Diffusion of Carbon Dioxide Through Layers of the Unsaturated Zone at Yucca Mountain
The estimation of diffusive transport of gases through tuffs is important in order to asses the Yucca Mountain as an environmentally safe and acceptable repository for spent fuel and high-level...

Organic Carbon Input in Shallow Groundwater at ?SP?, Southeastern Sweden
The variation in carbon and oxygen isotopes in calcite fissure fillings and dissolved carbonate from shallow groundwaters has been examined at Aspo, southeastern Sweden. The shallow water...

Radionuclide Solubility and Speciation Studies for the Yucca Mountain Site Characterization Project
Yucca Mountain, Nevada, U.S.A., is being investigated for its suitability as a potential site for a geologic nuclear waste repository. As part of the site characterization studies, actinide...

Late Quaternary History and Uranium Isotopic Compositions of Ground Water Discharge Deposits, Crater Flat, Nevada
Three carbonate-rich spring deposits are present near the southern end of Crater Flat, NV, approximately 18 km southwest of the potential high-level waste repository at Yucca Mountain....

Corrosion Life-Time Assessment of Carbon Steel and Stainless Alloys for Geological Disposal Facility
The disposal facility for radioactive wastes, requires long-term integrity. Metal is considering to use as the engineered barrier which constructs the outer walls in such a facility, in...

Lead Isotopic Composition of Paleozoic and Late Proterozoic Marine Carbonate Rocks in the Vicinity of Yucca Mountain, Nevada
Paleozoic and Late Proterozoic marine carbonate rocks (limestones, dolomites, and their metamorphic equivalents) cropping out in the vicinity of Yucca Mountain contain lead with an isotopic...

Using Wood as Structural Material: Some Environmental Considerations
Against a background of growing public awareness of the potential dangers of global warming resulting from increasing concentrations of carbon dioxide in the atmosphere it is suggested...

Effect of Active Control on Closely Spaced Natural Frequencies
Current problems in structural control involve structures with closely spaced natural frequencies (M.J. Balas, 1983). The purpose of this paper is to show how control affects a structure...

Full Scale Application of Active Bracing Systems
A full scale active bracing system has been installed in a structure in Tokyo, Japan. The practical problems associated with the implementation of this system, and the corresponding solutions...

Recent Findings in Active Structural Control
Over the past decade, tremendous advancements have been made in the development of structural control paradigms and in the necessary supporting technologies. The fundamental paradigm that...

Flexural and Shear Studies of Carbon Fiber Reinforced Beams
This paper presents the results of laboratory test on beams reinforced with three dimensional continuous carbon fiber grid. The grid is prefabricated by three-dimensional weaving and epoxy...

Intersection Air Quality Analysis
Methods of carbon monoxide concentration estimation at or near intersections have recently undergone scrutiny with resulting debate on the proper and accurate ways to make these estimates...

Modeling Guideline for Air Quality Analysis of Intersections
Model evaluations have been performed testing eight different models for the ability to estimate carbon monoxide near intersections. These evaluation results along with the need for updated...

Effect of Active Control to Structural Reliability
Most available results in the study of structural reliability deal with idealized mathematical representation of structures. With model supported diagnosis of the structural condition...

Determining Causes for Taste and Odor in Bandar Abbas's Drinking Water
In the south of Iran on the shore of Persian Gulf, Bandar Abbas has a population of over 450,000. The means annual rainfall of Bandar Abbas is less than 205 millimeters of precipitation...

Keys to Better Meetings
Few management or professional activities chew up as much time as meetings. There are, however, two keys to better meetings that are often overlooked. They help tap the collective wisdom...

Preliminary National Evaluations of CO2 Emission Controls
Under the aegis of the International Energy Agency, several countries have begun making comparable studies of the cost-effectiveness of various measures to reduce emissions of carbon dioxide...

Exploring CO₂ Emissions Reduction Strategies
Concern for potential climate change resulting from the greenhouse effect may be the biggest factor in energy planning in the 1990s. A 20% reduction in CO₂,...

Electric Utility Planning for Greenhouse Concerns
International concerns for the potential of significant climate change resulting from the greenhouse phenomenon have focused increasing attention on the emissions of carbon dioxide and...

Potential ?⁴CO₂ Releases from Spent Fuel Containers at Yucca Mountain
