A Non-Gravimetric Method for the Determination of Uranium on Platinum Discs

Description: From abstract: "This paper discusses a method for the determination of uranium on platinum discs which does not involve direct weighing of the deposited film. A statistical analysis of the results obtained indicates that the procedure is more consistent than that based on a gravimetric method and offers a relatively quick and convenient means for obtaining uranium assay results where an accuracy of approximately 99% is desired."

Preliminary Considerations Regarding Stability of MTA Mark I as a Closed-Loop System

Description: The basic scheme under consideration in this research on stability of closed-loop of the Mark I machine is one in which a voltage proportional to the magnitude of the rf fields in the cavity acts to control rectifier voltage output. It is recognized that such is not the only scheme for maximization of output which may be conceived, but only what seems to be a logical and direct way of attaining such an objective.

Physics with polarized beams. Report of the ANL Technical Advisory Panel. [Research with polarized proton beams]

Description: Experimental directions which will be the most useful in developing underlying theories of hadronic collisions are outlined. As a pedagogical device to accomplish this, approximate percentages of a total program which could be devoted to different areas have been quoted. Findings are presented in the form of a short basic report with several long detailed appendices. In the basic report our opinion as to the amount of polarized beam experimental effort that should be applied to the following areas is stated: nucleon-nucleon scattering, quasi-two-body processes, inclusive production, and new or unexplored areas (such as large p/sub T/ and invariance principles). Our reasoning is discussed briefly, however, the details are left for the appendices. Members of the panel present certain aspects of the above areas, which should be useful for planning and/or performing polarized beam experiments. The seven presentations are abstracted separately in ERA.

Effects of CTR irradiation on the mechanical properties of structural materials

Description: Mechanical properties of CTR structural materials are important in determining the reliability and economics of fusion power. Furthermore, these properties are significantly affected by the high neutron flux experienced by components in the regions near the plasma of the fusion reactor. In general, irradiation hardens the material and leads to a reduction in ductility. An exception to this is in some complex engineering alloys where either hardening or softening can be observed depending on the alloy and the irradiation conditions. Regardless of this restriction, irradiation usually leads to a reduction in ductility. Available tensile data examined in this paper show that significant ductility reduction can be found for irradiation conditions typical of CTR operation. Consideration of these effects show that extensive work will be needed to fully establish the in-service properties of CTR structures. This information will be used by designers to develop conditions and design philosophies adapted to avoid the most deleterious conditions and minimize stresses on structures on reactor design. The information will also be used as input to alloy development programs with goals of producing materials more resistant to property degradation during irradiation. It is clear that a great deal of additional work will be required both to understand the effect of CTR irradiation on properties and to develop optimal alloys for this application.

Energy conversion and economics for geothermal power generation at Heber, California, Valles Caldera, New Mexico, and Raft River, Idaho: case studies. Topical report 2

Description: A portion of the results from a one-year study to assess the feasibility of constructing a 25 to 50 MWe geothermal power plant using low-salinity hydrothermal fluids as the energy source is presented. The objective of this report was to investigate the compatibility of the different power conversion options with real geothermal reservoirs and to analyze the economics of power generation. Nine cases are discussed which were chosen to yield further insight into the effect of reservoir temperature on the choice of conversion technology and power costs. These cases examine flashed steam, binary cycle and hybrid conversion for Raft River, Idaho; Heber, California; and Valles Caldera, New Mexico that have bottom-hole temperatures of approximately 150/sup 0/C, 180/sup 0/C and 260/sup 0/C, respectively. Conceptual layouts of the power conversion processes, cycle analyses and economic analyses are presented. The principal conclusions are: a hydrothermal demonstration plant is technically environmentally, and economically feasible in the 1980 time frame; the recommended demonstration site is Heber, Imperial Valley, California; binary cycle power conversion technology is recommended; the recommended demonstration plant capacity is approximately 50 MWe; and there are no overriding environmental constraints.

Methods for analysis of trace elements in coal, coal fly ash, soil, and plant samples. [59 refs]

Description: Results of a literature search are presented, and analytical methods are proposed for studies of trace elements in coal, coal ash residue, soil, and vegetation. Increased trace element levels in soils and plants collected near power plants have been reported by several investigators. Many sample dissolution and analysis techniques were used in the reported studies. A nine-laboratory comparison of trace element analyses for a variety of methods showed excessive variation relative to quoted uncertainty limits. Analysis results from a subsequent four-laboratory comparison of instrumental nuclear techniques for trace element analysis agreed with the National Bureau of Standards certified values for all nine elements determined. Instrumental neutron activation analysis, spark source mass spectrometry, and atomic absorption spectrometry are proposed as primary analysis methods for coal, coal ash, soil, and plants in a Savannah River Laboratory study of trace elements. Bomb procedures are proposed for dissolution of samples.

Summary of radiation-induced transient absorption and recovery in fiber optic waveguides. [Pulsed electrons and x-rays]

Description: The absorption induced in fiber optic waveguides by pulsed electron and X-ray radiation has been measured as a function of optical wavelength from 450 to 950 nm, irradiation temperature from -54 to 71/sup 0/C, and dose from 1 to 500 krads. The fibers studied are Ge-doped silica core fibers (Corning Low Loss), ''pure'' vitreous silica core fibers (Schott, Bell Laboratories, Fiberoptic Cable Corp., and Valtec Fiberoptics), polymethyl-methacrylate core fibers (DuPont CROFON and PFX), and polystyrene core fibers (International Fiber Optics and Polyoptics). Models that have been developed to account for the observed absorption recovery are also summarized.

Determination of permeability of granitic rocks in GT-2 from hydraulic fracturing data

Description: The Los Alamos Scientific Laboratory is currently conducting a study to determine the feasibility to extract geothermal energy from dry hot rock. The investigated concept calls for the creation of a hydraulic fracture in hot, impermeable rock. Heat will be exchanged subsequently at the fracture surface between the rock and a circulating fluid. The successful creation of hydraulic fractures in the granitic section of exploratory holes GT-1 and GT-2 yielded sufficient data to calculate the average permeability of the rock next to a fracture by means of the mathematical model. The calculated permeabilities were found to be in the microdarcy range and proved the granitic rock penetrated by GT-1 and GT-2 to be sufficiently impermeable to test the above concept. (auth)

Design of transonic cascades by conformal transformation of the complex characteristics

Description: A procedure for the numerical design of transonic turbine and compressor blade profiles in two dimensions is considered. In mathematical terms the problem reduces to finding analytic solutions to a system of partial differential equations for flow about a body. The periodicity of the solution results in a cascade. The procedure might be used to design more efficient axial flow compressors for use in the production of enriched uranium at gaseous diffusion plants, as well as in the construction of lighter, more efficient airplane engines for better fuel consumption. 21 figures.

Chemistry of the KALC process. The CO/sub 2/--I/sub 2/--CH/sub 3/I--H/sub 2/O system

Description: The chemistry of the CO/sub 2/--I/sub 2/--CH/sub 3/I--H/sub 2/O system in stainless steel has been investigated with respect to the probable reactions of these components in the KALC process. Iodine is stable in dry CO/sub 2/ contained in stainless steel; but in the presence of organic impurities or water, it is lost from solution via reactions which produce solid phases. Methyl iodide, however, is stable in either wet or dry CO/sub 2/ solutions. Distribution coefficients for I/sub 2/ and CH/sub 3/I between gas and liquid CO/sub 2/ have been measured from -26 to +30/sup 0/C; they show that the solutes favor the liquid phase as the temperature is lowered. The corrosion loss of I/sub 2/ in the presence of 10 to 200 ppm H/sub 2/O has been followed as a function of time at 0 and +21/sup 0/C. Weak associations between CO/sub 2/ and I/sub 2/, CO/sub 2/ and H/sub 2/O, and I/sub 2/ and I/sub 2/ can account for shifts in their respective distribution coefficients, but these associations are not strong enough to produce isolable phases. The occurrence of a weak CO/sub 2/.H/sub 2/O molecular species in the vapor is demonstrated by the near-infrared vibrations of the water group in the species.

Reactive scattering of halogen molecules. [Angular and velocity distributions, stabilities 6. 8 to 17. 7 kcal/mole, FORTRAN]

Description: A study of the endoergic, bimolecular reactions of F/sub 2/ with I/sub 2/, ICl, and HI in a crossed molecular beam experiment is described. The trihalogens IIF, ClIF, and HIF were directly observed as the products of these reactions. At high collision energies a second reactive channel producing IF becomes important. Product angular and velocity distributions show that this IF does not result from a four-center exchange reaction. Measured threshold energies for the formation of IIF, ClIF, and HIF yield lower bounds to the stabilities of these molecules, with respect to the separated atoms, of 69, 81, and 96 kcal/mole, respectively. Analysis of product center-of-mass angular distributions indicates that a slightly nonlinear approach is most effective in bringing about reaction to form the stable triatomic radical. Also described is a crossed molecular beam study of the Cl + Br/sub 2/ ..-->.. BrCl + Br reaction at collision energies from 6.8 to 17.7 kcal/mole. The results indicate that this reaction has the characteristics of an exoergic reaction on an attractive potential energy surface with early energy release. Reagent translational energy is very efficiently channeled into product internal energy. At high collision energy the reaction appears to approach the spectator stripping limit. Finally, a series of computer programs which can be used to carry out the requisite data analysis for crossed molecular beam reactive scattering experiments are described. These programs recover the reactive scattering center-of-mass flux distribution from the measured angular and velocity distributions of the products.

Experimental two-phase liquid-metal magnetohydrodynamic generator program. Annual report. [NaK-nitrogen generator]

Description: A new diverging-channel liquid-metal MHD generator with gas injection along the insulating walls was built and placed in operation in late 1974. This generator yielded nearly-constant liquid velocity along the channel for near-design conditions, as desired for best performance. Extensive measurements of the generator terminal and internal parameters were made over a range of gas and liquid flow rates, magnetic field strengths, and load resistance values. Data are given for generator efficiency and load voltages, and the variations along the channel of liquid and gas velocities, pressure, local load factor, void fraction, and slip ratio. Comparisons are made with theoretical predictions. Tests made to evaluate the effectiveness of the gas injection indicated that the generator performance improved slightly as the amount of gas injected was decreased, and that the injected gas was not forming the desired pure-gas wall layer. Following this, air-water tests indicated that this was to be expected, and a one-dimensional computer model indicated that performance should be better without the partial flow obstruction of the gas injection ports. The gas injection ports were removed, and substantial improvement was obtained in generator performance--by far the best to date. Data comparable to that for gas injection is presented for this case. The future directions of the program, including the role of gas injection, and the modifications to the NaK-nitrogen facility are described.

Radionuclide content of an exhumed canyon vessel and neighboring soil. [Health hazards from long-time buried radiochemical process equipment]

Description: The long-term hazard potential associated with burial of process equipment from radiochemical separations plants is being evaluated. As part of this evaluation, a feed adjustment tank was exhumed eighteen years after burial. The tank had been in service in the fuel reprocessing plant for twenty-nine months before it was retired. Assay of the exhumed tank indicated that 7 mg (0.4 mCi) of /sup 239/Pu and 1 mCi of /sup 137/Cs remained on its surfaces; 1.1 mg (0.07 mCi) /sup 239/Pu, 0.4 mCi /sup 137/Cs, and 3.5 mCi /sup 90/Sr were found in neighboring soil. The vessel and surrounding soil have met the present guidelines (less than or equal to 10 nCi/g) of the U. S. Energy Research and Development Administration (ERDA) for nonretrievable waste.

Surface physics with cold and thermal neutron reflectometry

Description: Three aspects of the research project Surface physics with cold and ultracold neutron reflectometry'' were stressed during the present first year: (1) Setup of the reflectometer facility at the research reactor of the Rhode Island Nuclear Science Center. The installation provides a narrow pencil beam'' analyzed by time of flight using a chopper system. Following beam characterization and a test measurement of the total cross section of copper single crystal first reflectivity measurements are currently performed using a supermirror. (2) Design stud for the ultracold neutron imaging system, with involvement of the relevant industry. Bids are available for several components indicating that it will be very difficult to build the entire system unless further funds become available. (3) Analysis of features of neutron reflection from surfaces with special emphasis on the effect of surface roughness both on the specular beam and the diffusely reflected and refracted intensity. Previous theoretical studies were supplemented by further numerical calculations of diffuse scattering distributions using different models. Application of ultracold and cold neutron reflectometry to the study of liquid-vapor phase transition were discussed. The theoretical work also includes the development of tentative ideas for novel fundamental physics experiments.

Los Alamos Scientific Laboratory building cost index

Description: The Controller's budget request for FY-1979 established guidance for escalation rates at 6 to 8 percent for construction projects beyond FY-1976. The Los Alamos Scientific Laboratory (LASL) has chosen to use an annual construction escalation rate of 10 percent. Results of this study should contribute toward the establishment of realistic construction cost estimate totals and estimates of annual construction funding requirements. Many methods were used to arrive at the LASL escalation rate recommendation. First, a computer program was developed which greatly expanded the number of materials previously analyzed. The program calculated the 1970 to 76 weighted averages for labor, materials, and equipment for the base line project. It also plotted graphs for each category and composite indexes for labor and material/equipment. Second, estimated increases for 1977 were obtained from several sources. The Zia Company provided labor cost estimates. Projected increases for material and equipment were obtained through conversations with vendors and analysis of trade publications. Third, economic forecast reports and the Wall Street Journal were used for source material, narrative, and forecast support. Finally, we compared LASL Building Cost Index with the effects of escalation associated with three recently developed projects at LASL.
