To appropriate deal the high-level radioactive waste with internationally recognized method, deep geological disposal repository with multibarrier system is being planned to construct in China. As one of the most important engineering barriers，the canister should maintain integrity and avoid any deformation to meet the safety functions of containing radioactive waste and isolating it from groundwater over the design lifetime. Therefore，it is crucial to reasonably design the shape and thickness of the canister. The properties of the canister materials are important factors affecting the shape and thickness design of the canister. Carbon steel is one of the candidate materials for high-level waste canister in China. Since Japan has chosen carbon steel as the canister material and has completed the trial production of the canister， this paper mainly systematically introduced the design concept about basic shape and thickness of the canister for high-level radioactive in Japan，and analyzed the key factors that need to be considered in the design of the shape and thickness for the canister. Also, emphasis was placed on the determination of the pressure thickness parameter and radiation shielding thickness parameter to provide guidance for the design of the canister for high-level radioactive in China.
