Choosing and implementing a computer system for plant lubrication: Nine steps to success (open access)

Choosing and implementing a computer system for plant lubrication: Nine steps to success

Rapid advances in computer software offer may opportunities for increasing efficiency and productivity; however, choosing the right software package and achieving its full potential can be a challenging task. Lubrication engineers faced with the selection and implementation of a computer system will find that they can increase their chance of success when they follow the nine steps outlined in this paper. These steps provide a solid framework for managing the project through its full life-cycle from initial conception until final retirement of the system. Lubrication Departments that already have computer systems in place can also benefit from these steps by picking up at the corresponding point in the system's life and following the remaining steps.

Estimate of earth media shear strength at the Nevada Test Site (open access)

Estimate of earth media shear strength at the Nevada Test Site

A method is presented of estimating the effective shear strength of the fractured rock that surrounds a nuclear detonation. To do this, we measure the cavity radii from previous detonations. We also use numerical computer codes to model the explosion phenomenology and develop the functional relationship between the normalized cavity displacement and the normalized shear strength of the rock. In this sense, the computer codes serve as replica models that are dimensionally analyzed to interpret the field experience. We separate the effects of gravity and overburden pressure from the effects of the material properties and give scaling laws for each. We have analyzed approximately 300 nuclear detonations at the Nevada Test Site (NTS) and have found that the most frequent shear strengths are between 0.020 and 0.060 kbars. They are also essentially independent of the depth-of-burial ranges considered. We obtained good agreement between predicted shear strengths and those measured from core samples for different areas at the Nevada Test Site.

Characterization of major waste data sources (open access)

Characterization of major waste data sources

The US Department of Energy (DOE) recently initiated the Industrial Waste Reduction Program, which seeks to develop and commercialize waste reduction technologies and practices that will reduce industrial energy use. The Industrial Waste Reduction Program, like the other programs under DOE's Office of Industrial Technologies (OIT), works with industry to focus research and development resources according to industry needs and market opportunities. The Program consists of five fundamental elements: industrial waste characterization, opportunity assessments, technology research and development, technology and information transfer, and, institutional analysis. This report is a product of efforts initiated under the first of these program elements, Industrial Waste Characterization. Its purpose is to increase understanding of the types and magnitudes of industrial waste streams. In particular, this report presents the key characteristics of selected waste, energy, and economic data sources in an effort to clarify the scope, consistency, and limitations of the data. It is expected that this information will be used in another element of the program, Opportunity Assessments. That effort will identify priority technology needs by evaluating the available data; expert advice from industry, government, and academia; and independent analyses. 33 refs.

Uranium miner lung cancer study. Progress report, July 1, 1976--July 1, 1977 (open access)

Uranium miner lung cancer study. Progress report, July 1, 1976--July 1, 1977

This study was initiated in 1957 by the U.S. Public Health and many facets of this project are reaching final objectives. Many new studies have developed in the course of this study and will continue. The projects supported by the Energy Research and Development Administration are of utmost importance and consist of: collection of material from uranium miners known to have cancer of the lung into a tumor registry; manual on pulmonary cytology; regression study of sputum cytological findings in uranium miners who showed marked atypical squamous cell metaplasia and have quit smoking cigarettes, mining, or both; continuation of sputum collection and collection of lungs from deceased miners; sensory development for localization of carcinoma in situ of the lung; and lung histology program. Since we have examined approximately 77,000 sputum samples over the last 20 years in cases that showed normal cytology at the inception of the study and some subsequently developed carcinoma of the lung, we have an accumulation of material that is worthy of study and presentation.

Aquifer tests near the Idaho Falls Foothills, Idaho (open access)

Aquifer tests near the Idaho Falls Foothills, Idaho

Ground water pumping tests were performed in two wells located in the foothills east of Idaho Falls to determine the aquifer characteristics at these locations. These data were used to differentiate this aquifer from the Snake River Plain aquifer. The wells were pumped at rates of 11 and 14 gallons per minute with 0.03 and 0.04 ft of drawdown measured in the pumping wells. The transmissivity is estimated to be 525,000 gpd/ft and 450,000 gpd/ft, respectively. The hydraulic conductivity is 925 ft/day and 1,070 ft/day, respectively. These hydraulic conductivities are similar to those measured in the Snake River Plain aquifer. Water level data in these wells are consistent with the water table in the Snake River Plain aquifer and indicates ground water movement from the foothills toward the Plain. The high transmissivity suggests water may move rapidly from the foothills area to mix with water in the Snake River Plain aquifer. Elevated water temperatures (76 and 70{degrees}F) and high specific conductivities in these wells indicate the presence of a foothills aquifer with characteristics that can be used to separate the two aquifer systems.

Low-Cost Solar Array Project. Task I. Silicon material: investigation of the hydrogenation of SiCl/sub 4/. Fifth quarterly report

Reaction kinetic measurements on the hydrochlorination of SiCl/sub 4/ and mg silicon metal in the presence of a copper catalyst were last reported as a function of reaction temperature, reactor pressure and H/sub 2//SiCl/sub 4/ ratio, 3 SiCl/sub 4/ + 2 H/sub 2/ + Si ..-->.. 4 SiHCl/sub 3/. The same reaction was repeated at a lower catalyst loading of 2 wt%. In the presence of 2 wt% cuprous chloride (based on silicon metal), the hydrochlorination reaction rate is doubled to give about the same performance as those obtained at a higher copper catalyst loading. The effect of particle size distribution of the mg silicon metal on the hydrochlorination reaction rate was studied. Reaction kinetic measurements were made on 150 x 400 mesh Si and on 32 x 65 mesh Si in addition to the standard 65 x 150 mesh Si used in previous studies. Results of these experiments show that the reaction rate is essentially independent of the silicon metal particle size. Thus, the reaction occuring on the Si metal surface is the rate-determining step. Mass transfer via diffusion of reactants and product is not rate-limiting. A plausible mechanism of the hydrochlorination reaction is discussed.

LOFT emergency core coolant thermal analysis Class I review (open access)

LOFT emergency core coolant thermal analysis Class I review

The LOFT Emergency Core Coolant Piping Thermal Analysis was checked to insure that the calculations made would conservatively satisfy the requirements in the LOFT technical specifications. Some of the boundary conditions used have not been shown to be conservative and require review and possible re-analysis. One of the thermal models used could not be clearly related to a specific part of the piping geometry and requires further explanation. The remainder of the models, the use of the SIMIR code and the other boundary conditions appear conservative and reflect normal thermal analysis methodology and practice. However, the use of constant, rather than temperature varying, thermal properties for some materials may introduce a slight error in these analyses.

Comparison between calculation and measurement of energy deposited by 800 MeV protons (open access)

Comparison between calculation and measurement of energy deposited by 800 MeV protons

The High Energy Transport Code, HETC, was obtained from the Radiation Shielding Information Center (RSIC) at Oak Ridge National Laboratory and altered as necessary to run on a CDC 7600 using the LTSS software in use at LLNL. HETC was then used to obtain calculated estimates of energy deposited, for comparison with a series of benchmark experiments done by LLNL. These experiments used proton beams of various energies incident on well-defined composite targets in good geometry. In this report, two aspects of the comparison between calculated and experimental energy depositions from an 800 MeV proton beam are discussed. Both aspects involve the fact that workers at SAI had previously used their version of HETC to calculate this experiment and reported their comparison with the measured data. The first aspect addressed is that their calculated data and LLNL calculations do not agree, suggesting an error in the conversion process from the RSIC code. The second aspect is not independent of the first, but is of sufficient importance to merit separate emphasis. It is that the SAI calculations agree well with experiments at the detector plate located some distance from the shower plate, whereas the LLNL calculations show a clearcut discrepancy there …

Defluoridation study for Boise geothermal water (open access)

Defluoridation study for Boise geothermal water

Methods of removing fluorides from water are reviewed and recommendations are made for treating geothermal water used by the Boise Geothermal Project, Boise, Idaho. The Boise geothermal water except for its high fluoride content would be high quality, suitable for primary drinking water. Fluoride ranges from about 15 to 25 mg/l in water from various wells in the Boise region where the Project plans to obtain hot water. Four techniques for removing fluorides from water have been studied extensively during the past 15 years or so. Electrodialysis and reverse osmosis are useful in reducing total dissolved solids from brackish water, but are nonspecific and are too expensive for treatment of the Boise geothermal water. Selective precipitation is a widely used technique for treating water, but would also prove expensive for the Boise geothermal water because of the relatively high solubility of fluoride salts and consequently high concentration (and cost) of precipitants required to reduce the fluorides to an acceptable level. Ion-exchange separation using activated alumina as the exchange medium appears to be the most promising technique and we recommend that some laboratory and pilot studies be conducted to establish suitability and operating boundaries.

New Mexico's energy resources '81. Annual report of Bureau of Geology in the Mining and Minerals Division of New Mexico Energy and Minerals Department

Although production of U/sub 3/O/sub 8/ declined only slightly in 1980, New Mexico's share of domestic production has declined from 48% in 1976 to 35% in 1980. Production projections indicate a continued decline in 1981 and lower production until at least 1984. New Mexico has 41% of total domestic reserves producible in the $50-per-lb cost category. In keeping with the anticipated steady depletion of reserves, production of crude oil in New Mexico was 69.9 million bls, a 6.3% decline in production from 1979. Condensate production of 5.4 million bbls in 1980, however, represented an increase of 7% from 1979 production. Although natural gas production was the lowest since 1970 and declined by 2.6% from 1979 production, 1980 was the 15th year that production exceeded 1 trillion cu ft. Despite declines in production, the valuation of oil and gas production has increased significantly with oil sales doubling from the previous year and gas sales increasing by $409 million because of higher prices. Reserves have been estimated to be 959 million bbls of crude oil and 17.667 trillion cu ft of natural gas. Production of 19.5 million short tons of coal in 1980 represented a 33% increase over 1979 production and an …
