Nondestructive Testing Using Borehole and Surface Seismic Techniques to Evaluate Rock Mass Damage Zones
A suite of seismic tests was performed at the U12g tunnel at the Nevada Test Site. The methods include borehole (crosshole and downhole) and surface (Rayleigh wave and refraction) tests....
Dry Drilling and Coring Development for Unsaturated Zone Studies
Two areas of major difficulty associated with characterization of any unsaturated zone are the conventional drilling and coring processes used to acquire the samples. These processes are...
Geologic Sample Handling and Logging at Apache Leap, Arizona
Early in 1990, the Yucca Mountain Project Office (Project Office; presently the Yucca Mountain Site Characterization Project Office) of the U.S. Department of Energy (DOE) completed two...
Boundary Integral Methods for Unsaturated Flow
A boundary integral equation method (BIEM) is described for numerical analysis of quasilinear steady unsaturated flow in homogeneous material. The applicability of the exponential model...
Theory of Matrix and Fracture Flow Regimes in Unsaturated, Fractured Porous Media
The flow behavior of a two-dimensional, unsaturated fracture-matrix system is characterized by a critical flux qf*...
Demonstration of a Repository Performance Assessment Capability at the U.S. Nuclear Regulatory Commission
In order to better review licensing submittals for a High-Level Waste Repository, the U.S. Nuclear Regulatory Commission staff has expanded and improved its capability to conduct performance...
Monitoring Compliance with Requirements During Site Characterization
The question of when a program of Regulatory Compliance should be applied and what it should be applied to, when the subject of compliance is a High Level Radioactive Waste Repository,...
Test and Evaluation of Natural Barriers at Yucca Mountain, Nevada: Management of the Site Characterization Program
The U.S. Department of Energy (DOE) is responsible for managing a characterization program for the Yucca Mountain site to collect data needed to determine if the site is suitable for recommendation...
Degradation Mode Surveys of High Performance Candidate Container Materials
Corrosion resistant materials are being considered for the metallic barrier of the Yucca Mountain Project's high-level radioactive waste disposal containers. Nickel-chromium-molybdenum...
Pore-Water Extraction from Unsaturated Tuffs Using One-Dimensional Compression
To support the study of the unsaturated-zone hydrochemistry at Yucca Mountain, Nevada, a one-dimensional compression system was developed and tested to extract unaltered and uncontaminated...
The Chemical Stockpile Intergovernmental Consultation Program: Lessons for High Level Waste Public Involvement
This paper assesses the appropriateness of the U.S. Army's Chemical Stockpile Disposal Program's (CSDP) Intergovernmental Consultation and Coordination Boards...
A Model for Effective Intergovernmental Planning
Effective intergovernmental planning processes are essential to the resolution of potential affects created by federal projects. In this paper, two successful planning efforts are described....
Opting for Cooperation?A Case Study in Siting a Low Level Radioactive Waste Management Facility
In 1986, the Canadian federal government called a halt to efforts by a crown corporation to site a low-level radioactive waste management facility when it became apparent that continuation...
Building Consensus in Developing Radioactive Waste Management Systems
To successfully develop radioactive waste management systems, national authorities must work to establish consensus on numerous complex issues among many affected and interested parties....
Preliminary Calculations of Release Rates from Spent Fuel in a Tuff Repository
Time-dependent release rates of Tc-99, I-129, Cs-135, and Np-237 have been calculated for wet-drip and moist-continuous release modes from the engineered barrier system of a potential...
Mechanical Excavator Performance in Yucca Mountain Tuffs
A research effort of four phases is in progress at the Colorado School of Mines. The overall program will evaluate the cutability of welded tuff and other lithologies likely to be excavated...
The Adoption of Mechanized Excavation Techniques for the Superconducting Super Collider
The Superconducting Super Collider (SSC) is the latest and largest in a line of high-energy physics accelerator projects. The five increasingly energetic accelerators which make up the...
Performance Assessment Calculational Exercises (PACE-90): Overview and Summary
PACE-90 was undertaken by the Yucca Mountain Site Characterization Project in order to develop expertise in computational capabilities and to aid in identification of critical elements...
Preliminary Performance Assessment of a Nevada Test Site Waste Disposal Facility
The performance of the Nevada Test Site Greater Confinement Disposal (GCD) site was assessed against the Environmental Protection Agency's (EPA) requirements for disposal...
