The four connections for the control dewar and VLPC bayonet can platform are designed, using finite element analysis, to carry all dead weight and live loads. Based on the loads applied to the platform, two 1 inch thick plates and two 3/4 inch thick brackets made of ASTM A572-Grade 42 are required. The 1 inch thick plate requires a 3/8 inch thick intermediate steel material, between the 8-inch x 4-inch x 1/4-inch boom and the plate, for load reinforcement as well as weld area reinforcement. Both the plates and the brackets require 3/4 inch steel bolt connections.

A report emphasizing the necessity for continued Arctic Research as the area becomes increasingly important, both regionally and globally.

In the process of coal cleaning operations, a significant amount of coal is washed away as waste into the ponds. Clearly, such a large quantity of dumped coal fines has a detrimental effect on the environment. This investigation presents in innovative approach to recover and utilize waste coal fines from the preparation plant effluent streams and tailing ponds. Due to the large moisture content of the recovered coal fines, this study is focused on the utilization of coal fines in the coal-water slurry fuel (CWSF). The CWSF consists of 53.3% weight solids with a viscosity of less than 500 centipoise and 80-90% of solids passing 200 mesh. The 53.3% weight solids constitute a blend of 15% effluent recovered coal fines and 85% clean coal. It is the authors premise that a blend of plant coal and recovered waste coal fines can be used to produce a coal-water slurry fuel with the desired combustion characteristics required by the industry. In order to evaluate these characteristics the coal-water slurry fuel is fired in a test furnace at three firing rates (834,330 Btu/hr, 669,488 Btu/hr and 508,215 Btu/hr) with three different burner settings for each firing rate. Combustion tests were conducted to determine …

Coal cleaning is a technology that can solve a broad array of environmental problems associated with older, state-of-the-art, and future electric generating stations. Coal cleaning provides many environmental benefits. It reduces the concentration of inorganic minerals and elements found in association with coal, some of which are potentially toxic even though they are found in coal in only trace amounts. Currently, more sulfur and related S0{sub 2}, is removed by coal cleaning than by all post-combustion technologies combined. By increasing thermal efficiency and reducing parasitic power requirements, coal cleaning reduces all power plant emissions per unit of electricity produced, including S0{sub 2}, NO{sub x} C0{sub 2}, and hazardous air pollutant precursors (HAPs). While coal cleaning is a mature technology, in the past coal cleaning has only been used for the comparatively simple purposes of removing ash-forming and sulfur-bearing minerals. The application of this technology to H APs control will require a more sophisticated approach, based on a fundamental understanding of the mechanisms of trace element removal. The trace elements named as HAPs in the 1990 Amendments to the Clean Air Act can occur in coal in numerous forms. For example, antimony is believed to be present in pyrite, accessory sulfides …

The mathematical models and numerical methods employed by the FEHM application, a finite-element heat- and mass-transfer computer code that can simulate nonisothermal multiphase multi-component flow in porous media, are described. The use of this code is applicable to natural-state studies of geothermal systems and groundwater flow. A primary use of the FEHM application will be to assist in the understanding of flow fields and mass transport in the saturated and unsaturated zones below the proposed Yucca Mountain nuclear waste repository in Nevada. The component models of FEHM are discussed. The first major component, Flow- and Energy-Transport Equations, deals with heat conduction; heat and mass transfer with pressure- and temperature-dependent properties, relative permeabilities and capillary pressures; isothermal air-water transport; and heat and mass transfer with noncondensible gas. The second component, Dual-Porosity and Double-Porosity/Double-Permeability Formulation, is designed for problems dominated by fracture flow. Another component, The Solute-Transport Models, includes both a reactive-transport model that simulates transport of multiple solutes with chemical reaction and a particle-tracking model. Finally, the component, Constitutive Relationships, deals with pressure- and temperature-dependent fluid/air/gas properties, relative permeabilities and capillary pressures, stress dependencies, and reactive and sorbing solutes. Each of these components is discussed in detail, including purpose, assumptions and …

This project reactivates ARCO�s idle Pru Fee property in the Midway-Sunset field, California and conducts a continuous steamflood enhanced oil recovery demonstration aided by an integration of modern reservoir characterization and simulation methods. Cyclic steaming was used to reestablish baseline production within the reservoir characterization phase of the project. During the demonstration phase begun in January 1997, a continuous steamflood enhanced oil recovery was initiated to test the incremental value of this method as an alternative to cyclic steaming. Other economically marginal Class III reservoirs having similar producibility problems will benefit from insight gained in this project. The objectives of the project are: (1) to return the shut-in portion of the reservoir to optimal commercial production; (2) to accurately describe the reservoir and the recovery process; and (3) to convey the details of this activity to the domestic petroleum industry, especially to other producers in California, through an aggressive technology transfer program.

Ash behavior in power systems can have a significant impact on the design and performance of advanced power systems. The Energy & Environmental Research Center (EERC) has focused significant effort on ash behavior in conventional power systems that can be applied to advanced power systems. This initiative focuses on filling gaps in the understanding of fundamental mechanisms of ash behavior that has relevance to commercial application and marketable products. This program develops methods and means to better understand and mitigate adverse coal ash behavior in power systems and can act to relieve the U.S. reliance on diminishing recoverable oil resources, especially those resources that are not domestically available and are fairly uncertain.

This document presents a compilation of chemical and isotopic data for groundwater samples analyzed by Lawrence Livermore National Laboratory (LLNL) in support of the Hydrology and Radionuclide Migration Program (HRMP) and the Underground Test Area Program (UGTA) for the U.S. Department of Energy, Nevada Operations Office. Included are data for 107 samples collected from wells and springs located on and around the Nevada Test Site (NTS), within an area approximately bounded by latitudes 36{sup o} to 38{sup o}15'N and longitudes 115{sup o} to 117{sup o}15'W. The samples were collected during the time period 1992 to early 1997. The data represents one of the largest internally consistent geochemical data sets to be gathered for groundwater in southern Nevada. This database is available in electronic or hardcopy formats to interested parties upon request. In addition to the LLNL data we have included a table of selected isotopic data summarized from a larger database compiled by GeoTrans, Inc. (1994). This data is included for comparative purposes as a means of placing the LLNL data in the context of other data for the same geographic region.

Researchers at the Idaho National Engineering and Environmental Laboratory tested the performance of electric motors and actuator gearboxes typical of the equipment installed on motor-operated valves used in nuclear power plants. Using a test stand that simulates valve closure loads against flow and pressure, the authors tested five electric motors (four ac and one dc) and three gearboxes at conditions a motor might experience in a power plant, including such off-normal conditions as operation at high temperature and reduced voltage. They also monitored the efficiency of the actuator gearbox. All five motors operated at or above their rated starting torque during tests at normal voltages and temperatures. For all five motors, actual torque losses due to voltage degradation were greater than the losses calculated by methods typically used for predicting motor torque at degraded voltage conditions. For the dc motor the actual torque losses due to elevated operating temperatures were greater than the losses calculated by the typical predictive method. The actual efficiencies of the actuator gearboxes were generally lower than the running efficiencies published by the manufacturer and were generally nearer the published pull-out efficiencies. Operation of the gearbox at elevated temperature did not affect the operating efficiency.

Experiments were established at Tully, New York, by the State University of New York College of Environmental Science and Forestry, in cooperation with the University of Toronto and the Ontario Ministry of Natural Resources, to assess the potential of willows for wood biomass production. Specific objectives included determining the effects of clone type, fertilization, spacing, cutting cycle, and irrigation on biomass production. Production was high, with willow clone SV1 yielding nearly 32 oven dry tons per acre (odt ac{sup -1}) with three-year harvest cycle, irrigation, and fertilization. Clone type, fertilization, spacing, cutting cycle, and irrigation all significantly affected biomass production. Willow clone-site trials planted at Massena, and Tully, NY in 1993 grew well during 1994 and 1995, but some clones in the Massena trial were severely damaged by deer browse. Several new cooperators joined the project, broadening the funding base, and enabling establishment of additional willow plantings. Willow clone-site trials were planted at Himrod, King Ferry, Somerset, and Tully, NY, during 1995. A willow cutting orchard was planted during 1995 at the NYS Department of Environmental Conservation Saratoga Tree Nursery in Saratoga, NY. Plans are to begin site preparation for a 100+ acre willow bioenergy demonstration farm in central New …
