Combined Analytical/Numerical Approaches to Solving Fluid Flow Problems in the Unsaturated Zone at Yucca Mountain
Various analytical and numerical approaches are presented for the study of unsaturated flow processes in the vicinity of the Yucca Mountain, Nevada, the proposed site of an underground...
An Investigation of the Mechanical and Hydrologic Behavior of Tuff Fractures Under Saturated Conditions
The mechanical and hydrologic behavior of natural-fractures in a partially welded tuff rock were investigated. Tuff cores, each containing part of the same natural fracture oriented subparallel...
Diffusion Coefficients and Hydraulic Conductivity in Unsaturated Hanford Soils and Sediments
Two groundwater transport parameters of some Hanford formation materials, the hydraulic conductivity and the diffusion coefficient, were measured to aid in predicting contaminant migration....
Prototype Testing for the Yucca Mountain Project
The U.S. Department of Energy, through its Yucca Mountain Project Office (YMPO), has been conducting prototype activities in welded and non-welded tuff. These activities are in preparation...

The Nuclear Energy Agency of the Organization for Economic Cooperation and Development (OECD/NEA) sponsors the International Stripa Project. The Stripa Project is open to participation...
The Status of the Site Characterization and Validation Program in Phase III of the OECD/NEA Stripa Project
In 1980, the International Stripa Project was organized under the aegis of the OECD Nuclear Energy Agency for the purpose of conducting research, at the Stripa mine in Sweden, related...
Concepts in Prototype Testing for In Situ Geomechanical Investigations at Yucca Mountain
Geomechanical investigations comprise a significant portion of the site characterization program to be conducted at Yucca Mountain, the site of a proposed repository for nuclear waste....
Prototype Heater Test of the Environment Around a Simulated Waste Package
This paper presents selected results obtained during the 301 day duration of the Prototype Engineered Barrier System Field Test (PEBSFT) performed in G-Tunnel within the Nevada Test Site....
Tomographic Geophysics for Better Subsurface Geologic Information
Geologic skepticism among engineers owes much of its origin to common ambigueties in geologic interpretations and the innate artistic aspects of geology and its related diciplines. Geophysical...
Application of Geophysical Methods for Fracture Characterization
One of the most crucial needs in the design and implementation of an underground waste isolation facility is a reliable method for the detection and characterization of fractures in zones...
The Application of Vertical Seismic Profiling and Cross-Hole Tomographic Imaging for Fracture Characterization at Yucca Mountain
In order to obtain the necessary characterization for the storage of nuclear waste, much higher resolution of the features likely to affect the transport of radionuclides will be required...
Seismic Characterization of Fracture Properties
Laboratory measurements of the mechanical stiffness, hydraulic conductivity and seismic properties of three natural fractures were made as a function of applied normal stress. Seismic...
Modeling of Coupled Heat-Mass-Stress Effects in Geologic Media
To investigate the importance of coupled hydraulic-thermal-mechanical processes for the potential nuclear waste storage repository at the Yucca Mountain, a computer code is being developed....
Origin of Carbonate Deposits in the Vicinity of Yucca Mountain, Nevada: Preliminary Results of Strontium-Isotope Analyses
As part of the paleohydrology study of the Yucca Mountain Project, strontium-isotope analyses of carbonate deposits, ground water, and major rock reservoirs of strontium are in progress....
Uranium-Series Dating of Secondary Carbonates Near Yucca Mountain, Nevada: Applications to Tectonic, Paleoclimatic, and Paleohydrologic Problems
Near-surface accumulations of secondary carbonates are common in the soils and sediments of the Yucca Mountain area. These carbonates contain small amounts of uranium that allow dating...
Reconnaissance ? ??C and ??8O Data from Trench 14, Busted Butte, and Drill Hole G-4, Yucca Mountain, Nevada Test Site
Trench 14 was excavated to investigate the extent of Quaternary movement on the Bow Ridge fault, a north-south structure on the east side of Yucca Mountain. The trench exposes calcite...
Sellafield?From High Level Notoriety to Intermediate Acceptance
After a highly publicised accident at Sellafield, involving radioactive pollution, a period of continuous adverse media coverage eroded public confidence in the plant and its operators,...
Yucca Mountain Project Public Interactions
The U.S. Department of Energy (DOE) is committed to keeping the citizens of Nevada informed about activities that relate to the high-level nuclear waste repository program. This paper...
Dispute Resolution ? A New Approach for Public Acceptance of the High-Level Radioactive Waste Mamagement Regulatory System
