The pneumatic capsule pipeline transportation is a method to transport various materials by utilizing differential pneumatic pressure. It has advantages over conventional methods (e.g., vertical transport using a lift in a shaft) in terms of safety and economical efficiency when it is applied to the deep radioactive waste disposal facilities (Hane, et al., 2002). In this paper, focusing attention on the safety and efficiency of transportation, we propose a concept of the comprehensive transportation system for the high-level radioactive wastes disposal facilities. By introducing a curved pipe section to the pipeline system, we show the applicability and practicability of the system for the facility by analytical study.
