Description: The technical and economic attractiveness of combined photovoltaic/thermal (PV/T) solar energy collectors was evaluated. The study was limited to flat-plate collectors since concentrating photovoltaic collectors require active cooling and thus are inherently PV/T collectors, the only decision being whether to use the thermal energy or to dump it. it was also specified at the outset that reduction in required roof area was not to be used as an argument for combining the collection of thermal and electrical energy into one module. Three tests of economic viability were identified, all of which PV/T must pass if it is to be considered a promising alternative: PV/T must prove to be competitive with photovoltaic-only, thermal-only, and side-by-side photovoltaic-plus-thermal collectors and systems. These three tests were applied to systems using low-temperature (unglazed) collectors and to systems using medium-temperature (glazed) collectors in Los Angeles, New York, and Tampa. For photovoltaics, the 1986 DOE cost goals were assumed to have been realized, and for thermal energy collection two technologies were considered: a current technology based on metal and glass, and a future technology based on thin-film plastics. The study showed that for medium-temperature applications PV/T is not an attractive option in any of the locations studied. For low-temperature applications, PV/T appears to be marginally attractive.

Measurement of instantaneous shut-in pressure in crystalline rock

Description: A method is defined which was found useful, not only for determining the instantaneous shut-in pressure (ISIP) during fracture creation, but also for determining the pressure inside the fracture, near the exit and entrance wellbores, when a circulation of fluid through a fracture is taking place. The basic assumption of the Muskat method is that, after a short transient period, the shut-in pressure approaches an asymptotic value, Pa, in an exponential fashion, i.e., if Pa is subtracted from P at each time, t, and the result is plotted, ln (P-Pa) vs t will be a straight line. Various values of Pa are tried until the best straight line fit is found. Two Muskat analyses are shown. (MHR)

Cermets and method for making same

Description: The present invention is directed to a method for making a wide variety of general-purpose cermets and for radioactive waste disposal from ceramic powders prepared from urea-dispersed solutions containing various metal values. The powders are formed into a compact and subjected to a rapid temperature increase in a reducing atmosphere. During this reduction, one or more of the more readily reducible oxides in the compact is reduced to a selected substoichiometric state at a temperature below the eutectic phase for that particular oxide or oxides and then raised to a temperature greater than the eutectic temperature to provide a liquid phase in the compact prior to the reduction of the liquid phase forming oxide to solid metal. This liquid phase forms at a temperature below the melting temperature of the metal and bonds together the remaining particulates in the cermet to form a solid polycrystalline cermet.

A Preliminary Study of the Systemic Problems Underlying U.S.-East European Trade Relations

Description: This study hypothesizes that the major barriers to expanded trade between the U.S. and Eastern Europe are systemic in nature. Using this approach, each political/ economic system is examined in an attempt to define the obstacles to foreign trade expansion, to describe the most important systemic and political factors at work, and to demonstrate how they have determined and will continue to shape the economic relationships between the U.S. and the countries of Eastern Europe. A final synthesis presents the two systems in a unified picture of the economic environment and concludes that significant trade expansion is unlikely in the near future due to basic systemic incompatibilities which impede the resolution of key foreign trade problems.

Important material considerations in INTOR

Description: A number of important material-related problems were identified and analyzed during the Phase-I study for INTOR. The first wall and divertor collector plate are subjected to severe normal and off-normal conditions. A melt layer is predicted to develop in a bare stainless steel wall under plasma disruptions. Graphite tiles will not melt but they introduce other serious uncertainties into the design. The design strategy for the divertor collector plate focused on separating the surface and high heat flux problems and on utilizing a novel mechanical design concept for attaching tungsten tiles to a stainless steel (or copper) heat sink.

Geohydrology of Bandelier Tuff

Description: The Los Alamos National Laboratory has been disposing of radioactive wastes since 1944. Environmental studies and monitoring for radioactive contamination started concurrently. In this report, only two mechanisms and rates by which the radionuclides can enter the environment are studied in detail: subsurface transport of radionuclides by migrating water, and diffusion of tritiated water (HTO) in the vapor phase. The report also includes a section concerning the influence of moisture on shear strength and possible resulting subsidences occurring in the pit overburdens. Because subsurface transport of radionuclides is influenced by the hydraulic conductivity and this in turn is regulated by the moisture content of any given material, a study was also undertaken involving precipitation, the most important climatic element influencing the geohydrology of any given area. Further work is in progress to correlate HTO emanation to atmospheric and pedological properties, especially including thermal characteristics of the tuff.

Interagency Geothermal Coordinating Council fifth annual report. Final draft

Description: Geothermal energy is the natural heat of the earth, and can be tapped as a clean, safe, economical alternative source of energy. Much of the geothermal energy resource is recoverable with current or near-current technology and could make a significant contribution both to increasing domestic energy supplies and to reducing the US dependence on imported oil. Geothermal energy can be used for electric power production, residential and commercial space heating and cooling, industrial process heat, and agricultural process applications. This report describes the progress for fiscal year 1980 (FY80) of the Federal Geothermal Program. It also summarizes the goals, strategy, and plans which form the basis for the FY81 and FY82 program activities and reflects the recent change in national policy affecting Federal research, development and demonstration programs. The Interagency Geothermal Coordinating Council (IGCC) believes that substantial progress can and will be made in the development of geothermal energy. The IGCC goals are: (1) reduce the institutional barriers so that geothermal projects can be on-line in one-half the current time; (2) make moderate temperature resources an economically competitive source of electricity; (3) remove the backlog of noncompetitive lease applications; (4) competitive lease all KGRA lands; and (5) cut the cost of hydrothermal technology by 25%.

Engineering evaluation of the proposed boiler addition for Minnegasco Energy Center, Minneapolis, Minnesota. Final draft report

Description: The results are reported of a technical evaluation of alternate fuels for the proposed oil and natural gas fired No. 3 boiler at the Minnegasco Energy Center (MEC) located in Minneapolis, Minnesota. This report has been prepared for the Department of Energy, Office of Fuels Conversion for their use in considering an alternate fuel exemption petition submitted by MEC. The fuels considered for the proposed boiler include oil, natural gas, bituminous coal, petroleum coke/coal mixture, refuse-derived fuel (RDF), coal-oil mixtures, and coal/oil dual fuel fired. The purchase of steam from the Northern States Power Company (NSPCo) was also considered as an alternative to construction of another boiler at MEC. Evaluation of each fuel included review of the overall plant design, estimates of capital and O and M costs, salvage value, useful life, and quantities of solid waste produced. The MEC supplies steam and chilled water to the downtown Minneapolis area for building heating and cooling using two presently owned and operated 200,000 lb/h oil/natural gas fired boilers. If the proposed boiler is permitted to burn oil and natural gas, it will be identical in design to the existing boilers. The evaluation showed that the use of oil, natural gas, coal, petroleum coke-coal mixtures, coal-oil mixtures, and coal/oil dual fuel firing appear technically feasible as fuel choices for the proposed boiler. The purchase of steam from the NSPCo appears feasible as an alternative to the installation of a new boiler at the MEC. Offsite storage space would be required for receiving and storing coal, petroleum coke, or RDF Offsite fuel preparation facilities are required for preparing petroleum coke-coal mixtures and RDF.

Isotope-dilution mass spectrometry in the measurement of plutonium isotope half-lives

Description: Isotope-dilution mass spectrometry has been used at Los Alamos to measure the half-lives of /sup 239/Pu, /sup 240/Pu, and /sup 241/Pu. The latter was determined by measuring the rate of decrease of the /sup 241/Pu//sup 242/Pu ratio in an appropriate isotopic mixture over a period of several years. The half-lives of the two lighter isotopes are too long to be determined in this manner. They were determined by measuring the rate of production of the uranium daughter relative to a known added /sup 233/U spike. Experimental procedures were designed to control sources of error and to permit a detailed statistical treatment which included all known sources of error and accounted for all covariances. The uncertainties, at the 95% confidence level, associated with the measured half-lives were less than 0.4% for /sup 241/Pu and less than 0.2% for /sup 239/Pu and /sup 240/Pu.

Shear rigidity of spread stearic acid monolayers on water

Description: The effect of Al/sup 3 +/, Fe/sup 3 +/, Ca/sup 2 +/, and Mg/sup 2 +/ ions and of pH on the two-dimensional shear modulus of stearic acid spread on a water substrate was determined. A large shear modulus was displayed by the films when the subphase contained Al/sup 3 +/ and Fe/sup 3 +/ ions at the self buffered pH. With Fe/sup 3 +/ dissolved in the subphase, the film displayed a viscous relaxation when strained but no residual stress was observed. No effect was observed with the Ca/sup 2 +/ or Mg/sup 2 +/. Reducing the pH value in the subphase with the trivalent ions caused the shear modulus to disappear. The observations are interpreted in terms of hydrogen bonding.

Stimulated Raman scattering and four-wave mixing: steady-state plane-wave analytic solutions

Description: The equations for plane-wave steady-state propagation of n fields interacting via four wave processes in a Raman medium have been known since at least 1962. Complete analytic solutions have only been found for the process of harmonic generation. However, solutions have been obtained in the gain regime assuming zero pump depletion. Assuming all fields satisfy the phase matching condition, general analytic solutions to these equations have been found. The solutions are complete in that they describe both pump depletion and saturation. Some example problems will be studied.

Self-focusing in SF/sub 6/

Description: It is shown by explicit calculation of previously published quasicontinuum model that the molecular susceptibility rapidly approaches zero as higher excited states of the molecule become populated. Hence the overtones of the ..nu../sub 3/-pumped mode are totally responsible for the self focusing effects in SF/sub 6/. The ..nu../sub 3/ ladder contribution to the susceptibility is calculated. The vibrational model is a classical triply degenerate anharmonic oscillator in the Cartesian basis with the anharmonicity parameters chosen to be consistent with the latest spectroscopic analysis of the 3..nu../sub 3/ overtone spectrum. The rotational structure is represented by a distribution of these oscillators where the distribution is chosen to correspond to the spectrum of the ..nu../sub 3/ fundamental. Good agreement is found with the 300/sup 0/ in self-focusing data of Nowak and Ham at CO/sub 2/ P(28), P(20) and P(10) in SF/sub 6/.

Preparation of higher-actinide burnup and cross section samples. [LMFBR]

Description: A joint research program involving the United States and the United Kingdom was instigated about four years ago for the purpose of studying burnup of higher actinides using in-core irradiation in the fast reactor at Dounreay, Scotland. Simultaneously, determination of cross sections of a wide variety of higher actinide isotopes was proposed. Coincidental neutron flux and energy spectral measurements were to be made using vanadium encapsulated dosimetry materials in the immediate region of the burnup and cross section samples. The higher actinide samples chosen for the burnup study were /sup 241/Am and /sup 244/Cm in the forms of Am/sub 2/O/sub 3/, Cm/sub 2/O/sub 3/, and Am/sub 6/ Cm(RE)/sub 7/O/sub 21/, where (RE) represents a mixture of lanthanide sesquioxides. It is the purpose of this paper to describe technology development and its application in the preparation of the fuel specimens and the cross section specimens that are being used in this cooperative program.

Contingency Contracting Effects on Psychotherapy Attendance and Termination at Two Community Mental Health Centers

Description: Contingency management has been utilized to improve treatment compliance and attendance in a medical setting. A related question involves the effect of contingency management on attendance in outpatient psychotherapy. Sixty-nine individuals ranging in age from 8 to 50 years agreed to participate in such a study. These individuals agreed to sign a contract specifying consequation for failure to notify the centers 24 hours in advance of an impending absence. Data on attendance and notification of impending absences were collected weekly for five sessions. After five sessions, dropouts and remainers were interviewed and the course of treatment was discussed. For the purpose of this study, a "dropout" occurred whenever an individual terminated therapy by missing an appointment and not rescheduling, or whenever an individual missed three consecutive appointments.
