Preliminary Study of the Feasibility of Underground Pressurized Containers

摘要

A study of a concept for fuel storage containers for protective shelters is reported. It involves the use of a flexible tank together with internal pressurization for improving the resistance to high overpressure loading. The objective of the study was to form a judgment on the practicability of expending further effort on developing methodologies for designing pressurized fuel tanks. To permit forming a valid judgement, a study was made which included a literature survey, a preliminary design of a tank, and an evaluation of the cost of fabrication, erection, and placement of the tank. The tank considered consisted of two 15-ft radius hemispherical heads enclosing a cylindrical section of 30-ft length and 2-in thickness. The peak value of the dynamic overpressure which was considered was 1,000 psi. The tank was analyzed to determine its deformation, stability and cost characteristics and to determine the amount of internal pressure necessary to preclude buckling. (Author)
