Houston Moves Forward Again
The National Transportation Plan, as released by Transportation Secretary Samuel Skinner, advocates the construction of toll roads and calls on local governments to devise and finance...
Trouble on the Waterways?
Crumbling highways and bridges can cripple the U.S. economy. A lesser known transportation problem is the condition of our inland waterway system. Waterways are a cost-efficient, environmentally-sound...
Beneficial Use of Coal Ash as a Structural Fill
For decades, electric utility companies have and will continue to dispose of their coal ash in various waste disposal sites. In the state of Pennsylvania, the Beneficial Use of Coal Ash...
Vine Street Reborn
Following decades of controversy and a four-year construction effort that threatened to drive both engineers and local motorists crazy, Philadelphia's Vine Street reopened...
Dallas' Flood Caverns
Dallas' North Central Expressway floods during heavy rains, but the dense development that helps create excessive runoff also precludes large detention ponds. The high-quality,...
OCRWM Transportation Technical Activities for 1998
The Office of Civilian Radioactive Waste Management is preparing for the transport of spend fuel by 1998 from commercial reactors to a monitored retrievable storage facility. The preparations...
Approach for Implementing Burnup Credit in High-Capacity Truck Casks
General Atomics (GA) will be submitting an application for certification to the U.S. Nuclear Regulatory Commission (NRC) for the GA-4 and GA-9 Casks in 1992. To maintain a capacity of...
Effects of Heterogeneity on Actinide Diffusion Rates in Tuffaceous Rock
The pore structure and mineralogy of Topopah Spring Tuff are heterogeneous on scales less than one cm. This heterogeneity creates spatial variation in transport rates for aqueous actinide...
How Much Must the Geologic Barrier Contribute to Safe HLW Disposal?
As a prerequisite of a potential repository site, it is important to assess the role of each system component in providing safety and, in particular, to establish the specific geological...
Flow and Transport Around a Noncontinuous Horizontal Layer at Yucca Mountain
Computer simulations were used to examine the effect of a noncontinuous horizontal layer on the flow field and contaminant transport of a simplified conceptual model. The domain consisted...
Development of Preliminary Nevada Transportation Accident Characteristics
The U.S. Department of Energy (DOE), Yucca Mountain Site Characterization Project Office (YMSCPO) has been given the responsibility for characterization of the potential repository site...
Unintentional Stoppages of Trucks Hauling High-Level Nuclear Waste in Nevada
Any unintentional stoppage of trucks hauling high-level nuclear waste in Nevada could intensify public concerns about the negative impacts of the Yucca Mountain project. This paper provides...
Transportation of Radioactive Materials Routing Analysis: The Nevada Experience
In 1987, the Nevada State Legislature passed a Bill requiring the Nevada Department of Transportation to develop and enforce a plan for highway routing of highway route controlled quantity...
Development of Rail Access to the Proposed Repository Site at Yucca Mountain
In accordance with the Nuclear Waste Policy Amendments Act of 1987, Yucca Mountain was designated as the initial site to be investigated as a potential repository for the disposal of high-level...
An Approach to Evaluate the Sufficiency of Highway Bridges for Nuclear Spent Fuel Transportation
The transportation of radioactive spent fuel can have a significant impact on bridge structures located on designated routes. Due to the critical nature of the cargo and because of the...
Transportation Access to Yucca Mountain: Critical Issues
Transportation planning for a repository at Yucca Mountain is complicated because of uncertainty about the modes and numbers of nuclear waste shipments and because of uncertainty about...
The Oregon Experiment: Public Information and Involvement
Oregon is neighbor to the Hanford Nuclear Site that now has the nation's largest store of radioactive waste. Oregon supports Hanford cleanup, which will require waste transport...
Barometric Pumping of Contaminated Gases Through Fractured Permeable Media
Contaminated gases may be transported vertically through a fractured permeable medium by the breathing process which is associated with cyclical changes in the barometric pressure. A review...
Advances in the Study of Far-Field Phenomena Affecting Repository Performance
Studies of far-field phenomena affecting repository performance have focussed on the role of fractures and other heterogeneities in the potential transport of radioactive solutes from...
Process and Criteria for Valuation of the Ground-Water Flow Models in the OECD/NEA International Stripa Project
In 1986, the Site Characterization and Validation (SCV) Program was initiated as part of Phase III of the OECD/NEA International Stripa Project. The principal intent of the SCV Program...
