Regulatory Views on Seismic and Fault-Displacement Parameters Needed for a Geologic Repository Design
This paper presents the regulatory views of the U.S. Nuclear Regulatory Commission staff on some of the significant issues related to the seismic and faulting design of a geologic repository....
Geometric Models of Faulting at Yucca Mountain
Yucca Mountain, Nevada, is currently being studied as a potential site for a geologic repository of high-level radioactive waste. Alternative conceptual tectonic models are expected to...
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...
GIS Mapping of Earthquake Ground Shaking in San Francisco, California
Severe earthquakes of the last decade in Mexico, Armenia, and the United States have reemphasized the importance of local geologic site conditions in estimating damage and consequent losses....
Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...
Two Shotcrete Lined Tunnels in the United Kingdom
The paper describes two large diameter tunnels recently built in southern England where shotcrete has been used as the primary support. The design methodology is described together with...
Preliminary Assessment of Fault Rupture Hazard at the Yucca Mountain Site Based on Expert Judgement
The judgments of seven earth science experts were elicited to quantify the uncertainties associated with the likelihood of fault displacement through the proposed repository at Yucca Mountain...
Geophysical Investigations of Concealed Faults Near Yucca Mountain, Southwest Nevada
Detailed gravity and ground magnetic data collected along surveyed traverses across Midway Valley, on the eastern flank of Yucca Mountain, Nevada reveal that these methods can be used...
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...
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...
