Empirical Prediction of Strong Ground Motion
In 1982, we published equations for the prediction of various measures of ground motion as a function of earthquake magnitude, distance from the earthquake rupture, and site geology. Many...

This paper outlines the guidance provided to the U.S. Department of Energy by the Nuclear Regulatory Commission (NRC) staff in its Staff Technical Position (STP) on appropriate investigations...

Photogeologic Reconnaissance of X-Tunnel at Little Skull Mountain
An underground structure known as X-tunnel was investigated for the viability as an underground deep based missile system that included the capability to maintain survivability following...

Science Education Beyond the Classroom
The Yucca Mountain Site Characterization Project (YMP) sponsors a variety of classroom-oriented projects and activities for teachers who request them. Also available, though, are extra-curricular...

The Sellafield Repository Project as Seen by the Public—A Comparison of Research Techniques
To see one's organisation through the eyes of others, to monitor that view and to amend it if necessary, is the primary role of the public relations and public affairs function in an establishment....

Selection of the Initial Access for the Yucca Mountain Exploratory Studies Facility
This paper describes the activities undertaken to examine relevant factors and select the initial access for the Yucca Mountain exploratory studies facility. To aid their decision, the...

Is An Institute for the Study of High-Level Radioactive Waste Disposal Needed in Southern Nevada?
This paper examines key questions about the need for a formal institute that would study storage and disposal concepts for high-level radioactive waste (HLW) in the United States and throughout...

The Nagra-DOE Cooperative Project
Tne Nagra-DOE Cooperative (NDC-I) research program was sponsored by the U.S. Department of Energy (DOE) through the Lawrence Berkeley Laboratory (LBL), and the Swiss Nationale Genossenschaft...

Findings of the Secretary of Energy Advisory Board Task Force on Radioactive Waste Management
Secretary of Energy James D. Watkins created the Task Force on Radioactive Waste Management in April 1991. He asked the group then to recommend measures the Department might take to strengthen...

Structural Character of the Ghost Dance Fault, Yucca Mountain, Nevada
Detailed structural mapping of an area that straddles the southern part of the Ghost Dance Fault has revealed the presence of several additional subparallel to anastomosing faults. These...

Sensitivity and Probabilistic Analyses of Ground Water Travel Time in a Fractured and Variably-Saturated Geologic Medium
This paper presents a method for sensitivity and probabilistic analyses of performance of a hypothetical nuclear waste repository located in a layered, fractured, and variably-saturated...

Analyses of Natural Resources in 10 CFR Part 60 as Related to Inadvertent Human Intrusion
The purpose of this paper is to examine the intent of the regulatory language of the portions of 10 CFR Part 60 which deal with considerations of the natural resources of a proposed geologic...

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...

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...

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...
