Factors Affecting Performance of Vitrified Wasteforms
The acceptability and usefulness of mathematical models for predicting the performance of vitrified wasteforms can be enhanced by their validation using laboratory data generated under...
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...
A Numerical Analysis of Spent Nuclear Fuel Thermal Characteristics
A numerical analysis is presented comparing the thermal behavior of a spent boiling water reactor fuel pin and an electric heating element intended to simulate the fuel pin in an experimental...
Numerically Predicting Horizontally Oriented Spent Fuel Rod Surface Temperatures
A comparison between numerical calculations with use of commercial thermal analysis software packages and experimental data simulating a horizontally oriented spent fuel rod array was...
A Homogeneous Equilibrium Model for Analysis of Spent Fuel Shipping Containers
Transportation of nuclear spent fuel is inevitable over the coming years. However, in order to ensure the safety of such transport, computational models must be established, which are...
Heat Transfer in Vertical Concentric Cylinders in a High Level Nuclear Waste Repository
Modeling free convection heat transfer in an cylindrical annular enclosure is still an active area of research and an important problem to be addressed in the high level nuclear waste...
Structure of Crater Flat and Yucca Mountain, Southeastern Nevada, as Inferred from Gravity Data
Existing gravity data in the vicinity of Yucca Mountain and Crater Flat have been examined to determine if these data support only the caldera model or if they support other geologic models...
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...
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...
Fear of Permanence: The Challenge of Siting Interim Facilities
This paper examines an increasingly urgent and surprisingly difficult task: siting potentially hazardous facilities that are intended to operate for a limited period, such as a Monitored...
The Formation and Economic Impact of Perceptions of Risk Surrounding Nuclear Facilities
This paper summarizes the results of an investigation of factors determining the nature of risk perceptions associated with eleven nuclear facilities and their impact on local economic...
Aperture Characteristics, Saturated Fluid-Flow, and Tracer-Transport Calculations for a Natural Fracture
We used surface-profile data taken with a noncontact laser profilometer to determine the aperture distribution within a natural fracture and found the surfaces and apertures to be isotropic....
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...
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...
Simulating the Behavior of Natural Geological Systems: Sources of Uncertainty and Bias
Post-closure performance assessments are used, in conjunction with controlled laboratory experiments and observations on natural systems, to generate confidence that a radioactive waste...
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...
League of Women Voters Education Fund?Providing a Forum for Public Information and Participation
In March of 1992, the League of Women Voters Education Fund (LWVEF) signed a five-year cooperative agreement with the Department of Energy (DOE) to provide American citizens with information...
A Computer Model for Multiplant Hydroelectric System Simulation
An interactive computer model of a multi-plant hydrothermal electric power generating system has been developed that roughly captures the main features of the British Columbia Hydro system....
