Whitfield Reservoir Inlet Outlet Pipeline
Alameda County Water District reports on the planning, design and construction of a 48-inch water main installed under modern urban circumstances. The location of the pipe and the construction...
Pipeline Design and Construction Using High Density Polyethylene (HDPE) Pipe
All pipelines and pipe materials must be designed and constructed to address the limitations of the pipe and fittings in order to insure acceptable performance of the line. Conventional...
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...
Analysis of Alternative Pipe Materials for a Major Public Water Agency
A major southwestern public water agency has historically specified the exclusive use of prestressed concrete cylinder pipe (PCCP) for large diameter water transmission mains. Due to the...
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...
Twin Pipeline Crossing of the Fraser River
A new creek water supply was developed for the communities of Mission and Matsqui, British Columbia, Canada, in the early eighties. Over 60 kilometres of 450 mm to 900 mm diameter ductile...
Relining of Jordan Aqueduct, Reach 3
As pipelines approach their life expectancy, they may need to be replaced. Or in some instances, replacement is needed much sooner due to defective pipe. Normal replacement operations...
Less Bang for the Buck
Blasting rock is practical on job sites with ample space, but on construction sites in urbans or developed settings, contractors are shying away from blasting for several reasons. Noise...
Shop Drawings: In Need of Respect
Engineer Robert L. Boehmig voices his concerns regarding the preparation of structural shop drawings. He gives his view of the shop drawing's role in construction projects,...
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...
A Proposed Methodology for Validating Performance Assessment Models for the DOE Office of Civilian Radioactive Waste Management Program
The Department of Energy (DOE) has developed a draft methodology for validating performance assessment models that will be used in the licensing of high-level waste repository systems....
Status of Integrated Performance Assessment of the Waste Packages and Engineered Barrier System
Performance assessment of the engineered barrier system for a nuclear waste repository combines information from relevant disciplines and predicts the net long-term performance of the...
TN28V High Capacity Cask for the Transport and Storage of Vitrified Wastes
When the option of reprocessing has been selected, closing of the fuel cycle implies the return shipment of reprocessing wastes back to the country of origin of the spent fuel, in particular...
A Numerical Study of Some Effects of Nuclear Fuel Waste Vault Construction and Closure on Evolution of Groundwater Flow Paths in the Geosphere
We have performed a series of three dimensional finite-element simulations on the sensitivity of the groundwater flow paths and travel times in a conceptual hydrogeological model with...
Simulation Modeling of Subsurface Development
This paper discusses the use of simulation modeling in analyzing subsurface development activities and estimating associated costs at the Yucca Mountain candidate repository site. Described...
Trends in Waste Management Program Costs: An Evolution of Estimating Methods and Results
The purpose of this paper is to present a summary of how the program cost projections contained in the five TSLCC analyses performed to-date and the estimating methods used to make these...
Materials Selection Issues for Structural Components of Transportation Casks
Sandia National Laboratories (SNL) is evaluating the use of alternate materials (i.e. other than stainless steel) as structural components in nuclear spent fuel transportation casks. This...
Programmatic Challenges and the Value of Testing on the West Valley Demonstration Project's Vitrification Facility Design
The primary objective of the West Valley Demonstration Project (WVDP) is the solidification of approximately 2.1 million liters (560 thousand gallons) of high-level waste (HLW) which resulted...
An Overview of the Vitrification of Defense High-Level Waste at the Hanford Site
Nearly 63 percent of the nation's high-level nuclear waste has accumulated at the U.S. Department of Energy's (DOE) Hanford Site in Washington State. This accumulation...
