One-dimensional model calculations of EBT-P performance

Description: Model calculations are described for possible EBT-P designs using a one-dimensional, fluid-transport code. We begin by giving a detailed description of our most updated and complete version of the code itself, so that the appendix is, as far as practical, self-contained. Calculations were performed with the code for the EBT-1 experiment to compare with previous ORNL calculations. One-dimensional calculations for possible EBT-P experimental designs were presented.

Catalyst and process development for hydrogen preparation from future fuel cell feedstocks. Quarterly report July 1-September 30, 1979

Description: Work continued in the effort to develop catalysts and a process for the production of hydrogen from heavier fuels. Progress was made in developing the calculations required to compare the experimental results from the autothermal reforming of No. 2 oil with those predicted by thermodynamic equilibrium. A computer program called ATR-6 facilitates these calculations. A prescreening test is being developed to study steam reforming catalysts under controlled conditions with mixtures of pure compounds. A gas chromatograph was installed and some preliminary runs with ethane were made. A screening test was developed to evaluate steam reforming catalysts under autothermal reforming conditions. During this development work, it was demonstrated that a monolithic CPO catalyst could be started under rich conditions. The catalytic partial oxidation of No. 2 oil produced considerable quantities of olefins (including butadiene) and unreacted oil was also observed. In preliminary runs it was shown that this small test unit was not adiabatic. These early tests also demonstrated that a rhodium containing catalyst is better for steam reforming olefins than a nickel containing catalyst. By adding heat to the reformer section in the amount to compensate for heat losses from this small unit, catalysts could be tested under conditions to be expected from an adiabatic rig. By operating at higher space velocities (about 21,000 V/Hr/Vc) it is possible to distinguish among catalysts during a test lasting 5 to 10 hours.

Energy conservation in two northeastern cities: opportunities, problems, and prospects

Description: Policy assessment of energy conservation strategies has tended to emphasize technological and economic costs, problems, and benefits. However, too narrow a focus may fail to delineate all the environmental and social impacts associated with the technology in question. In recognition of the importance of a balanced evaluation, a study was undertaken to identify local-level perceptions about environmental and social problems and opportunities associated with several energy conservation measures. These measures included building performance standards and retrofit; waste heat utilization; modifications in land use configurations and transportation modes; and electric utility demand management, and rate reform initiatives. The perceptions were identified by interviewing 55 officials, planners, and members of business and citizen groups in Erie, Philadelphia, and Harrisburg (the capital), Pennsylvania. Results of the study indicate that implementation of the energy conservation measures under investigation faces political, economic, and social barriers of varying dimensions. Major among these are the constraints felt to be imposed by a declining economy and the resulting concern with attracting and holding business and industry.

Is it possible to improve the eventrate for narrow resonances in SPEAR and PEP

Description: The eventrate at narrow resonances, like the /psi//J and /Tau/ resonances, is not only determined by the luminosity of the e/sup +/ and e /sup /minus// storage ring but also by the energy spread in the beam due to synchrotron radiation. This energy spread is much larger than the width of the resonances. Therefore, if the energy spread could be reduced by a factor F the eventrate would increase by the same factor.

Energy/material flows associated with cyclic petrochemicals

Description: A detailed product flow analysis, starting with the refinery reformate stream, was prepared to identify the major products of interest. The selection of the products and their derivatives for detailed analysis was based on 1978 consumption data which is reported. The products selected for detailed analysis were: Benzene (from Toluene), Polystyrene, Polyester fibers, Cyclohexane, Nylon 6,6, Nylon 6, ABS + SAN, Phenolic resins, Urethane foams, Unsaturated polyesters and SBR. Data on the selling price of these products and the companies which market these products are tabulated. The production routes were analyzed to determine the key manufacturing processes available. A detailed analysis of the important steps in the production of these materials is presented. For each step in the manaufacturing process a process description, a block flow diagram, the energy consumption, and the feedstock conversions are provided. If more than one process was available and was determined to be commercially important, this route was also presented in detail. If the alternate process was not as significant, then this process was noted and briefly described.

Solar diffusion in California: a pilot study. Consultant report

Description: Solar system owners and their neighbors in the San Francisco Bay Area were studied. The study determined the level of homeowner awareness about residential solar energy systems, described characteristics of consumers purchasing solar equipment (e.g. whether they represent identifiable market segments), identified major channels of communication through which solar information is effectively used, determined remaining barriers to solar use, identified needed incentives to accelerate commercialization, and assessed public attitudes toward various state and Federal government actions to increase the rate of solar energy use statewide. Issues and questions explored are being used in the development of a statewide survey of 700 homeowners in California to determine if these findings apply to residents throughout the state.

User's guide to EPIC, a computer program to calculate the motion of fuel and coolant subsequent to pin failure in an LMFBR

Description: The computer code EPIC models fuel and coolant motion which results from internal fuel pin pressure (from fission gas or fuel vapor) and possibly from the generation of sodium vapor pressure in the coolant channel subsequent to pin failure in a liquid-metal fast breeder reactor. The EPIC model is restricted to conditions where fuel pin geometry is generally preserved and is not intended to treat the total disruption of the pin structure. The modeling includes the ejection of molten fuel from the pin into a coolant channel with any amount of voiding through a clad breach which may be of any length or which may extend with time. One-dimensional Eulerian hydrodynamics is used to treat the motion of fuel and fission gas inside a molten fuel cavity in the fuel pin as well as the mixture of two-phase sodium and fission gas in the coolant channel. Motion of fuel in the coolant channel is tracked with a type of particle-in-cell technique. EPIC is a Fortran-IV program requiring 400K bytes of storage on the IBM 370/195 computer. 21 refs., 2 figs.

Wigglers, beam emittance and energy spread

Description: Wigglers are used in storage rings to increase the beam emittance for maximum luminosity. If, however, a storage ring is used as a synchrotron light source a beam emittance as small as possible is desired. Also in special cases in high energy physics research a large luminosity achieved with wigglers may not be the optimum running configuration. Together with an increase of the beam emittance also the energy spread of the beam is increased. This increase reduces the eventrate for narrow resonances like the /psi/ or /Tau/. In this note we will investigate the conditions for a reduction in beam emittance and/or of the energy spread in the beam.

Determination of PSEUDOGAP state density and carrier mobility in r. f. sputtered amorphous silicon. Quarterly technical progress report, July 1, 1979-September 30, 1979

Description: Apparatus has been designed and assembled to perform field effect measurements using two different sample configurations. Preliminary measurements indicate that the field effect response is smaller than expected in view of the results quoted by other workers on silane-derived a-Si:H and the overall similarity in other opto-electronic properties. Some inconsistency has been observed between nominally identical samples, which may be related either to uncontrolled variables of our deposition process or to some unknown impurities present. Computer programs have been developed to analyze the ray data and derive a density of states versus energy. Using the data obtained so far, we have studied the effect of the assumed potential distribution inside the semiconductor and of the choice of the flat band voltage V/sub FB/ on the derived density of states. The equipment for the measurement of the time of flight drift mobility has been ordered but has not yet arrived.

One and one-half dimensional model of the EBT reactor

Description: A one-dimensional, time-dependent model is described for plasma particle and energy transport and alpha particle transport coupled with magnetic field evolution in a geometry appropriate to EBT. The transport equations used are derived from exact moments of the Boltzmann equation, and the magnetic field is calculated from Faraday's and Ampere's laws. The set of transport equations is closed by incorporating into them transport coefficiencents derived from the appropriate kinetic equation. Also included in the model is a Fokker-Planck calculation of the alpha particle slowing down and resultant plasma heating.

Distribution of illegal incident characteristics: cases of bank fraud and embezzlement, computer-related crime, and insider theft from drug manufacturers and distributors

Description: Three data sets were used to estimate joint and conditional probability distributions between various variables of interest in bank fraud and embezzlement (BF and E) cases of $10,000 dollars or more, computer-related crime cases of various types, and cases of insider theft from drug manufacturers and distributors. This report describes in tabular form the information contained in the three rather extensive data sets from industries facing insider threats which, in one or more dimensions, are analogous to insider threats potentially confronting managers in the nuclear industry. The data in Tables 1 through 29 were computed from the 313 cases of bank fraud and embezzlement (BF and E) representing losses of $10,000 or more reported to the Federal Deposit Insurance Corporation (FDIC) for the period 1977 to 1978. The data in Tables 30 through 64 were computed from the 461 cases of computer-related crime obtained from SRI International for the period 1958 to 1978. These incidents include inventory manipulations designed to hide errors, phony entries used to cover embezzlements, schemes used to penetrate a system and surreptitiously bring about a system crash, and sabotage. The data in Tables 65 through 67 were computed from data reported by the Drug Enforcement Agency (DEA) for the period 1973 to 1978. These data, though limited, provided several interesting insights into the insider-threat problem.

High Temperature Chemistry of Hydrogen Production Cycles

Description: Studies of the catalyzed decomposition of MgSO/sub 4/ were completed and a manuscript describing the work was prepared. ZnSO/sub 4/, ZnO 2ZnSO/sub 4/, CuSO/sub 4/, and Al/sub 2/(SO/sub 4/)/sub 3/ were also found to yield SO/sub 3/ as the sole gaseous decomposition product, although SO/sub 2/ should predominate at equilibrium. As with other metal sulfate decompositions, a distinct progression of observed pressure with effusion orifice area indicates a significant kinetic barrier. Results obtained with the Zn, Cu, and Al sulfates are consistent with the decomposition mechanism postulated for MgSO/sub 4/. For ZnSO/sub 4/ and ZnO 2ZnSO/sub 4/, derived equilibrium pressures indicate that the oxide and basic sulfate reaction products may be formed in a finely divided state of higher surface free energy and slightly lower thermodynamic stability than the normal macrocrystalline phases. None of the semiconducting oxides found to be catalytically effective with MgSO/sub 4/ had any detectable effect on the decomposition of ZnSO/sub 4/ or ZnO 2ZnSO/sub 4/, but Pt had a substantial catalytic effect on the basic sulfate and a moderate effect on ZnSO/sub 4/. A sample of ZnO 2ZnSO/sub 4/(s) was prepared by thermal decomposition of ZnSO/sub 4/ and submitted to Lawrence Livermore Laboratory for measurement of high temperature heat content by drop calorimetry; a second sample has been prepared and submitted for low temperature and solution calorimetry at the Albany Metallurgy Research Center of the Bureau of Mines. With CuSO/sub 4/, the solid phase decomposition product was found to be CuO rather than the CuO CuSO/sub 4/ phase reported in static experiments, and the pressures for moderate to large orifices are converging on the SO/sub 3/ equilibrium pressure when extrapolated to zero orifice size. For the smallest orifice sizes, there appears to be a partial catalysis of SO/sub 3/ to SO/sub 2/ and O/sub 2/ by …
