The Influence of Long Term Climate Change on Net Infiltration at Yucca Mountain, Nevada
Net infiltration and recharge at Yucca Mountain, Nevada, a potential site for a high level nuclear waste repository, are determined both by the rock properties and past and future changes...
TVO-92 Safety Analysis of Spent Fuel Disposal
Spent fuel from the TVO I and TVO II reactors is planned to be disposed of in a repository to be constructed at a depth of about 500 meters in crystalline bedrock. The fuel will be encapsulated...
The DOE Tansportation Management Division's Motor Carrier Evaluation Program
The movement of hazardous materials and wastes over the nation's highways by commercial motor carriers presents a challenge for the purchaser of transportation services. During the next...
Investigation of Fracture-Matrix Interaction: Preliminary Experiments in a Simple System
Paramount to the modeling of unsaturated flow and transport through fractured porous media is a clear understanding of the processes controlling fracture-matrix interaction. As a first...
Preliminary Characterization of Materials for a Reactive Transport Model Validation Experiment
The geochemical properties of a porous sand and several tracers (Ni, Br, and Li) have been characterized for use in a caisson experiment designed to validate sorption models used in models...
Groundwater Transport Characteristics of Fracture Zones in a Granite Batholith
Major low-dipping fracture zones are the dominant pathways for the large scale circulation of groundwater through the Lac du Bonnet granite batholith of southeast Manitoba, Canada. The...
AREST: The Next Generation
Simple mass transport models using constant boundary conditions at the waste form surface and at the host rock boundary do not always results in realistic predictions of the performance...
Drift Emplaced Waste Package Thermal Response
Thermal calculations of the effects of radioactive waste decay heat on the potential repository at Yucca Mountain, Nevada, have been conducted by the Yucca Mountain Site Characterization...
An Assessment of Coupled Thermal-Hydrologic-Mechanical-Chemical Processes
A literature review was conducted to determine the state of knowledge available in the modeling of coupled thermal (T), hydrologic (H), mechanical (M), and chemical (C) processes relevant...
Geochemistry for High Level Waste: An International Comparison
This paper presents a brief summary of some of the recent and on going geochemical research related to the disposal of high level radioactive waste. For most categories of research (basic...
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...
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...
Comparison of Predicted Far-Field Temperatures for Discrete and Smeared Heat Sources
A fundamental concern in the design of the potential repository at Yucca Mountain, Nevada is the response of the host rock to the emplacement of heat-generating waste. The thermal perturbation...
The Analysis of Repository-Heat-Driven Hydrothermal Flow 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...
The Results of Near-Field Thermal and Mechanical Calculations of Thermal Loading Schemes
Two waste emplacement schemes, borehole and in-drift, are under evaluation as potential repository drift geometries for the Yucca Mountain Site Characterization Project. Calculations were...
Spent Fuel Assembly Source Term Sensitivity Parameters: SAND92-2113C TTC-1225
Containment of cask contents by a transport cask in a function of the cask body, one or more closure lids, and various bolting, hardware, and seals associated with the cavity closure and...
Influence of Deterministic Geologic Trends on Spatial Variability of Hydrologic Properties in Volcanic Tuff
Hydrologic properties have been measured on outcrop samples taken from a detailed, two-dimensional grid covering a 1.4 km outcrop exposure of the 10-m thick nonwelded-to-welded, shardy...
Rock Mass Mechanical Property Estimation Strategy for the Yucca Mountain Site Characterization Project
Rock mass mechanical properties are required in the design of repository drifts and ramps to assess the impact of thermal loads from the heat-generating wastes on excavation performance...
Single-Hole in Situ Thermal Probe for Hydrothermal Characterization at Yucca Mountain
The REKA thermal probe method, which uses a single borehole to measure in situ rock thermophysical properties and provides for efficient and low-cost site characterization, is analyzed...
