Temperature tests of high frequency SLIFER oscillator, LEA73-2176. [For monitoring underground nuclear detonations at Nevada Test Site]
SLIFER (Short Location Indication by Frequency of Electrical Resonance) systems measure stress wave velocity in solid or liquid materials. They monitor underground nuclear detonations at the Nevada Test Site (NTS). A shorted length of coaxial cable is a component in an oscillator's tank circuit. This sensor cable is inductive when less than one-fourth wavelength long at the oscillator's resonant frequency. The stress wave from a detonation crushes and shorts this sensor cable. As the short proceeds, inductance decreases and oscillator frequency increases. Later we convert frequency vs time to shock-front position vs time. Some doubt existed about the reliable operation of the oscillators in cold weather. Therefore these tests were conducted to check their reliability under several conditions: (1) at temperatures from -40/sup 0/ to 60/sup 0/C; (2) with three sensor cable lengths; (3) with sensor cables shorted or open at the far end; and (4) at two input power voltages. Results are presented.

Prototype gauge for measuring contour and wall thicknesses of hemispherical parts. [Interferometer]
A prototype gauge (gage) was designed and fabricated using air bearings in a new configuration to provide less error and distortion during inspection of hemispherical parts. No wear occurs on the moving parts during operations and accuracy of alignment is maintained. The gauge will check outside radial distance, inside radial, and outside radial and wall, and inner radial and wall thicknesses of parts. The gauge contains only four moving parts, which increases the measuring accuracy. A horizontal table rotates. A table mounted on the horizontal table at 45/sup 0/ rotates through two transducers. All moving parts are mounted on hydrostatic gas bearings. Laser interferometric, air-bearing gauge heads are used to obtain the required data. Investigation of a hemispherical part is in any desired spiral path from equator to pole. Measurement information is obtained from two laser interferometric transducers using linear air bearings. The transducers use a Spectra Physics Model-120 helium and neon laser. Working range of each transducer is 1.5 inches. The fringe voltage signals are amplified and converted to inches to be displayed on a digital readout. A punched paper tape contains the nominal inside diameter (ID) and outside diameter (OD) information in Binary Coded Decimal form. The tape …

Comparison of the Personalities of Non-Injured and Injured Female Athletes in Intercollegiate Competition
This study was designed to determine if differences exist between the personalities of injured and non-injured athletes, injured and non-injured athletes in individual sports, and injured and non-injured athletes in team sports. Subjects were forty-three female athletes selected from six intercollegiate teams. The test instrument was the Cattell Sixteen Personality Factor Questionnaire. Data were analyzed by the two-way analysis of variance. Alpha was .05. Conclusions of the investigation were that the personality of injured athletes does not differ from the personality of non-injured athletes, that non-injured athletes in individual sports are more self-assured than non-injured athletes in team sports, and that the personality of athletes in team sports does not differ from the personality of athletes in individual sports.

Rankine cycle energy conversion system design considerations for low and intermediate temperature sensible heat sources. Geothermal, waste heat, and solar thermal conversion
Design considerations are described for energy conversion systems for low and intermediate temperature sensible heat sources such as found in geothermal, waste heat, and solar-thermal applications. It is concluded that the most cost effective designs for the applications studied did not require the most efficient thermodynamic cycle, but that the efficiency of the energy conversion hardware can be a key factor.

Heat Extraction from a Hydraulically Fractured Penny-Shaped Crack in Hot Dry Rock
Heat extraction from a penny-shaped crack having both inlet and outlet holes is investigated analytically by considering the hydraulic and thermal growth of the crack when fluid is injected at a constant flow rate. The rock mass is assumed to be infinitely extended, homogeneous, and isotropic. The equations for fluid flow are derived and solved to determine the flow pattern in the crack. Temperature distributions in both rock and fluid are also determined. The crack width change due to thermal contraction and the corresponding flow rate increase are discussed. Some numerical calculations of outlet temperature, thermal power extraction, and crack opening displacement due to thermal contraction of rocks are presented for cracks after they attain stationary states for given inlet flow rate and outlet suction pressure. The present paper is a further development of the previous works of Bodvarsson (1969), Gringarten et al. (1975), Lowell (1976), Harlow and Pracht (1972), McFarland (1975), among others, and considers the two-dimensional rather than the one-dimensional crack. Furthermore, the crack radius and width are quantities to be determined rather than given a priori. 11 refs., 1 tab., 5 figs.

Model for the prediction of the pressure-volume relationship of porous rocks
Several models have been suggested to describe the volume behavior of porous materials under hydrostatic loading. The model presented here accounts for variations in both porosity and the amount of fluid contained within that porosity. The model also attempts to predict the one-dimensional strain loading pressure-volume relationship and the stress difference-confining pressure curve. Only the simplest assumptions were used for the development of this model. These assumptions are discussed and the predictions for Mt. Helen tuff are compared to experimental data.

Diffusion of gases in solids: rare gas diffusion in solids; tritium diffusion in fission and fusion reactor metals. Final report
Major results of tritium and rare gas diffusion research conducted under the contract are summarized. The materials studied were austenitic stainless steels, Zircaloy, and niobium. In all three of the metal systems investigated, tritium release rates were found to be inhibited by surface oxide films. The effective diffusion coefficients that control tritium release from surface films on Zircaloy and niobium were determined to be eight to ten orders of magnitude lower than the bulk diffusion coefficients. A rapid component of diffusion due to grain boundaries was identified in stainless steels. The grain boundary diffusion coefficient was determined to be about six orders of magnitude greater than the bulk diffusion coefficient for tritium in stainless steel. In Zircaloy clad fuel pins, the permeation rate of tritium through the cladding is rate-limited by the extremely slow diffusion rate in the surface films. Tritium diffusion rates through surface oxide films on niobium appear to be controlled by cracks in the surface films at temperatures up to 600/sup 0/C. Beyond 600/sup 0/C, the cracks appear to heal, thereby increasing the activation energy for diffusion through the oxide film. The steady-state diffusion of tritium in a fusion reactor blanket has been evaluated in order to …

Neutron-induced mutation experiments. Progress report, March 1, 1976--February 28, 1977. [In Drosophila]
Results are from studies of experiments in Drosophila on the relative mutagenic effectiveness of neutrons of different energies employing X-linked recessive lethal and specific locus mutation tests. The energies and doses employed to data are .43 MeV (500, 1000, and 1500 R, in progress), .68 MeV (250, 500, 1000, and 1500 R), 2 and 6 MeV (250 and 500 R), and 15 MeV (250, 500, 1000, 1500 and 3000 R). .68 MeV neutrons appear to have an RBE between 3.3 to 4.5, 15 MeV neutrons an RBE between 1.9 to 2.2, and 2 and 6 MeV neutrons RBE's of intermediate values. The data for both .68 and 15 MeV neutrons do not yet differentiate between a linear and quadratic dose/frequency response curve for the doses studied. The specific locus mutation data also indicate the highest RBE for .68 MeV, followed by 2 and 6 MeV respectively.

Genetic effects of low x-ray doses. Progress report, October 1, 1975--September 30, 1976. [Drosophila oogonia]
Experiments on dose-kinetics of x-ray induced sexlinked lethal mutations in Drosophila oogonia were continued. A wide range of doses was tested, with special emphasis on the low-dose range (20 to 500R). This year more data were added for O R, 200, 500, 1500R and some high doses. Oogonia of adult females were irradiated, and only one daughter from each experimental parent-female was analyzed for a new lethal in her maternal X-chromosome. Thus no clusters of mutations of identical origin are encountered. The extensive accumulated data do not support the linearity principle, firmly established for recessive mutations induced in mature spermatozoa for high doses down to very low x-ray doses. A mathematical model describing the mutational yield is included that suggests that recessive mutations, like chromosome aberrations, result from both one-track and two-track events, with the latter playing an increasingly important role at higher doses.

Diphenyloxazole Metabolism by Aryl Hydrocarbon Hydroxylase
2,5-Diphenyloxazole (PPO) was tested as a potential alternate inducer for the aryl hydrocarbon hydroxylase (AHH) system. Its apparent lack. of carcinogenicity and toxicity provide a possible system for investigation of enzyme systems related to chemical carcinogenesis without exposure of the researcher to potent carcinogenic compounds. These studies found PPO to be an inducer of AHH in cultured human lymphocytes. When PPO was utilized as a substrate for the AHH assay system, the major metabolites produced were strongly fluorescent. A simple fluorometric assay was developed which employed PPO as the substrate and which measured constitutive activity more efficiently than similar assays using benzo(a)pyrene as the substrate. Quantitation of both basal and induced lymphocyte AHH metabolism of PPO may be applicable to human population studies and may provide a tool to determine possible genetic variables with respect to carcinogen metabolism related to cancer risk.

Heat transfer in tube bundles of heat exchangers with flow baffles induced forced mixing
Thermal analysis of shell-and-tube heat exchangers is being investigated through geometric modeling of the unit configuration in addition to considering the heat transfer processes taking place within the tube bundle. The governing equations that characterize the heat transfer from the shell side fluid to the tube side fluid across the heat transfer tubewalls are indicated. The equations account for the heat transfer due to molecular conduction, turbulent thermal diffusion, and forced fluid mixing among various shell side fluid channels. The analysis, though general in principle, is being applied to the Clinch River Breeder Reactor Plant-Intermediate Heat Exchanger, which utilizes flow baffles appropriately designed for induced forced fluid mixing in the tube bundle. The results of the analysis are presented in terms of the fluid and tube wall temperature distributions of a non-baffled and baffled tube bundle geometry. The former case yields axial flow in the main bundle region while the latter is associated with axial/cross flow in the bundle. The radial components of the axial/cross flow yield the necessary fluid mixing that results in reducing the thermal unbalance among the heat transfer to the allowable limits. The effect of flow maldistribution, present on the tube or shell sides of the …
