Field Investigation of Mining-Induced Seismicity on Local Geohydrology
Hydraulic response of the rock mass due to earthquakes is one of the concerns in the assessment of the long-term performance of a repository. Studies performed by other researchers indicated...

Influence of Deterministic Geologic Trends on Spatial Variability of Hydrologic Properties in Volcanic Tuff
Hydrologic properties have been measured on outcrop samples taken from a detailed, two-dimensional grid covering a 1.4 km outcrop exposure of the 10-m thick nonwelded-to-welded, shardy...

Development of 3-D Lithostratigraphic and Confidence Models at Yucca Mountain, Nevada
Computerized three-dimensional geologic models of potential high-level nuclear waste repositories such as Yucca Moutain, Nevada, are important for visualizing the complex interplay of...

Estimation of Water-Filled and Air-Filled Porosity in the Unsaturated Zone, Yucca Mountain, Nevada
The responses of density and dielectric logs are formulated in terms if the matrix properties, air-filled porosity and water-filled porosity. Porosity values obtained from logs from borehole...

A Formal Communication Process: Pathway to Improved Policy Making
This paper will examine the efforts made and the steps taken by the U.S. Department of Energy's Office of Civilian Radioactive Waste Management (DOE/OCRWM) to establish and keep open lines...

Two-Way Communication: A Case Study in Improving Public Interactions
Successful public interaction requires several key elements. They include: a non-intimidating forum for exchanging information, two-way communication, advance preparation to identify what...

Using an Engaging Approach to Products to Help Create Long-Term Credibility
A long-term, thorough and engaging public information products plan is essential for supporting interaction between Nevadans and the scientists and staff on the U.S. Department of Energy...

Yucca Mountain Student Tours: Response, Reactions, and Results
In March of 1991, the Yucca Mountain Site Characterization Project (YMP) began providing monthly tours for the general public to visit the Yucca Mountain site. The goal of these tours...

An Inverse Procedure for Estimating the Unsaturated Hydraulic Conductivities of Volcanic Tuffs
A procedure is developed for estimating the hydraulic conductivity function of unsaturated volcanic tuff, using measurements of the sorptivity and capillary pressure functions. The method...

Determination of Water Content in Unsaturated Flow Experiments Using TDR and Capacitance
Electromagnetic techniques have been used for many years for the determination of moisture content in materials. We are adapting two of these techniques to the estimation of moisture in...

Scenario Development for Safety Demonstration for Deep Geological Disposal in Switzerland
A scenario development procedure has been developed that is appropriate to the safety assessment approach chosen by Nagra and to the Swiss regulatory requirements. The procedure is seen...

The MacCSITS Database: A Tool for Curating Samples
Geologic samples are a primary source of data for the Yucca Mountain Site Characterization Project (YMP). The collection and study of the samples is regulated by requirements which mandate...

The Annotated Outline Process for a Mined Geologic Disposal System License Application
The U.S. Department of Energy (DOE) is studying Yucca Mountain, Nevada, as a potential site for a mined geologic repository for high-level nuclear waste. DOE has the responsibility to...

Geologic Repository Licensing Strategy

Thinking Through the Rethinking Report
Congressional action in late 1992 set aside the existing standards for post-closure safety of a possible repository at Yucca Mountain, Nevada. The Environmental Protection Agency (EPA)...

Alternative Strategies—A Means for Saving Money and Time on the Yucca Mountain Project
The United States Department of Energy (DOE) is undertaking studies to determine the suitability of Yucca Mountain (YM) as a potential site for disposal of high-level nuclear waste. Yucca...

Reliability Modeling of an Engineered Barrier System
The Weibull distribution is widely used in reliability literature as a distribution of time to failure, as it allows for both increasing failure rate (IFR) and decreasing failure rate...

Helping a Community Control its Future: Potential Negotiating Packages and Benefits for an MRS Host
The voluntary siting process for the Monitored Retrievable Storage (MRS) facility set forth in the Nuclear Waste Policy Amendments Act (NWPAA) of 1987 provides a potential host community...

Mangling the Models: Real-Life Experiences in Voluntary Siting
Social scientists are accumulating a growing body of research to guide the development of communications models for siting controversial facilities. The models developed by our social...

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...
