Coal Ash and Dredged Material in Reef Construction
Cleanup of a Coal Tar Deposit Using a Vacuum Clam
Behavior of Foundations Subjected to Large Ground Movements
The behavior of twelve linear test foundations above an advancing longwall coal mine panel was observed. Three phases of deformation were observed in the centerline foundations: tension,...
Geophysical Methods for Fracture Characterization in and Around Potential Sites for Nuclear Waste Disposal
Historically, geophysical methods have been used extensively to successfully explore the subsurface for petroleum, gas, mineral, and geothermal resources. Their application, however, for...
Seismic Stabilization of St. Joe State Park Tailings Dams
Tailings dams constructed by the `upstream' method are known to be seismically vulnerable, but field experience indicates that their seismic stability usually improves following termination...
Sedimentation Pond Removal in Eastern Ohio Coal Mining
Due to the large number of sedimentation ponds used in surface coal mining, efficient, economical, and environmentally acceptable methods for sedimentation pond removal and reclamation...
The Annotated Outline Process for a Mined Geologic Disposal System License Application
The U.S. Department of Energy (DOE) is studying Yucca Mountain, Nevada, as a potential site for a mined geologic repository for high-level nuclear waste. DOE has the responsibility to...
Research at Howard University on Retardation of Radionuclides by Sorption Processes During Host Rock—Ground Water Interactions
Extensive sorption measurements were made over a period of several years, of major radionuclides in J-13 Well water with Yucca Mountain tuff samples. Most of these measurements were single...
Use of Coupled Geochemical and Transport Calculations for Nuclear Waste Problems
The dissolution and migration of radionuclides from a final repository for radioactive waste is complex chemically. The dissolution and release rates depend on the chemistry and on advective...
Yucca Mountain Site Characterization Project Performance Based Q List
In mid-1992, the Yucca Mountain Site Characterization Project (YMP) initiated a performance based 'Q' List development effort. This effort is intended to evolve a 'Q' List based upon the...
Borehole Security on the Yucca Mountain Project
A borehole security plan was developed and is being implemented to address safety, environmental protection and restoration, waste isolation, and security concerns related to boreholes...
Calcite Deposits in Fractures at Yucca Mountain, Nevada
Calcite is one of the latest-formed minerals within fractures at Yucca Mountain. Petrographic and chemical studies of these calcites have the potential, in conjunction with fluid-inclusion...
Fly Ash for use in the Stabilization of Industrials Wastes
Fly ash and other coal combustion by-products are used in the stabilization of industrial wastes. This paper describes the various types of fly ashes, the mechanisms of strength development,...
Utilization of Industrial By-Products for Construction Materials
The United States is a major producer of agricultural, industrial, mining, and municipal waste materials in the world. Traditional methods of waste disposal most often have resorted to...
An Integrated Approach Toward Characterization of Radionuclide Transport at Yucca Mountain, Nevada
A major effort of site characterization activities at Yucca Mountain, Nevada, a site being studied by the U.S. Department of Energy (DOE) as a potential repository of high-level radioactive...
Present and Future Use of Coal Ash in Construction and Related Applications
The American Coal Ash Association, Inc. (ACAA) is an organization of producers and marketers of coal combustion by-products. An annual survey of coal-burning electric utilities is conducted...
