MARNIE, a Near Field Transport Model for Radioactive Waste Repositories
The long term safety of a final repository for radioactive waste disposal has to be demonstrated. A number of scenarios can be postulated that could lead to a considerable release of radionuclides...

Conclusions from Project-90 With Regard to a Regulatory Framework
A five year performance assessment program, Project-90 [1], has been concluded by the Swedish Nuclear Power Inspectorate, SKI. The project was defined to develop independent assessment...

CALIBRE and CRYSTAL: Near-field and Geosphere Models for Project-90
A new near-field model (CALIBRE) and a fractured geosphere model (CRYSTAL) have been developed in support of the Swedish Nuclear Power Inspectorate's Project-90 safety assessment...

Status of WIPP Compliance with EPA 40 CFR 191, December 1990?SAND90-2424C
Sandia National Laboratories is conducting performance assessments for the United States Department of Energy to use in evaluating compliance of the Waste Isolation Pilot Plant with EPA...

Testing of Materials and Scale Models for Impact Limiters
Aluminum Honeycomb and Polyurethane foam specimens were tested to obtain experimental data on the material's behavior under different loading conditions. This paper reports...

Three-Dimensional Groundwater Flow Modelling for a Potential Repository Site
In Finland site investigations are carried out at five places in order to find a suitable site in the Finnish bedrock for a repository for spent nuclear fuel. The aim is to model the bedrock...

Estimating Geochemical Behavior of Cocnretes to be Placed at Yucca Mountain
The interactions of J-13 water with cementitious materials were examined at 25?C using the geochemical code EQ3NR/EQ6. Results of the modeling suggested the following conclusions: (1)...

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...

A Prototype of the Uniform Building Code Using Hypertext
The earthquake section of the Uniform Building Code has been implemented using the hypertext technology. The information was broken down into many interrelated nodes. Figures were scanned...

Visualizing the Performance of Structural Optimization Processes
Graphical constructions are discussed that enable the performance of iterative structural optimization processes to be evaluated visually. The first, a basins of attraction construction,...

Computer-Based Interactive Design for Prestressed Concrete Structures
Prestressed concrete structures can provide a highly desirable solution for many structural applications because the designer gains control over several additional parameters as compared...

A PC-CAD System for Prefabricated Steel Bridges
A microcomputer-aided analysis and design system for prefabricated steel bridges is presented in this paper. The system was customized to perform all the required engineering to analyze,...

Computerized Bridge Monitoring System
Research at the University of Connecticut has generated a full scale vibrational monitoring system for installation on a Connecticut bridge. The monitoring system consists of a field computer...

Integrated Structural Engineering Solution for Design, Drafting and Analysis
Computervision Corporation is a leading CAD/CAM/CAE vendor that offers a complete integrated structural solution to customers. This structural solution allows customers to manage intricate...

Integrated Structural Design Software in the IBM Architecture & Engineering Series
The Architecture and Engineering Series (AES) software by IBM is a high function, fully integrated design, drafting, and information system. The system provides three dimensional geometry...

Integration of CAD and Structural Engineering for Building Design
Many design/build contractors have publicized successes using three-dimensional (3D) computer-aided-design (CAD) models. Structural engineers contribute equipment support structures as...

Computer-Aided Structural Analysis
Finite Element Methods and other numerical techniques are often taught nowadays in the undergraduate Structural Analysis courses. Commercial, structural computer programs are becoming...

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...

COMBAT.PC; a New Windows-Based Tool for Three-Dimensional Dynamic Analysis of Multi-storied Building Structures
By some accounts, analytical capability without the power of visualization is little productive; visualization is the tool that will turn computational power into practical results. COMBAT.PC...

MINLP and MILP Strategies for Discrete Sizing Structural Optimization Problems
We address an important practical problem of optimum structural design in the presence of discrete sizing constraints. In addition, the topology of the structure may vary as well. The...
