Nature of atmospheric dust. Progress report to January 15, 1955
Optical microscopic examination of air- and rain-borne dust shows most of the particles to be less than one micron in diameter. Electron microscopic examination of the same dust shows predominantly clusters of particles whose individual diameters are in the range 200 to 1000 A. The residue obtained by filtering rain water through a millipore filter is found to be slightly radioactive in more than half the cases observed.

Development of marketable solar assisted heat pumps. Phase II. Summary report, technical results
A water source heat pump has been designed that is capable of operating over the range from 40 to 110/sup 0/F entering water temperature and has a heating coefficient of performance greater than six in the upper portion of this range. A computerized heat pump balance program was written to allow the performance of either a water-to-water or a water-to-air heat pump to be predicted in either the heating or cooling mode. A detailed program description, flow charts, and sample outputs are appended. The balance program was used to specify components for a high efficiency water-to-water and a high efficiency water-to-air heat pump. Performance predictions for both units in heating and in cooling are included. The water-to-water and water-to-air performance predictions were compared. The water-to-air approach was clearly superior. A detailed design and layout was done for the three solar-assisted water-to-air heat pump. A horizontal configuration was chosen for marketability reasons. The design was made consistent with high quantity production equipment available in our factories and should result in the lowest possible manufacturing cost. A key question to be answered in this project is whether a reciprocating compressor can operate without damage at the high suction pressures characteristic to the …

Lithium--water--air battery project: progress during the months of August--November. [Development of prototype Al/air cell]
Work done on the Lithium--Water--Air Battery Research Program in the work period August through November, 1977, is summarized. A prototype single-cell fuel cell was developed. The single galvanic cell consists of two 30-cm square aluminum plates separated by a two-faced air cathode mockup. The purposes of the model are to determine ease and cost of electrode servicing and weight and manufacturing cost of the hardware. Projections of fuel cell performance and cost were made, based on the prototype cell and the performance of cells of similar anode--cathode spacing produced by Lockheed Missiles and Space Company. Performance is a strong function of the weight of water carried in the fuel cell, as water is the limiting reactant when sufficient aluminum is carried for a vehicle range of 1600 km. Research concerning the electrochemistry of calcium in aqueous chloride--hydroxide electrolytes is summarized with reference to a recent presentation of the work at the Fall Meeting of the Electrochemical Society. Polarization curves were obtained for the aluminum alloy used by Lockheed in fuel cell research. The experimental data agree closely with Lockheed's published results. 9 figures, 1 table.

Liquid-Phase Methanol Process Development Unit: Installation, Operation, and Support Studies. Technical Progress Report No. 1, 28 September 1981-31 December 1981
During this period the Work Breakdown Structure Dictionary was established. Task 1 was completed with submittal of the Project Work Plan and the Quality Assurance Manual. CSI produced basic process design information and a preliminary flowsheet for the LaPorte LPMeOH PDU. APCI developed the flowsheet further and set up the process on APCI's process simulator. The flowsheet development revealed a number of major changes necessary in the existing LPM pilot plant; this has led to pursuit of a unified design concept. Approval was requested for the unified design concept as well as advanced schedule for relocation of the LPM unit and advanced procurement of long delivery equipment items. A number of preliminary heat and material balances were calculated for the LPMeOH PDU and preliminary process specifications were prepared for the equipment items. The final design basis was established. The design pressure was set at 1000 psig. Eight design operating cases were defined for the following range of reactor operating conditions: Pressure - 500 to 900 psig, Temperature - 220 to 270/sup 0/C, Liquid-Fluidized Space Velocity - 1000 to 4000 l/hr-kg catalyst, Liquid-Entrained Space Velocity - 2000 to 10,000 l/hr-kg catalyst, and Liquid-Entrained Catalyst Loading - 0.1 to 0.4 kg catalyst/l …

Inelastic Strong Interactions at High Energies. [Cross Sections, Field Theory]
A method permitting the calculation of inclusive and semi-inclusive cross sections at high energies starting from an arbitrary field theory was worked out. The method relies on a functional integral representation of the generating functional of inclusive cross sections and on the use of semiclassical methods. The inclusive cross section is proportional to the absolute square of the Fourier transform of a special soliton solution of the classical field equations in zeroth order semi-classical approximation. A conserved topological quantum number that has a nonzero value for the soliton solution was found. Future research to be performed in this field under the contract is described including applications to various field theories and the exploration of connections with Reggeon field theory.

Simulation program for central helium liquefier
The computer program described here analyzes the performance of Fermilab Central Helium Liquefier (CHL) and predicts the values of the plant thermodynamic variables at all process points in the plant. To simulate CHL, this program is modified from the prototype program which was developed by Hitachi Ltd. a couple of years ago. This program takes care of only the steady state simulation and takes account of the change of the turbine efficiency, the pressure drops and the UA values of the heat exchangers. How to use the program is shown.

Pilot Plant Development Studies of a Continuous Process for Recovering Uranium From Nichrome Fuels
Pilot plant studies were conducted to develop a continuous process for recovering uranium from nichrome fuels (HTRE). The process consisted of dissolution of fuel in mixed HCl--HNO/sub 3/ solution, removal of the chloride ion by stripping with HNO/sub 3/ in a packed column, and then recovery of the uranium by TBP solvent extraction. Recovery of uranium from nichrome fuels at satisfactory rates and efficiencies can be obtained by this process. Reactor fuels containing large amounts of silica may present a solids problem during chloride removal. Titanium is a suitable material of construction for the dissolver, stripping column, and their associated equipment (feed, off-gas, and product vessels). Stainless steel equipment is suitable for the solvent extraction system. (auth)

Survey of Magnetic Fields Near BPA 230-kV and 500-kV Transmission Lines.
The purpose of this study was to characterize typical levels and variability of 60Hz magnetic fields at the centerline and edge of right-of-way of Bonneville Power Administration (BPA) 230-kV and 500-kV transmission lines. This was accomplished by taking magnetic field measurements at over 800 spans in Oregon and Washington. The spans were sampled using a stratified random sampling procedure with region (East vs. West), voltage (230-kV vs 500-kV), and circuit configuration as strata. There were five different circuit configuration groups for each region/voltage category requiring a total of 200 strata. Magnetic field measurements were taken at 13 locations under each span using an EMDEX-C as a survey meter. Additional information recorded for each span included conductor height (at 10 locations), right-of-way width, longitudinal and lateral slope, time of day, vegetation, terrain, weather conditions, temperature, wind speed, span length and presence of other lines in the corridor. 9 refs., 17 figs., 26 tabs.

Operating procedures: Fusion Experiments Analysis Facility
The Fusion Experiments Analysis Facility (FEAF) is a computer facility based on a DEC VAX 11/780 computer. It became operational in late 1982. At that time two manuals were written to aid users and staff in their interactions with the facility. This manual is designed as a reference to assist the FEAF staff in carrying out their responsibilities. It is meant to supplement equipment and software manuals supplied by the vendors. Also this manual provides the FEAF staff with a set of consistent, written guidelines for the daily operation of the facility.

The Effect of Chemical Additives on the Synthesis of Ethanol
The objective of this research is to elucidate the role of various chemical additives on ethanol synthesis over Rh- and Ni-based catalysts. Chemical additives used for this study will include S, P, Ag, Cu, Mn, and Na which have different electronegativities. The effect of additives on the surface state of the catalysts, heat of adsorption of reactant molecules, reaction intermediates, reaction pathways, reaction kinetics, and product distributions is/will be investigated by a series of experimental studies of NO adsorption, reaction probing, study state rate measurement, and transient kinetic study. A better understanding of the role of additives on the synthesis reaction may allow us to use chemical additives to manipulate the catalytic properties of Rh- and Ni-based catalysts for producing high yields of ethanol from syngas. 27 refs. 7 figs., 2 tabs.

Advective-diffusive/dispersive transport of chemically reacting species in hydrothermal systems. Final report, FY83-85
A general formulation of multi-phase fluid flow coupled to chemical reactions was developed based on a continuum description of porous media. A preliminary version of the computer code MCCTM was constructed which implemented the general equations for a single phase fluid. The computer code MCCTM incorporates mass transport by advection-diffusion/dispersion in a one-dimensional porous medium coupled to reversible and irreversible, homogeneous and heterogeneous chemical reactions. These reactions include aqueous complexing, oxidation/reduction reactions, ion exchange, and hydrolysis reactions of stoichiometric minerals. The code MCCTM uses a fully implicit finite difference algorithm. The code was tested against analytical calculations. Applications of the code included investigation of the propagation of sharp chemical reaction fronts, metasomatic alteration of microcline at elevated temperatures and pressures, and ion-exchange in a porous column. Finally numerical calculations describing fluid flow in crystalline rock in the presence of a temperature gradient were compared with experimental results for quartzite.

Automatic beam centering at the SSC interaction regions
In the SSC interaction regions, the two colliding beams, each only a few microns in size, will have to be centered and maintained in good alignment over many hours, in order to provide the maximum possible luminosity and to minimize off-center beam-beam focussing effects. It is unlikely that sufficiently good alignment can be achieved without some kind of active feedback system, based on the beam-beam interaction rate. This memo describes such a system. In the proposed scheme, one of the beams is moved continuously and in a circular fashion about its mean transverse position. The radius of this motion is approximately 0.01 of the rms beam size at the interaction point. The motion is achieved with two sets of crossed high frequency dipole magnets, one on each side of the interaction region, suitably phased. As a consequence of this motion, the beam-beam interaction rate is modulated in synchronism with the beam motion when the beams are not centered on one another. The amplitude and phase of this modulation yields information on the magnitude and direction of the misalignment between the beams, allowing continuous display and automatic correction of any misalignment.

Applications of Micellar Enzymology to Clean Coal Technology
This project is designed to develop methods for pre-combustion coal remediation by implementing recent advances in enzyme biochemistry. The novel approach of this study is incorporation of hydrophilic oxidative enzymes in reverse micelles in an organic solvent. Enzymes from commercial sources or microbial extracts are being investigated for their capacity to remove organic sulfur from coal by oxidation of the sulfur groups, splitting of C-S bonds and loss of sulfur as sulfuric acid Dibenzothiophene (DBT) and ehtylphenylsulfide (EPS)are serving as serving as models of organic sulfur-containing components of coal in initial studies.

Plutonium Residue Recovery (PuRR) project quarterly progress report, April--June 1989
A material-balance flowsheet for ash-heel processing has been prepared. The major process features are (1) reduction of Pu into a calcium-zinc alloy and selective electrolytic recovery of the Pu from the alloy, (2) removal of americium as a waste, (3) concentration of nontransuranic tramp elements in a zinc waste, (4) removal of oxygen and recovery of calcium by electrolysis of CaO, and (5) zinc recycle by evaporation. Based on this idealized flowsheet, the mass of solid waste is only 62% of that of the original residue. This is accomplished by recycling virtually all the reagents and discarding the oxygen as CO and CO{sub 2}. The pyrochemical recovery of Pu from incinerator ash heel from the Rocky Flats Plant was investigated. During this period, zinc-calcium alloys were used to reduce the PuC{sub 2} in the ash. Reduction of ash heel has been attempted with zinc-calcium alloys containing 2, 6, and 10 wt% calcium after the reduction. These resulted in extractions of 95%, 97%, and 99.5%, respectively, of the Pu from the salt. Following exposure of the reduction alloy to a ZnCl{sub 2}-bearing salt, the Pu was removed effectively from the alloy; however, the Pu recovered in the salt did not complete …

Ecological Sampling and Meteorological Calculation of Fallout on Forests Near Oak Ridge
Spatial patterns of radioactive contuamination on forest foliage were measured by gamma spectrometry and are discussed with respect to local vs. world- wide origin of the fallout and implications for ecology, health physics, and management of nuclear facilities. In September 1959, I/sup 131/ on dogwood leaf samples varied from over 500 mu mu c/g dry wt near Oak Ridge National Laboratory stacks to 1 to 7 mu mu c/g near the margins of the Oak Ridge Reservation. Stack fallout tended to occur closer to the source than was calculated from hourly wind data by an IBM 610 computer program based on Culkowski' s adaptation of the SuttonChamberlain theory of atmospheric diffusion and deposition. Over most of the Reservation levels of Ru/sup 106/ Cs/sup 137/ Zr/sup 9/ >s/sup 5/Nb/sup 95/ and Ce/sup 144/ were similar to levels found elsewhere (2 to 9, 1 to 3, 2 to 9, and 10 to 20 mu mu c/g respectively) and were presumably controlled by weapons fallout. Higher levels were found in small areas and indicate the need for attention to localized contamination, even though indirect estilevels considered hazardous from the standpoint of health physics.
