Effect of Minor Actinide Removal From Fission Products Before Vitrification on the Radiological Impact of a High Level Waste Deep Repository
The topic of this work is to assess the effect of minor actinide (Cm, Am, Np) removal from fission products before vitrification on the radiological impact of a vitrified waste geological...

The Source Term for HLW Disposal in the European Communities' R&D Programme
During the last five years, the EC's research programme on radioactive waste has focused much of its investigation in the field of HLW management on the source term for geologic...

Requirements for Controlling a Repository's Releases of Carbon-14 Dioxide; The High Costs and Negligible Benefits
A repository excavated within the unsaturated zone may release carbon(C)-14 dioxide in amounts that exceed limits imposed by the Environmental Protection Agency (EPA) and the Nuclear Regulatory...

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...

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...

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...

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...

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...

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....

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...

A Literature-Based Preliminary Characterization of Risks in the Nuclear Waste Management System
