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...
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...
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...
The Last Twelve Months at Yucca Mountain
The U.S. Department of Energy (DOE) is evaluating Yucca Mountain in Nevada to determine if the site would be a safe location for a high-level radioactive waste repository. As mandated...
Being Responsive and Getting the Job Done Right
The United States Department of Energy (DOE) Yucca Mountain Site Characterization Project Office (YMSCPO) has been given the responsibility for characterization of the potential repository...
OCRWM'S Evolving Strategic Planning Process and the 1990 Plan
In 1990, the Secretary of Energy (Secretary Watkins) ordered that all 23 of the Department's major organizations adopt systems of strategic planning. This paper explains the...
Yucca Mountain Near Field Environment Considerations for Engineered Barrier System Design and Performance
Waste emplacement environment will be essentially dry for at least 300 years and will likely continue to be dry for more than 1000 years, both as a result of the unsaturated ambient conditions...
Effect of Ionizing Radiation on the Waste Package Environment
The radiolytic production of nitrogen oxides, nitrogen acids and ammonia are discussed in relation to the expected environment in a high-level waste repository that may be constructed...
Estimating Geochemical Behavior of Cocnretes to be Placed at Yucca Mountain
The interactions of J-13 water with cementitious materials were examined at 25?C using the geochemical code EQ3NR/EQ6. Results of the modeling suggested the following conclusions: (1)...
