Credit tools to promote energy conservation: a possible federal role
An analysis is presented of the potential of banking institutions to assist in the promotion and implementation of energy conserving measures. Emphasis is given to urban problems and to a possible federal involvement with any measures taken. The relationship between commercial banks and their borrowers was examined. In order to assess a potential federal role, existing regulatory mechanisms were examined. Senior officers of commercial banks were interviewed. A review of relevant literature and federal regulations was undertaken. The fundamentals of lending decisions were reviewed and analyzed in order to develop an understanding of the function of energy considerations in the loan process. The large money-center bank, which satisfies the financial needs of the Fortune 500 borrowers and the city-wide or regional bank, which derives its business from local consumers, are considered.

Interaction of rare gas metastable atoms. [Differential and total cross sections, elastic scattering, ionization, potential scattering, phase shifts, rate constants]
The physical and chemical properties of metastable rare gas atoms are discussed and summarized. This is followed by a detailed examination of the various possible pathways whereby the metastable's excess electronic energy can be dissipated. The phenomenon of chemi-ionization is given special emphasis, and a theoretical treatment based on the use of complex (optical) potential is presented. This is followed by a discussion on the unique advantages offered by elastic differential cross section measurements in the apprehension of the fundamental forces governing the ionization process. The methodology generally adopted to extract information about the interaction potential for scattering data is also systematically outlined. Two widely studied chemi-ionization systems are then closely examined in the light of accurate differential cross section measurements obtained in this work. The first system is He(2/sup 3/S) + Ar for which one can obtain an interaction potential which is in good harmony with the experimental results of other investigators. The validity of using the first-order semiclassical approximation for the phase shifts calculation in the presence of significant opacities is also discussed. The second reaction studied is He*+D/sub 2/ for which measurements were made on both spin states of the metastable helium. A self-consistent interaction potential is …

Fuel performance improvement program. Quarterly/annual progress report, April--September 1977. [BWR; PWR]
The Fuel Performance Improvement Program has as its objective the identification and demonstration of fuel concepts with improved power ramp performance. The program contains a combination of out-of-reactor studies, in-reactor experiments and in-reactor demonstrations. Fuel concepts initially being considered include annular pellets, cladding internally coated with graphite and packed-particle fuels. The performance capability of each concept will be compared to a reference fuel of contemporary pellet design by irradiations in the Halden Boiling Water Reactor. Fuel design and process development is being completed and fuel rod fabrication will begin for the Halden test rods and for the first series of in-reactor demonstrations. The in-reactor demonstrations are being performed in the Big Rock Point reactor to show that the concepts pose no undue risk to commercial operation.

Chemistry and structure of coal-derived asphaltenes, Phase III. Quarterly progress report, July--September 1977
The major benzene insoluble fraction, carboid, solvent-separated from Synthoil coal liquid, was found to be 90 wt.% soluble in pyridine. This fraction, which contains about 50% of the ash present in Synthoil coal liquid, could be 96% de-ashed by dissolution in pyridine. A hypothetical average structure for Synthoil asphaltene has been derived from analytical, VPO MW, x-ray, NMR and chemical functionality data. A self-association model has been developed for calculating molecular weights, and fractions of monomeric, dimeric and trimeric asphaltene species present as a function of concentration in benzene solution. ESR measurements of Lande g-values and spin intensities have been made for coal liquid solvent fractions and asphaltene derived products. The observed g-values fall within the narrow range (2.0028 to 2.0036) previously reported for asphaltic fractions of petroleum and neutral radicals. TGA measurements of coal liquid fractions have been carried out, and % char values determined. Synthoil asphaltene has been found to undergo oxygen induced reactions which stabilize it toward volatilization vis-a-vis the Synthoil carboid fraction. Silylation studies on carboid coal-liquid fractions afforded % OH/Q/sub total/ values: Synthoil, 47; HRI H-Coal, 64; FMC-COED, 52; Catalytic Inc., 36; PAMCO, 53. Methylation studies of Synthoil asphaltene, with methyl iodide, indicate that about …

Geothermal Reservoir Well Stimulation Project: reservoir selection task
The Geothermal Reservoir Well Stimulation Project has prepared a two-year program to develop and field test methods of stimulating geothermal wells. The program provides for six field experiments which progress in difficulty from low temperature reservoirs using current technology to high temperature reservoirs using advanced types of stimulation treatments. The process used to select the six field experiment locations and stimulation treatments is described. Tentatively, the following reservoirs are proposed: Raft River, East Mesa, Baca and Westmorland (two experiments), and Brawley and The Geysers or Roosevelt Hot Springs (two experiments). The program will be reviewed after each field treatment to select a specific well candidate for the next experiment and to determine whether alteration of the sequence will be beneficial to the overall success of the project and the geothermal industry.

Neutron diagnostics for laser fusion experiments
Three different neutron diagnostic instruments are used at our laboratory to acquire data for judging the performance of D-T filled laser-fusion targets. Large scintillation detectors and a neutron activation system are used to measure the number of 14-MeV reaction neutrons emitted from a target, and a 45-meter neutron time-of-flight spectrometer is used to determine the fuel ion temperature. At our facilities, the scintillation detectors are used for neutron yields above 10/sup 4/ per shot, and neutron activation by the /sup 63/Cu(n,2n)/sup 62/Cu reaction is used as an additional diagnostic device for yields above 10/sup 8/ per shot. Application of these techniques to laser-fusion measurements data taken at the Argus laser facility, and neutron diagnostics being prepared for the Shiva facility are discussed. Comparison of experimental yield data obtained for a number of laser-fusion targets show that neutron yield values obtained by the neutron systems and ..cap alpha..-particle yields by TOF methods are in good agreement.

Determination of nitrogen in boron carbide with the Leco UO-14 Nitrogen Determinator
Use of various metals as fluxes for releasing nitrogen from boron carbide in the Leco Nitrogen Determinator was investigated. Metals such as iron, chromium, and molybdenum that wet the graphite crucible all promoted nitrogen release. Tin, copper, aluminum, and platinum did not wet the graphite and were of no value as fluxes. A procedure for sample handling and the resulting performance of the method are described. The precision at 0.06 to 0.6 percent nitrogen averaged 4 percent relative standard deviation.

Status report: waste incineration and fixation for Waste Management, Production, and Reprocessing Division of the Department of Energy (July--December 1976)
Fluidized bed incineration and waste fixation processes are being used to process the types of wastes expected from nuclear fuel reprocessing and production plants. Test incineration runs have been made on two types of wastes: high efficiency particulate air (HEPA) filters and tributyl phosphate-solvent solutions. Laboratory-scale vitrification equipment was used to produce glass pellets from incinerator ash and blends of other expected waste streams. Computer modeling gave an expected product integrity life of over 2,000 years.

PADLOC: a one-dimensional computer program for calculating coolant and plateout fission product concentrations. [HTGR]
The one-dimensional computer program PADLOC is designed to analyze steady-state and time-dependent plateout of fission products in an arbitrary network of pipes. The problem solved is one of mass transport of impurities in a fluid, including the effects of sources in the fluid and in the plateout surfaces, convection along the flow paths, decay, adsorption on surfaces (plateout), and desorption from surfaces. These phenomena are governed by a system of coupled, nonlinear partial differential equations. The solution is achieved by (a) linearizing the equations about an approximate solution, employing a Newton Raphson iteration technique, (b) employing a finite difference solution method with an implicit time integration, and (c) employing a substructuring technique to logically organize the systems of equations for an arbitrary flow network.

Systems study for initial development of a laboratory records information system
The major impetus for a system study of the ORNL Laboratory Records Department (LRD) was the ORNL-3300, a computer listing of all ORNL reports, papers, and oral presentations. Although this file has been maintained by the Information Division Libraries Department (LD) for several years, the usability of the file is somewhat limited, and duplicative steps appear to be involved in generation of the file. In order to examine procedures involved in generating the ORNL-3300, along with other Library Department and Laboratory Records Department procedures, various Information Division personnel were interviewed and the LRD Procedures Manual was reviewed. The existing LRD and LD procedures surrounding the ORNL-3300 were examined closely with the intent of developing an LRD computer data base from which the ORNL-3300 would be a by-product and which would eliminate duplicative manual procedures whenever possible. Integrating the ORNL-3300 into a computer data base system would allow Boolean logic searches on the 3300 data not possible with the present system. No attempt was made to examine ORNL-3300 facsimile data bases maintained by various divisions, although several are known to exist. Although addressing the ORNL-3300 is the major thrust of this paper, development of computer data bases for foreign visitors and …

Turbulent diffusion of small particles
The diffusion of small, spherical, rigid particles suspended in an incompressible turbulent fluid, but not interacting with each other, was studied. As a stochastic process, the turbulent fluid velocity field is assumed to be homogeneous, isotropic and stationary. Assuming the Stokes regime, a particle of equation of motion is used which includes only the effects of Stokes drag and a virtual mass force and an exact solution is found for the particle velocity correlation function, for all times and initial conditions, in terms of a fluid velocity correlation function measured along the motion of the particle. This shows that for times larger than a certain time scale, the particle velocity correlation becomes stationary. The effect of small shears in the fluid velocity was considered, under the additional restrictions of a certain high frequency regime for the turbulence. The shears convected past the particle much faster than the growth of the boundary layer. New force terms due to the presence of such shears are calculated and incorporated into the equation of motion. A perturbation solution to this equation is constructed, and the resultant particle velocity correlation function and diffusion coefficient are calculated. To lowest order, the particle diffusivity is found to …

RAFT: a computer program for fault tree risk calculations. [In FORTRAN for CDC Cyber 74-18]
A description and user instructions are presented for RAFT, a FORTRAN computer code for calculation of a risk measure for fault tree cut sets. RAFT calculates release quantities and a risk measure based on the product of probability and release quantity for cut sets of fault trees modeling the accidental release of radioactive material from a nuclear fuel cycle facility. Cut sets and their probabilities are supplied as input to RAFT from an external fault tree analysis code. Using the total inventory available of radioactive material, along with release fractions for each event in a cut set, the release terms are calculated for each cut set. Each release term is multiplied by the cut set probability to yield the cut set risk measure. RAFT orders the dominant cut sets on the risk measure. The total risk measure of processed cut sets and their fractional contributions are supplied as output. Input options are available to eliminate redundant cut sets, apply threshold values on cut set probability and risk, and control the total number of cut sets output. Hash addressing is used to remove redundant cut sets from the analysis. Computer hardware and software restrictions are given along with a sample problem …

Study of Electron and UV Photon Surface Interactions. Progress Report, March 1, 1977--February 28, 1978
Considerable data on ESD from 304 stainless steel have been obtained. Cross sections as a function of bombarding electron energy, surface temperature, desorbing species, etc. are now available. Energy distributions of desorbing ions have also been tabulated. It is interesting to note that regardless of sample material and sample preparation H/sup +/ and F/sup +/ were always predominant ESD species. Electron induced dissociation of metal oxides, noted during AES measurements, has been studied for a variety of materials including oxides of molybdenum, niobium and tungsten. Photodesorption is detected from niobium and is related to the thick niobium oxide surface layer. CO/sub 2/ is again the dominant desorbing species. Ion impact desorption studies have begun and both positive and negative desorbing ions have been detected. Preliminary simultaneous electron and ion bombardment measurements indicate definite but quite complex synergistic effects. The critical reviews on ESD and photodesorption have been updated and accepted for publication.

Avalanche localization and its effects in proportional counters
Avalanche development around the anode wire in a gas proportional counter is investigated. In the region of proportional gas amplification, the avalanche is found to be well localized on one side of the anode wire, where the electrons arrive along the field lines from the point of primary ionization. Induced signals on electrodes surrounding the anode wire are used to measure the azimuthal position of the avalanche on the anode wire. Practical applications of the phenomena such as left-right assignment in drift chambers and measurement of the angular direction of the primary ionization electrons drifting towards the anode wire are discussed.
