This paper assesses the potential transport of high-capacity Initiative I highway casks under development by the Office of Civilian Radioactive Waste Management (OCRWM) as permitted marginal...
Containment Barrier System Performance Assessment Modeling
A mathematical model to predict the cumulative failure distribution for the containment barrier system (CBS) employed in a deep geologic disposal facility is presented as a function of...
The Analysis of Repository-Heat-Driven Hydrothermal Flow at Yucca Mountain
To safely and permanently store high-level nuclear waste, the potential Yucca Mountain repository site must mitigate the release and transport of radionuclides for tens of thousands of...
Spent Fuel Assembly Source Term Sensitivity Parameters: SAND92-2113C TTC-1225
Containment of cask contents by a transport cask in a function of the cask body, one or more closure lids, and various bolting, hardware, and seals associated with the cavity closure and...
Reliability Modeling of an Engineered Barrier System
The Weibull distribution is widely used in reliability literature as a distribution of time to failure, as it allows for both increasing failure rate (IFR) and decreasing failure rate...
Micromechanics of Deformation in Topopah Spring Tuff, Yucca Mountain, Nevada
Samples of Topopah Spring tuff from Yucca Mountain, Nevada have been tested and analyzed. Laboratory tests conducted include standard uniaxial and triaxial compression tests, and special...
Alternatives Analysis Using Two-Dimensional Modeling for the Owensboro Bridge and Approaches
The Federal Highway Administration plans to design and construct a new bridge over the Ohio River near Owensboro Kentucky. A hydraulic model with two-dimensional capabilities was utilized....

Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...
Finite Element Representation of Approach Slabs
Approaches to bridges are designed to provide a smooth and safe transition from the highway pavement to the bridge deck and back to the highway pavement. Generally this transition area,...
Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...
A New Approach for Road Network and Bridge Planning
Road networks usually include a large number of bridges and tunnels. The locations of these bridges and tunnels are decided by the road planner during the design of the road alignment...
Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...
