Solute Transport Characteristics of Fractured Dolomite in Southern Nevada, USA
Recirculating tracer tests in fractured Cambrian dolomite beneath the Amargosa Desert revealed (1) and 83-percent increased in apparent dispersivity resulting from a two-percent increase...

Radionuclide Transport in Fractured Media
Until recently, the classical advective-dispersive transport equation was considered to be an adequate model for describing the motion of a solute (e.g. radionuclides) in porous and fractured...

Photothermal Deflection Spectroscopy Investigations of Uranium Electrochemistry
Photothermal deflection spectroscopy (PDS) has been successfully applied to the study of uranium oxide electrochemistry. A brief description of PDS and preliminary results that demonstrate...

Summary of Revised Potentiometric-Surface Map for Yucca Mountain and Vicinity, Nevada
The revised map for the potentiometric surface of the uppermost saturated zone in Tertiary volcanic rocks at Yucca Mountain, Nevada, is based mainly on 1988 water levels. Refinement of...

Isotopic Evidence of Complex Ground-Water Flow at Yucca Mountain, Nevada, USA
Strontium isotopes (expressed as per mill deviation from mean sea water, ?⁸⁷Sr) reflect interaction between ground water and the aquifer through...

Development of the Office of Civilian Radioactive Waste Management's Self-Assessment Program
This paper describes the development and implementation of the Self-Assessment (SA) Program of the Office of Civilian Radioactive Waste Management (RW). The basis for RW's SA program is...

Geometric Analyses of Alternative Models of Faulting at Yucca Mountain, Nevada
Realistic cross section tectonic models must be retrodeformable to geologically reasonable pre-deformation states. Furthermore, it must be shown that geologic structures depicted on cross...

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...

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...

Isotopic and Trace Element Variability in Altered and Unaltered Tuffs at Yucca Mountain, Nevada
Reference stratigraphic sections near Yucca Mountain, Nevada were established and sampled in outcrop areas where the volcanic rocks have been minimally altered. Isotopic and trace element...

Lead Isotopic Composition of Paleozoic and Late Proterozoic Marine Carbonate Rocks in the Vicinity of Yucca Mountain, Nevada
Paleozoic and Late Proterozoic marine carbonate rocks (limestones, dolomites, and their metamorphic equivalents) cropping out in the vicinity of Yucca Mountain contain lead with an isotopic...

Isotope-Geochemical Investigations of Volcanic Rocks in the Vicinity of the Radiochemical Plant Mayak (Russia)
Russian programmes on radioactive waste management consider a possibility to organize an underground laboratory and subsequently an underground repository for intermediate- and high-level...

Mercury Porosimetry Studies on a Natural Fracture
Mercury porosimetry techniques were used to study the effects of stress on the capillary pressure characteristics of a single natural fracture. In addition, permeability measurements were...

Small-Scale Behavior of Single Gravity-Driven Fingers in an Initially Dry Fracture
Experiments investigating the behavior of individual, gravity-driven fingers in an initially dry, rough-walled analog fracture are presented. Fingers were initiated from constant flow...

Modeling Gravity-Driven Fingering in Rough-Walled Fractures Using Modified Percolation Theory
Pore scale invasion percolation theory is modified for imbibition of wetting fluids into fractures. The effects of gravity, local aperture field geometry, and local in-plane air/water...

Resource Leveling Based on the Modified Minimum Moment Heuristic
CPMLevel is an MS Windows computer program that utilizes the minimum moment algorithm to smooth the histogram of a resource in both traditional and overlapped CPM networks. It has interactive...

A Rezoning Procedure for Finite Element Analysis of Rubber-like Materials
In this paper, we propose a rezoning procedure for finite element analysis of rubber-like materials. Rezoning procedures connect the distorted mesh and the newly created and undistorted...

A Finite Difference Approach to the Modelling of Thick Bridge Decks
The finite difference method, although well known as an efficient numerical method, was applied in the past, in the case of slabs, only for the solution of thin slabs. In the present study,...

Object-Oriented Finite Element Modeling
The present paper studies the suitability of object-oriented modeling strategies for problems of structural mechanics. After a general discussion of the topic, special emphasis is put...

Research of the Limit Function About Imperfection and the Approximately Calculating Method of the Internal Forces of Hyperbolic Cooling Tower
The authors use the finite elemental program, which made by themselves and makes use of finite element method with rotational shell, to calculate the deformation in hyperbolic cooling...
