The Oregon Experiment: Public Information and Involvement
Oregon is neighbor to the Hanford Nuclear Site that now has the nation's largest store of radioactive waste. Oregon supports Hanford cleanup, which will require waste transport...

Political Trust's Role in Explaining Nevada Urban Resident's Perceptions of the Proposed Yucca Mountain Repository
This paper examines the key role that political trust plays in explaining repository risk perceptions of urban residents of the Las Vegas metropolitan area. Findings from two surveys of...

Perceived Risk, Real Risk: Scientific Inquiry and Public Concerns About Nuclear Waste Disposal
It is becoming clear that, if we are to solve our nuclear waste disposal problems, we will need to deal seriously with public concerns. Such concerns need to be addressed on their own...

Risk Communication: Translating Technically Complex Information to Facilitate Informed Decision-Making
Based on a review of risk communication and related literature, including policy material, this paper describes the newly revamped risk management program of the Department of Energy's...

Development of a Structural Model to Analyze Public Opinion on a High-Level Radioactive Waste Facility
Studies show that Nevada residents and state officials oppose the proposed high-level radioactive waste repository project at Yucca Mountain. Nevada residents view the Yucca Mountain repository...

Perceived Risk, Trust in Government, and Response to Repository Siting in the United States
Conflicts over the siting of high-level radioactive waste repositories have been intense and unrelenting. Public and state opposition to implementation of the U.S. Nuclear Waste Policy...

Major Results of Gravity and Magnetic Studies at Yucca Mountain, Nevada
About 4,000 gravity stations have been obtained at Yucca Mountain and vicinity since the beginning of radioactive-waste studies there in 1978. These data have been integrated with data...

Geophysical Borehole Logging in the Unsaturated Zone, Yucca Mountain, Nevada
Borehole geophysical logging for site characterization in the volcanic rocks at the proposed nuclear waste repository at Yucca Mountain, Nevada, requires data collection under rather unusual...

Dry Drilling and Coring Development for Unsaturated Zone Studies
Two areas of major difficulty associated with characterization of any unsaturated zone are the conventional drilling and coring processes used to acquire the samples. These processes are...

Geologic Sample Handling and Logging at Apache Leap, Arizona
Early in 1990, the Yucca Mountain Project Office (Project Office; presently the Yucca Mountain Site Characterization Project Office) of the U.S. Department of Energy (DOE) completed two...

Field Investigations for Seismic Effects on Mechanical and Geohydrologic Response of Underground Structures in Jointed Rock
An exploratory Seismic Rock Mechanics research program has been initiated by the U.S. Nuclear Regulatory Commission at the Center for Nuclear Waste Regulatory Analyses (CNWRA) to study...

Boundary Integral Methods for Unsaturated Flow
A boundary integral equation method (BIEM) is described for numerical analysis of quasilinear steady unsaturated flow in homogeneous material. The applicability of the exponential model...

Analysis of Solute Transport in an Intermediate-Scale Unsaturated Flow Experiment
A simplified stochastic model was derived and applied to two unsaturated flow experiments conducted in an intermediate-scale caisson. Parameters for the flow and transport models were...

Theory of Matrix and Fracture Flow Regimes in Unsaturated, Fractured Porous Media
The flow behavior of a two-dimensional, unsaturated fracture-matrix system is characterized by a critical flux q_f^*...

Effect of a Low-Permeability Layer on Calculated Gas Flow at Yucca Mountain
Yucca Mountain is being studied to determine its suitability as a location for a high-level nuclear waste repository. The mountain is a steep-sided linear ridge which is underlain by a...

Performance Assessment: The Bridge Between Regulatory Decision-Making and Scientific Uncertainties
NRC has the responsibility for evaluating the license application for a repository against the regulations it has promulgated. Performance assessment is the bridge between regulatory decision-making...

Key Scientific Issues for Near-Field Performance Assessment
This paper reviews key scientific issues related to the performance assessment of engineered barrier systems. In contrast to the inherent uncertainties associated with inhomogeneous geologic...

Advances in the Study of Far-Field Phenomena Affecting Repository Performance
Studies of far-field phenomena affecting repository performance have focussed on the role of fractures and other heterogeneities in the potential transport of radioactive solutes from...

Process and Criteria for Valuation of the Ground-Water Flow Models in the OECD/NEA International Stripa Project
In 1986, the Site Characterization and Validation (SCV) Program was initiated as part of Phase III of the OECD/NEA International Stripa Project. The principal intent of the SCV Program...

Some Conclusions from a Biospheric Model Validation Study (BIOMOVS)
BIOMOVS (BIOspheric MOdel Validation Study) is an international co-operative effort to test biospheric models designed to calculate the environmental transfer and bioaccumulation of radionuclides...
