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...

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...

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...

Linkage Between Site Characterization Program and Performance and Design Data Needs
The basis for identifying site-specific data needs for the Yucca Mountain site was a thorough review and evaluation of the regulatory requirements for a geologic repository. The U.S. Nuclear...

The Coordination of System Representation and Operating Assumptions for System Studies in SIMS
Two projects at the Pacific Northwest Laboratory (PNL) have been devoted to development of the capability to provide descriptive details of the Federal Waste Management System (FWMS) and...

Fabrication and Closure Development of Nuclear Waste Containers for Storage at the Yucca Mountain, Nevada Repository
U.S. Congress and the President have determined that the Yucca Mountain site in Nevada is to be characterized to determine its suitability for construction of the first U.S. high-level...

Effects of Water Composition on the Dissolution Rate of UO2 Under Oxidizing Conditions
Dissolution rates were measured on crushed unirradiated UO2 fuel pellet samples under oxidizing conditions using a flow-through testing method. Water...
