A reinforced-concrete dual-purpose underground parking garage and personnel sheiter designed for a long-duration incident pressure of 40 psi was tested. The sheiter was exposed to shot Priscilla, an approximately 37-kt 700-ft balloon burst (June 24, 1957), at a ground range of 1600 ft (predicted 35-psi peak incident-pressure level). The recorded peak incident pressure at the shelter was approximately 39 psi. Postshot soil borings were made to obtain undisturbed samples for determining soil characteristics. Preshot and postshot field surveys were made to determine the total lateral and vertical displacement of the structure. The test structure provided adequate protection from the effects of the test device at the test GZ distance. Despite failure of the door sealing gasket, a rise in pressure in the interior did not exceed 1.0 psi. The flat-slab roof and supporting structure were more than adequate to resist the 39psi peak incident test loading. (P.C.H.).

The objective of Project 30.7 was to investigate the predicted behavior of German underground personnel shelters, equipment, and certain instrumentation. Data obtained will be used for evaluation and improvement of present design criteria. Nine reinforced-concrete underground shelters, designed by German engineers, were tested at the 170-, 155-, 110-, 78-, 26-, 11.5-, and 7.2-psi overpressure ranges as determined from average blast-line instrumentation measurements.

Project 30.2 was conducted to test a reinforced-concrete dual-purpose underground parking garage and personnel shelter designed for a long-duration incident pressure of 40 psi. The shelter was exposed to shot Priscilla, an approximately 37-kt 700-ft balloon burst (June 24, 1957), at a ground range of 1600 ft (predicted 35-psi peak incident-pressure level). The recorded peak incident pressure at the shelter was approximately 39 psi. Postshot soil boring were made to obtain undisturbed samples for determining soil characteristics. Preshot and postshot field surveys were made to determine the total lateral and vertical displacement of the structure. Blast instrumentation consited of Wiancko pressure gauges, Carlson earth-pressure gauges, dynamic-pressure gauges, and a self-recording pressure gauge. Structural response was recorded by Ballistic Research Laboratories deflection gauges. Radiation measurements were taken using film dosimeters, gamma-radiation chemical dosimeters, and one gamma-rate telemetering unit. (Author).

The objective of Part I of Project 39.3 was to measure transient air temperatures at selected locations in the blast-biology underground shelter in Area 1 for shot Galileo, Operation Plumbbob. The objective of Part II of Project 39.3 was to evaluate thermal burns from a nuclear explosion on biological receivers in a shelter. Eight Chester White pigs were used as test animals. One pig in the entrance and one about 3 ft inside the door received severe burns. These burns were carbonized on the surface and caused transepidermal damage with up to 0.3 mm penetration into the dermis. Animals away from the entrance and those in the slow fill side received no burns. The possible sources of this damaging thermal energy are discussed.
