Containment Model ? Test Program and Results
Sandia National Laboratories (Sandia) completed the testing of a 1:6-scale containment building for a Light Water Reactor (LWR) in July 1987. The containment building was made of reinforced...
Development of a Test Validated Methodology for Predicting Concrete Containment Leakage
In the past several years, considerable research effort has been devoted by the Electric Power Research Institute and the U.S. Nuclear Regulatory Commission to the behavior of reactor...
Vibration Control Damper Using Sloshing of Water
The objective of this study is to develop a method of reducing wind-induced vibration of long-period structures utilizing sloshing of water in tanks added to the upper part of the structures....
Coal Gas Legacy
The remains of a former coal gasiication plant were uncovered during redevelopment of a site for the new City Hall in Waterloo, Ont. The coal tar waste was a dense, immiscible tarry fluid...
The Challenge of Yucca Mountain
Yucca Mountain is the most likely site for the nation's high level nuclear wastes. Congress chose the site out of three candidates for further study before designating it...
Accelerating Electrons
At a wastewater treatment plant in Miami, five scientists have pointed a 1.5 million v `e-beam' at pathogens and hazardous chemicals. It's the only full-scale...
Seismic Isolation of Storage Tanks
There has been a significant amount of research activity over the past decade on the seismic design of storage tanks. The seismic design issues and limit states are quite complex due to...
Membranes in Water Treatment
Membrane technology, using reverse osmosis to treat drinking water, is a promising alternative to conventional treatment. The method is now being used for desalination in a growing number...
Buying Tomorrow's Water
Cities are finding that selling future access rights to sewer and water treatment plants can get them needed expansion capital. Although the access rights system is similar to development...
High Hopes for Cattails
As other areas of wastewater treatment go high tech, man-made wetlands are treating wastewater from small towns and coal mines. Plants are grown in about 1 ft of water. Suspended solids...
Site Characterization of Yorktown Formation for New Accelerator
The design of a new 1700-m long continuous-wave electron beam accelerator facility (CEBAF) in Newport News, Virginia demanded an extensive geotechnical exploration program be conducted...
Screw Plate Test for Drained and Undrained Soil Parameters
This paper describes a screw plate test device developed with a capability to measure the generation and dissipation of excess pore water pressure during testing in cohesive soils. The...
A Use of Geostatistics to Predict the Occurrence of Collapsing Soils
Collapse susceptible soils are those that are stable under load while they are dry, but undergo large decreases in volume virtually instantaneously, when they become wetted to near saturation...
Backbarrier Beaches on a Developed Shoreline
The purpose of this paper is to identify the nature and magnitude of alterations to backbarrier environments on Island Beach Spit, NJ. This location was selected because it has different...
Barrier Beach Water Table Management
The solution to the water table elevation within a barrier beach, subject to the assumptions of a homogeneous and isotropic phreatic aquifer, is an ellipse with its long axis oriented...
Historical Shoreline Changes: A Comparison of Mean High Water and Vegetation Line Movement
A cooperative study produced historic mean high water shoreline change maps for the State of South Carolina. These maps have been used to calculate erosion rates for the entire developed...
Ponds and Lagoons of Gulf Islands National Seashore
A physical and natural resource survey was conducted of the ponds and lagoons on Horn and Petit Bois Islands, Gulf Islands National Seashore, Mississippi. Petit Bois Island contains 17...
Erosion and Washover in Coastal Louisiana
In 1985 three hurricanes affected the barrier coastline (Caminada-Moreau Headland) of Louisiana. These produced severe coastal erosion and rapid washover extension. Using the 1979 U.S.G.S....
The South Carolina Coast II. Development and Beach Management
The variety of development and conservation areas is superimposed on a wide range of erosion and accretion histories. Lack of construction setbacks has contributed to the general but probably...
A Review of the South Carolina Method for Establishing Coastal Setback Lines
The location of the setback line will depend to a large extent on the nature of the shoreline. Those areas adjacent to an unstabilized tidal inlet and affected by coastal processes at...
