Development and evaluation of elastomeric materials for geothermal applications. Annual report, October 1977-December 1978 (open access)

Development and evaluation of elastomeric materials for geothermal applications. Annual report, October 1977-December 1978

The research involved formulation of commercially available materials and synthesis of new elastomers. Formulation studies at JPL and elsewhere produced a material having about 250-350 psi tensile strength and 30 to 80% elongation at 260/sup 0/C for at least 24 hours in simulated brine. The relationship between these laboratory test results and sealing performance in actual or simulated test conditions is not entirely clear; however, it is believed that no conventional formation or casing packer design is likely to perform well using these materials. The synthetic effort focused on high temperature block copolymers and development of curable polystyrene. Procedures were worked out for synthesizing these new materials. Initial results with heat-cured unfilled polystyrene gum at 260/sup 0/C indicated a tensile strength of about 50 psi. Cast films of the first sample of polyphenyl quinoxaline-polystyrene block copolymer, which has a graft-block structure consisting of a polystyrene chain with pendant polyphenyl quinoxaline groups, showed elastomeric behavior in the required temperature range. Its tensile strength and elongation at 260/sup 0/C were 220 to 350 psi and 18 to 36%, respectively. All of these materials also showed satisfactory hydrolytic stability. A procedure for the synthesis of a linear block copolymer of this type has …

Cryogenic hydrogen data pertinent to magnetic fusion energy (open access)

Cryogenic hydrogen data pertinent to magnetic fusion energy

To aid future hydrogen fusion researchers, I have correlated the measured physical and chemical properties of the hydrogens below 30/sup 0/K. I have further estimated these properties for deuterium--deuterium tritide--tritium (D/sub 2/--DT--T/sub 2/) fusion fuel. My resulting synthesis offers a timely view and review of cryogenic hydrogen properties, plus some hydrogen data to room temperature. My general thrust is for workers new to the field, although my discussion of the scientific background of the material would suit specialists.

Rf power saving in large storage rings (open access)

Rf power saving in large storage rings

This note considers the application of CARTOP, constant amplitude rf to pulse converter, to obtain average and peak power gains in large e/sup + -/ rings. CARTOP is a scheme where energy storage and modulation converts a continuous radio frequency (rf) wave into periodic rf pulses. A system with CARTOP is shown. The modulated rf goes through an energy storing network (ESN) that contains at least one energy storing cavity (ESC), which acts as a flywheel. Between pulses, it takes energy from the klystron and during the pulse it delivers energy to an accelerating cavity (AC).

Fusion Materials Irradiation Test Facility at Hanford (open access)

Fusion Materials Irradiation Test Facility at Hanford

The Fusion Materials Irradiation Test Facility (FMIT) is a high-energy, high-flux neutron source for fusion materials development. The FMIT linear accelerator will produce a 35 MeV beam of deuterons that generates high-energy neutrons by a nuclear stripping reaction with flowing liquid lithium targets. The targets will be located in two identical irradiation test cells, either of which will provide an irradiation volume of 10 cm/sup 3/ at a neutron flux of 10/sup 15/ n/cm/sup 2/-s and 500 cm/sup 3/ at a flux of 10/sup 14/ n/cm/sup 2/-s. FMIT has been authorized by the US Congress and will be constructed and operated by the Hanford Engineering Development Laboratory (HEDL) at Richland, Washington, in collaboration with the Los Alamos Scientific Laboratory (LASL) which is providing the accelerator design. The project is currently entering the detailed design phase, targeting for start of construction in early 1980 and operaion in 1983-84. Research and development programs are underway at both HEDL and LASL to resolve uncertainties in the lithium target and accelerator designs.

Characterization and analysis of Devonian shales as related to release of gaseous hydrocarbons. Well N-1 Henderson County, Illinois and Well N-2 Tazewell County, Illinois (open access)

Characterization and analysis of Devonian shales as related to release of gaseous hydrocarbons. Well N-1 Henderson County, Illinois and Well N-2 Tazewell County, Illinois

Core sampling, hydrocarbon gas contents, chemical and physical characterization data are presented. Core samples from these two Illinois basin wells were obtained in July and August 1977. Thirty-one and twenty-three samples were obtained from N-1 and N-2 wells, respectively, amounting to total core length of 940 feet. Shales from Illinois basin wells (such as N-1 and N-2) are characterized by very low hydrocarbon gas contents. In fact, the N-1 and N-2 wells exhibited the lowest hydrocarbon gas contents among all the wells thus far analyzed. The chemical analysis of these shales also indicates rather low carbon and hydrogen contents, supporting the hydrocarbon gas release data. One significant aspect of the physical characterization data is high porosity associated with low bulk densities. N-1 and N-2 shales exhibit the highest pore volume of any shales from either basin (Appliachian and Illinois). Lithology of these shales does not significantly differ from those of other locations. These shales exhibit relatively low carbonates.

Cool pool development. Quarterly technical report No. 1, April-June 1979 (open access)

Cool pool development. Quarterly technical report No. 1, April-June 1979

The Cool Pool is a passive cooling system consisting of a shaded, evaporating roof pond which thermosiphons cool water into water-filled, metal columns (culvert pipes) located within the building living space. The water in the roof pond is cooled by evaporation, convection and radiation. Because the water in the pool and downcomer is colder and denser than the water in the column a pressure difference is created and the cold water flows from the pool, through the downcomer and into the bottom of the column. The warm column water rises and flows through a connecting pipe into the pool. It is then cooled and the cycle repeats itself. The system requires no pumps. The water column absorbs heat from the building interior primarily by convection and radiation. Since the column is radiating at a significantly lower temperature than the interior walls it plays a double role in human comfort. Not only does it cool the air by convection but it provides a heat sink to which people can radiate. Since thermal radiation is important to the cooling of people, the cold water column contributes substantially to their feelings of comfort. Research on the Cool Pool system includes the following major …

Demonstration of the Environmental Data Corporation Spectral Fuel Conservation System program plan

The purpose of this program is to demonstrate and quantify the amount of fuel that can be saved if the Spectral Fuel Conservation System (SFCS) developed by the Environmental Data Corporation (EDC) is installed in coal-fired industrial boilers. Of central importance to the program are the selection of an appropriate test site and the preparation and methodical application of a comprehensive test strategy. Consequently, the sections dealing with these topics in the proposal have been considerably expanded in this program plan to include as much preparatory thinking as is possible at this early stage. The remainder of this document is essentially an update version of the technical portion of the proposal. No change in the schedule is anticipated.

Stochastic motion of particles in mirror machines (open access)

Stochastic motion of particles in mirror machines

Several applications of stochasticity theory to particle motion in quiescent mirror machines are discussed. We briefly review the problem of magnetic moment jumps in a conventional mirror machine, and point out the role of stochasticity in extending the mirror loss cone. We consider magnetic moment jumps in a flat-bottomed magnetic well, such as the solenoid of a tandem mirror machine, and find that, for suitable choices of field parameters, the magnetic moment change per bounce passes through zero at certain values of energy or pitch angle. This system can be modelled by a simple, asymmetric, two-step map; numerical and analytic studies of the map indicate that phase space can contain stochastic layers, separated by nonstochastic layers that serve as barriers for diffusion. We study the motion of guiding centers in a nonaxisymmetric tandem mirror solenoid and show that ions in the Lawrence Livermore Laboratory Tandem Mirror Experiment (TMX) might be stochastic.

Characterization and analysis of Devonian shales as related to release of gaseous hydrocarbons. Quarterly technical progress report, January-March, 1979

This program has the objective of determining the relationships between the shale characteristics, hydrocarbon gas contents, and well location, and thereby provide a sound basis for (1) assessing the productive capacity of the Eastern Devonian Gas Shale deposits and (2) guiding research, development, and demonstration projects to enhance the recovery of natural gas from the shale deposits. The Y-1 well in Allegany County, New York was sampled in September 1978. 412 samples were collected from the Allegany County, New York well. Characterization data on Y-1 (EGSP New York No. 1), Allegany County, New York well is reported and discussed. Analysis of the hydrocarbon gases in Y-1 samples indicates that the longer chain hydrocarbon gases (ethane, propane, butane) in these shales are significantly higher than in previous wells. The carbon contents of the Y-1 (Allegany County, New York) well, on the other hand, are somewhat lower than predicted from the hydrocarbon gas contents. There is still a positive relationship between the carbon and hydrocarbon gas contents, however. A similar relationship is also apparent between the sulfur and hydrocarbon gas contents. No unusual trends are observed in the porosity values, and a reasonable agreement exists between the measured Hg-intrusion values and those …

Multiheteromacrocycles that complex metal ions. Fifth progress report, 1 May 1978-30 April 1979

The overall objective of this research is to design, synthesize and evaluate cyclic and polycyclic host organic compounds for their abilities to complex and lipophilize guest metal ions, their complexes and clusters. Host organic compounds consist of strategically placed solvating, coordinating and ion-pairing sites tied together by covalent bonds through hydrocarbon units around cavities shaped to be occupied by guest metal ions, or metal ions plus their ligands. Specificity in complexation is sought by matching the following properties of host and guest: cavity and metal ion sizes; geometric arrangements of binding sites; numbers of binding sites; characters of binding sites; and valences. The specific compounds synthesized and their complexing and lipophilizing properties are reported.

Coal feeder survey for Illinois coal gasification group. [Lockhopper, Fuller Kinyon screw, Foster Miller pocket feeder] (open access)

Coal feeder survey for Illinois coal gasification group. [Lockhopper, Fuller Kinyon screw, Foster Miller pocket feeder]

An evaluation of three coal feeder concepts (lockhopper, Fuller Kinyon screw and Foster Miller pocket feeder) for use in the ICGG first stage gasifier was made. For the sake of consistency, all feed concepts were evaluated on the same basis, that is, feeding a nominal 100 Tons per hour (TPH) against a back pressure of 50 psig. Also, all feed systems were assumed to have similar atmospheric storage hoppers and final injection systems. Accordingly, no further consideration of these support systems was made. This survey was accomplished by reviewing the literature, interviewing vendors, contacting applicable facilities and performing necessary original analysis. The emphasis of the survey was on the test and industrial experience of each system. The results of this survey which are summarized on Table I show that the lockhopper system still should be considered as the baseline system because it is a proven system with extensive operating experience. On the other hand, if definitive tests can prove conclusively that the Fuller Kinyon screw pump will deliver coal against 50 psig back pressure with acceptable efficiencies and coal particle attrition characteristics, it would be the preferred system because it is the lowest cost and easiest to maintain.

Is it possible to improve the eventrate for narrow resonances in SPEAR and PEP (open access)

Is it possible to improve the eventrate for narrow resonances in SPEAR and PEP

The eventrate at narrow resonances, like the /psi//J and /Tau/ resonances, is not only determined by the luminosity of the e/sup +/ and e /sup /minus// storage ring but also by the energy spread in the beam due to synchrotron radiation. This energy spread is much larger than the width of the resonances. Therefore, if the energy spread could be reduced by a factor F the eventrate would increase by the same factor.

Actinide cross section data and inertial confinement fusion for long term waste disposal (open access)

Actinide cross section data and inertial confinement fusion for long term waste disposal

Actinide cross section data at thermonuclear neutron energies are needed for the calculation of ICF pellet center burnup of fission reactor waste, viz. 14 MeV neutron fission of the very long-lived actinides that pose storage problems. A major advantage of pellet center burnup is safety: only milligrams of highly toxic and active material need to be present in the fusion chamber, whereas blanket burnup requires the continued presence of tons of actinides in a small volume. The actinide data tables required for Monte Carlo calculations of the burnup of /sup 241/Am and /sup 243/Am are discussed in connection with typical burnup reactor fusion and fission spectra. 2 figures.

A program to design, fabricate, and verify by test a low-cost (in volume production), modularized, practical solar air heater adaptable for new or retrofit space-heating and hot-water applications is described. The unique hardware elements of the SOLAIR II medium-temperature air heater described are the TCA solar collectors, energy transfer module, interconnecting ductwork, and mounting hardware. SOLAIR II is a two-tank domestic hot-water-augmented system. The system is described in detail; market and design analyses are described; fabrication procedures are noted; and design verification tests and results are discussed. The design used for the pre-production lot was essentially the SOLAIR II design and will serve as the basis for future design evaluations as the product is introduced into the commercial market.

The characterization data obtained during the period October through December 1978 are described. One well in Allegany County, New York, was sampled in September 1978. A total of 412 samples were collected from the Allegany County, New York well (165 for Battelle and 247 for other DOE/MERC contractors). Two other wells, namely in Wetzel County, West Virginia and Johnson County, Kentucky, were cored during the last quarter of 1978. A total of 109 samples were obtained from the Wetzel County, West Virginia well (46 samples for Battelle and 63 samples for other DOE/MERC contractors). The samples were obtained from depths of 6100 to 6635 feet. Characterization data on I-2 (EGSP Ind.
