초록
Co-60은 원자력발전소에서 발생하는 부식생성물로서 중저준위 방사성폐기물에 함유된 가장 중요한 핵종중 하나다 방사성폐기물처분장 충전물로 많이 사용되는 점토층을 통한 Co-60 확산실험을 하여 밀도변화에 따른 확산계수를 구하였다. Co-60의 확산실험 기간은 점토 밀도에 따라 최소 9시간에서 최대 120일이 걸렸으며, 확산계수는 저밀도인
Diffusivity of ions of radioactive species is an important factor for designing radwaste repositories. Clay minerals are used as a backfill material. In this study, diffusion of Co-60 ions through the bentonite having various densities has been studied, using a diffusion cell. The measured diffusivities of Co-60 ions decreased as the density of bentonite increased. The diffusivity of Co-60 ion decreased from
