Diffusion Coefficients and Hydraulic Conductivity in Unsaturated Hanford Soils and Sediments
Two groundwater transport parameters of some Hanford formation materials, the hydraulic conductivity and the diffusion coefficient, were measured to aid in predicting contaminant migration....
Two Citizen Task Forces and the Challenge of the Evolving Nuclear Waste Siting Process
Siting any nuclear waste facility is problematic in today's climate of distrust toward nuclear agencies and fear of nuclear waste. This study compares and contrasts the siting...
Public Attitudes Toward a High-Level Nuclear Repository: Implications on the Prospects of Successful Siting
Recent legislation enacted by the State of Nevada makes it illegal to store high-level nuclear waste (HLNW) within state, posing a serious threat to the federal government's...
Hedonic Price Theory: Concept and Applications
Direct and indirect techniques are being used to estimate economic consequences of proximity to existing or proposed public facilities. The hedonic price theory, an indirect technique,...
Concrete Cask Storage Technology
The paper presents the design and operation of the new dry storage system for nuclear waste. The system was designed by complete nuclear, thermal-hydraulic and structural analysis to the...
Optimizing the Spent Fuel Transportation Cask for Spent Fuel Age and Burnup: A Preliminary Analysis
The U.S. Department of Energy (DOE) has been assigned responsibility for managing the nation's spent nuclear fuel (SNF). Because of the large quantity of SNF to be moved,...
Transportation Cask Life Cycle Cost Uncertainty Analysis
This paper demonstrates an uncertainty analysis methodology using random sampling. This methodology has been applied to a nuclear waste transportation code, and several transportation...
Analysis of RADTRAN Transportation Model
The RADTRAN computer model, used to estimate the risks of transporting waste to a high-level repository, is critically reviewed. Ignoring high consequence accidents, human error, sabotage,...
Accident Analyses in Fulfillment of the Requirements of the National Environmental Policy Act and Their Relationship to the Packaging and Testing Requirements of the Nuclear Regulatory Commission
In planning its Transportation Program, the Office of Civilian Radioactive Waste Management must address two fundamental questions: (1) To what extent are the reasonably foreseeable significant...
Requirements for Controlling a Repository's Releases of Carbon-14 Dioxide; The High Costs and Negligible Benefits
A repository excavated within the unsaturated zone may release carbon(C)-14 dioxide in amounts that exceed limits imposed by the Environmental Protection Agency (EPA) and the Nuclear Regulatory...
Postclosure Safety Assessment of Radioactive Waste Disposal Systems: Current State of Understanding and International Consensus
Approximately ten years have passed since the first comprehensive safety assessments of radioactive waste disposal systems appeared. Through intensive efforts in practically all countries...
Method for Determining the Fuel Contribution to the Source Term in Trasnport Casks
A comprehensive source term characterization methodology has been developed for the determination of the fuel contribution to the potentially releasable radioactivity in spent fuel shipping...
Implications of the New Radiation Exposure Limits on Space Station Freedom Crews
Spaceflight unavoidably increases the exposure of astronauts to natural ionizing radiation. Any increase in radiation exposure increases the risk of contracting cancer or inducing genetic...
Artificial Gravity: Human Factors Design Requirements
A major challenge of manned spaceflight is to assure the health, well-being and performance of the space inhabitants. As man ventures beyond Earth's orbit to settle the Moon,...
Probable Impacts of Space Operations on Air Force Civil Engineering
Consider the bridge from today's space programs and systems to tomorrow's space reality. Current space policy is revoluntionary in nature. Selected space related...
Benefits of Radioisotope Thermoelectric Generators
Since the 1960's the United States has had the capability to reach beyond the planet Earth with the aid of satellites and interplanetary space probes. As probes such as the...
Stormwater Management: Detention in Illinois
In 1987 the Illinois Department of Transportation contracted the Northeastern Illinois Planning Commission (NIPC) to perform a study to determine the effectiveness of the current accepted...
Sediment Management Challenges of the Red River Waterway Project
The Red River Waterway project consists of channel stabilization and construction of navigation locks and dams to provide a 9 foot minimum depth for a distance of approximately 236 miles,...
The Impact of the Morris Sheppard Dam Experience on Buttress Dam Safety Evaluations
The stability problems encountered at the Morris Sheppard Dam have had an impact upon the Federal Energy Regulatory Commission's (FERC) dam safety program. This paper describes...
Estimating Earthquake Hazard of Municipal Water Systems
This paper uses the City of Memphis as a case study to present the seismic hazard evaluation of a municipal water delivery system. The horizontal peak bedrock accelerations resulting from...
