Flow Visualization and Relative Permeability Measurements in Rough-Walled Fractures
Two-phase (gas-liquid) flow experiments were done in a natural rock fracture and transparent replicas of natural fractures. Liquid was injected at constant volume flow rate, and gas was...

Modeling Gravity-Driven Fingering in Rough-Walled Fractures Using Modified Percolation Theory
Pore scale invasion percolation theory is modified for imbibition of wetting fluids into fractures. The effects of gravity, local aperture field geometry, and local in-plane air/water...

Wetting Front Instability in an Initially Wet Unsaturated Fracture
Experimental results exploring gravity-driven wetting front instability in a pre-wetted, rough-walled analog fracture are presented. Initial conditions considered include a uniform moisture...

Experimental Studies to Calibrate Unsaturated Flow Models
Work is described that has been designed to serve as a laboratory calibration of numerical models for unsaturated flow studies. The experiment size is configured large enough that the...

Assessing Fault Rupture Hazard for the Proposed Repository at Yucca Mountain, Nevada: Demonstration of a Methodology Using Expert Judgments
As part of the Electric Power Research Institute's High Level Waste (EPRI HLW) performance assessment, we have developed and demonstrated a methodology to estimate the magnitude and likelihood...

HWVP Compliance with the Hanford Site Solid Waste Acceptance Criteria
This report describes the Hanford Waste Vitrification project (HWVP), which will be located at the Haford Site. The Hanford Site encompasses a 560-mi²...

Durability Testing of the High-Capacity GA-4/GA-9 Trailer
General Atomics (GA) is under contract to the US Department of Energy (DOE), Idaho Field Office, to develop two legal-weight truck from-reactor spent-fuel shipping casks with trailers....

Tolerance Requirements for Remote Handling at the Hanford Vitrification Project
A new and innovative approach to installation of the many remote nozzles and electrical connectors that must be installed to demanding tolerances has been developed by the architect/engineer...

Simulating the Behavior of Natural Geological Systems: Sources of Uncertainty and Bias
Post-closure performance assessments are used, in conjunction with controlled laboratory experiments and observations on natural systems, to generate confidence that a radioactive waste...

Yucca Mountain Site Characterization Project Exploratory Studies Facilities Construction Status
This paper discusses the progress to date on the construction planning and development of the Yucca Mountain Site Characterization Project (YMP) Exploratory Studies Facilities (ESF). The...

Stochastic Modelling of Groundwater Flow at the WIPP Site
A stochastic approach to modelling the groundwater flow in the vicinity of the WIPP site in New Mexico is described. A geostatistical model of the transmissivity of the Culebra dolomite...

Application of Indicator Geostatistics to the Gorleben Data Set
This paper describes a trial application of Indicator geostatistical methods to borehole data from the Gorleben site. Indicator variograms have been estimated from the site data and fitted...

Functional Analysis: The Path to Effective Training
The regulatory requirements under which the Yucca Mountain Site Characterization Project (YMP) operates mandate that worker proficiency be achieved and maintained. Individuals performing...

Project Control?The Next Generation
The Yucca Mountain Site Characterization Project (YMP) is the U.S. Department of Energy's (DOE) second largest Major System Acquisition Project. We have developed an integrated planning...

League of Women Voters Education Fund?Providing a Forum for Public Information and Participation
In March of 1992, the League of Women Voters Education Fund (LWVEF) signed a five-year cooperative agreement with the Department of Energy (DOE) to provide American citizens with information...

Resource Implications of Listing Columbia River Basin Salmon Stocks Under the Endangered Species Act
The Columbia River and Snake River dams and reservoirs provide substantial benefits in the Northwest through their operation for hydropower, flood control, irrigation, navigation, and...

Mount St. Helens Recovery Project
Work began immediately after the eruption of Mount St. Helens to restore Columbia River navigation, provide 100 year flood protection for the downstream communities located along the Cowlitz...

Basin Scale Management of Surface and Ground Water
An important element in the economic development of many regions of the Great Plains is the availability of reliable water supply. The primary supply has tended towards developing groundwater...

Fresno/Clovis Water Management Plan
The Fresno/Clovis Metropolitan Area (FCMA) in California has historically relied solely on untreated, undisinfected groundwater as a source of potable water to serve 500,000 people. Contamination...

Urban Water Planning?A Western Nevada Case Study
The result of the increased demands due to population growth in the Reno/Sparks urban area and new uses i.e., environmental and Pyramid Lake related, has created increased competition...
