The PowerBarge
Following a brief description of the prefabricated floating PowerBarge concept, the range of application and expected cost and time savings is presented. Environmental benefits are described...
Interim Spent-Fuel Storage Options at Commercial Nuclear Power Plants
Although spent fuel can be stored safely in waterfilled pools at reactor sites, some utilities may not possess sufficient space for life-of-plant storage capability. In-pool storage capability...
Projections for Reduction in Lake Acidification From SO2 Emission Reductions
The Acid Deposition Assessment Model (ADAM) is used to assess the possible range of effects of a national acid rain emission reduction plan on lake chemistry and fish populations in the...
Reviewing the History and Activity of FERC
Since passage of the Federal Water Power Act in 1920 (Part I of the Federal Power Act, 16 U.S.C. 791a et seq.), Congress has required those seeking to construct, operate, or maintain hydroelectric...
Facing the 21st Century with an Aging Hydro System
The Tennesse Valley Authority (TVA) has implemented a comprehensive study of their hydroelectric plants in order to extend their service life for the next 50 years into the 21st century....
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...
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...
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...
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...
Mineralogic Alteration History and Paleohydrology at Yucca Mountain, Nevada
The importance of paleohydrology to the Yucca Mountain Site Characterization Project derives from the role water will play in radioactive-waste repository performance. Changes in hydrologic...
Lubrication Theory Analysis of the Permeability of Rough-Walled Fractures
Lubrication theory is used to study the permeability of rough-walled rock fractures. Two idealized models of a fracture, in which the roughness follows a sinusoidal or a sawtooth variation,...
Modelling of Hydro-Thermo-Mechanical Effects in a Fracture Intersecting a Nuclear Waste Deposition Hole
The groundwater flow in a vertical fracture intersecting a hypothetical nuclear waste deposition hole was examined. After excavation and emplacement of the nuclear waste canister, the...
Microwave Measurements of the Water Content of Bentonite
The theory of operation of microwave coaxial resonators is described. Sample preparation and the application of resonator techniques to the measurement of the permittivity (dielectric...
