Containment Capacity and Failure Modes Beyond Design Basis Conditions
Analytical and experimental studies have shown that containments can at least sustain two to three times design pressures. Under the severe accident overpressure loading, experimental...
Fly Ash Grouts for Subsidence Control
A laboratory investigation was undertaken to examine procedures for evaluating candidate grouts and to develop quality grouts for use in abandoned mines. The objective of this grout application...
Properties and Environmental Impact of Stabilized Fly Ash
This paper summarizes the results of two research studies aimed at evaluating the properties and possible environmental effects of bituminous and lignite coal based fly ashes stabilized...
Stabilized Fly Ash Cover for a Municipal Waste Landfill
The study reported herein and several recently related projects have been aimed at reducing the hydraulic conductivity of fly ash and physiochemically fixing any potential leachable metals....
Leachate Flow from an Experimental Fly Ash Landfill
Combustion of coal in large-scale utility boilers produces an ash by-product which is often stored in open landfills. An experimental fly ash landfill was constructed by Pennsylvania Power...
Dam, Spillway and Hydropower Rehabilitation
Many older dams are in need of rehabilitation as a result of aging, deterioration, and more stringent safety standards. Current deficiencies include deterioration of original construction...
Fly Ash in Roller Compacted Concrete Pavement
This paper presents the state of practice on the use of fly ash in roller compacted concrete (RCC) pavements. Placed using asphalt pavers and compacted using asphalt rollers, RCC pavement...
Superplasticized High-Volume Fly Ash Structural Concrete
This research was carried out to develop structural grade concrete containing high-volumes of ASTM Class C fly ash. A Portland cement concrete, proportioned to have 28-day compressive...
Low-Rise Shear Wall Failure Modes
A summary of the data that are available concerning the structural response of low-rise shear walls is presented. These data will be used to address two failure modes associated with shear...
Failure Modes of Flat Bottom Vertical Storage Tanks
Flat bottom vertical storage tanks are important components in essential nuclear power plant safety systems. Data on the seismic capacity and failure modes of such tanks have been identified,...
Advanced Composites Materials in Civil Engineering Structures
This proceedings of the Specialty Conference on Advanced Composites Materials in Civil Engineering held in Las Vegas on January 31?February 1, 1991 contains 40 papers from ten technical...
Making the New Look Old
Between March 1990 and January 1991, Annapolis buried overhead utilities and reconstructed the roadway around the historic State House, built in 1769. The paving stones, colonial-appearing...
Jailhouse Design
According to statistics from national corrections groups, the inmate population in the U.S. has reached 1 million and could double by 1995. With the constant need for more beds, engineers...
The Boundary Element Method in Engineering Practice
The boundary element method (BEM) provides an excellent basis for the development of integrated design and analysis systems. The technique possesses the advantages of simple model generation,...
Multiple Event Considerations for Postclosure Seismic Hazard Evaluations at Yucca Mountain, Nevada
Postclosure waste canister design requirements suggest the values used for seismic design have less than a 10% chance of being exceeded in a 1,000 year postclosure period. Considerably...
Weapons Test Seismic Investigations at Yucca Mountain
Yucca Mountain, located on and adjacent to the Nevada Test Site, is being characterized as part of an ongoing effort to identify a potential high-level nuclear waste repository. This site...
Spent Fuel Waste Form Characteristics: Grain and Fragment Size Statistical Dependence for Dissolution Response
The Yucca Mountain Project of the U.S. Department of Energy is investigating the suitability of the unsaturated zone at Yucca Mountain, NV, for a high-level nuclear waste repository. All...
Migration Experiments at the Grimsel Test Site, Switzerland
The Grimsel Migration Experiment is a multidisciplinary study aimed at testing models of solute transport in fractured media, determining the degree to which laboratory results could be...
Interpretative Modelling of Studies of Sorption of Radionuclides onto Geological Materials
An integrated modelling and experimental approach related to the quantification of the sorption of radionuclides onto geological materials is described. The primary role of the experimental...
Assessment of Fracture-Sampling Techniques for Laboratory Tests on Core
As part of the site characterization work to be done at Yucca Mountain in Nye County, Nevada, a candidate site for the first mined-geologic repository for high-level nuclear waste, laboratory...
