90503 mock study. Period covered: October--December 1975

Description: Two billets were pressed from each of three lots of 90503 mock. One billet from each of these lots was pressed using dried powder. Samples were taken from each pressing charge just prior to pressing and volatile content measured. Each of these six billets were then machined into compression and tensile specimens. Additional compression specimens were machined from an existing hemispherical part made from one of these lots of material. Dimensional stability tests were conducted on parts from each billet and the hemisphere. Compression and tensile testing was conducted at 21 C and 49 C on specimens from each of the six billets. The small scale compression specimens from the hemisphere were also tested at these temperatures. The mechanical properties testing shows that the compression strain at rupture and the tensile rupture stress were significantly affected by the higher temperature. No apparent differences were seen between parts made from dried or normal powder.

Ab initio effective potentials for atoms of the first three rows of the periodic table. [Tables, coreless Hartree--Fock effective potential]

Description: The coreless Hartree--Fock effective potential (CHFEP) method is used to replace the core orbitals for atoms of the first three rows of the periodic table. Self-consistent field (SCF) calculations indicate that these effective potentials give Hartree--Fock quality orbitals and orbital energies. Optimized small basis sets for use with these effective potentials are presented along with some tests of these basis sets. It is seen that the effective potential allows one to use such small basis sets without the introduction of any serious error. These smaller basis set calculations allow for great savings in computational time and cost. (auth)

Accurate machining

Description: Very minor test part experience of the all-rotary machine has been obtained. Results at this point appear to verify that the machines (both in the three axis and in the phonograph configuration) are inherently more accurate than machines with slides. Much more work is needed to define the desirable operating parameters and the size capacity of the all rotary machine. A second generation three axis machine is in the design stage which abandons mounting the vertical axes from the top, and instead has three vertical axes at various pin points of link points on a complex tool arm. The part then spins on a fixed axis. This machine is conceived to produce large diameter contoured laser mirrors with great accuracy. Going to a complex set of tool arm linkages greatly reduces the weight and forces on components to be moved during machining, reducing further the very minute deflection in the machining process.

Advanced thermal-energy-storage concept-definition study for solar Brayton power plants. Final technical report, Volume I

Description: The detailed results are presented of a technical and economic assessment of phase change and thermochemical energy storage systems in a solar power plant employing a high temperature Brayton cycle thermal engine with helium as the heat transport fluid. The assessment included an examination of the storage system operation, efficiency, power plant interaction, design, materials, safety, maintenance, environmental impact, system life, and economics. These considerations are implemented in the conceptual design of three baseline storage systems and their components for use in a solar power plant module of 50 megawatt electrical power output. Rationale is provided to support the configuration, operation and material choices. A preliminary assessment of the technology development and experimental test program requirements are also included. The report is contained in four separate volumes. This volume is the technical report.

Air Pollution and the Siting of Fossil Fuel Power Plants

Description: The decision to locate a fossil-fueled electrical power plant on a particular site involves trade-offs among the costs of: (1) land acquisition, (2) plant construction, operation, and maintenance, (3) power transmission, and (4) air pollution damage to humans, animals, plants and materials. The fourth of these, pollution costs, has been of great concern in recent years. But seldom, if ever, are the specific dollar trade-offs between the environmental and the other costs associated with site selection taken into account. The sum of the costs of power generation (land, construction, operation, maintenance), power transmission, and air pollution damages (from sulfur dioxide, nitrogen oxides, and particulates) is the total social cost of a fossil-fuel plant; this total cost will generally vary by site. This paper presents an analysis of the total social cost, and the trade-offs between generation/transmission and air pollution costs, for various types of fossil plants at different sites in northern Illinois. The analysis identifies the combinations of site, fossil fuel, and sulfur dioxide (SO2) control technology that minimize total social costs.

Aluminum limiter experiment in ST tokamak

Description: In order to investigate the effects of a light-element limiter on plasma parameters, aluminum rail limiters interchangeable with Mo rails were installed top, bottom, and outside directions in the ST tokamak. The inside limiter remained a fixed Mo rail. Compared with discharges produced immediately before and after with the usual Mo limiters, the ''aluminum'' discharges showed an increase of T/sub e/ (by factors of 1.4-2 near the center) and of energy confinement (by factors of 2 to 3 in el. energy/power input, depending on time of observation). H/sub 2/ and He discharges showed practically identical effects. In plasma composition, the Mo concentration dropped significantly, but Fe only slightly if at all; the Al concentration was about 3-5 percent (i.e., large compared to the heavier metals), whereas oxygen, about 4 to 8 percent to start with, dropped to insignificance, probably as a result of Al evaporation. The z/sub eff/ from resistivity increased 20-30 percent although the resistance dropped because of the higher T/sub e/. The improved T/sub e/ and energy confinement are thought to be the result of cumulative effects of more favorable radial current and power input distributions rather than direct energy losses by radiation.

Analysis of ''echo sounding'' data North-Central Pacific (including R/V VEMA marine geology/geophysics cruise in the North Pacific). Progress report, July 1, 1975--May 15, 1976. [Geophysical surveys in North Pacific]

Description: Marine geological and geophysical data have been collated and synthesized for the area in the North Pacific bounded by 29/sup 0/N and 31/sup 0/N; 156/sup 0/W and 160/sup 0/W. Particular emphasis has been given to assessing the disposition of the sediment blanket and underlying crystalline basement (layer 2) through the examination of a variety of seismic observations. In July 1975 a 15-day cruise aboard R/V VEMA focused on the collection of a suite of piston cores, heat-flow measurements, high and low frequency seismic profiling, wide angle seismic reflection/refraction using sonobuoys, special near-bottom seismic experiments bathymetric measurements, special heat-transfer experiments, and a variety of complementary marine geological and geophysical observations. The preliminary results of the cruise and their interpretation in the framework of other existing data is summarized.

Analytic solutions for constant tension coil shapes

Description: An analytical solution of the differential equation describing the shape of a flexible filamentary conductor (incapable of supporting bending stresses) in a toroidal magnetic field has been obtained. The solution derives from a series expansion of modified Bessel functions of integer order. The characteristics of toroidal field magnets for proposed tokamak devices are obtainable by term by term integration of the solution series. General expressions are given for the following coil characteristics: the conductor turn length, the solenoid inductance, the area enclosed by the coil and the coil support dimensions. For several particular cases of interest these coil characteristics are obtained as closed form analytical formula. (auth)
