Flow and Transport Around a Noncontinuous Horizontal Layer at Yucca Mountain
Computer simulations were used to examine the effect of a noncontinuous horizontal layer on the flow field and contaminant transport of a simplified conceptual model. The domain consisted...
Unsaturated Flow Through a Variable Aperture Fracture in Topopah Spring Welded Tuff
The role of fractures in unsaturated flow through welded and nonwelded tuffaceous rocks is a fundamental question being addressed in performance assessment activities for the Yucca Mountain...
Transportation of Radioactive Materials Routing Analysis: The Nevada Experience
In 1987, the Nevada State Legislature passed a Bill requiring the Nevada Department of Transportation to develop and enforce a plan for highway routing of highway route controlled quantity...
Mechanistic Interpretation of Glass Reaction: Input to Kinetic Model Development
Actinide-doped SRL 165 type glass was reacted in J-13 groundwater at 90?C for times up to 278 days. The reaction was characterized by both solution and solid analyses. The glass was seen...
Modelling Studies for the Assessment of the Advanced Cold Process Canister
The Advanced Cold Process Canister (ACPC) is a new concept for the encapsulation of spent nuclear fuel for geological disposal. It consists of steel canister encased in a copper overpack....
Validation of Source-Term Models Using Natural Analogues
A comparison is made between the predicted distribution of copper calculated by the AREST source-term code and the measured profiles for copper surrounding a bronze cannon that was emplaced...
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...
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...
