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...

A Computerized Completion
The original designers of the 1.6 million sq ft Fillmore Center in San Francisco (its largest mixed-use development project in 20 years) had specified a large amount of steel reinforcement...
Building Beneath Boston
Up/down construction is a method in which a project's substructure and superstructure are simultaneously built. The substructure's wall, column and foundation...
Fixing Foundations
Conventional underpinning or pilings are still the most common construction methods used to strengthen foundations, but new grouting techniques are giving engineers some fresh alternatives....
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,...
Development of the ASME/NUPACK Code
A Committee has been active for 10 years to develop Code rules for the design, construction and in-service requirements of containment systems for nuclear spent fuel and high level radioactive...
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...
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...
Design Considerations for the Yucca Mountain Project Site Characterization
The Site Characterization Facilities (SCF) to be located in volcanic tuff at Yucca Mountain is a challenge to manage, design, and construct. This challenge is a result of a number of factors....
Application of QA Grading to Yucca Mountain Site Characterization Project Items and Activities
Grading is the act of selecting the quality assurance (QA) measures necessary to develop and maintain confidence in the quality of an item or activity. The list of QA measures from which...
High-Level Waste Disposal Regulations: Time for a Change?
Major developments since EPA's high-level radioactive waste disposal regulations were promulgated challenge the validity of some of the assumptions underlying these regulations....
Gaseous Release of Carbon-14: Why the High Level Waste Regulations Should be Changed
The high-level nuclear waste regulations pertaining to gaseous release of carbon-14 from a repository should be changed to allow greater release, for several reasons. Some of them are...
The Development Process for Unique Underground Equipment for Waste Handling
The Department of Energy (DOE) is currently planning to site, construct, and operate a geologic repository at Yucca Mountain, Nevada, for the disposal of high-level nuclear waste (HLW)....
Removal of Dissolved and Suspended Radionuclides from HWVP Liquid Wastes
It was determined during Preliminary Design of the Hanford Waste Vitrification Plant that certain intermediate process liquid waste streams should be decontaminated in a way that would...
