Automation of Union Electric's Hydro-Power Plants
Union Electric Company is spending twelve million dollars on Electronic Control and Monitoring equipment at two of their hydro-electric plants (a total of twenty-seven generating units)...
Acid Mine Drainage: An Overview
In the United States, acid mine water adversely affects over 6,500 km (4,000 miles) of rivers and streams. This is, however, a significant improvement over the situation two decades ago....
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...
Overview of Acid Mine Drainage Control Strategies
Since 1970, regulations requiring proper overburden sampling techniques to obtain representative geologic profiles and outline specific overburden analysis to determine acid-producing,...
The Pittsburgh MAGLEV Project
A passenger transportation crisis exists in the United States which experts predict will only worsen, wasting billions of U.S. dollars. Magnetic Levitation (MAGLEV) is a promising new...
The Growing Meet Market
The Delaware cities of Dover and Wilmington are only 5 mi apart. Their combined populations barely exceed 100,000. Yet each city is planning to build a new convention center to corner...
The Boundary Element Method in Engineering Practice
The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation,...
Development of the GA-4 and GA-9 Legal Weight Truck Spent Fuel Shipping Casks
General Atomics (GA) is developing two legal-weight-truck spent-fuel shipping casks for transporting commercial reactor spent fuel. The GA-4 pressurized-water-reactor (PWR) and the GA-9...
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...
Multiple Event Considerations for Postclosure Seismic Hazard Evaluations at Yucca Mountain, Nevada
Postclosure waste canister design requirements suggest the values used for seismic design have less than a 10% chance of being exceeded in a 1,000 year postclosure period. Considerably...
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...
Major and Trace Elements Regulation in Natural Granitic Waters. Application to Deep Radioactive Waste Disposals
In order to forecast the evolution of deep groundwaters in the environment of a radioactive waste disposal, one must be able to understand the behaviour of major and trace elements in...
Radiocolloid Transport in Saturated and Unsaturated Fractures
Studies have shown that radionuclides and toxic materials can attach to colloidal particles in groundwater or are themselves colloids. Since these contaminated particles can migrate several...
Design Reviews From a Regulatory Perspective
This paper presents views on the role of the licensing engineer in the design process with specific emphasis on design reviews and the automated information management tools that support...
Controlling the Description of a High-Level Radioactive Waste Isolation System
Control of large, complex, regulation-driven programs using traditional management methods has not been wholly effective. What is needed is a rigorous yet flexible method that is amenable...
Fractal Characteristics of Fracture Roughness and Aperture Data
In this study mathematical expressions are developed for the characteristics of apertures between rough surfaces. It shown that the correlation between the opposite surfaces influences...
Conceptual Design Study of Geological Disposal System of High-Level Waste
Conceptual design study of geological disposal system for HLW was carried out taking into account geological environment in Japan, in order to provide disposal concepts for integrated...
