As a follow-on to Sandia's 1991 preliminary total-system performance assessment of the Yuc1ca Mountain site, this paper presents results of some sensitivity analyses that were done using...

Rainfall and Net Infiltration Probabilities for Future Climate Conditions at Yucca Mountain
Performance assessment of repository integrity is a task rendered difficult because it requires predicting the future. This challenge has occupied many scientists who realize that the...

Numerical Methods for Fluid Flow in Unsaturated Heterogeneous Tuff
A numerical approach for modeling unsaturated flow is developed for heterogeneous simulations of fractured tuff generated using a geostatistical method. Cross correlations of hydrologic...

Assessment of Volcanic and Tectonic Hazards to High Level Radioactive Waste Repositories
Golder Associates Inc. (GAI) has developed a computer program (RIP) for performing probabilistic total system performance assessment and site characterization strategy evaluation which...

A Computer-Generated Film of Repository Operations
For the past fifteen years, the same types of questions concerning nuclear waste repository operations have kept coming up over and over again. What should be the average throughput for...

Modeling Gas and Brine Migration for Assessing Compliance of the WIPP
The U.S. Department of Energy (DOE) is developing the Waste Isolation Pilot Plant (WIPP) in southeastern New Mexico as a facility for the long-term disposal of defense-related transuranic...

A Note on Physical Modeling Approach for Assessment of Excavation Techniques
With the growing interest in utilizing underground space, the need for quantitative and qualitative assessment of excavation techniques to dictate the best choice for mining is now becoming...

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...

The Pursuit of International Science Literacy Through Energy Education: An Interdisciplinary Model for Curriculum Development
Over the past two decades science educators have employed the science, technology, and society (STS) framework for framing curriculum and for prescribing instruction. Ongoing world wide...

Modelling Gas Migration Experiments in Repository
In response to concerns over the possibility of hydrogen gas generation within an underground repository for high-level radioactive waste, and its implications for repository safety, a...

Heat and Vapor Transport Beneath an Impermeable Cap
Vadose-zone moisture transport near an impermeable barrier has been under study at a field site near Albuquerque, NM since 1990. Moisture content and temperature have been monitored in...

Role of Fracture Zones in Controlling Hydraulic Head and Groundwater Flow?Experience from Site Characterization Program in Finland
The preliminary site investigations for the final disposal of HLW produced by TVO have been carried out during 1987 - 1992 in five areas. All the areas consist of Precambrian crystalline...
