Static and Dynamic Tests of Model Pressurized Underground Fuel Storage Containers.
Abstract
Static and dynamic tests were performed on four model steel tanks in an experimental program designed to provide data on the behavior of buried fuel storage containers under high overpressures associated with nuclear air blast. The model tanks were fabricated from 24-gage T-304 stainless steel sheets. Each model consisted of two 12-inch-long cylindrical sections with 12-inch-diameter hemispherical end caps. The models were partially filled with silicone fluid, used to simulate the effects of liquid fuel. Internal pressures of 100 psi were applied to the tanks prior to external test loading; this pretensioned the tank shell to resist the compressive effects of external loading. External static pressures up to 500 psi and dynamic pressures up to 250 psi were developed in the 4-foot-diameter, small-blast-load generator at the waterways Experiment Station, where the test was conducted. As a result of the test program it was found that internal pressurization significantly improved the blast-resistance properties of buried steel tanks. The tests provided data which were used to establish design criteria for the prototype structures. Data from the experiment were also compared with analytical results calculated by finite element computer code to verify the analytical model and computational techniques. The experimental data compared favorably with the analytical results. (Author)
