Uranium hydrogeochemical and stream sediment reconnaissance of the Iliamna NTMS quadrangle, Alaska (open access)

Uranium hydrogeochemical and stream sediment reconnaissance of the Iliamna NTMS quadrangle, Alaska

Presented are results of a hydrogeochemical and stream sediment reconnaissance (HSSR) of the Iliamna NTMS quadrangle, Alaska. In addition to this abbreviated data release, more complete data are available to the public in machine-readable form. In this data release are location data, field analyses, and laboratory analyses of several different sample media. For the sake of brevity, many field site observations have not been included in this volume. These data are, however, available on the magnetic tape. Appendices A to D describe the sample media and summarize the analytical results for each medium. The data were subsetted by one of the Los Alamos National Laboratory (LANL) sorting programs into groups of stream sediment, lake sediment, stream water, lake water, and ground water samples. For each group which contains a sufficient number of observations, statistical tables, tables of raw data, and 1:1000000 scale maps of pertinent elements have been included in this report.

Kriging analysis of uranium concentrations in Test Area C-74L, Eglin Air Force Base, Florida. [Neutrons]

Soil samples from Test Area C-74L, Eglin Air Force Base, Florida, were analyzed for depleted uranium by instrumental epithermal neutron activation analysis. The sampling design used was a modified polar coordinate scheme. The resulting data were analyzed with a statistical procedure called kriging to obtain a contour map of concentration and a 95% confidence interval map. The majority of uranium remains in the center of the area near the target abutment.

Examinations of samples of Bell Canyon Test 1-FF grout (open access)

Examinations of samples of Bell Canyon Test 1-FF grout

Portland cement grout identified as BCT-1-FF (Bell Canyon Test 1-FF) was used in borehole plugging experiments of the Bell Canyon Tests in Holl AEC-7 at the Waste Isolation Pilot Plant site in New Mexico during September 1979 and February 1980. This grout was made with fresh water. A study of this grout was begun in August 1979 in the laboratory to evauate the possible effects of temperature, pressure, and storage in fresh water or simulated groundwater (brine) on its phase composition and compressive strength at early ages. Phase composition was determined by X-ray diffraction. Temperatures ranged up to about 150/sup 0/F and included elevation at a few hours age after mixing; pressure was as high as 1500 psi; specimens were stored in simulated groundwater (brine) or in fresh water. Data from 1 to 90 days showed: (a) Higher temperature accelerated early strength gain. These differences essentially vanished by 90 days age. (b) Hydration products as identified by X-ray diffraction were normal; this indicated that a temperature range of 78 to 153/sup 0/F was not significant. (c) Pressure did not affect composition. (d) Storage in simulated groundwater (brine) or fresh water had no detectable effect. (e) Since the BCT-1-FF grout mixture …

Natural repository analouge program. Progress report, January 1-March 31, 1981

Samples from Oklo Reactor zone-9 (ORZ-9) have been analyzed for the isotopic abundances of Nd, Ce, Ru, and Mo. Interpretation of the Nd data has begun as part of the effort to reconstruct the operating parameters of the reactor. The study of ORZ-9 and the peripheral rocks is being enhanced by additional analytical capabilities. A procedure was developed to measure uranium isotopic ratios with high precision. This new method was used for the analysis of rocks peripheral to ORZ-9. Two rocks containing relatively small quantities of uranium were depleted in /sup 235/U. The result demonstrates that small quantities of uranium were removed from the reactor zone and redistributed over distances of several tens of meters. Procedures are being designed to make high precision measurements of the relative abundances of barium isotopes. They will be used as part of a study of the transport of alkali and alkaline earth elements at Oklo. Samples from distances up to 300 meters from the known mineralized area at Oklo have been selected and prepared in an effort to identify element transport paths over longer distances. A sample from the Athabasca sandstone, overlying the uranium ores at Key Lake, and another from the transition zone …

Assessment of criticality safety in DOE facilities (open access)

Assessment of criticality safety in DOE facilities

A study was made to assess nuclear criticality safety in DOE Facilities and to assess the effects of various types of possible improvements. The accident statistics in DOE operations show that the fatalities caused by Nuclear Criticality accidents are small compared to other accident categories. The data show the safety performance after 1965, compared to prior years, was considerably improved indicating that overall safety programs have been effective. Data on criticality safety violations were collected from eight major facilities. These data were categorized by severity indexes and causes were assigned. A total of 421 violations were used in the data base for analysis in a fault tree model. Calculations were made using the fault tree methodology to show expected improvement in safety (reduction in probability of a criticality accident) for a fixed reduction in the number of criticality violations. Based on this analysis, about equal emphasis should be placed on reducing mechanical failures and operator errors as efforts in these two areas will likely produce the most significant improvements in safety. A criticality safety infraction form was prepared to facilitate uniformity in recording data on infractions for subsequent analysis. Discussions with Nuclear Safety Specialists working in the field instilled confidence …

Stability of higher-order longitudinal modes in a bunched beam without mode coupling (open access)

Stability of higher-order longitudinal modes in a bunched beam without mode coupling

The theory of longitudinal instabilities of bunched beams was proposed by F. Sacherer. Starting from the Vlasov equation, he derived the integral equation for the perturbed distribution function. While the general method to solve the integral equation was given by Sacherer, a number of other papers discussing longitudinal bunched beam instability have also been published. Here we want to propose another formalism with which we can treat the integral equation without mode coupling for the case of a Gaussian bunch. We then generalize the formalism for the other bunch distributions, and derive a practical method to analyze the instability for the case of a parabolic bunch. While the solution of the Sacherer equation that we find is not new, we present another approach to solve it. Since the integral equation for the transverse instability is similar to that for the longitudinal instability, this formalism is also useful for the transverse case. 12 figs., 4 figs.

Methane drainage with horizontal boreholes in advance of longwall mining: an analysis. Final report (open access)

Methane drainage with horizontal boreholes in advance of longwall mining: an analysis. Final report

The US Department of Energy (DOE) Morgantown Energy Technology Center has implemented a comprehensive program to demonstrate the technical and economic viability of coalbed methane as an energy resource. The program is directed toward solution of technical and institutional problems impeding the recovery and use of large quantities of methane contained in the nation's minable and unminable coalbeds. Conducted in direct support of the DOE Methane Recovery from Coalbeds Project, this study analyzes the economic aspects of a horizontal borehole methane recovery system integrated as part of a longwall mine operation. It establishes relationships between methane selling price and annual mine production, methane production rate, and the methane drainage system capital investment. Results are encouraging, indicating that an annual coal production increase of approximately eight percent would offset all associated drainage costs over the range of methane production rates and capital investments considered.

Effect of vibrations on the density of loose-fill insulations (open access)

Effect of vibrations on the density of loose-fill insulations

Testing results of the three major loose-fill insulation products marketed in this country subjected to a variety of vibrations and impacts in a laboratory setting to determine the magnitude of the resultant density increases, are presented. Results show repeated drops of 19 mm (.75 inch) and 152 mm (6 inch) produced density increases of up to 75% for fiberglass, 45% for rock wool, and 27% for cellulosic materials. The three insulation products were also subjected to vibrations ranging from 0.1 mm (.004 inch) to 6.35 mm (.25 inch) to obtain ratios of final density over initial density. Under the test conditions studied it was observed that the lighter materials settled more percentagewise than the dense materials.

1170-MW(t) HTGR-PS/C plant application study report: shale oil recovery application

The US has large shale oil energy resources, and many companies have undertaken considerable effort to develop economical means to extract this oil within environmental constraints. The recoverable shale oil reserves in the US amount to 160 x 10/sup 9/ m/sup 3/ (1000 x 10/sup 9/ bbl) and are second in quantity only to coal. This report summarizes a study to apply an 1170-MW(t) high-temperature gas-cooled reactor - process steam/cogeneration (HTGR-PS/C) to a shale oil recovery process. Since the highest potential shale oil reserves lie in th Piceance Basin of Western Colorado, the study centers on exploiting shale oil in this region.

Chemical-equilibrium calculations for aqueous geothermal brines (open access)

Chemical-equilibrium calculations for aqueous geothermal brines

Results from four chemical-equilibrium computer programs, REDEQL.EPAK, GEOCHEM, WATEQF, and SENECA2, have been compared with experimental solubility data for some simple systems of interest with geothermal brines. Seven test cases involving solubilities of CaCO/sub 3/, amorphous SiO/sub 2/, CaSO/sub 4/, and BaSO/sub 4/ at various temperatures from 25 to 300/sup 0/C and in NaCl or HCl solutions of 0 to 4 molal have been examined. Significant differences between calculated results and experimental data occurred in some cases. These differences were traced to inaccuracies in free-energy or equilibrium-constant data and in activity coefficients used by the programs. Although currently available chemical-equilibrium programs can give reasonable results for these calculations, considerable care must be taken in the selection of free-energy data and methods of calculating activity coefficients.

Asphalt emulsion sealing of uranium mill tailings. 1980 annual report (open access)

Asphalt emulsion sealing of uranium mill tailings. 1980 annual report

Studies of asphalt emulsion sealants conducted by the Pacific Northwest Laboratory have demonstrated that the sealants are effective in containing radon and other potentially hazardous material within uranium tailings. The laboratory and field studies have further demonstrated that radon exhalation from uranium tailings piles can be reduced by greater than 99% to near background levels. Field tests at the tailings pile in Grand Junction, Colorado, confirmed that an 8-cm admix seal containing 22 wt% asphalt could be effectively applied with a cold-mix paver. Other techniques were successfully tested, including a soil stabilizer and a hot, rubberized asphalt seal that was applied with a distributor truck. After the seals were applied and compacted, overburden was applied over the seal to protect the seal from ultraviolet degradation.

Physics of two-phase flow: choked flow (open access)

Physics of two-phase flow: choked flow

It is shown that the basic equations governing the flow of a two-phase fluid, i.e., liquid and vapor, are natural extensions of those equations that describe single-phase flow. The exact form of the equations depends on the particular assumptions used to characterize the two-phase flow, i.e., the equations depend on the model chosen. In general the mathematical model is selected so as to retain as much of the physics of the phenomena as possible while at the same time permitting solutions to be obtained without undue complexity. The following quantities were computed for saturated water substance over the temperature range 100 to 250/sup 0/C and for saturated Refrigerant -114 over the range -20 to +70/sup 0/C: choking velocity, critical or choking flow density, and saturation properties. Tables of the results are given along with graphs of selected functions.

Quantitative analysis of the economically recoverable resource (open access)

Quantitative analysis of the economically recoverable resource

The objective of this study is to obtain estimates of the economically recoverable gas in the Appalachian Basin. The estimates were obtained in terms of a probability distribution, which quantifies the inherent uncertainty associated with estimates where geologic and production uncertainties prevail. It is established that well productivity on a county and regional basis is lognormally distributed, and the total recoverable gas is Normally distributed. The expected (mean), total economically recoverable gas is 20.2 trillion cubic feet (TCF) with a standard deviation of 1.6 TCF, conditional on the use of shooting technology on 160-acre well-spacing. From properties of the Normal distribution, it is seen that a 95 percent probability exists for the total recoverable gas to lie between 17.06 and 23.34 TCF. The estimates are sensitive to well spacings and the technology applied to a particular geologic environment. It is observed that with smaller well spacings - for example, at 80 acres - the estimate is substantially increased, and that advanced technology, such as foam fracturing, has the potential of significantly increasing gas recovery. However, the threshold and optimum conditions governing advanced exploitation technology, based on well spacing and other parameters, were not analyzed in this study. Their technological impact …

Information and the solar consumer

A brief review of the use of solar energy in the US is presented and then the attitude of solar consumer are summarized. Results of research show that information or knowledge of an innovation proceeds at a faster rate than the actual adoption of that innovation. It is noted that until the level of solar knowledge increases to about 30% of the potential end users who have seriously considered the technology and plan to invest in it, adoption of the technology will be limited.
