Stress studies in EFG. Fourth quarterly progress report, April 1, 1983-June 30, 1983

Description: Stress distributions have been calculated for a creep law predicting a higher rate of plastic deformation than modeled in earlier studies. The expected reduction in stresses is obtained, although quantitative results are not yet available because of difficulties in obtaining convergent solutions. Improved schemes for calculating growth system temperature distributions are being evaluated in a new subtask started at MIT. Other work in temperature field modeling has examined the possibility of using horizontal temperature gradients to influence stress distributions in ribbon. The defect structure of 10 cm wide ribbon grown in the cartridge system has been examined. A new feature is identified from an examination of cross-sectional micrographs. It consists of high density dislocation bands extending through the ribbon thickness. A four-point bending apparatus has been constructed for high temperature (greater than or equal to 1000/sup 0/C) study of the creep response of silicon, and will be used to generate defects for comparison with as-grown defects in ribbon. Another subtask has been started in collaboration with the University of Illinois which will examine the feasibility of laser interferometric techniques for sheet residual stress distribution measurement. The mathematical formalism for calculating residual stress from changes in surface topology caused by an applied stress in a rectangular specimen has been developed, and the system for laser interferometric measurement to obtain surface topology data has been successfully tested on CZ silicon. Testing and calibration of different fiber optics temperature sensor configurations are underway.

Toxicology and metabolism of nickel compounds. Progress report, December 1, 1978-November 30, 1979. [Hamsters and rats]

Description: The toxicology and metabolism of nickel compounds were investigated in rats and hamsters. The new knowledge includes; demonstration that nickel carbonyl is teratogenic for hamsters; elucidation of physiological factors which influence ..cap alpha..Ni/sub 3/S/sub 2/-induced erythrocytosis in rats; development of a sensitive assay for heme oxygenase activity in renal microsomes for use in studies of renal effects of nickel compounds; demonstration that administration of Ni(CO)/sub 4/ to rats inhibits incorporation of /sup 3/H-thymidine into DNA during hepatic regeneration; demonstration that clones of Syrian hamster fetal cells which have been transformed by in vitro exposure to ..cap alpha..Ni/sub 3/S/sub 2/ consistently cause sarcomas following sc injection into nude mice; demonstration that nickel carbonyl-cyclopentadiene dimer induces rhabdomyosarcomas following im injection in rats; observation of differences in carcinogenic activities of several insoluble nickel compounds; discovery that intraocular injection of ..cap alpha..Ni/sub 3/S/sub 2/ induces amelanotic melanomas in rats; and refinement of analytical methods for nickel in biological materials.

Characterization and analysis of Devonian shales as related to release of gaseous hydrocarbons. Well N-1 Henderson County, Illinois and Well N-2 Tazewell County, Illinois

Description: Core sampling, hydrocarbon gas contents, chemical and physical characterization data are presented. Core samples from these two Illinois basin wells were obtained in July and August 1977. Thirty-one and twenty-three samples were obtained from N-1 and N-2 wells, respectively, amounting to total core length of 940 feet. Shales from Illinois basin wells (such as N-1 and N-2) are characterized by very low hydrocarbon gas contents. In fact, the N-1 and N-2 wells exhibited the lowest hydrocarbon gas contents among all the wells thus far analyzed. The chemical analysis of these shales also indicates rather low carbon and hydrogen contents, supporting the hydrocarbon gas release data. One significant aspect of the physical characterization data is high porosity associated with low bulk densities. N-1 and N-2 shales exhibit the highest pore volume of any shales from either basin (Appliachian and Illinois). Lithology of these shales does not significantly differ from those of other locations. These shales exhibit relatively low carbonates.

Sources of ozone and sulfate in northeastern United States. Annual progress report. [Determination of anthropogenic sources from measurements at Whiteface Mountain, New York]

Description: Measurements of daily concentrations of /sup 7/Be, /sup 32/P, and ozone at Whiteface Mountain, New York are reported for June, July, and August of 1977 and 1978. Episodes of high daily ozone are observed to coincide with peak /sup 7/Be and /sup 32/P concentrations. Since these radionuclides and ozone are produced in the stratosphere, their simultaneous increase is taken to indicate the arrival of stratospheric air. However, ozone is also produced at ground level by photochemical reactions. Therefore, only when the ground level production of ozone is small can a comparison of cosmogenic nuclides and ozone quantitatively yield stratospheric ozone component. On June 15, 1977 at least 80% of the 50 ppBv (daily average) ozone observed originated in the stratosphere. Our data indicate substantial stratospheric contributions on numerous other occasions. The /sup 7/Be and /sup 32/P concentration measurements can be used to directly determine the accompanying stratospheric ozone if (1) the /sup 7/Be (and/or /sup 32/P)O/sub 3/ mixing ratios in the upper atmosphere, and (2) mean residence time of O/sub 3/ are known. Since October 1977, the /sup 7/Be concentrations in aerosol samples collected at 10 to 12 km varied from less than or equal to 0.1 to 5.8 pCi/kg air, whereas ozone concentrations ranged between 27 and 527 ppBv. If the mean residence times and /sup 7/Be/O/sub 3/ ratios are known, ground level /sup 7/Be concentration will yield the stratosphericozone concentration. Estimated dialy stratospheric ozone components vary from 10 to 40 ppBv. Measurements of total suspended particulates (TSP), trace elements, and sulfates were also carried out. Since these are produced only at ground level, their daily variations indicate the intensity of pollutant transport from urban/industrial centers to rural Whiteface Mountain. Comparison of the elevated episodic concentrations with surface air mass trajectories show that the polluted air masses originated in …

Pilot aerial infrared roof top survey. Final report

Description: A summary is presented of a pilot aerial infrared roof top study conducted by the Minnesota Energy Agency. Infrared surveys of 27 Minnesota cities were conducted during the fall and winter of the 1976-1977 heating season. In addition, conventional daytime color photographs were taken of several cities. Film processing was done by the Environmental Protection Agency. The University of Minnesota conducted ground tests to verify the aerial infrared imagery. Thermograph dissemination centers were established in each city and training seminars and materials were prepared and delivered to dissemination center staff. A survey of homeowners who viewed their thermograph at a dissemination center were used to determine the energy savings resulting from the program. An Aerial Infrared Program Users Manual was prepared by the Energy Agency and the Remote Sensing Institute of Brookings, South Dakota.

Towards unified performance measures for evaluating nuclear safeguard systems: mathematical foundations and formal comparison of existing models

Description: An important step in the analysis of large-scale systems is the development of economical and meaningful measures of system performance. In the literature on analysis of nuclear safeguard systems, many performance measures have been advanced, but their interrelationships and their relevance to overall system objectives have not received attention commensurate with the effort spent in developing detailed safeguard models. The work reported here is an attempt to improve the development and evaluation of performance measures for nuclear safeguard systems. This work falls into three main areas. First, we develop a new framework which provides an initial basis for defining and structuring performance measures. To demonstrate that this framework allows a clear understanding of the purposes of nuclear safeguard systems, we employ it to state various safeguard questions clearly and concisely. The framework reflects the rough subsystem structure of safeguard systems - the detection and response subsystems - and formally accommodates various safeguard models. We especially emphasize two of these models which are under development at Lawrence Livermore Laboratory, the structured assessment approach (SAA) and the systems vulnerability assessment method (SVAM). Second, we examine some performance measures presently used in the nuclear safeguards area and in reliability theory in general. Some of these we accept and modify to obtain system performance measures that are an additive combination of subsystem performance measures, a very convenient form indeed. Others we reject as impractical and meaningless. Finally, we determine some common features between the SAA and SVAM models by formally comparing these models in our framework.

Evaluation of selected chemical processes for production of low-cost silicon (Phase III). Fifteenth quarterly progress report, April 1-June 30, 1979

Description: Progress has been made during this quarter on the assembly of the Process Development Unit (PDU) consisting of four of the critical components of the 50 MT/year Experimental Process System Development Unit (EPSDU) for the production of granular semiconductor-grade silicon by the zinc vapor reduction of silicon tetrachloride in a fluidized bed of seed particles. The target operation date of October 1, 1979, still appears attainable. An experimental wetted-wall condenser, about 1/10 the size of the PDU/EPSDU design was operated to demonstrate that recirculated liquid zinc chloride can indeed be used to wash down the condensed by-product of the fluidized-bed reactor containing finely divided solid zinc and some silicon dust. The temperature distribution proved to be more critical than anticipated but the condenser now appears to be operable. Some improvement in condensation efficiency is desirable, however. Procedures were established for safe handling of SiCl/sub 4/ leaks and spills from the EPSDU and PDU. Preparations are being made to conduct zinc vaporization experiments in that portion of the PDU before operation of the entire PDU is initiated.

Mathematical model of the Savannah River Site waste tank farm

Description: A mathematical model has been developed to simulate operation of the waste tank farm and the associated evaporator systems at the Savannah River Site. The model solves material balance equations to predict the volumes of liquid waste, salt, and sludge for all of the tanks within each of the evaporator systems. Additional logic is included to model the behavior of waste tanks not directly associated with the evaporators. Input parameters include the Material Management Plan forecast of canyon operations, specification of other waste sources for the evaporator systems, evaporator operating characteristics, and salt and sludge removal schedules. The model determines how the evaporators will operate, when waste transfers can be made, and waste accumulation rates. Output from the model includes waste tank contents, summaries of systems operations, and reports of space gain and the remaining capacity to store waste materials within the tank farm. Model simulations can be made to predict waste tank capacities on a daily basis for up to 20 years. The model is coded as a set of three computer programs designed to run on either IBM compatible or Apple Macintosh II personal computers.

Implementation study for the NRC Application and Development Facility

Description: The Nuclear Regulatory Commission (NRC) has expressed the desire to establish an Application and Development Facility (ADF) for NRC Headquarters. The ADF is a computer system which will provide safeguards analysts access to safeguards analysis computer software. This report analyzes the issues, requirements and options available in the establishment of an ADF. The purpose and goals of the ADF are presented, along with some general issues to be considered in the implementation of such a system. A phased approach for ADF implementation, which will allow for the earliest possible access to existing codes and also allow for future expansion, is outlined. Several options for central computers are discussed, along with the characteristics and approximate costs for each. The report concludes with recommended actions proposed to start the development of the ADF.

Kinetics of growth and decay of excited rare-gas atoms and molecules in the pulse radiolysis of pure rare gases and of mixtures of rare gases with molecular quenching agents

Description: The temporal behavior of vibrationally relaxed first triplet Kr/sub 2/ in the presence of N/sub 2/ has been examined, and the rate constant for destructive quenching by N/sub 2/ has been evaluated at 298K. Its value is of the same order of magnitude as that for quenching of first triplet Ar/sub 2/, but is somewhat smaller. This suggests that the krypton and argon excimers excite different electronic states of N/sub 2/, the former leading to N/sub 2/(A) and N/sub 2/(B) and the latter principally to N/sub 2/(C), in accord with the general rule that near-resonant energy transfer tends to be favored over events which form products bearing significant translational energy. A new value for the spontaneous radiative decay constant of vibrationally relaxed first triplet Kr/sub 2/ has also been determined. A generalized mechanism for decay of Paschen(ls) atoms and for concomitant growth and decay of bound-state excimer molecules has been developed. Modelling calculations have shown that decay constants for Ar(/sup 3/P/sub 2/) measured at low (1 to 20 torr) and high (100 to 700 torr) pressures are not discrepant with respect to one another and can be precisely fitted with the generalized mechanism. Implications regarding the temporal behavior of vibrationally relaxed Ed/sub 2/ excimers are also discussed. Data obtained by single frequency laser probe monitoring of Ar(/sup 3/P/sub 2/) suggests that, although the ls-2p absorption lines are of Lorentzian form at 700 torr, as expected, the apparent line width narrows with increasing time. The cause of this phenomenon has not yet been identified.

Phase 2 of the array automated assembly task for the Low Cost Solar Array Project. Quarterly report no. 6, January 1-March 31, 1979

Description: Using silk screened evaporated and sputtered Al as the metal source, the formation of Al back surface fields (BSF) was studied. The most satisfactory results were those obtained with the sputtered Al and in which open circuit voltages (V/sub oc/) of 0.585v (12 ..cap omega.. cm FZ silicon) have been achieved. The ultrasonic interconnect process is being verified. The process is generally satisfactory, but increased pull-strength may be obtained if some form of sintering is carried out on the metallized contacts. Plasma etching has been shown to be feasible as a replacement for wet chemical cleaning prior to diffusion. An IPEG calculation shows its cost to be $0.005/watt peak (1975$). Initial results on cells prepared by using electroless Pd/Ni plus either electroplated Ag or Cu have shown slightly poor performance than cells with the baseline evaporated Ti/Pd/Ag system. This is being further studied. A new mask has been designed for the 1.6 x 7.0 cm and 2.0 x 7.0 cm cells. This mask has a lower coverage and total lower resistive loss than the previous mask design. It is also shown that the cell width should not exceed 2.0 to 3.0 cm for optimum efficiency.

Basic Combustion and Pollutant-Formation Processes for Pulverized Fuels. Quarterly Technical Progress Report No. 4, 1 July 1981-30 September 1981

Description: This contract study of basic combustion and pollutant formation processes for pulverized solid fossil fuels includes coal-water mixtures and chars derived from coal pyrolysis, liquefaction or gasification processes. The factors that affect the physical properties of coal-water mixtures (CWM) have been identified and characterization tests initiated to determine how these variables (e.g., solids loading, particle size, particle size distribution, additives) affect the coal slurries. A bench-scale apparatus consisting of a pressure vessel and an atomizing nozzle was designed and is being fabricated. This apparatus will assist in the development of handling and atomization techniques for the combustion tests. It will also aid in comparing viscosities of slurries of different solids loadings and coal types. Chars were obtained for characterization tests. A series of potential tests to characterize the chars was identified. Grading and sizing of the chars was begun as well as elemental analysis. Samples of the chars were sent to Phillips for CO/sub 2/ reactivity tests to be performed. Coding for incorporation of swirling flows into the two-dimensional coal combustion model (PCGC-2) was completed. Debugging was initiated and sample computations are performed for a gaseous, isothermal system for low swirl numbers. Convergence problems were encountered when attempts were made to complete runs at higher swirl numbers.

Hydrologic properties of shale and related argillaceous rocks

Description: This report is the result of a bibliographic study designed primarily to collect hydrologic data on American clay-rich rocks. The following information was also sought: stratigraphy, environment of deposition, mineralogic composition, and diagenetic changes. The collected numerical data are presented in tables which contain densities, porosities, and/or hydraulic conductivities of approximately 360 samples. Additional data include hydraulic diffusivities, resistivities, flow rates, and rock strengths. Geologic information suggests that large deposits of shale which may be suited for waste repository belong to all ages and were formed in both marine and continental environments. Of the studied units, the most promising are Paleozoic in the eastern half of the country, Mesozoic in the central part, and Cenozoic in the Gulf Coast area and the West. Less widespread units locally present some additional possibilities. Mineralogic investigations suggest that the smectite content in rocks shows a decrease in time (70% in Recent rocks; 35% in pre-Mesozoic rocks). Because of this predominance of smectite in younger rocks, the modeling of repositories in post-Paleozoic formations might require knowledge of additional and poorly known parameters. Results of investigations into the mathematical relationships between porosity and permeability (or hydralic conductivity) suggest that in situ permeabilities could be estimated from sonic logs and fluid pressure changes at depth. 16 figures, 8 tables.

Electron Transfer Reactions of Excited Dyes With Metal Complexes. Progress Report, March 1, 1978-February 28, 1979. [Iron-Methylene Blue]

Description: An intense absorption band of /sup 3/MBH/sup 2 +/ at 700nm was characterized in several media and its pK/sub A/ was measured to be 7.17 +- .1 in water. Flash photolysis show that semiethylene blue, MBH/sup +/, formed by quenching /sup 3/MBH/sup 2 +/ with Fe/sub II/(H/sub 2/O)/sub 6//sup 2 +/, decays by disproportionation at a diffusion-controlled rate. Rates of decay of the photostationary state of solutions of MB/sup +/ and Fe/sup II/(H/sub 2/O)/sub 6//sup 2 +/ in acidic media were measured using crossed beams to yield specific rates of oxidation of leucomethylene blue (MBH/sub 3//sup 2 +/) by MB/sup +/ (synproportionation) and by Fe(III). Laser flash-photolysis shows that quenching of MB/sup +/(S/sub 1/) by Fe(H/sub 2/O)/sub 6//sup 2 +/ can result in electron transfer to give MBH/sup +/. Profound differences between processes initiated by quenching triplet methylene blue with Fe(H/sub 2/O)/sub 6//sup 2 +/ and with stable coordination complexes of Fe(II) were found. Quenchers included (Fe/sup II/(CN)/sub 6/)/sup 4 -/, (Fe/sup II/(CN)/sub 4/(bpy)/sub 2/)/sup 2 -/, (Fe/sup II/(CN)/sub 2/(bpy))/sup 0/, and (Fe/sup II/(bpy)/sub 3/)/sup 2 +/. Measurements were made in aqueous and aqueous-alcoholic solutions at pH 2, 4.4, and 8.2. Quenching of /sup 3/MBH/sup 2 +/ or /sup 3/MB/sup +/ by a stable complex of Fe(II) is diffusion-controlled and 10/sup 2/ to 10/sup 3/ times the rate at which Fe(H/sub 2/O)/sub 6//sup 2 +/ quenches /sup 3/MBH/sup 2 +/. Net electron transfer accounts for less than 1/3 of total quenching by complexed Fe(II). In contrast, quenching by Fe(H/sub 2/O)/sub 6//sup 2 +/ goes essentially entirely with net electron transfer. It is concluded that quenching of triplet methylene blue by complexes proceeds via electron transfer which is reversible in the encounter complex. The MBH/sup +/ which results from net electron transfer from complexes of Fe(II) decays essentially entirely to MB/sup …

Thermal and hydraulic analyses of the System 81 cold traps

Description: Thermal and hydraulic analyses of the System 81 Type I and II cold traps were completed except for thermal transients analysis. Results are evaluated, discussed, and reported. Analytical models were developed to determine the physical dimensions of the cold traps and to predict the performance. The FFTF cold trap crystallizer performances were simulated using the thermal model. This simulation shows that the analytical model developed predicts reasonably conservative temperatures. Pressure drop and sodium residence time calculations indicate that the present design will meet the requirements specified in the E-Specification. Steady state temperature data for the critical regions were generated to assess the magnitude of the thermal stress.
