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...

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...

Accurate Response Analysis of Seismic Distributed Mass Systems
A dynamic analysis technique of distributed mass structures is presented with a combination of the dynamic load factor approach and the dynamic stiffness matrix method. The dynamic stiffness...

An Electronic Specification for the Earthquake Resistance Design of the Highway Bridges in Pennsylvania
An interactive C program for the seismic design of highway bridges in the state of Pennsylvania is described in this paper. The program was developed in C language on a personal computer....

Computer Implementation of Seismic Building Codes
The objective of this work is to implement the provisions of building codes current in the U.S. as well as those of other countries for the seismic resistant design of buildings. The work...

Buckling Optimization of Laminate Stacking Sequence with Strain Constraints
An integer programming formulation for the design of symmetric and balanced composite laminates subject to buckling and strain constraints is presented. The design variables that define...

Structural Optimization to Limit Natural Periods
It is necessary to limit the natural periods of some structures to control their response to dynamic loads. Floor systems with natural periods greater than approximately 0.15 seconds may...

Stiffness Optimization Methods for Lateral Systems of Buildings: A Theoretical Basis
The sizing of the members of the lateral resistance system for multi-story buildings is often controlled by stiffness requirements. In order to achieve economical buildings, it is important...

Parallel Preconditioned Conjugate Gradient Methods for Structural Analysis Problems with Multiple Loadings
This paper describes the use of conjugate gradient method for finite element problems with multiple loading cases. Specifically, we introduce a modified conjugate gradient method for the...

Ground Water: How Contaminated?
It is common knowledge that ground waters, like surface waters, are endangered by pollution from a variety of human activities. Commonsense approaches to the problem are overshadowed by...

Building GIS Relationships Spatially and Politically
This paper advocates that the technological aspect of building a spatial GIS is not the critical factor for a successful multi-participant installation. Rather the political relationships...

Dams for the 21st Century
Water shortages around the world are mounting. Construction of dams, development of groundwater and improvement of irrigation practices are necessary to increase water supplies. Vast quantities...
