Response of Dual-Purpose Reinforced-Concrete Mass Shelter

BS>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 c… more

Effects of Overpressures in Group Shelters on Animals and Dummies

S>Relative biological hazards of blast were studied in two types of communal air-raid shelters during Shots 1 and 8. Dogs, restrained within the shelters during detonation, were studied pathologically and clinically for blast injuries. Two anthropometric dummies were test objects for displacement studies utilizing high-speed photography. Physical data included pressure vs time and air-drag determinations. During Shot 1, animals sustained marked blast damages (hemorrhages in lungs and abdominal … more

Radiochemical Processing-Off-Site Transportation and Ultimate Storage Problems

Safe and economic methods of handling radioactive materials off-site are required for the successful operation of nuclear chemical plants. These occasions arise in the shipment of spent fuel, radioactive, isotopes, and liquid wastes. An unsolved problem exists in the development of techniques and sites for the final disposal of waste products. (auth)

TEST OF GERMAN UNDERGROUND PERSONNEL SHELTERS

The predicted behavior of German underground personnel shelters, equipment, and certain instrumentation was investigated. Data obtained will be used for evaluation and improvement of present design criteria. Nine reinforcedconcrete 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. Reinforcing steel, doors, and ventilation equipment were rece… more

F.C.D.A. Family Shelter Evaluation

In order to determine the effects of atomic explosions on small civil defense shelters for family use, 29 simple structures were built along an arc 1200 ft from the target point and exposed to Buster Bursts B, C, and D. The structures were of four basic types; covered-trench, metal-arch, wood-arch, and basement lean-to. Because of poor cohesive properties of the soil, much of the earth cover on the shelters was removed by the first shot. Since test procedures prevented restoration of structures… more

Evaluation of Buried Conduits as Personnel Shelters

Supersedes ITR-1421. Twelve large-diameter buried conduit sections of various shapes were tested in the 60- to l49-psi overpressure region of Burst Priscilla to make an empirical determination of the degree of personnel protection afforded by commercially available steel and concrete conduits at depths of burial of 5, 7.5, and 10 feet below grade. Essentially, it was desired to assure that Repartment of Defense Class I, 100psi and comparable radiations, and Class II, 50-psi and comparable radia… more

A global overview of risk management of the DOE complex

No endeavor is risk-fire and as we realize the inherent risks in society, our only viable solution is to manage the risk. Application of an integrated risk management program of a large technological system like the DOE complex is a difficult, task; but it is the only rational means to optimize the risk-benefit equation. An effective risk management culture-within the DOE complex will in the long run, ensure a consistent response to mitigate identified risks. An effective risk management progra… more

Environmental Measurement-While-Drilling system for real-time field screening of contaminants

Sampling during environmental drilling is essential to fully characterize the spatial distribution and migration of near surface contaminants. However, the analysis of these samples is not only expensive, but can take weeks or months when sent to an off-site laboratory. In contrast, measurement-while-drilling (MWD) screening capability could save money and valuable time by quickly distinguishing between contaminated and uncontaminated areas. Real-time measurements provided by a MVM system would… more

Contaminant Distributions at Typical U.S. Uranium Milling Facilities and Their Effect on Remedial Action Decisions

Past operations at uranium processing sites throughout the US have resulted in local contamination of soils and ground water by radionuclides, toxic metals, or both. Understanding the origin of contamination and how the constituents are distributed is a basic element for planning remedial action decisions. This report describes the radiological and nonradiological species found in ground water at a typical US uranium milling facility. The report will provide the audience with an understanding o… more

Assessment of unsaturated zone radionuclide contamination in the 200 areas of the Hanford site, Washington

The 200 East and 200 West Areas at the Department of Energy`s Hanford site in southeastern Washington, contain chemical and nuclear fuel processing facilities that disposed of large volumes of chemical and radionuclide effluents to the ground via various structures such as ponds, cribs and ditches. A geophysical logging investigation was implemented in 1992 to assess the nature and extent of contamination beneath select liquid disposal sites in the 200 Areas. The borehole geophysical logging wa… more

Safety assessment document: Gunite tank sludge removal

This document presents the assessment and analysis of the safety hazards involved in the Gunite Tank Sludge Removal Project. The six Gunite tanks comprising the South Tank Farm were constructed in 1943. Since then, one or more of these tanks have been used continuously for the temporary storage of intermediate level radioactive wastes (ILW) before evaporation. Another tank has been used for this temporary storage of the concentrated ILW prior to its disposal. Upon completion of the new ILW Syst… more

Remediation of uranium mill tailings by an integrated biological and chemical process

Dilute calcium chloride brine solution was found to be effective in the solubilization of toxic heavy metals and long half-life radionuclides (Th-230, Ra-226 and Pb-210) from uranium ores and mill tailings. The recovery of heavy metals and radionuclides from uranium mill tailing effluents was studied with calcium alginate beads. The maximum cadmium and zinc uptakes by calcium alginate beads were determined to be 2.8 {times} 10{sup {minus}3} and 2.3 {times} 10{sup {minus}3} mol/dry weight of alg… more

Parametric design using IGRIP

The Department of Energy`s (DOE) Hanford site near Richland, Washington is being cleaned up after 50 years of nuclear materials production. One of the most serious problems at the site is the waste stored in single-shell underground storage tanks. There are 149 of these tanks containing the spent fuel residue remaining after the fuel is dissolved in acid and the desired materials (primarily plutonium and uranium) are separated out. The tanks are upright cylinders 75 ft. in diameter with domed t… more

A survey of ecological risk assessment at DOE facilities

The US Department of Energy (DOE) Risk-Based Standards Working Group is studying standard-setting and remedial action based on realistic estimates of human health and ecological risks. Federal and state regulations require DOE to assess ecological risks due to present and past operation of DOE facilities and ecological damage caused by remedial actions. Unfortunately, little technical guidance has been provided by regulatory agencies about how these assessments should be performed or what const… more
