A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...

Buried Structural Capacity of Insituform?
In July 1988, a test was conducted at Utah State University to determine the structural support that can be provided to a failing rigid pipe system through the use of the Insituform process....

Investigation & Rehabilitation of Seattle's Tolt Pipeline
Seattle Water Department's Tolt Pipeline brings water 24 miles from storage in the Cascade Mountains into city and suburban distribution systems. Twenty-three miles of this...

In-Situ Evaluation of 30-In. (762-mm) Diameter Prestressed Concrete Lined-Cylinder Pipeline
The results of an extensive investigation to evaluate the in-service condition and future serviceability of an existing lake water make-up pipeline are briefly described herein. The pipeline...

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...

Innovative Concept for Prestressed Pressure Pipe
A new design and manufacturing concept was developed by General Atomics for prestressed pressure pipe. With this new concept, patented in the U.S. and in the major industrialized nations,...

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...

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...

Cheyenne Stage II Water Delivery Pipeline and Shoshone Municipal Water Supply Pipeline
This paper deals with the design and construction aspects of two pipeline projects in Wyoming. Located in southeastern Wyoming, the Cheyenne Stage II Water Delivery Pipeline consists of...

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...

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...

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...

Field Experiment on Behavior of Continuous Water Main with a Miter Bend
A field experiment was conducted to investigate behaviors of a buried continuous steel water main with a 90-degree miter bend subjected to internal pressure and ground settlement. Deformations...

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...

Development of the Engineered Barriers for the Deep Geological Disposal of High-Level Radioactive Waste
Vitrified waste, overpack and buffer material are under research and development as engineered barriers in the deep geological disposal system of high-level radioactive waste. Static leach...

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...

Experience with Certifying Borated Stainless Steel as a Shipping Cask Basket Material
The original cask designs for a cask demonstration project featured fuel baskets constructed of borated stainless steel (bss) as a structural material. The project is intended to demonstrate...

Volatilization of Cesium and Ruthenium From High-Level Waste Glass
The contamination of the air above high-level waste glass by 134Cs, 137Cs and 106Ru...

Design Considerations for a Ceramic Fabric Radiator
The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment....
