Description

Based on the principle of radiation protection, we studied the handling and emplacement procedure of waste and buffer material. We showed the handling flow diagram, conceptual drawings of handling and emplacement facility in two cases of emplacement; vertical emplacement in pit and horizontal emplacement in tunnel. The procedure and material for backfilling and plugging have been studied and the optimum method of current technologies is selected. Regarding the tunnel supporting, the removal of concrete supporting mainly was studied. Finally, we showed our view of monitoring before and after the close of disposal facility. (author)
