A Model to Predict the Production Rate of AMD
Results generated from a model to deterministically calculate the production rate of acid mine drainage compared to those generated by an empirical model are nearly identical. The model...

Wetlands for Acid Mine Drainage Treatment
Wetlands are being constructed on mined lands to treat acid mine drainage. Most of these wetlands remove a substantial amount of iron and sulfate from the water, but manganese removal...

Acid Mine Drainage Control Utilizing Fly Ash
Acid mine drainage is a serious environmental problem confronting the Appalachian region. Fly ash, the air particulate residual from the combustion of coal, is also an environmental concern...

Ash Disposal at Coal Creek Station
This paper outlines the effort of two utilities to minimize the impact of an 1100 megawatt lignite fired plant's waste stream on the environment. Current regulations, poor...

Building Beneath Boston
Up/down construction is a method in which a project's substructure and superstructure are simultaneously built. The substructure's wall, column and foundation...

The Human Factor in Failures
Human shortcomings cause three-quarters of project failures. A study of 500 case histories led to this assumption. One such failure at the Walter Bouldin dam in Alabama, is described in...

Making the New Look Old
Between March 1990 and January 1991, Annapolis buried overhead utilities and reconstructed the roadway around the historic State House, built in 1769. The paving stones, colonial-appearing...

Jailhouse Design
According to statistics from national corrections groups, the inmate population in the U.S. has reached 1 million and could double by 1995. With the constant need for more beds, engineers...

Regulatory Issues Impacting the U.S. High-Level Radioactive Waste Management Program
This paper addresses current key regulatory issues impacting the U.S. high-level radioactive waste management program. The following issues pertain to the licensing of a geologic repository:...

Safety Assessment of Radioactive Waste Disposal: A Priority Area for International Co-operation Within the OECD Nuclear Energy Agency
The OECD/NEA programme in the radioactive waste management area gives a high priority to long-term safety aspects of radioactive waste disposal practices. Overall aims of this part of...

OCRWM Transportation Technical Activities for 1998
The Office of Civilian Radioactive Waste Management is preparing for the transport of spend fuel by 1998 from commercial reactors to a monitored retrievable storage facility. The preparations...

Volcanic Episodes Near Yucca Mountain As Determined by Paleomagnetic Studies at Lathrop Wells, Crater Flat, and Sleeping Butte, Nevada
It has been suggested that mafic volcanism in the vicinity of Yucca Mountain, Nev., is both recent (20 ka) and a product of complex 'polycyclic' eruptions. This...

40Ar/?9Ar Laser Fusion and K-Ar Ages From Lathrop Wells, Nevada, and Cima, California: The Age of the Latest Volcanic Activity in the Yucca Mountain Area
K-Ar and 40Ar/39Ar ages from the Lathrop Wells volcanic center, Nevada, and from the Cima volcanic field,...

Tools for LWR Spent Fuel Characterization: Assembly Classes and Fuel Designs
Tools for the classification of fuel assembly types have been developed during the development of the Characteristics Data Base. The assembly class scheme is based upon the design of the...

Dissolution of Spent Fuel Under the Conditions of Wet Storage and Disposal
The release of cobalt and cesium from PWR spent fuel rods with three types of artificial defects made on their clads in demineralized water and also the dissolution of uranium from unirradiated...

Differentiating Between Education and Indoctrination
