If concerns about global warming, acid rain and air pollution continue to mount, replacements for fossil fuels�for a century the dominant power source in the U.S.�will be necessary to...
Management of High-Level Wastes in the Republic of China
Because of the importance of nuclear energy in the Republic of China, the management of associated radwastes, especially the high-level wastes (HLW), is indispensable for today's...
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...
