Investigation of Burnup Credit Allowance in the Criticality Safety Evaluation of Spent Fuel Casks
The payloads of present generation spent fuel casks are constrained by a criticality design basis that assumes loading with unirradiated fuel. This presentation discusses work in progress...
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...
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,...
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...
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,...
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...
Creatively Cost Sharing a Large Flood Control Dam
The passage of Public Law 99-662 in November of 1986, commonly known as the Water Resources Development Act of 1986, added a new dimension to Federal development of water resource projects....
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...
Restoration of a Buttress Dam
Inspections of Morris Shepard Dam on the Brazos River in Texas revealed serious defects in the dam and its foundation. Piezometric pressures below the spillway buttresses greatly exceeded...
Morris Sheppard Dam: A Rational Approach to Stability Analysis
This paper details the excessive foundation piezometric conditions found during a routine five-year inspection, and presents the results of backfigured stability analysis of a critical...
Possum Kingdom Lake: The Impact of Releases for Fish and Wildlife
Possum Kingdom Lake is a 570,000 acre-foot reservoir on the Brazos River in Palo Pinto County, Texas, owned and operated by the Brazos River Authority (BRA). In 1985 the BRA applied to...
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...
Montgomery Point Lock and Dam Entrance to the McClellan-Kerr Arkansas River Navigation System
The McClellan-Kerr Arkansas River Navigation System has experienced a steady and positive increase in use. However, in the last 10 years changing conditions along the Mississippi River...
Benefits from Floodplain Management Activities in Relation to Operating South Holston Dam
Floodplain management activities have primarily been directed toward avoiding floodplain siting where practical; where siting is unavoidable, elevating structures, facilities, or equipment...
