Calorimetric assay of reactor grade PuO{sub 2}

Description: This paper describes an experiment to estimate random and systematic errors in determining the effective specific power of plutonium. Precisons and accuracies comparable to coulometric assay were demonstrated for a wide range of plutonium isotopic compositions. Thus, calorimetric assay can provide an effective method for plutonium assay of materials in the nuclear fuel cycle.

Continuous Czochralski growth. Silicon sheet growth development of the large area silicon sheet task of the Low Cost Silicon Solar Array Project. First quarterly progress report, October--December 1977

Description: The development of equipment and processes to produce single crystal solar silicon by a continuous Czochralski method was studied. ''Continuous'' is defined as the ability to produce 100 kilograms of crystal from only one melt container. The equipment to be used is a Hamco CG2000 Production Crystal Grower. Certain modifications will be made to the grower to enable periodic replenishment of silicon into the crucible and removal of grown crystals. The crystal grower was constructed and installed in a separate room designated and prepared for the project. It was adapted with a modified throat, a vacuum-tight isolation valve, an enlarged pull chamber to hold a supply of poly material, and a modified automatic diameter control (ADC) optical system. It was fully tested and made ready for trial runs. Designs are under way for other modifications to the equipment, including a recharge system, a polysilicon attachment device, and a modified bead-chain pull mechanism capable of pulling and simultaneously weighing a 30 to 40 Kg growing crystal. An economic model was developed for batch CZ as a base-line reference, and for two methods of continuous CZ. Preliminary analysis indicates a cost (value added by crystal growth) of approximately $13 to $17 per kilogram of usable crystal for continuous CZ versus $33.00 for state of art methods. This model will be updated as additional data, process parameters and equipment requirements are obtained.

Energy consumption in the pipeline industry

Description: Estimates are developed of the energy consumption and energy intensity (EI) of five categories of U.S. pipeline industries: natural gas, crude oil, petroleum products, coal slurry, and water. For comparability with other transportation modes, it is desirable to calculate EI in Btu/Ton-Mile, and this is done, although the necessary unit conversions introduce additional uncertainties. Since water and sewer lines operate by lift and gravity, a comparable EI is not definable.

Energy study of pipeline transportation systems. Executive summary. Final report

Description: The basic objectives of the overall study were to (1) characterize the pipeline industry and understand its energy consumption in each of the five major pipeline-industry segments: gas, oil, slurry, fresh water, and waste water; (2) identify opportunities for energy conservation in the pipeline industry, and to recommend the necessary R, D, and D programs to exploit those opportunities; (3) characterize and understand the influence of the Federal government on introduction of energy conservative innovations into the pipeline industry; and (4) assess the future potential of the pipeline industry for growth and for contribution to the national goal of energy conservation. This project final report is an executive summary presenting the results from the seven task reports.

Energy study of pipeline transportation systems. Executive summary. Final report

Description: The basic objectives of the study were to: characterize the pipeline industry and understand its energy consumption, i.e., the patterns of consumption and the quantities and intensities of that consumption in each of the five major pipeline industry segments: gas, oil, slurry, fresh water, and waste water; characterize and understand the influence of the Federal Government on the introduction of energy-conservative innovations into the pipeline industry; identify opportunities for energy conservation in the pipeline industry, and to recommend the necessary programs of research, development, and demonstration to exploit those opportunities; and assess the future potential of the pipeline industry for growth and for contribution to the national goal of energy conservation, including consideration of freight pipelines. Pipelines for crude oil, natural gas, petroleum products, water, coal slurries, and for the pneumatic transport of solids are considered. Information is included on: energy consumption for pipeline transport; energy efficient pumping equipment; methods for reducing drag in pipelines; government regulations related to pipelines; environmental aspects of pipeline transport; and the economic outlook and growth of the pipeline industry.

Geologic investigation of the Virgin River Valley salt deposits, Clark County, southeastern Nevada, to investigate their suitability for possible storage of radioactive waste material as of September 1977

Description: The results from a geologic investigation of the Virgin River Valley salt deposits, Clark County, southeastern Nevada, to examine their suitability for further study and consideration in connection with the possible storage of radioactive waste material are given. The results indicate that (1) approximately one-half of the salt body underlies the Overton Arm of Lake Mead and that the dry land portion of the salt body that has a thickness of 1,000 feet or more covers an area of about four and one-half square miles; (2) current tectonic activity in the area of the salt deposits is believed to be confined to seismic events associated with crustal adjustments following the filling of Lake Mead; (3) detailed information on the hydrology of the salt deposit area is not available at present but it is reported that a groundwater study by the U.S. Geological Survey is now in progress; (4) there is no evidence of exploitable minerals in the salt deposit area other than evaporites such as salt, gypsum, and possibly sand and gravel; (5) the salt deposit area is located inside the Lake Mead Recreation Area, outlined on the accompanying Location Plat, and several Federal, State, and Local agencies share regulatory responsibilities for the activities in the area; (6) other salt deposit areas of Arizona and Nevada, such as the Detrital Valley, Red Lake Dome, Luke Dome, and Mormon Mesa area, and several playa lake areas of central Nevada may merit further study; and (7) additional information, as outlined, is needed to more thoroughly evaluate the salt deposits of the Virgin River Valley and other areas referred to above.

Investigation of the seismicity at regional and teleseismic distances following underground nuclear detonations. Final technical report

Description: The main emphasis of the investigation was to determine the seismicity of the Nevada Test Site area during a time period which encompassed a lull in the testing program. The time period studied extends from April 1, 1973 to October 1, 1975. The aftershock sequence of nuclear shots fired on Pahute Mesa during late 1975 and early 1976 were also included.

Measuring and Predicting the Dynamic Effects of a Confined Thin Metal Plate Pulse Heated Into the Liquid-Vapor Regime

Description: The dynamic response of a confined thin layer of lead heated rapidly and uniformly to a supercritical state was investigated. Lead targets 0.025 mm and 0.05 mm thick were contained between a thin titanium tamping layer and a thick layer of fused quartz with several different gap widths between the lead and the confining surfaces. After being heated by an electron beam for about 50 ns, lead specimens expanded to a state of approximately half liquid and half vapor. Measurements of the stress in the quartz and the velocity of the tamper produced by the expanding lead were compared with one dimensional hydrodynamic computer program predictions. Measured and predicted peak stresses in the quartz for no gaps were approximately 12 kilobars and agreed within one kilobar. Peak stresses decreased rapidly with gap size to values, at 0.02 mm gaps, of about one kilobar for the 0.025 mm lead targets and five kilobars for the 0.05 mm targets. These values were confirmed by measurements. Predictions and measurements of tamper velocity (momentum) were within 10% only when the lead and confining walls were in close contact. The observed velocities for even very small gaps were substantially below predictions. These differences are attributed primarily to separation of the liquid and vapor phases during the expansion.
