R&D project on remote handling and emplacement techniques for waste package and buffer material at high-level radioactive waste repository, conducted by RWMC(Radioactive Waste Management Funding and Research Center), had started at fiscal year 2000. Several investigation and performance-tests on repository operation technologies are now on the process to be summarized their technical feasibility, applicability and achieved performance as a technical menu. A pre-assembled package method of engineered barrier system(EBS), which consists of waste package itself and buffer material, was evaluated as a type of remote operation concept which can realize a relatively streamlined operation method inside a drift tunnel at a deep underground repository. Performance of air-bearing unit for the transportation of pre-assembled package was tested under simulated drift surface condition, especially for surface unevenness and surface preparation of the drift. Applicability and flexibility of emplacement operation for the pre-assembled package by use of the air-bearing unit was discussed.
