compacted bentonite buffer.For the natural barrier, the roles of microbes present in groundwaters and rocks were discussed and summarizedwith major results from natural analogue studies. Furthermore, we investigated and summarized the roles andvarious interactions processes of microbes and their effects on the radionuclide migration and retardationincluding recent research status. Therefore, it is expected that the effects and roles of microbes on theradioactive waste disposal can be rigorously evaluated if further researches are carried out for a long-termbehavior of the disposal system in the deep geological environments and for the effects of microbes on theradionuclide migration through geological media.

Key Words : 미생물, 미생물의 역할 및 영향, 방사성폐기물, 처분시스템, 핵종이동 및 지연, Microbes, Roles and Effects of Microbes, Radioactive Waste, Disposal System, RadionuclideMigration and Retardation.
