Modeling of Strongly Heat-Driven Flow Processes at a Potential High-Level Nuclear Waste Repository at Yucca Mountain, Nevada
Two complementary numerical models for analyzing high-level nuclear waste emplacement at Yucca Mountain have been developed. A vertical cross-sectional (X-Z) model permits a realistic...

Modelling Colloidal Transport of Radionuclides Through Porous Media
General acknowledgement of the potential role of colloids in enhancing radionuclide transport has prompted the preliminary development of a mechanistic colloid transport model as part...

Are Colloids Important for Transport Rate Assessment of Radionuclides? A Microscopic Modeling Approach
Understanding the transport phenomena of radionuclides migrating through weakly-permeable rocks forms an essential part of far-field safety assessment studies. Colloidal matter can be...

Sensitivity and Probabilistic Analyses of Ground Water Travel Time in a Fractured and Variably-Saturated Geologic Medium
This paper presents a method for sensitivity and probabilistic analyses of performance of a hypothetical nuclear waste repository located in a layered, fractured, and variably-saturated...

Experience in Modeling for Environmental Physics and Biogeochemistry
This report is a short review of the author's personal experience on phys.-math. and system-logical modeling of migration and transport processes (MTP) of radionuclides, trace-elements...

Review and Selection of Unsaturated Flow Models
The Civilian Radioactive Waste Management System Management and Operating Contractor (CRWMS M&O) is conducting a thorough review and evaluation of existing flow and transport models....

Development of 3-D Lithostratigraphic and Confidence Models at Yucca Mountain, Nevada
Computerized three-dimensional geologic models of potential high-level nuclear waste repositories such as Yucca Moutain, Nevada, are important for visualizing the complex interplay of...

A Public Involvement Planning Model for the Civilian Radioactive Waste Management Program
Substantive and early involvement of affected governments, interested parties, and the public in the decisionmaking process of the Office of Civilian Radioactive Waste Management (OCRWM)...

Modeling Storage Behavior in a Fractured Rock Mass
To represent single bore hole injection tests in fractured rock masses, a transient model has been implemented, based on a three dimensional stochastic description of the fracture network....

Connectivity and the Continuum Approximation in Fracture Flow Modeling
The continuum assumption is frequently made when modeling flow in fractured media. The approach presented in this paper helps evaluating the validity of such an assumption. Two indices...

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...

An Object Oriented Relational Database for Assessing Radioactive Material Transport
EnviroView is an object oriented relational database used for inventory control and monitoring locations of radioactive and toxic materials. Visual images of local sites, building locations,...

Characterizing the Hydrogeologic Framework of the Death Valley Region, Southern Nevada and California
Three-dimensional (3-D) hydrogeologic modeling of the complex geology of the Death Valley region requires the application of a number of Geoscientific Information System (GSIS) techniques....

The Effect of Certain Assumptions on the Number and Type of Spent Fuel Casks Required 1998-2000
The Office of Civilian Radioactive Waste Management M&O contractor is determining the number of spent fuel transportation cask systems required to transport fuel from reactors...

Reliability Modeling of an Engineered Barrier System
The Weibull distribution is widely used in reliability literature as a distribution of time to failure, as it allows for both increasing failure rate (IFR) and decreasing failure rate...

Experimental Synthesis of Crystalline Matrices Based on Ce, Ba, Sr Zirconates for Immobilization of High-Level Radioactive Actinides
Experimental investigations are carried out at the Radium Institute to create different by their properties crystalline matrices, alternative to SYNROC, for incorporation of partitioned...

Modeling Adsorption of Mixtures of Radionuclides by Zeolitized Tuff
Multi-solute sorption isotherms were measured using 'nonscents', a zeolitized volcanic tuff material from Southeast Arizona. Isotherms for the three constituent binaries, Sr-Co, Cs-Sr...

Modeling of Saturated Zone at Yucca Mountain, Nevada
This paper presents preliminary results of groundwater modeling of the saturated zone in the vicinity of Yucca Mountain. The analysis used both a regional (approximately 250 ? 250 km)...

Functional Analysis of the Exploratory Studies Facility
This paper discusses the development of the 'Physical System Requirements-Exploratory Studies Facility' (PSR-ESF) document. Based on a functional analysis approach, this document includes...

Integrated Test Evaluation Decision Framework for the Yucca Mountain Project
An Integrated Test Evaluation decision framework and computer model were developed to help prioritize site-characterization tests at Yucca Mountain. An initial application of the framework...
