Synthesis of Studies for the Potential of Fault Rupture at the Proposed Surface Facilities, Yucca Mountain, Nevada
Published data for the Midway Valley area, the proposed site of the surface facilities of a high-level nuclear waste repository at Yucca Mountain, suggest that recognized regional faults...

Iodine Transport Through the Soil-Plant-Atmosphere Continuum
The environmental assessment of the geological disposal of Canadian nuclear fuel waste involves transport modelling of radionuclides through the biosphere. Iodine-129 is a major fission...

Educating American College Students on Issues Associated with the Isolation of Radioactive Wastes
A successful college-level course has been developed on issues associated with high-level and low-level radioactive waste. It emphasizes the background science. It has been taught to 150...

The Transportation Operations System: A Description
A system engineering approach is being applied to organize and develop relations among the people, hardware, and software of the Transportation Operations System (TOS), which will be a...

A Stratified Percolation Model for Saturated and Unsaturated Flow Through Natural Fractures
The geometry of the asperities of contact between the two surfaces of a fracture and of the adjacent void spaces determines fluid flow through a fracture and the mechanical deformation...

Drill-Back Studies Examine Fractured, Heated Rock
To investigate the effects of heating on the mineralogical, geochemical, and mechanical properties of rock by high-level radioactive waste, cores are being examined from holes penetrating...

Systems Engineering Applied to a Regulatory Program
The Nuclear Waste Policy Act directs the Nuclear Regulatory Commission to complete the licensing hearing process for the High-Level Radioactive Waste Geologic Repository within three years,...

A Demonstration of the Systems Integration Modeling System (SIMS) as a Decision-Support Tool
In April 1989, the Office of Civilian Radioactive Waste Management (OCRWM) Integration Branch completed major demonstration of the Systems Integration Modeling System (SIMS). That system...

An Investigation of the Mechanical and Hydrologic Behavior of Tuff Fractures Under Saturated Conditions
The mechanical and hydrologic behavior of natural-fractures in a partially welded tuff rock were investigated. Tuff cores, each containing part of the same natural fracture oriented subparallel...

Concepts in Prototype Testing for In Situ Geomechanical Investigations at Yucca Mountain
Geomechanical investigations comprise a significant portion of the site characterization program to be conducted at Yucca Mountain, the site of a proposed repository for nuclear waste....

Systems Integration During the Development of a Federal Waste Management System
Systems integration in the development of the Federal Waste Management System for spent nuclear fuel and high-level radioactive waste involves not only the activities traditional to development...

Important Factors in Developing a Nuclear Waste Management System
The nuclear waste management system provides unique challenges for a large and diverse segment of our society. For the politician there is the blending of national policy and the interests...

Assuring Data Quality for Use in Waste Management System Trade-Off Studies
This paper details the systems engineering approach developed to ensure the integrity of a large data library throughout its development and application. The paper assesses the benefits...

The Systems Integration Modeling System
The Systems Integration Modeling System (SIMS) is an analysis tool for the detailed evaluation of the structure and related performance of the Federal Waste Management System (FWMS) and...

A Systems Engineering Cost Analysis Capability for Use in Assessing Nuclear Waste Management System Cost Performance
The System Engineering Cost Analysis (SECA) capability has been developed by the System Integration Branch of the U.S. Department of Energy's Office of Civilian Radioactive...
