Mercury Porosimetry Studies on a Natural Fracture
Mercury porosimetry techniques were used to study the effects of stress on the capillary pressure characteristics of a single natural fracture. In addition, permeability measurements were...
Small-Scale Behavior of Single Gravity-Driven Fingers in an Initially Dry Fracture
Experiments investigating the behavior of individual, gravity-driven fingers in an initially dry, rough-walled analog fracture are presented. Fingers were initiated from constant flow...
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...
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...
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...
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...
An Isolated Wetland Used for Stormwater Treatment
A marsh used for stormwater management showed gradually increasing levels of pH, dissolved oxygen and conductivity in the flow path. The system was especially effective in removing suspended...
Water Quality Impacts from Development of Port Ludlow, Washington
Port Ludlow Bay is a tidal estuary located adjacent to Admiralty Inlet in Puget Sound, Washington. A planned development has been under construction along the bay since 1976. A 0.64 mgd...
Water Quality Model of the Chicago Waterway
In 1992, the Metropolitan Water Reclamation District of Greater Chicago (the District) developed a QUAL2E water quality model of the Chicago waterway and Upper Illinois waterway. The model...
GIS Reconstruction of Exposure to Water Supply Contaminants
Groundwater pollution resulting from improper waste handling practices in the aerospace industry contaminated the water supply in Tucson, Arizona. State and federal health officials concluded...
Seasonal Water Quality Management Given Sparse Data
An approach for designing robust seasonal water quality management programs for river basins with sparse or short flow records is presented. This approach uses Markov chain modelling and...
A Planning Strategy for Safe Drinking Water Act Compliance
This paper presents a simple planning strategy for drinking water utilities that will allow them to move ahead with system upgrades and specific regulatory compliance programs even though...
Groundwater Contaminant Transport at a Hazardous Waste Disposal Site, Pullman, Washington
Groundwater contamination at a hazardous waste site near Pullman, Washington is simulated by a numerical model. The aquifer at the site is classified as an unconfined valley aquifer. Solute...
Investigation and Rehabilitation of the Moses Lake Larson Wellfield
In 1988, low levels of trichloroethylene (TCE) were detected in several of the Larson wells operated by the City of Moses Lake. The wells are up to 800 feet deep and are completed in fractured...
