Design of Ductile Iron Pipe on Supports
Design procedures for ductile iron pipe in normal underground service have been well established. The standard design considers hoop stresses in the pipe wall due to internal hydrostatic...

Performance of Pipe Spillways for Dams
The Soil Conservation Service has used several different kinds of pipe products for spillway conduits of dams. Materials with a shorter estimated life are used for smaller low hazard dams...

Failure of Prestressed Concrete Embedded Cylinder Pipe
In 1964, the Ontario Provincial Government undertook to supply water to the City of London (current population 300,000). The supply source was from Lake Huron near Grand Bend, Ontario...

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...

Pipeline Explodes, Two Dead, 31 Injured, 11 Homes Destroyed
A high pressure pipeline in a suburb of San Bernardino, California exploded in a deadly fireball on May 25, 1989. Damaged as a result of a train wreck several weeks earlier, or by the...

Corrosion Protection of Cast Iron and Ductile Iron Pipe, San Diego, California
This paper addresses the use of a loose unbonded plastic covering polyethylene encasement for protection of cast and ductile iron pipe in an extremely corrosive soil. The case study in...

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,...

Landfill Gas Pipe Selection and Installation
Sanitary landfills present a unique array of pipe selection and installation criteria when designing landfill gas (LFG) control and recovery systems. Factors that must be considered include...

Structural Safety and Reliability
This proceedings of the 5th International Conference on Structural Safety and Reliability (ICOSSAR '89) held on August 7-11, 1989 in San Francisco, California contains almost...

Museum Showcases the Future
On May 4 in Philadelphia, the Franklin Institute's new wing, called the Futures Center, will open to the public. When the institute's neoclassic main buiding...

The Next Earthquake
The California's October 1989 Loma Prieta earthquake confirmed must of the current research and practice about structural engineering and seismic events. It also highlighted...

Kinematic Models of Extensional Structures: Seismic Implications
Kinematic models can relate faults of different types and different positions within a single dynamic system and thereby offer the potential to explain the disparate seismic activity characteristic...

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...

Estimating Earthquake Sizes in the Basin and Range Province, Western North America: Perspectives Gained from Historical Earthquakes
Thirty eight historical earthquake from the Basin and Range province were used to examine three aspects of earthquake size and behavior: 1) the maximum background earthquake, 2) earthquake...

A Preliminary Model for Carbon-14 Transport in a Clay Buffer
A model has been developed to assess the effect of calcite dissolution and precipitation reactions on the transport of 14C through a saturated, calcite-containing...

Natural Radionuclides in Groundwater From J-13 Well at the Nevada Test Site
The concentrations of U-238 and Th-232 chain members are extremely low in J-13 water, suggesting that their concentrations in groundwaters are largely governed by sorption/desorption processes....

One-Dimensional Radionuclide Transport Under Time-Varying Conditions
New analytical and numerical solutions are presented for one-dimensional radionuclide transport under time-varying fluid-flow conditions including radioactive decay. The analytical solution...

Simulation of Radionuclide Retardation at Yucca Mountain Using a Stochastic Mineralogical/Geochemical Model
This paper presents preliminary transport calculations for radionuclide movement at Yucca Mountain using preliminary data for retardation parameter distributions based on mineral distributions....

Radioactive Materials Packaging Standards and Regulations?Making Sense of it All
Numerous regulations and standards, both national and international, apply to the packaging and transportation of radioactive material. These are legal and technical prerequisites to practically...
