International Safeguards Relevant to Geologic Disposal of High-Level Wastes and Spent Fuels
Spent fuels from once-through fuel cycles placed in underground repositories have the potential to become attractive targets for diversion and/or theft because of their valuable material...
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...
Development of Transportation Operations Requirements: Operations Planning
Transport conditions at various utility sites vary dramatically in terms of characteristics at and near the site, requirements, administrative procedures, and other factors. Continuation...
Identification of Facility Constraints That Impact Transportation Operations
As Federal Waste Management Systems (FWMS) receiving facilities become available, the U.S. Department of Energy (DOE) intends to begin accepting spent nuclear fuel from U.S. utilities...
Selecting Preferred Routes for Highway Route Controlled Quantity Shipments of Radioactive Materials
The amount of spent nuclear fuel move in the U.S. in recent years has increased due to a number of government actions. One such action was the passage of the Nuclear Waste Policy Act which...
The SKI Regulatory Strategy and Performance Assessment Program in Relation to Final Disposal of Spent Nuclear Fuel and High Level Radioactive Waste
Important steps are planned to be made during the 1990s in the Swedish program for final disposal of spent nuclear fuel and high level radioactive wastes. Site selection will be done in...
Nagra Performance Assessment of Radioactive Waste Disposal in Crystalline and Sedimentaly Host Rocks
Nagra has evaluated disposal of vitrified HLW in both the crystalline basement of Northern Switzerland and in overlying argillaceous sedimentary formations. Although indicating that both...
Performance Assessment at the NRC: Current Issues and Recent Progress
Performance assessment plays a major role in the NRC's licensing program for the disposal of high-level radioactive waste. Planned and recent performance assessment activities...
Evaluation of Near-Field Thermal Environmental Conditions for a Spent Fuel Repository in Tuff
A repository heat transfer analysis is being performed by the Pacific Northwest Laboratory (PNL)a for the U.S. Department of Energy's...
?4C Release From Failed Spent Fuel Containers
Partially failed containers may provide a meaningful barrier to the release of gaseous radionuclides. A modeling approach is outlined and sample calculations are provided that show the...
Dry Spent Fuel Storage Compatibility at the Back End of the Fuel Cycle
The U.S. Nuclear Regulatory Commission (NRC) has publicly called for dry storage designs to be compatible with the back end of the fuel cycle, to achieve overall fuel cycle efficiency....
The Continuing Evolution of a Radioactive Material Transport System
The paper considers the evolution of BNFL's transportation system and those lessons learned and incorporated or being incorporated in the system as it continues to evolve....
BR-100 Spent Fuel Shipping Cask Development
Continued public acceptance of commercial nuclear power is contingent to a large degree on the U.S. Department of Energy (DOE) establishing an integrated waste management system for spent...
Certification Challenges in the Development of an Innovative High Payload Capacity Spent Fuel Transportation Cask
The design approach and certification strategy used in the development of an innovative transportation cask for legal weight truck shipments of spent nuclear fuel is presented. The proposed...
Operational Considerations in Specifying Legal Weight Vehicles for the Highway Transport of Spent Nuclear Fuel
This paper presents the results of a research project in which tractor manufacturers and carrier companies were interviewed to gather information on operational concerns in specifying...
Systems Models for Predicting Radioactive Waste
This paper illustrates how a model can be constructed to analyze the growth of accumulated spent Light-Water-Reactor fuel using a technique from systems theory which has proved to be capable...
Deposition of Airborne Particles from Fractured Spent Fuel or High-Level Waste
Preliminary equations are developed to predict the amount of deposition of airborne particles that may result from an accidental release in a hot cell. The fraction of these airborne particles...
Evaluation of the Canadian HLW Disposal Program?Performance Assessment Aspects
The inception and development of the Canadian HLW disposal program are described, showing its basis in the multi-barrier system concept and noting the mechanisms in place for its evaluation...
Acceptance of Spent Fuel of Varying Characteristics
This paper is a preliminary overview of a study with the primary objective of establishing a set of acceptance selection criteria and corresponding spent fuel characteristics to be incorporated...
Investigation of Burnup Credit Allowance in the Criticality Safety Evaluation of Spent Fuel Casks
The payloads of present generation spent fuel casks are constrained by a criticality design basis that assumes loading with unirradiated fuel. This presentation discusses work in progress...
