Comprehensive Leak Detection Survey and Benefit/Cost Analysis
Fort Carson, Colorado was the site of a comprehensive leak detection investigation of the potable water system with the express purpose of quantifying the benefits to be derived by a military...
Combined Load Testing of Prestressed Concrete Cylinder Pipe
A series of combined load tests were run on prestressed concrete cylinder pipe in order to evaluate a proposed new method of design for pipe made to AWWA Standard C301. These tests involved...
Evaluation of Combined Load Tests of Prestressed Concrete Cylinder Pipe
Combined load tests of prestressed concrete cylinder pipe, presented by Tremblay in the proceedings of this conference, are analyzed. Data gathered during the tests includes first visible...
Designing Vitrified Clay Pipe Systems with EASE
NCPI has developed a computerized trench load design program which provides a broad and complete spectrum of design options which will enable engineers and contractors to safely design...
A Look Back in Time to Verify Life Cycle Cost Analyses
The proper engineering design of any hydraulic structure requires consideration of different but interrelated fields of: 1) Planning, 2) Hydrology, 3) Hydraulics, 4) Structural, 5) Installation,...
Life Cycle Cost Analysis Discount Rates and Inflation
Life Cycle Cost Analysis techniques are useful for comparing alternatives that have differing cash flows over the expected life of a project. The selection of an appropriate discount rate...
Evaluation and Selection Methodology for Determination of a Preferred Pipeline Alignment
The San Diego County Water Authority (SDCWA) had need to construct a regional 108 to 72 inch (2.7 to 1.8 meter) diameter pipeline through San Diego County to increase water supply to its...
Approach to Developing a Ground-Motion Design Basis for Facilities Important to Safety at Yucca Mountain
The DOE has proposed a methodology for developing a ground-motion design basis for prospective facilities at Yucca Mountain that are important to safety. The methdology utilizes a quasi-deterministic...
Where's The Rabbit? Translating Science and Technology
Scientists and engineers must translate their 'Expertese' - their specialized languages - into words and ideas their different audiences can understand. The success...
Public Concerns of Nuclear Waste Issues in Taiwan
Opinions and comments from randomly selected 1837 general public and 454 professionals are compiled and analyzed to obtain their concerns on nuclear waste issues in Taiwan. Results indicate...
Managing Local Socioeconomic Impacts Through Project Management Policies Concerning Subsidized Transportation, Site Access, and On-Site Housing
The Department of Energy (DOE) has a legislative mandate to avoid, minimize and mitigate any adverse impacts to local communities resulting from activities at the Yucca Mountain Repository...
Social Realities in High-Level Radioactive Waste Management and Their Policy Implication
The management of high-level radioactive waste involves a number of enduring social realities that have posed major obstables to timely progress. These realities include: the deep-seated...
Current Social Systems Issues in the U.S. High Level Waste Management Program
Major changes in the U.S. high level waste management program since passage of the Nuclear Waste Policy Act of 1982 (NWPA) have weakened the social consensus about waste policy that existed...
Local Economic Impact Assessment of the Nevada Test Site: A Methodological Prelude to Socioeconomic Assessment of the Proposed Yucca Mountain High-Level Radioactive Waste Repository
The economic impact of the high level of nuclear repository can be approximated by studying the economic effects of the Nevada Test Site. Using the UNLV Nevada models, we estimated the...
