Inference of Moisture Content in Unsaturated Media Using Ultrasonics
This study focuses on the ability of commercial ulltrasonics equipment to determine the moisture content in unsaturated media. We are interested in the possible application of this technology...

Automatic Calibration of 3D Finite Differences Model Parameters? Application to the Finnsjon Site (Sweden)
Calibration of 3D finite difference model parameters is usually carried out using a noon-automatic 'manual' procedure until observed heads, for instance, are simulated with a sufficient...

Channel Network Models for Solute Migration and Dispersal
We introduce a class of channel-network models for solute migration and dispersal in saturated rock. In discussing the behaviour of any dispersive process it is necessary to compare and...

A Comparison of Geostatistically-Based Inverse Techniques for Use in Performance Assessment Analyses at the WIPP Site?Results from Test Case No. 1
The groundwater flow pathway in the Culebra Dolomite aquifer at the Waste Isolation Pilot Plant (WIPP) has been identified as a potentially important pathway for radionuclide migration...

Fission Product Distribution in Nuclear Test Cavities/Chimneys
When a nuclear device is exploded, residual radioactive material is distributed throughout the resulting underground cavity and rubble chimney. Refractory materials are more concentrated...

Detachment Faults?Regulatory Implications for the Yucca Mountain Site
Site characterization investigations at the Yucca Mountain site, Nye County, Nevada consist of a combination of scientific data collection and analyses, and compliance with regulatory...

Seismic Reflection Profiling: Essential Geophysical Data for Yucca Mountain, Nevada
Yucca Mountain, Nevada, consists of a thick sequence of ashflow tuffs and lavas fractured into intact blocks with east-dipping strata, marginal broken zones characterized by dense faulting...

Characterization of Porosity in Support of Mechanical Property Analysis
Previous laboratory investigations of tuff have shown that porosity has a dominant, general effect on mechanical properties. As a result, it is very important for the interpretation of...

Large-Scale in Situ Heater Tests for Hydrothermal Characterization at Yucca Mountain
To safely and permanently store high-level nuclear waste, the potential Yucca Mountain repository site must mitigate the release and transport of radionuclides for tens of thousands of...

Micromechanics of Deformation in Topopah Spring Tuff, Yucca Mountain, Nevada
Samples of Topopah Spring tuff from Yucca Mountain, Nevada have been tested and analyzed. Laboratory tests conducted include standard uniaxial and triaxial compression tests, and special...

Core and Reaming Bit Studies in Yucca Mountain Tuffs
The Site Characterization Project is a major part of the work in determining the suitability of Yucca Mountain as a potential high level waste repository. Over 100 exploratory drill holes...

Experimental Studies to Calibrate Unsaturated Flow Models
Work is described that has been designed to serve as a laboratory calibration of numerical models for unsaturated flow studies. The experiment size is configured large enough that the...

Durability Testing of the High-Capacity GA-4/GA-9 Trailer
General Atomics (GA) is under contract to the US Department of Energy (DOE), Idaho Field Office, to develop two legal-weight truck from-reactor spent-fuel shipping casks with trailers....

Application of Indicator Geostatistics to the Gorleben Data Set
This paper describes a trial application of Indicator geostatistical methods to borehole data from the Gorleben site. Indicator variograms have been estimated from the site data and fitted...

Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....

Design of Pile Foundations
This handbook, Design of Pile Foundations, provides information on foundation exploration and testing procedures, load test methods, analysis...

Dynamic Analysis and Design Considerations for High-Level Nuclear Waste Repositories
This proceedings, Dynamic Analysis and Design Considerations for High-Level Nuclear Waste Repositories, consists of papers presented at the...

A Structural Analysis System for Prestressed Concrete Bridges and its Application on the Interurban Express-Way Project in SEOUL
In this paper, the importance of the structural analysis in accordance with the construction progress was emphasized to accurately predict the structural behavior of prestressed concrete...

Computer Analysis of Cable-Stayed & Suspension Bridges
The finite element structural analysis of long span bridges is an area of research that has been studied within the past thirty years since the development and emergence of the digital...

Modeling Beam Torsion in Prestressed Concrete Box Beam Bridges
This paper briefly summarizes the development of a specialized finite element model capable of predicting the elastic and inelastic behavior of beam-slab type prestressed concrete spread...
