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

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

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

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)

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 …

Assessment of radiological impact of the inactive uranium-mill tailings pile at Salt Lake City, Utah (open access)

Assessment of radiological impact of the inactive uranium-mill tailings pile at Salt Lake City, Utah

One of the largest inactive uranium mill tailings piles in the United States is located within metropolitan Salt Lake City, Utah. A radiological survey was performed at this site during the fall of 1975. A series of field and laboratory analyses were performed to characterize the spread of contamination from the tailings pile to surrounding areas. These analyses provided a basis for discussion of the important pathways for transport of radioactivity to man. Measurements of radionuclide concentrations in soil indicated that radium had migrated up to one meter into soil beneath the tailings. Tailings material was found out to distances of several hundred meters, mostly in the prevailing wind directions. Elevated levels of /sup 226/Ra, /sup 238/U, /sup 230/Th, and /sup 210/Pb were found in sediments of streams running through the mill site; but in Jordan River samples, radionuclide concentrations were of the same magnitude as background samples collected in other parts of the Salt Lake Valley. Atmospheric dispersion of radon gas, which emanates from the pile continuously, was calculated. Potential health effects for continuous exposure to radon progeny and external gamma radiation from the pile in its current state were estimated using risk estimators presented in the BEIR report. …

Considerations of the social impact of fusion power (open access)

Considerations of the social impact of fusion power

It is concluded that the direct effects of an ideal form of fusion technologies would be socially more desirable than those of the alternatives. This is particularly true of the second generation fusion power plant. However, given our technological inputs, this was a trivial result. Less trivial was consideration of the negative effects that might accrue through the availability of potentially unlimited supplies of low cost energy. It is concluded that while there may be reasonable humanist argument both for and against such abundance, in a democratic society control of energy development for its own sake is likely to be unacceptable. However, if the indirect effects of pollution, despoilment, and resource depletion through ever expanding energy use become sufficiently disturbing to the well-being of the majority, unlimited energy may come to be seen as undesirable by the society. To this extent successful research and development for unlimited sources such as the fusion or mixed solar alternatives might be judged from some point far in the future to have been a mistake. This could occur even though advances in the technology of pollution control and resource use greatly reduce the pollution and hazard accompanying a much higher rate of energy utilization.

Thermal depletion of a geothermal reservoir with both fracture and pore permeability (open access)

Thermal depletion of a geothermal reservoir with both fracture and pore permeability

A method for estimating the useful lifetime of a reservoir in porous rock where the injection and production wells intersect a fracture system is presented. Equations were derived for the pore-fluid and fracture-fluid temperatures averaged over large regions of the geothermal field. Problems such as incomplete areal sweep and interfingering of cool and hot fluids are ignored. Approximate equations relating average temperatures to the heat flowing from rock to fluid were developed, and their use is justified by comparing the results with solutions of the exact equations. The equations for the temperature decline can be solved quickly. In the model, fractures are characterized by three parameters: aperture w, permeability k/sub fr/, and spacings between fractures D. For certain values of these parameters, cool reinjected fluid in fractures may reach the production wells long before all the warm pore fluid has been tapped, shortening the useful lifetime of the field. The traditional (and important) problems of reservoir engineering, flow rate determination, drawdown, sweep patterns, etc. were ignored. Thus the results are most useful in providing a correction factor which can be applied to lifetime estimates obtained from a detailed simulation of a field assuming porous rock. That correction factor is plotted …

Engineering aspects of geothermal development in the Imperial Valley

In order to provide background for introduction of a Geothermal Element into the General Plan of the County of Imperial, California, studies were conducted on resource evaluation, engineering development, environmental impact, economics, regulation, and so forth. This document is a collection of reviews of engineering matters pertinent to the County's plan. Briefly, the contents include discussions of drilling practice, costs, and land requirements. Brief notes on reinjection and on fluid transmission follow. The section on power plants attempts to give scaling relationships for land area, costs, and performance, according to size and reservoir temperature. The problem of cooling power plants is important, particularly in an arid agricultural area. Cooling requirements, water availability, and water suitability are discussed in turn. The question of the interactions of the hydrologic cycle, withdrawals for cooling, and the Salton Sea is covered in a separate EQL document. Finally, there are sections devoted to nonelectrical uses for the geothermal resources, including production of fresh water and chemicals. The direct uses for geothermal heat are not included.
