In response to the regulatory requirement, "After comparing and examining multiple design options for engineered barriers, formulate a design that is superior in performance to suppress the movement of radioactive materials," the cost-effectiveness of the exposure dose and the project cost is shown in the attached sheet. The selection procedure used is presented. In this paper, preliminary dose assessment was attempted to contribute to the cost-effectiveness.
