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...

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...

Plutonium and Minor Actinide Transmutation by Long Irradiation in LWR
An investigation was made on the conceptual possibility of burning in a thermal reactor MOX fuel together with special pins containing plutonium, minor actinides and long-lived fission...

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...

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...

Thermal-Hydraulic Analyses of Molten Glass in a Joule-Heated Melter
Physical modelling using glycerine and three-dimensional mathematical modelling were executed to study temperature and flow profiles of molten glass in the melter for the vitrification...

Stochastic Modelling of Groundwater Flow at the WIPP Site
A stochastic approach to modelling the groundwater flow in the vicinity of the WIPP site in New Mexico is described. A geostatistical model of the transmissivity of the Culebra dolomite...

Water Quality Model of the Chicago Waterway
In 1992, the Metropolitan Water Reclamation District of Greater Chicago (the District) developed a QUAL2E water quality model of the Chicago waterway and Upper Illinois waterway. The model...

Hydrologic Forecasting—What are the Issues?
The paper briefly describes hydrologic forecasting techniques that are being used today and raises issues that should be addressed as new hydrologic forecast systems are developed and...

The Law of the River: Policy Expression
The need to accurately represent the law of the Colorado river has heretofore precluded the use of any general purpose river basin simulation model. In order to overcome the inflexibility...

RSS: A Construction Kit for Visual Programming of River Basin Models
With the ever increasing pressure on environmental resources, there exists strong interest in river basin models which can be used to simulate proposed policy alternatives. Traditionally,...

Optimal Planning of Combined Sewer Rehabilitation
The need to rehabilitate many of the existing sewer systems to keep them operational is evident. The development of a rehabilitation plan that optimizes the use of funds is the first step...

Empowering Stakeholders Through Simulation in Water Resources Planning
During the past two years, researchers at the University of Washington (UW) have had the unique opportunity to facilitate and observe the development of drought planning activities associated...

The Role of Object Oriented Simulation Models in the Drought Preparedness Studies
One of the major activities in the U.S. Army Corps of Engineers, Drought Preparedness Studies (DPS) has been the development of water resource simulation models for each study site. This...

Multiparty Model Development Using Object-Oriented Programming
The Massachusetts Water Resources Authority (MWRA) has taken advantage of recent advances in object oriented programming to build a flexible input and output model of its water supply...

Citizen Participation in Water Supply System Planning and Management
The Water Supply Citizens Advisory Committee (WSCAC) is a unique citizens group. Although it is funded by the Massachusetts Water Resources Authority (MWRA), it has a paid staff who are...

Flow Investigation for Landfill Leachate
A two-dimensional unsteady-state moisture flow model has been developed in order to describe the leachate flow process in a landfill. The unsteady variation of leachate mound head has...
