Minimal relativistic three-particle equations

Description: A minimal self-consistent set of covariant and unitary three-particle equations is presented. Numerical results are obtained for three-particle bound states, elastic scattering and rearrangement of bound pairs with a third particle, and amplitudes for breakup into states of three free particles. The mathematical form of the three-particle bound state equations is explored; constraints are set upon the range of eigenvalues and number of eigenstates of these one parameter equations. The behavior of the number of eigenstates as the two-body binding energy decreases to zero in a covariant context generalizes results previously obtained non-relativistically by V. Efimov.

Risk perception, risk evaluation and human values: cognitive bases of acceptability of a radioactive waste repository

Description: Public acceptance of radioactive waste management alternatives depends in part on public perception of the associated risks. Three aspects of those perceived risks were explored in this study: (1) synthetic measures of risk perception based on judgments of probability and consequences; (2) acceptability of hypothetical radioactive waste policies, and (3) effects of human values on risk perception. Both the work on synthetic measures of risk perception and on the acceptability of hypothetical policies included investigations of three categories of risk: (1) Short-term public risk (affecting persons living when the wastes are created), (2) Long-term public risk (affecting persons living after the time the wastes were created), and (3) Occupational risk (affecting persons working with the radioactive wastes). The human values work related to public risk perception in general, across categories of persons affected. Respondents were selected according to a purposive sampling strategy.

New facility shield design criteria

Description: The purpose of the criteria presented here is to provide standard guidance for the design of nuclear radiation shields thoughout new facilities. These criteria are required to assure a consistent and integrated design that can be operated safely and economically within the DOE standards. The scope of this report is confined to the consideration of radiation shielding for contained sources. The whole body dose limit established by the DOE applies to all doses which are generally distributed throughout the trunk of the body. Therefore, where the whole body is the critical organ for an internally deposited radionuclide, the whole body dose limit applies to the sum of doses received must assure control of the concentration of radionuclides in the building atmosphere and thereby limit the dose from internal sources.

Economic evaluation of volume reduction for Defense transuranic waste

Description: This study evaluates the economics of volume reduction of retrievably stored and newly generated DOE transuranic waste by comparing the costs of reduction of the waste with the savings possible in transportation and disposal of the waste. The report develops a general approach to the comparison of TRU waste volume reduction costs and cost savings, establishes an initial set of cost data, and develops conclusions to support selecting technologies and facilities for the disposal of DOE transuranic waste. Section I outlines the analysis which considers seven types of volume reduction from incineration and compaction of combustibles to compaction, size reduction, shredding, melting, and decontamination of metals. The study considers the volume reduction of contact-handled newly generated, and retrievably stored DOE transuranic waste. Section II of this report describes the analytical approach, assumptions, and flow of waste material through sites. Section III presents the waste inventories, disposal, and transportation savings with volume reduction and the volume reduction techniques and savings.

Ion Bernstein-wave excitation via finite-Larmor-radius mode-transformation process

Description: It is shown that in the ion cyclotron range of frequency ..omega.. less than or equal to 2 ..cap omega../sub i/, the finite-Larmor-radius effect removes the wave singularity at the lower-hybrid resonance layer, enabling an externally initiated electron plasma wave to propagate freely through the resonance layer, transforming continuously into an ion Bernstein wave. In an ACT-1 hydrogen plasma (T/sub e/ approx. = 2.5 eV, T/sub i/ approx. = 1.5 eV), linear excitation of ion Bernstein waves has been investigated experimentally for ..omega.. approx. = 2..cap omega../sub i/. The mode-transformation process resulting in a strong ..omega.. approx. = 2 ..cap omega../sub i/ ion Berstein wave excitation without observable reflections has been experimentally verified. Detailed measurements of wave dispersion relation and of the wave-packet trajectory show excellent agreement with theory.

Power-crowbar impacts on plasma characteristics in ZT-40

Description: Detailed analysis of the impact of I/sub phi/ and I/sub theta/ power crowbars on the ZT-40 plasma is presented for the operational period between shots 1620-3600. It is demonstrated that in both aided- and self-reversed modes the main effect of the I/sub phi/ power crowbar is to lengthen the time to l/e of peak current, whereas the main effect of the I/sub theta/ power crowbar is to extend the reversal of B/sub phi/ at the wall, primarily in self-reversed operation. It is shown that this extension has the effect of also decreasing the current decay rate to the point where no distinction is seen between the two modes. A saturation is seen in the decay time (tau/sub l/e/ less than or equal to 0.4 ms) once the field reversal in either mode exceeds approximately 0.3 ms. Possible physical explanations of these effects are discussed.

Balmer alpha emission and hydrogen atom energy in ion-source discharges

Description: The structure of the hydrogen Balmer alpha line emission profiles from three types of neutral beam injector ion source plasmas (filling pressure approx. 10 mTorr, electron density approx. 1 to 2 x 10/sup 12/ cm/sup -3/, electron temperature approx. 2 to 4 eV) is studied with the aid of a simple model for the neutral particle balance and H/sub ..cap alpha../ emission. A large fraction of the H/sub ..cap alpha../ is produced by dissociative excitation of H/sub 2/ and dissociative recombination of H/sub 2//sup +/, while the remainder is produced by excitation of H atoms, most of which have energies that are close to the characteristic H/sub 2/ dissociation energies. The H/sub ..cap alpha../ linewidth is thus insensitive to the discharge operating conditions and equals approx. 0.27 A when only slow (approx. 0.3 eV) dissociatively excited atoms are present or approx. 0.35 A when fast (> 1 eV) atoms, apparently also produced in dissociation reactions, are present as well.

Volatile production during preignition coal heating. Quarterly progress report, April 1981 - June 1981

Description: The goal of this program is to determine the characteristic pyrolysis behavior of representative coals under laser heating. The use of a CO/sub 2/ laser enables a controllable heating rate to be given to the coal particles as they pass through the laser beam. The development of such a laser heating diagnostic should prove to be an extremely valuable tool for generation of a data base necessary for the future design of coal burning facilities. The experimental configuration is illustrated. A dilute coal/gas stream, surrounded aby an inert shield flow is passed through a laser beam from an Avco HPL CO/sub 2/ laser. Under a prescribed flux density, and thus heating rate, the particle pyrolyse. The gaseous products are sampled and subsequently analyzed (primarily by gas chromatography) for carbon conversion. Particle temperature is to be monitored by a two-color pyrometer and particle velocity by laser Doppler velocimeter, by which means, evolution of the pyrolysis process can be determined.

Assessment of the computer code COBRA/CFTL

Description: The COBRA/CFTL code has been developed by Oak Ridge National Laboratory (ORNL) for thermal-hydraulic analysis of simulated gas-cooled fast breeder reactor (GCFR) core assemblies to be tested in the core flow test loop (CFTL). The COBRA/CFTL code was obtained by modifying the General Atomic code COBRA*GCFR. This report discusses these modifications, compares the two code results for three cases which represent conditions from fully rough turbulent flow to laminar flow. Case 1 represented fully rough turbulent flow in the bundle. Cases 2 and 3 represented laminar and transition flow regimes. The required input for the COBRA/CFTL code, a sample problem input/output and the code listing are included in the Appendices.

Assessment of the geothermal potential of southwestern New Mexico. Final report, July 1, 1978-April 30, 1980

Description: Results are reported of geologic mapping of geothermal anomalies in the Gila Hot Springs KGRA/Mimbres Hot Springs area, Grant County. They suggest that both hot-spring occurrences are structurally controlled by the intersection of a major Basin and Range fault and the disturbed margin of an ash-flow tuff cauldron. Hydrothermal alteration in both areas is related to mid-Tertiary volcanism, not to modern hot springs. At Gila Hot Springs, the geothermal aquifer is a zone at the contact between the unwelded top of a major ash-flow tuff sheet (Bloodgood Canyon Rhyolite Tuff) and a succession of interlayered vesicular basaltic andesite flows and thin sandstone beds (Bearwallow Mountain Formation). Scattered groups of natural hot springs occur at intersections of this zone and the faults bordering the northeastern side of the Gila Hot Springs graben. Hydrothermal alteration of Bloodgood Canyon Rhyolite Tuff near major faults seems to have increased its permeability. At Mimbres Hot Springs, a single group of hot springs is controlled by the intersection of the Mimbres Hot Springs fault and a fractured welded ash-flow tuff that fills the Emory cauldron (Kneeling Nun Tuff). Gila Hot Springs and Mimbres Hot Springs do not seem to be connected by throughgoing faults. At both localities, hot spring water is used locally for space heating and domestic hot water; at Gila Hot Springs, water of 65.6/sup 0/C (150/sup 0/F) is used to generate electricity by means of a 10 kw freon Rankine Cycle engine. This is the first such application in New Mexico.

Review of nitrogen laser research, 1963-1973

Description: This report is broken up into seven sections. The body begins with a description of exploratory, experimental nitrogen lasers; this description is done chronologically. Physical insights gained during the course of these experiments are also introduced chronologically so as to aid the reader in appreciating the improvements and disadvantages of successive approaches to the problem. A review is given of previously accepted models of this laser. The models presented are based on assumed inversion mechanisms which have recently been called into doubt. The fifth section of this report is a short one on the uses of the pulsed nitrogen laser; the sixth is the appendix where the details of devices discussed are summarized. To actually build a nitrogen laser, the best approach, short of solving the problem theoretically first, would be to peruse the appendix to get an idea of what would be involved and what to expect. The seventh section consists of the figures which give many of the numbers not discussed explicitly in the text, nor adequately displayed in the appendix.

Managing for success: developing and exploiting international opportunities in geothermal energy

Description: This study is designed to assist the Division of Geothermal Energy (DGE) in deciding what kind of strategy it wants and needs in order to make its international effort as cost-effective and appropriate as possible. The purpose of this study is to construct a logic base on which DGE can, in turn, establish its own strategy for international cooperation, and can begin to plan for necessary organization, procedural and policy reforms. This report will constitute a set of decision guidelines for DGE to consider in determining the nature of future strategy-related reforms. Each chapter asks, and then answers, the question on which it is centered as follows: (1) what are the deficiencies in DGE's current approach; (2) what should an international strategy for DGE ensure; (3) how can an international strategy for DGE be manifested; (4) which strategic model presents the best opportunity now; and (5) how can the recommended alternative be achieved.

Characterization of geothermal solid wastes

Description: The compositions of 5 major types of geothermal wastes have been determined, and samples have been subjected to EPA recommended extraction tests to determine if they contain toxic metals that would classify the wastes as hazardous. Of the samples tested, the extracts of geothermal brines clearly contain levels of As, Ba and Pb exceeding the maximum allowed concentrations that characterize wastes as toxic. Only one other waste type, geothermal scale, exhibited EP toxicity. Pb was found in the extract of geothermal scale at a level of 7 mg/l, only 2 mg/l over the maximum limit. All of the other types of geothermal waste samples showed levels of toxic metals in the extracts well below the regulated limits.

Brayton-cycle heat recovery-system characterization program. Subatmospheric-system test report

Description: The turbine tests and results for the Brayton cycle subatmospheric system (SAS) are summarized. A scaled model turbine was operated in the same environment as that which a full-scale SAS machine would experience from the hot effluent flue gas from a glass container furnace. The objective of the testing was to evaluate the effects of a simulated furnace flue gas stream on the turbine nozzles and blades. The following specific areas were evaluated: erosion of the turbine nozzles and blades from the dust in the flue gas, hot corrosion from alkali metal salts in the dust and acid vapor (sulfur trioxide and hydrogen chloride) in the flue gas, and fouling and flow blockage due to deposition and/or condensation from the flue gas constituents.
