Conceptual design of a 10MW regenerative isobutane geothermal power plant. Technical report No. 18

Description: At present, there are basically three different systems for converting energy in geothermal fluid into power: vapor-flashing system, total flow system, and binary system. A comparison of the power production processes was made on the basis of work output in Kwh per 1000 pounds of geothermal fluid for self flowing wells with wellhead pressure of 100 psia and for wells with downhole pumps. For simplicity, the assumptions were made that the enthalpy of the geothermal fluid in the reservoir is appr… more

Large area silicon sheet by EFG. Fourth quarterly report, October 1--December 31, 1976

Description: During this reporting period, 5 cm wide ribbons, some with no measurable residual stress, have been grown at speeds up to 5 cm/min. The relationship between residual stress and system vertical temperature gradient was further defined. The problems associated with the purity of the ribbons are being investigated. The influence of light on the recombination characteristics of defects in the ribbons has been investigated. Procedures and results are reported.

Spectra and optics of synchrotron radiation

Description: The spectra, angular distribution, and polarization functions of synchrotron radiation are tabulated in parametric form. Numerous graphs of the functions are included, and these can be used for rapid estimation of photon flux as a function of the various parameters. The extended synchrotron radiation source is described, and the exact, but unintegrable, equations are derived. Properties of this source depend upon at least nine parameters. An approximation of the source accurate enough for estim… more

Temperature Distributions in Electron Beam Welding Cavities

Description: Surface temperatures in electron beam welding cavities in stainless steel 304 and aluminum 1100, 2024, and 6061 were measured with a narrow band infrared radiation pyrometer. A special device was designed for mounting the radiation-sensing probe next to the electron beam gun in the welding chamber. This mounting device included a mechanism for oscillating the probe so as to scan the cavity region both perpendicular and parallel to the welding direction. At the center of its movement the probe v… more

Toxicology and metabolism of nickel compounds. Progress report, December 1, 1975--November 30, 1976. [Tests made with rats and hamsters]

Description: The toxicology and metabolism of nickel compounds (NiCl/sub 2/, Ni/sub 3/S/sub 2/, NiS, Ni powder, and Ni(CO)/sub 4/) were investigated in rats and hamsters. Triethylenetetramine (TETA) and d-penicillamine are more effective than other chelating agents (Na-diethyldithiocarbamate, CaNa/sub 2/-versenate, diglycylhistidine-N-methylamide and ..cap alpha..-lipoic acid) as antidotes for acute Ni(II)-toxicity in rats. The antidotal efficacy of triethylenetetramine (TETA) in acute Ni(II)-toxicity is me… more

Energy and protein production from pulp mill wastes. Progress report, September 15, 1976--December 15, 1976

Description: Significant progress was made during the past quarter in establishing the operability and reliability of major pieces of equipment needed for the production of protein and methane from spent sulfite liquor (SSL). Batch ozonations of SSL were conducted at times varying from 1 to 6 hours at pH's in the range of 10 to 2. These screening experiments consistently indicate that low ph's favor the breakdown of SSL into organic fragments which are more easily assimulated by micro-organisms. Approximate… more

CTR plasma engineering studies. Progress report, 1 September 1975--30 Jun 1976

Description: During the past contract period, this research has been concerned with three principal tasks, namely: (1) Fusion-product studies. The primary objective of this work is to study potential effects (e.g. instabilities, changes in heating profile and wall loadings, etc.) caused by high-energy fusion products. A second objective is to establish the operating conditions and measurements required for use of D-/sup 3/He in early experiments such as TFTR to simulate D-T burns. (2) Mirror system studies.… more

Atmospheric dispersion and noise propagation at Imperial Valley Geothermal Fields

Description: Quantitative estimations are made for the atmospheric dispersion of gases, heat, and noise due to geothermal energy sources in Southern California's Imperial Valley. In particular, gas concentration per unit source strength, change in mixing ratio, relative humidity, temperature, and the ratio of heat flux to solar constant are calculated. The possibility of atmospheric refraction of source noise is also considered.

Inborn anemias in mice. Progress report to accompany twenty-first renewal proposal, 1 May 1975--30 April 1976

Description: Progress is reported on studies on hereditary anemias of mice. At present under study are four macrocytic anemias, four hemolytic anemias, nonhemolytic microcytic anemia, transitory siderocytic anemia, sex-linked iron-transport anemia, and the autoimmune hemolytic anemia of NZB. Each of these blood dyscrasias is caused by the action of a unique mutant gene, each of which determines the structure of different intracellular molecules, and thus controls a different metabolic process. Thus our wide… more

Maximization of energy in the output of a linear system. [LOPAS]

Description: A time-limited signal which, when passed through a linear system, maximizes the total output energy is considered. Previous work has shown that the solution is given by the eigenfunction associated with the maximum eigenvalue in a Hilbert-Schmidt integral equation. Analytical results are available for the case where the transfer function is a low-pass filter. This work is extended by obtaining a numerical solution to the integral equation which allows results for reasonably general transfer fun… more

Final report on a calculational parameter study of soils typical of some ESSEX I cratering sites

Description: The one-dimensional computer calculations described in this report were performed to simulate stress-wave propagation and kinetic energy transfer associated with subsurface cratering detonations in soils. A hypothetical 20-ton-yield nuclear explosive was assumed as the energy source, surrounded by a single soil material. Various soil descriptions were selected in order to systematically study the range of soil response to the nuclear detonation. The soils were representative of the layered mixt… more

Slifers revisited: a method for determining yields independent of radiochemical measurements

Description: It would be very desirable if an independent method other than radiochemical measurement were available to determine the yields of low-yield events in the alluviums and tuffs of areas 2, 9, and 10 at the Nevada Test Site. The successful application of slifers to the measurement of yields from high-yield events suggests that under some conditions they may also be usable with low-yield events. This view is supported by the evidence discussed here, which is based on direct experience with slifer y… more
