Relativistic Many-Body Bound Systems: Electromagnetic Properties

Report presenting the formulae for the calculation of the electron scattering form factors, and of the static magnetic dipole and electric quadrupole moments, of relativistic many-body bound systems. The framework, given in NBS Monograph 147, is relativistic quantum field theory in the Schrodinger picture ; the physical particles, i.e. the solutions of the interacting fields, are given as linear combinations of the solutions of the free fields, called the parton fields. The parton-photon interaction is taken as given by minimal coupling, p -> p - eA ; in addition the contribution of the photon-vector meson vertex of the vector dominance model is derived.

Fluidized-Bed Regeneration of Sulfated Dolomite from a Coal-Fired FBC Process by Reductive Decomposition (open access)

Fluidized-Bed Regeneration of Sulfated Dolomite from a Coal-Fired FBC Process by Reductive Decomposition

A fluidized-bed, reductive decomposition process has been developed for regenerating calcium sulfate, a product of fluidized-bed combustion. The effect of process operating variables on the extent of regeneration and on the SO2 levels in the off-gas has been determined, and a process model has been proposed. A process for regenerating spent SO2 sorbents has been developed on a PDU scale. Tymochtee dolomite that had been sulfated during fluidized-bed combustion of coal is regenerated (reductive decomposition of calcium sulfate to calcium oxide and SO2) by the incomplete combustion of either methane or coal in a fluidized-bed reactor.

Engineering Analysis of Thermal Phenomena for Lead-Acid Batteries During Recharge Processes (open access)

Engineering Analysis of Thermal Phenomena for Lead-Acid Batteries During Recharge Processes

Transient thermal phenomena in Pb/PbO2 (lead-acid) batteries during charging processes were investigated. Mathematical models were formulated for the studies of heat transfer behavior across the electrode/electrolyte interface within a porous PbO2 electrode during charging, thermal behavior and temperature distribution over a lead-acid battery during different charging processes designed for electric-vehicle propulsion application, and cooling methods for lead-acid batteries during recharge cycles. Numerical solutions show that the heat transfer across the solid electrode and the electrolyte within the porous electrode is so fast that their temperatures may be regarded as the same. The results also show that, in a lead-acid battery designed for electric-vehicle propulsion, the heat generated in the cell during fast charging processes may cause a noticeable rise of temperature in the cell if the heat is not removed properly. The studies of heat-removal processes indicate that incorporation of cooling tubes within the cell cannot effectively remove the heat being released from the cell. However, the heat may be removed effectively by circulation of electrolyte through the battery. Numerical solutions are provided for the engineering evaluation of heat-removal design during battery cycling processes.

Final Report of Fuel Dynamics Test E7 (open access)

Final Report of Fuel Dynamics Test E7

Test data from an in-pile failure experiment of high-power LMFBR-type fuel pins in a simulated $3/s transient-overpower (TOP) accident are reported and analyzed. Major conclusions are that (1) a series of cladding ruptures during the 100-ms period preceding fuel release injected small bursts of fission gas into the flow stream; (2) gas release influenced subsequent cladding melting and fuel release (there were no measurable FCI's (fuel-coolant interactions), and all fuel motion observed by the hodoscope was very slow); (3) the predominant post-failure fuel motion appears to be radial swelling that left a spongy fuel crust on the holder wall; (4) less than 4 to 6 percent of the fuel moved axially out of the original fuel zone, and most of this froze within a 10-cm region above the original top of the fuel zone to form the outlet blockage. An inlet blockage approximately 1 cm long was formed and consisted of large interconnected void regions. Both blockages began just beyond the ends of the fuel pellets.

A Comparison of the IBM 370/168 MODEL 3 with the Amdahl 470V/6 and the IBM 370/195 Using Benchmarks (open access)

A Comparison of the IBM 370/168 MODEL 3 with the Amdahl 470V/6 and the IBM 370/195 Using Benchmarks

As part of the studies preliminary to the acquisition of additional computing capability at Argonne National Laboratory, six groups of jobs were run on the IBM 370/195 at the Applied Mathematics Division of Argonne National Laboratory, on an Amdahl 470V/6 at the Amdahl manufacturing facilities in Sunnyvale, California, and on an IBM 370/168 MODEL 3 at the IBM Field Support Center in Gaithersburg, Maryland. This report compares the performance of the IBM 370/168 MOD 3 with that of the other two machines. Differences in machine configurations were minimized. The memory size of each machine was identical, the I/O configurations were as similar as possible, and the same versions of OS/MVT 21.7 and ASP 3.1 were used on all three machines. This allowed the comparison to be based on the relative performance of the three CPUs.

DETAILED ACCIDENT ANALYSIS FOR THE HIGH LEVEL WSTE PREPARATION PHASE OF THE COMMERCIAL NUCLEAR WASTE VITRIFICATION PROJECT (open access)

DETAILED ACCIDENT ANALYSIS FOR THE HIGH LEVEL WSTE PREPARATION PHASE OF THE COMMERCIAL NUCLEAR WASTE VITRIFICATION PROJECT

The environmental consequences and the probability of conceivable accidents occurring during the high level waste preparation (HLWP) phase of the Commercial Nuclear Waste Vitrification Project (CNWVP) were analyzed. The maximum environmental consequences of postulated accidents were calculated to result in low radiation doses: a 50-year dose commitment of 0.3 rem to the whole body for a maximum individual, and of 20 man-rem to the whole body for the surrounding population. This may be compared to Department of Energy (DOE) values, in Manual Chapter Appendix 0524, of 0.5-rem whole-body annual dose commitment to individuals at points of maximum probable exposure in uncontrolled areas. The calculated whole-body relative dose risk to individuals from accidents is low (1.6 x 10{sup -6} rem/yr) as compared to that received from natural background radiation (approximately 1.5 x 10{sup -1 } rem/yr) and as compared to levels specified in Nuclear Regulatory Commission (NRC) requirements for routine releases from nuclear power reactors (5.0 x 10{sup -3} rem/yr). Therefore, the design and operational plans for the HLWP phase are judged not to represent an undue environmental risk from accident conditions.

Economic study of low temperature geothermal energy in Lassen and Modoc counties, California (open access)

Economic study of low temperature geothermal energy in Lassen and Modoc counties, California

The purpose of this study was to investigate the feasibility of using low cost, low temperature geothermal energy in job-producing industries to increase employment and encourage economic development. The study, encompassing all of Lassen and modoc Counties, was to be site-specific, referencing candidate geothermal applications to known hot wells and springs as previously determined, or to new wells with specific characteristics as defined in the Scope of Work. The emphasis was to be placed on economically practical and readily achievable applications from known resources, thus complimenting the recently completed ERDA-Susanville Study where a designated community was used as a ''laboratory'' in which land-use planning, institutional aspects, geological assessments, technical modeling and socioeconomic impacts were all examined in overview. During the course of the study, monthly progress reports were prepared and reviewed with the Commission so that emphasis on particular features of study could be changed as necessary to reflect updated findings and to redirect efforts into additional areas of potential promise as they became apparent. In this manner, a degree of flexibility was maintained which allowed a more comprehensive study than would have been otherwise possible. Although the report generates both positive and negative findings in specific areas of investigation, …

Chemical Characterization of Basalt Flows (open access)

Chemical Characterization of Basalt Flows

The ARHCO chemical data which includes trace elements, can be used to distinguish, with a high degree of confidence, between flows in the upper (and part of the middle) Yakima basalts. They also can be used to distinguish between groupings of flows in the middle Yakima basalts, and between the lower basalts and the others. The quality of the measurements, however, was not well-controlled. The atomic absorption measurements were generally useful, but contained a significant number of poor values. The quality of the neutron activation data, with the exception of the Cr values, was generally well below that which can presently be done. Almost all data was either poorly calibrated (Sc, Co, Eu,Ba), had variations in calibration over an extended group of samples (La, Sm, Th, Ta), or had poor precision (Tb). The poorly (but consistently) calibrated data were useful for the basalt characterization and in particular the Cr measurements were very useful. The gamma ray spectroscopy measurements, which determined K, U and Th abundances, were generally of poor precision and not very useful for characterization of the basalts. They were helpful, however, in evaluating K and Th data taken by other methods. The emission spectroscopy measurements, with few exceptions, …

Environmental research needs for geothermal resources development. Volume I (open access)

Environmental research needs for geothermal resources development. Volume I

A detailed analysis was conducted to determine the adequacy of the total research efforts regarding the potential environmental impacts related to the exploration, drilling, production, and transmission stages of vapor-dominated, liquid-dominated, geopressured, and hot-dry-rock geothermal resources. The following environmental considerations were selected and analyzed in detail: air emissions (hydrogen sulfide, ammonia, mercury, boron, radon, etc.); liquid emissions (brine, and toxic chemicals); land subsidence; seismic activity; and noise. Following the definition of the problem and the assessment of the past and ongoing research efforts, environmental research needs were then recommended based on: (1) the severity of the environmental problems as perceived by literature and contacts with the research community; (2) probability of occurrence; (3) and the research dependency for a solution to that particular problem. The recommended research needs consisted of: (1) an evaluation of the past and ongoing research efforts to ascertain gaps in knowledge for a particular pollutant, process, or control technology; (2) baseline studies of air, soil, water, and ecology around the existing geothermal facilities and in the locations scheduled for future geothermal development; (3) need for the development of appropriate models for predicting concentration and dispersion of pollutants; (4) development of predictive models for potential health and …

Deprivation of Equations Describing Solute Transport in Ground Water (open access)

Deprivation of Equations Describing Solute Transport in Ground Water

Abstract: A general equation describing the three-dimensional transport and dispersion of a reacting solute in flowing ground water is derived from the principle of conservation of mass. The derivation presented in this report is more detailed but less rigorous than derivations published previously. The general solute-transport equation relates concentration changes to hydrodynamic dispersion, convective transport, fluid sources and sinks, and chemical reactions. Because both dispersion and convective transport depend on the velocity of ground-water flow, the solute-transport equation must be solved in conjunction with the ground-water flow equation.
