Dry Spent Fuel Storage in the 1990's
In the United States, for the decade of the 1990's, at-reactor-site dry spent fuel storage has become the predominant option outside of reactor spent fuel pools. This development...
A Proposed Regulatory Guide Basis for Spent Fuel Decay Heat
A proposed revision to Regulatory Guide 3.54, 'Spent Fuel Heat Generation in an Independent Spent Fuel Storage Installation' has been developed for the U.S. Nuclear...
Evaluation of Storage/Transportation Options to Support Criteria Development for the Phase I MRS
The Department of Energy's (DOE) Office of Civilian Waste Management (OCRWM) plans to develop an interim storage facility to enable acceptance of spent fuel in 1998. It is...
Interim Storage of Solidified High Level Wastes
Indian approach to the problem of interim storage of vitrified high level wastes, indicating design philosophy adopted for air cooled vault at Tarapur has been described. Important design...
Interim Waste Storage for the Integral Fast Reactor Fuel Cycle Demonstration
An interim storage system design and operating strategy were developed for implementation in the Integral Fast Reactor Fuel Cycle Demonstration. Waste characteristics and thermal power...
Uncertainty Analysis of Preclosure Accident Doses for the Yucca Mountain Repository
This study presents a generic methodology that can be used to evaluate the uncertainty in the calculated accidental offsite doses at the Yucca Mountain repository during the preclosure...
A Decision Support System for Performance-Based Site Characterization
The complex and dynamic requirements of site characterization present a major management challenge. ParaTrac, a regulatory and technical information system, is described as a valuable...
A High-Level Waste Repository Performance Assessment Methodology
This project was sponsored by the Electric Power Research Institute to examine methods that coordinate information from various disciplines to present an integrated perspective on the...
Site-Generic Approach for Performance Assessment of HLW Disposal System in Japan
This paper presents an overview of the preliminary performance analyses and description of R&D activities designed based upon the results of the analyses, which are to be incorporated...
Total-System Analyzer for Performance Assessment of Yucca Mountain
The Total-System Analyzer is a modular computer program for probabilistic total-system performance calculations. The code employs stratified random sampling from model parameter distribution...
Reservation Rebirth?
Slightly under one million American Indians live on reservations�legally sovereign nations that occupy a total land area the size of New England. Unbound by county and state environmental...
Radioactive Waste: Finding a Safe Place
The Nuclear Waste Policy Act of 1981 and its amendments mandate that the U.S. Department of Energy find a repository for the nation's high-level radioactive wastes, characterize...
The Long Climb to Remediation
During World War II, the Rocky Mountain Arsenal in Colorado served as an Army manufacturing center for the production, then destruction, of mustard gas, napalm, cluster bomb mixtures,...
Closing Hazardous Landfills
Designing and constructing covers for uncontrolled hazardous-waste landfills can pose some special problems�such as differential settlements as great as 50% of landfill thickness. Under...
Fear of Trying
Conventional methods for cleaning up hazardous-waste sites are expensive, subject to increasing restrictions, and don't work that well for certain types of waste. Innovative...
Building a Geographic Information System (GIS) for Siting New York City Sludge Management Facilities
Siting studies for waste facilities usually focus on a particular geographic region, or a defined study area, and are restricted to a specific technology. However, the siting of land-based...
Management and Statistical Analysis of Groundwater Monitoring Data at Solid Waste Landfills
Solid waste landfills in Ohio and Michigan, as in many states, are required to have monitoring wells. Groundwater samples from these wells are analyzed to determine if leachate from the...
