Analysis of Soil-Stress Cell Interaction
Static loading experiments conducted on a soil stress cell embedded in a sand are presented. Stress cell performance was evaluated by comparing the indicated stress against the expected...
Drifted Snow on Roofs
Drift snow loads on multilevel roofs account for about 75 percent of all snow load related roof collapses. A case history of snow drifts provides the foundation for a discussion of the...
Earth Walls: Making the Right Choice
Earth walls are retaining walls where the ground assumes a load-bearing role. These walls either support compacted earth (embankment-type reinforced compacted earth walls such as Doublewal...
Valuing Residual Emissions in Electricity Planning
Incorporating the valuation of residual emissions into calculations of social cost permits comparisons among alternative sources of electricity generation inclusive of environmental impacts....
Hydrogen?The Clean Fuel of Tomorrow is Available Today
This paper examines the role of fossil fuels and advocates a proactive energy policy to stimulate the use of domestically produced 'clean' energy carriers (fuels),...
Public Policy Issues for Sustainable Commerce
Sustainable commerce is the process of providing the material needs of a society while using natural resources no faster than they are being generated and generating wastes no faster than...
Sustainable Energy Systems: A New Paradigm for New Energy Technologies
The fundamental links between energy production/use and the environment are becoming increasingly apparent. The major environmental challenges of global climate change, acid precipitation,...
Improved Corrosion Protection for Flue Gas Systems Utilizing a Dual Liner Concept
A unique system of corrosion resistant materials has shown excellent performance and durability in flue gas systems for fossil plants, cogeneration plants, waste incinerators and waste-to-energy...
The Changing Legal Structure of Non-Utility Generation in the 1990's
Before actual construction of a small power production or cogeneration facility commences, numerous economic, technical and legal factors have been considered during the planning process....
Nuclear Plant License Renewal: Benefits, Feasibility, and Process
The future of power plants in the U.S. is of growing concern. The need for competitively priced and economically safe plants is a must. The reluctance of the utility industry to produce...
Innovative Aspects of the DQE/GPU Project
The DQE-GPU joint project is an endeavor at supplying electricity to its customers in an economically competative way. The project cosists of using existing power stations in the Three...
The Human Factor in Failures
Human shortcomings cause three-quarters of project failures. A study of 500 case histories led to this assumption. One such failure at the Walter Bouldin dam in Alabama, is described in...
Jailhouse Design
According to statistics from national corrections groups, the inmate population in the U.S. has reached 1 million and could double by 1995. With the constant need for more beds, engineers...
Approximate Preliminary Methods for Design of Lateral Load Resisting Systems in High Rise Buildings
A new group of optimization programs uses the speed and power of modern computers to eliminate the need for guessing preliminary sizes. Starting with any arbitrary sizes and a fixed geometry,...
High-Capacity, High-Strength Trailer Designs for the GA-4/GA-9 Casks
General Atomics (GA) is developing final designs for two dedicated legal-weight trailers to transport the GA-4 and GA-9 Spent-Fuel Casks. The basic designs for these high-capacity, high-strength...
Multiple Event Considerations for Postclosure Seismic Hazard Evaluations at Yucca Mountain, Nevada
Postclosure waste canister design requirements suggest the values used for seismic design have less than a 10% chance of being exceeded in a 1,000 year postclosure period. Considerably...
High-Level Waste Disposal Regulations: Time for a Change?
Major developments since EPA's high-level radioactive waste disposal regulations were promulgated challenge the validity of some of the assumptions underlying these regulations....
Human Intrusion Scenarios in Nuclear Waste Repository Evaluations
When promulgated, the Environmental Protection Agency (EPA) High Level and Transuranic Waste Standard (40 CFR 191) is expected to require consideration of human intrusion into a nuclear...
Concept Development of Small Cask to Large Cask Transfer Systems
Studies for EPRI have been performed by two contractors to develop conceptual designs for small cask to large cask transfers of spent fuel. From the work, two dry transfer concepts and...
Rethinking the Economic factors of Centralized Spent Fuel Storage
The economics of centralizing the storage of spent fuel at a single site, as opposed to continued storage at over 100 reactor sites, has been the subject of several recent analyses. Most...
