Predicted Thermal and Stress Environments in the Vicinity of Repository Openings
An understanding of the thermal and stress environment in the vicinity of repository openings is important for preclosure performance considerations and worker health and safety considerations...
Rethinking the Economic factors of Centralized Spent Fuel Storage
The economics of centralizing the storage of spent fuel at a single site, as opposed to continued storage at over 100 reactor sites, has been the subject of several recent analyses. Most...
Industry Experience and Programs that Benefit the Monitored Retrievable Storage (MRS) Facility Design
The design objectives and criteria for an MRS must be responsive to the needs and concerns of the public and the industry. It is shown here that to the maximum extent, existing industry...
Design and Operation of a Monitored Retrievable Storage Facility Using NUHOMS? Technology
The NUHOMS dry storage system for spent fuel is now in use at two Independent Spent Fuel Storage Installations (ISFSIs) and a third is under construction. This system can be used for economical...
Economic and Technical Advantages of High-Temperature Processes in High-Level Radioactive Waste Management
The estimated waste management costs incurred for the three principal waste forms produced by reprocessing spent fuel are compared from a theoretical economic standpoint. The cost of vitrifying...
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...
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...
Regulatory Requirements and Long-Term Repository Host Rock Performance
The regulatory requirements governing the disposal of high-level radioactive wastes in mined geologic repositories acknowledge the long-lived nature of the wastes and require the consideration...
Potential Uses of Lead in Nuclear Waste Disposal
In order for lead to be considered as a nuclear waste packaging material, it must be shown that it has adequate corrosion resistance, and that it does not degrade the properties of other...
Risk Assessments for the Design of Subsurface Openings
A probabilistic approach was introduced to assess the risk of structural instability due to rock joint systems in rock mass, where subsurface openings are excavated, such openings as shafts,...
Determination of Cost Effective Waste Management System Receipt Rates
A comprehensive logistics and cost analysis has been carried out to determine if there are potential benefits to the high-level waste management system for receipt rates other than the...
GA-4/GA-9 Honeycomb Impact Limiter Tests and Analytical Model
General Atomics (GA) has a test program underway to obtain data on the behavior of a honeycomb impact limiter. The program includes testing of small samples to obtain basic information,...
Modelling of Excavation, Thermal Loading and Bentonite Swelling Pressure for a Waste Repository
For the performance assessment of a future nuclear waste repository, the excavation of the tunnel and deposition hole, thermal loading from waste heat release and the swelling pressure...
The Radiological Capacity of Transport Casks Loaded in a 2-Region Non-Uniform Pattern
The radiological capacity of spent fuel storage and transport casks can be increased by the use of non-uniform cask loading. There are many possible combinations of spent fuel burnup and...
Toward Linking Demographic and Economic Models for Impact Assessment
One of the objectives of the Yucca Mountain Project, in Southern Nevada, is to evaluate the effects of the development of a high-level nuclear waste repository. As described in the Section...
Forecasting Behavioral Response to a Repository from Stated Intent Data
To forecast repository-induced behavior from surveys of behavioral intention, we develop a model of the relation between stated intent and actual propensity. This model relies heavily...
Circuitous Routings: Integration of Public Acceptability with Technical and Economic Feasibility
Public acceptance of agency plans for shipment of radioactive wastes to disposal facilities may be critical to efforts to site geologic repositories. Local and state participation in route...
Some Political Logistics of Nuclear Waste
The need for a centralized, federal, interim storage facility for nuclear waste, or MRS, alledgedly has become more urgent because the date for the opening of the permanent repository...
Development of a Pavement Design Expert System
The latest edition of the Guide for Design of Pavement Structures was published by the American Association of State Highway and Transportation Officials in 1986. This edition of the Guide...
Knowledge Representation for Bridge Design
An implementation of a frame-based knowledge representation language (KRL) for development of expert system applications in highway bridge design is presented. The frame-based KRL is used...
