Advanced Selenide Thermoelectric Development Program. Final Report

Description: The primary objective of this work was to demonstrate that copper silver selenide and TAGS could be segmented. The hot junction temperature was planned to be 725/sup 0/C with the segmentation temperature at 400/sup 0/C, both temperatures were selected to prevent excessive sublimation from the hot ends of the segments, respectively. The program was planned as a cooperative effort between General Atomic company and Teledyne Energy Systems. Accordingly, General Atomic synthesized the CuAgSe that was used to fabricate the test hardware that was ultimately delivered to General Atomic for testing. Both the CuAgSe and TAGS were hot pressed in an argon atmosphere then the segments were furnace-bonded to each other. A secondary objective was to produce CuAgSe powder by rapid solidification.

Analysis of potential used oil recovery from individuals. Final report

Description: To assist the Department of Energy in its investigation of methods for recycling used motor oil, Market Facts conducted a telephone survey of individuals who change their own motor oil. The study examined the amount of oil used, oil change practices, oil disposal methods, and perceptions and attitudes toward used motor oil disposal and oil recycling. The results of this survey are presented in this report. The findings of this study confirm the generally held view that about half the vehicle households in the United States now do their own oil changes and additions. These do-it-yourselfers (DIY) households account for almost two-thirds of the motor oil consumed by all US households and produce about one-third of one billion gallons of used motor oil annually. At least half of this used motor oil, more than 170 million gallons, is returned to the environment in a form that pollutes the ground and endangers the water supply. Measures such as requiring information about proper disposal and the need for recycling used oil to be printed on motor oil containers have been taken in many states. The need for reminder advertising and reinforcement education and information and practical measures to ease the burden of compliance is suggested. These results suggest that careful consideration be given to the logistics of these measures. The most appealing of the measures would appear to be making a special container available to DIY oil changers. Employing civic groups as collection agents would also seem to be attractive.

Analysis of the risk of transporting uranium ore concentrates by truck

Description: This report evaluates the risks involved with shipping uranium ore concentrates by truck in an attempt to provide some perspective on the system safety issues. The basic probabilistic risk evaluation methodology used in this study is similar to that employed by Pacific Northwest Laboratory (PNL) in a series of risk analyses on the transportation of potentially hazardous energy materials. The risk model has been constructed as a series of separate analysis steps to allow the system risk to be readily reevaluated as additional data become available or as postulated system characteristics change. The reslts of this analysis show that the risks to the public health and safety from yellowcake releases during a transportation accident are insignificant. Accidents involving truck shipments of yellowcake are expected to occur at a rate of about ten a year. However, only one-fifth of these accidents, or about two a year, are expected to cause a release of yellowcake to the environment. None of these accidents was estimated to produce any potential fatalities. The low concentration of radioactivity distributed throughout the material resulted in no significant increase in radiation doses above normal background levels to members of the general public.

Analytical theory of interchange and compressional Alfven instabilities in EBT

Description: The local stability of the EBT plasma is analyzed for the long wavelength perturbations in the frequency regime, ..omega.. approx. less than or equal to ..cap omega../sub i/(..cap omega../sub i/ is ion cyclotron frequency). In addition to the low frequency interchange instability, the plasma can be unstable to the compressional Alfven wave. Contrary to the previously obtained quadratic dispersion relation in ..omega.. for the interchange mode, our dispersion relations for both types of instabilities are cubic in ..omega... New stability boundaries are found, for the hot electron interchange mode, to relate to the enhanced compressibility of the core plasma in the presence of hot electrons. The compressional Alfven instability is driven due to the coupling of hot electron magnetic drifts and diamagnetic drift with the compressional Alfven wave. The stability conditions of these two types of instabilities are opposite to each other.

Antiproton Yields for Stochastic Accumulation

Description: Two sets of parameters have been developed to study stochastic accumulation. The question arises of the size of the transverse emittance required to achieve an antiproton yield of 1.2 x 10{sup 8} {bar p}'s/MR cyc1e for 4.5 GeV and 8 GeV {bar p} kinetic energies, given a full momentum acceptance of 4%. The results quoted in the paper are obtained with a Monte Carlo program which uses a fit to the {bar p} production invariant cross section that has been presented previously. An article describing the program is in preparation.

Assessment of precision gamma scanning for inspecting LWR fuel rods. Final report

Description: Reconstruction of the radial two-dimensional distributions of fission products using projections obtained by nondestructive gamma scanning was evaluated. The filtered backprojection algorithm provided the best reconstruction for simulated gamma-ray sources, as well as for actual irradiated fuel material. Both a low-burnup (11.5 GWd/tU) light-water reactor fuel rod and a high-burnup (179.1 GWd/tU) fast breeder reactor fuel rod were examined using this technique.

Assessment of radiation effects in defense transuranic waste forms

Description: The actinide concentrations of the defense transuranic (TRU) wastes were analyzed and the potential effects of the radiation on the properties of the wastes after conversion to immobile forms were assessed. The study focused on the contact-handled retrievably-stored wastes. The major components of the current inventory are defense plutonium-contaminated wastes containing various amounts of /sup 241/Am. The wastes stored at Idaho National Engineering Laboratory (INEL) are typical of the wastes in this category. There is also a substantial amount of wastes contaminated with plutonium enriched in /sup 238/Pu arising from the Department of Energy's isotopic heat-source programs. Most of these wastes are stored at the Los Alamos National Laboratory (LANL) and the Savannah River Plant (SRP) sites. Four reference wastes were selected representing a credible range of actinide activities and were used for estimating radiation doses to the final waste forms based on: INEL first stage sludge, a composite of all wastes at INEL, a composite of all wastes at LANL including both defense and heat source plutonium wastes, and a composite of all heat-source plutonium wastes at SRP free from defense plutonium. From integrated alpha and beta-gamma doses over a 10/sup 5/y storage period, it is concluded that: accumulated beta-gamma doses of 10/sup 6/ to 10/sup 8/ rad over a 10/sup 5/ y storage period will not significantly change physical properties of the waste form. The alpha decay doses are 3-30 x 10/sup 16/ decays/cm/sup 3/ (up to 3 x 10/sup 10/ rad ionizing radiation from alpha particles) accumulated over a 10/sup 5/ y storage period. Radiolytic gas generation can be substantial in waste forms containing water or organic materials. The effect of leachant radiolysis on the leachabilities of TRU waste forms is not sufficiently understood to rule out the need for testing with actinide-doped specimens.

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.

Automated Fresnel lens tester system

Description: An automated data collection system controlled by a desktop computer has been developed for testing Fresnel concentrators (lenses) intended for solar energy applications. The system maps the two-dimensional irradiance pattern (image) formed in a plane parallel to the lens, whereas the lens and detector assembly track the sun. A point detector silicon diode (0.5-mm-dia active area) measures the irradiance at each point of an operator-defined rectilinear grid of data positions. Comparison with a second detector measuring solar insolation levels results in solar concentration ratios over the image plane. Summation of image plane energies allows calculation of lens efficiencies for various solar cell sizes. Various graphical plots of concentration ratio data help to visualize energy distribution patterns.

Ballooning stability in toroidal devices

Description: The marginal stability condition of ballooning instabilities for toroidal confinement devices is derived for low critical stability ..beta.. (..beta.. less than or equal to 10%). The stability condition derived here should be applicable to EBT and multipoles as well as tokamaks and stellarators. For EBT and multipoles a more compact expression for the stability condition is possible and is given here in the appendix.

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.

Basin View Geothermal Heating District, Klamath Falls, Oregon: conceptual design and economic-feasibility study report

Description: The findings of a feasibility study performed for Basin View Heating District in Klamath Falls, Oregon are reported. The purpose of the study is to determine the physical, economic, and political feasibility of establishing a geothermal heating district to provide space heat to housing units in the Basin View Development of Klamath Falls. Of the several systems considered, all are physically feasible. The project is politically feasible if the owner compiles with governmental requirements. Economic feasibility is based on considerations of money value rates, tax rates and expected rates of return, which are dependent on government and money markets. For analysis a money value rate of 21% and an owner's marginal tax rate of 35% were adopted.

Beam propagation in the frequency-converted subsystems of Nova and Novette

Description: An analysis of beam propagation for the frequency converted Nova/Novette systems is given and self-focusing effects are reviewed. It is shown that the nonlinear growth of beam modulation produced by self-focusing is proportional 1/2 exp B where B is the intensity dependent phase retardation (measured in radians) accumulated by the beam. This exponential growth of beam modulation in the baseline frequency conversion/focusing optical train limits the system performance for short pulse (tau < 2 ns), one third micron operation. One micron and one-half micron performance are limited more by the one micron drive available to frequency conversion KDP array than self-focusing.
