SPE water electrolysis technology development for large scale hydrogen production. Progress report No. 4, June 15, 1976--September 30, 1976 (open access)

SPE water electrolysis technology development for large scale hydrogen production. Progress report No. 4, June 15, 1976--September 30, 1976

Porous carbon fiber paper was selected as the cathode membrane and electrode assembly support based on over 1200 hr operational evaluation. Three potential anode supports are under test. All three appear technically satisfactory after 500 to 1200 hr operational evaluation on each. Optimization of molds and molding techniques for a foil backed ribbed carbon collector of bipolar design, including ribbed flow fields, manifolds, ports and sealing surfaces, is in process. Over 2800 hr demonstrated at 300/sup 0/F on platinum screened cell. Over 2200 hr demonstrated at 300/sup 0/F on cell with carbon cloth cathode current collector. Forty-eight hours screening tests of 56 different anode catalysts have been completed. A 500-hr life test program of 12 anode catalyst types which showed promise on the screening tests has been started. Attempts to stabilize RuO/sub x/ for use as an anode catalyst are being pursued. Low loaded cathodes on graphite substrates show performance to within 25 MV of baseline. Optimization of substrate thickness and fabrication procedures is continuing. Twenty-five low loaded anodes catalyst/substrate combinations have all shown poor performance stability with time. Continued development of the grafted TFS membrane has shown greatly improved physical characteristics and encouraging performance for samples in the 25 …

Accurate machining (open access)

Accurate machining

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.

TFTR ultrahigh-vacuum pumping system incorporating mercury diffusion pumps (open access)

TFTR ultrahigh-vacuum pumping system incorporating mercury diffusion pumps

The TFTR vacuum vessel will have a system of four 61 cm diameter mercury diffusion pumps to provide a base pressure in the 10/sup -8/ to 10/sup -9/ Torr range as well as a low impurity level within the vessel. The system, called the Torus Vacuum Pumping System (TVPS), will be employed with the aid of an occasional 250/sup 0/C bakeout in situ as well as periodic applications of aggressive discharge cleaning. The TVPS is an ultrahigh-vacuum (UHV) system using no elastomers as well as being a closed system with respect to tritium or any tritiated gases. The backing system employing approximately 75 all-metal isolation valves is designed with the features of redundancy and flexibility employed in a variety of ways to meet the fundamental requirements and functions enumerated for the TVPS. Since the design, is one which is a modification of the conceptual design of the TVPS, those features which have changed are discussed. Calculations are presented for the major performance parameters anticipated for the TVPS and include conductances, effective pumping speeds, base pressures, operating parameters, getter pump parameters, and calculations of time constants associated with leak checking. Modifications in the vacuum pumping system for the guard regions on …

Load relaxation studies of zircaloy-4 (open access)

Load relaxation studies of zircaloy-4

The results of the present work have shown (1) the load relaxation data of Zircaloy-4 in the temperature range of 200/sup 0/C to 385/sup 0/C can be represented by the phenomenological model based on Hart's plastic equation of state; (2) the room temperature load relaxation data reflect the effects of deformation twinning; (3) at higher temperatures the load relaxation data suggest the contribution of grain boundary sliding; and (4) the effects of strain aging can be identified based on the load relaxation data.

Conditioning of the vacuum vessel walls of tokamaks, a preliminary look (open access)

Conditioning of the vacuum vessel walls of tokamaks, a preliminary look

The main features and operating characteristics of the primary vacuum system of many of the presently operating tokamak devices are presented. Particular attention is paid to the methods used to condition and clean the vessel walls in situ. For the devices discussed, a combination of a high-temperature bakeout and/or discharge cleaning is employed. In addition, discussions of the vacuum systems and wall conditioning methods anticipated for the next generation of tokamaks are presented. Since this report was written during a limited time period, it should be considered as preliminary and is not intended to be a general review. Much of the information that is presented was obtained by private communication and there is no bibliography. This study was initiated to aid in the design of TFTR. As presently envisioned, the TFTR vacuum system and methods for wall conditioning are consistent with what is presently practiced.

Hydrogeologic impact analysis of new water uses in Section 7, T. 10 N. , R. 28 EWM. , of the Hanford Reservation (open access)

Hydrogeologic impact analysis of new water uses in Section 7, T. 10 N. , R. 28 EWM. , of the Hanford Reservation

An evaluation was made of the hydrologic impact upon the Hanford ground water regime of removing 1.7 million gallons per day, MGD (6.4 million liters per day, MLD) from the unconfined aquifer in the north half of Section 7, T. 10 N., R. 28 EWM., and recharging to the aquifer within the same area 1.0 MGD (3.8 MLD). The hydrogeology of the specific area was characterized by examining data obtained from nearby wells. A preliminary well yield analysis was performed which verified that one well could supply 6.4 MLD at the study site. Several reasonable, simplifying assumptions were made which permitted the determination by means of an analytical equation of the water table changes resulting from projected water uses. The results of the analysis show minimal impact upon the water table as a result of either the withdrawal or recharge of water. The estimated size of a pond for recharging the used water would be about three to six acres. If the proposed groundwater use activity is implemented, one step-drawdown and one pump test are recommended to verify the withdrawal well water yield.

Conceptual design study on incorporating a 25-ton/day pyrolysis unit into an operating total energy system. Final report (open access)

Conceptual design study on incorporating a 25-ton/day pyrolysis unit into an operating total energy system. Final report

The results of a conceptual design study on incorporating a pyrolysis unit into an existing total energy plant are presented. The objectives of this study were to examine the institutional, technical and economic factors affecting the incorporation of a 25-ton/day pyrolysis unit into the Indian Creek Total Energy Plant. The Indian Creek total energy plant is described. Results of the conceptual design are presented. A survey of the availability of waste materials and a review of health and safety ordinances are included. The technical aspects of the pyrolysis system are discussed, including the results of the review of facilities requirements for the pyrolysis unit, the analysis of necessary system modification, and an estimate of the useful energy contribution by the pyrolysis unit. Results of the life-cycle cost analysis of the pyrolysis unit are presented. The major conclusions are that: there appears to be no institutional or technical barriers to constructing a waste pyrolysis unit at the Indian Creek Total Energy Plant; pyrolysis gas can be consumed in the engines and the boilers by utilizing venturi mixing devices; the engines can consume only 5% of the output of the 25-ton/day pyrolysis unit; Therefore, consumption of pyrolysis gas will be controlled by …

Acoustic emission from beryllium (open access)

Acoustic emission from beryllium

The acoustic emission from both powder and ingot source beryllium has been measured as a function of strain and prior heat treatment. Most measurements were made during tensile deformation, but a limited number of compression tests have also been performed. The acoustic emission observed was of the burst type, with little or no contribution from continuous type emission. The emission was characterized by the variation of burst rate and average energy per burst as a function of strain. The tensile behavior was qualitatively similar for all the materials tested. Burst rate maxima centered roughly at 0.1 percent and 1.0 percent plastic strain were observed. The magnitude but not the strain at the low strain burst rate peak was very sensitive to prior thermal treatment, while the higher strain burst rate peak was insensitive to prior heat treatment. An energy per burst maximum was observed at 0.2 percent plastic strain, the magnitude of which was moderately sensitive to heat treatment. The Kaiser effect is observed in the material studied. Emission during compression was similar to that observed in tension. The acoustic emission observed is attributed to dislocation motion, as proposed by James and Carpenter for LiF, NaCl, and Zn.

Evaluation of carbon monoxide in blood samples from the second health and nutrition survey. Progress report No. 1 (open access)

Evaluation of carbon monoxide in blood samples from the second health and nutrition survey. Progress report No. 1

This is a study of carbon monoxide (CO) in the blood of human subjects participating in the Second National Health and Nutrition Survey (HANES II), a detailed study of health indicators in sample populations of many communities throughout the U.S. The purpose of this aspect of the survey is to evaluate the levels of blood carboxyhemoglobin in normal individuals of all ages in typical U.S. communities, from whom accurate histories and clinical studies are available. This report gives results of the first of three years of analyses. A careful calibration of the analytical method has been completed, and more than 3000 blood samples have been analyzed. Although smoking histories are not yet available to permit evaluation of carboxyhemoglobin in non-smokers, in children under 12 years of age, blood COHb has been found to be consistently low, with less than 3% greater than 1.5% COHb. These preliminary results suggest that urban exposure to carbon monoxide among the general population is not now significant in the U.S., at least during the period of these early examinations.

Regional transport model of atmospheric sulfates (open access)

Regional transport model of atmospheric sulfates

A regional transport model of atmospheric sulfates was developed. This quasi-Lagrangian three-dimensional grid numerical model uses a detailed SO/sub 2/ emission inventory of major anthropogenic sources in the eastern U.S. region and observed meteorological data during an episode as inputs. The model accounts for advective transport and turbulent diffusion of the pollutants. The chemical transformation of SO/sub 2/ and SO/sub 4//sup 2 -/ and the deposition of the species at the earth's surface are assumed to be linear processes at specified constant rates. The numerical model can predict the daily average concentrations of SO/sub 2/ and SO/sub 4//sup 2 -/ at all receptor locations in the grid region during the episode. Because of the spatial resolution of the grid, this model is particularly suited to investigate the effect of tall stacks in reducing the ambient concentration levels of sulfur pollutants. The formulations and assumptions of the regional sulfate transport model are presented. The model inputs and results are discussed. Isopleths of predicted SO/sub 2/ and SO/sub 4//sup 2 -/ concentrations are compared with the observed ground level values.

Instrumentation and process control development for in situ coal gasification. Fourth quarterly report, September--November 1975 (open access)

Instrumentation and process control development for in situ coal gasification. Fourth quarterly report, September--November 1975

The instrumentation effort for Phases 2 and 3 of the Second Hanna In Situ Coal Gasification Experiment was fielded and background data obtained prior to the initiation of Phase 2 on November 25, 1975. A total of over 600 channels of instrumentation in 15 instrumentation wells and two surface arrays was fielded for the instrumentation techniques under evaluation. The feasibility of the passive acoustic technique to locate the source of process-related noises has been demonstrated; its utility is presently hampered by the inexact definition of signal arrivals and the lack of automated signal monitoring and analysis systems. A revised mathematical model for the electrical techniques has been developed which demonstrates the potential for remote monitoring. (auth)

Geochemistry and hydrothermal alteration at selected Utah hot springs. Final report: Volume 3 (revised) (open access)

Geochemistry and hydrothermal alteration at selected Utah hot springs. Final report: Volume 3 (revised)

Application of Na-K-Ca geothermometry to warm springs in Utah indicates several areas with sufficiently high apparent temperatures to be of interest as geothermal exploration targets. A zone of warm springs in the Bonneville Basin show Na-K-Ca temperatures from 150/sup 0/C to 233/sup 0/C. Examination of Great Salt Lake, Bonneville sediment pore water, and Jordan Valley well-water chemistry indicates that mixing a small percent of these fluids with warm spring water can cause substantial errors in Na-K-Ca temperature estimates. Other saline deposits which may influence Na-K-Ca temperature estimates are the Paradox formation in southeastern Utah, the Muddy Creek formation in southwestern Utah, the Arapien shale in central Utah, the Preuss formation in northeastern Utah, and Playa salts in much of western Utah. The Roosevelt KGRA is the most attractive target identified by Na-K-Ca geothermometry. Hydrothermal alteration, heavy metal distribution, and water chemistry provide additional characterization of the Roosevelt system. Chemistry of a cool water seep (25/sup 0/C) shows Na-K-Ca temperature of 241/sup 0/C and SiO/sub 2/ temperature of 125/sup 0/C. A Phillips well flowing from below 1500' (457m) shows Na-K-Ca temperature of 262/sup 0/C, SiO/sub 2/ temperature of 262/sup 0/C, and K of 1.5 times the surface spring value. The near …

Research and development of stabilized multifilamentary Nb/sub 3/Sn superconductors. Technical report, January 1, 1976--September 30, 1976

The basic objectives of this work included: making additional test samples of 1000 A (at 12 T) conductor, scaling up the production of 3500 A conductor to larger billets, and improving the performance of 1000 A size conductor by utilizing 13.5 wt% tin-bronze rather than 10% bronze. Additional samples of 1000 A conductor were made successfully from a 51 mm diameter third-stage billet.

A 187 mm diameter third-stage billet of 3500 A configuration, packed with hexes from two scaled-up 152 mm diameter second-stage billets, was unsuccessful. Longitudinal cracks appeared in some portions of the second-stage extrusions during drawing. Multiple breaks were found in each of the tantalum barriers after drawing the third-stage extrusion. It is not yet clear whether these problems are attributable to impurities, or unfavorable metallurgical conditions in the tantalum or the bronze, or to scaling up to …
