Hydrologic Characterization of Faults and Other Potentially Conductive Geologic Features in the Unsaturated Zone
The capability of characterizing near-vertical faults and other potentially highly conductive geologic features in the vicinity of a high-level-waste repository is of great importance...

Multi-Dimensional Modeling of Unsaturated Flow in the Vicinity of Exploratory Shafts and Fault Zones at Yucca Mountain, Nevada
Modeling studies were conducted to determine the potential effects of exploratory shafts on moisture distribution in the vicinity of an exploratory shaft facility, and the potential for...

Research for Final Disposal of Unreprocessed Spent Nuclear Fuel in Sweden
The second Swedish programme on research, development and demonstration in the nuclear radioactive waste management area was submitted by SKB to the Swedish National Board for Spent Nuclear...

Status of Site Investigations for Spent Fuel Repository in Finland
TVO's site programme aims at selection of a repository site for spent fuel by the end of 2000. A repository is planned to be constructed in the 2010's and commissioned...

Study of an Alternativefor Repository of Radioactive Waste?Taiwan Case
The accumlation of spent fuel and radioactive waste is forcing producers to look for repository systems in Taiwan. Tectonic setting, and geologic processes indicate that the Penghu Islands...

Applications of Fracture-Flow Modeling to Site Characterization
This paper describes practical applications of discrete-fracture approaches for design and analysis of groundwater flow about high-level radioactive waste repositories. The paper presents...

Site Specific Geologic Interpretations of Richton Salt Dome
There have been numerous investigations into the geological and hydrological aspects of the Richton Salt Dome area since its selection as a preferred site for a nuclear waste repository....

The Long-Term Climate Change Assessment Task of the Protective Barrier Development Program for Low-Level Waste Site Remediation at the Hanford Site
A study plan is being developed to guide a multiyear program to assess long-term climate change and optimize the design of protective barriers. A protective barrier alternative is being...

Calibration of High Frequency Pollen Sequences and Tree-Ring Records
Two radiocarbon dated paleoenvironmental records from southern Nevada are being examined with the possibility of correlating high-frequency pollen samples with nearby long-term tree-ring...

Environments of the Last 50,000 Years in the Vicinity of Yucca Mountain, Central-Southern Nevada
Located within the southern hydrographic Great Basin, the Nevada Test Site lies astride the transition between the Mojave Desert to the south and the Great Basin Desert to the north. Fossil...

Modeling Future Climates for Nuclear Waste Disposal
In order to ensure safe long term storage of nuclear waste it is necessary to consider possible consequences of future climate change. A program of long term climate scenario development...

Postclosure Safety Assessment of Radioactive Waste Disposal Systems: Current State of Understanding and International Consensus
Approximately ten years have passed since the first comprehensive safety assessments of radioactive waste disposal systems appeared. Through intensive efforts in practically all countries...

Overview of the U.S. Department of Energy's Pace-90 Geologic Repository Performance Assessment Exercise Activity
During 1989, the U.S. Department of Energy (DOE) initiated a determined effort to integrate and focus the performance-assessment activities required to support the preparation of an Environmental...

The Use of Performance Assessments in Yucca Mountain Repository Waste Package Design Activities
The Yucca Mountain Project is developing performance assessment approaches as part of the evaluations of the suitability of Yucca Mountain as a repository site. Lawrence Livermore National...

Prediction of Long-Term Behavior of Waste Package Materials in a Geologic Repository
An ASTM Standard Practice is under development as a national consensus standard on how to make and validate predictions of the long-term behavior of waste package materials in a deep geologic...

Analysis of Requirements for Data and Information for the Management of Spent Nuclear Fuel Designated for Disposal in a Mined Geologic Repository
Official documents and relevant published papers were reviewed to determine what information on spent fuel will be needed by the Department of Energy (DOE) in order for it to meet its...

Opportunities for the Nuclear Waste Negotiator
The Nuclear Waste Negotiator (the Negotiator) has the potential to have a significant positive impact on the United States High-level Radioactive Waste Management program perhaps more...

Social Issues and Challenges in the Disposal of Nuclear Waste
Equity and the perception of fairness are issues equal in importance to technical validity in the development of high-level waste management programs. With the passage of the Nuclear Waste...

Institutional Status, Challenges, and Plans Related to the MRS Program
This paper analyzes the role of institutional considerations in the Monitored Retrievable Storage (MRS) program. Among the issues that will be discussed are: the present focus of the MRS...

Characteristics of Potential Repository Wastes
The U.S. Department of Energy is responsible for the eventual disposal in a repository of spent fuels, high-level waste, and other radioactive wastes that may require long-term isolation....
