Dynamic Compaction of Nuclear Waste
When ponding, caused by settlement of the original soil cover over low-level nuclear waste buried at the Department of Energy's Savannah River Nuclear Plant near Aiken, S.C.,...

The Environment is Good Business in France
The environmental movement is an important political concern in Europe with the Green party gaining ground in several nations. The European Economic Community is developing environmental...

Value Engineering at a Superfund Site
The Helen Kramer Landfill ranked fourth on the EPA's National Priorities List and the estimated cost of clean up was about $39 million. By value engineering selected parts...

Coal-Gas Conundrum
Manufactured gas from coal brought streetlights and clean cooking fuel to the late Victorian era, but a hundred years later their legacy isn't quite so beneficial. Investigators...

Densification/Creep Behavior of Experimental Glass-Ceramic Waste Forms for Immobilization of High-Level Calcined Waste at the Idaho Chemical Processing Plant
A mixture of simulated high-level calcined waste (HLW) and Frit additives was hot isostatically pressed (HIPed) to a dense glass-ceramic waste form. A densification mapping software was...

Geoelectrical Tomography: Model Studies Related to Nuclear Waste Site Characterization
Borehole geoelectrical measurements offer a promising means for detecting and delineating resistivity anomalies in candidate geological formations being considered for underground storage...

Effect of Water on the Consolidation of Crushed Rock Salt
The consolidation behavior of crushed rock salt, as the backfill in the under-ground disposal of nuclear waste, will be important in controlling room closure rates and local permeability....

Seismic Stability Analysis of Landfill
The failure mechanism of a waste containment system is not well understood due to the complexity and the heterogeneity of the system. The recent slope failure of the Kettleman Hills waste...

Environmental Aspects of Lunar Helium-3 Mining
Three potential detrimental effects of lunar ³He mining have been identified; visual changes, atmospheric contamination, and solid waste disposal....

Steady State Composition with Low Fe?⁺ Concentrations for Efficient O₂ Production by Magma Electrolysis of Lunar Soils
Parameters are estimated for a hypothetical, well stirred, continuous-feed electrolytic cell that converts 20% of a lunar soil feedstock to O₂ gas,...

Regenerative Life Support Technology Challenges for the Space Exploration Initiative
Regenerative life support systems have been identified as one of the critical enabling technologies for future human exploration of space. This discipline encompasses processes and subsystems...

Launch Facilities as Infrastructure
Many of the launch facilities in this country impose inefficiencies on launch service providers due to the way they have been constructed. To improve launch operation efficiency and to...

A Novel University-Industry-Government Partnership
The Ohio Aerospace Institute (OAI) is a Consortium of nine universities in Ohio, the NASA Lewis Research Center (LeRC) in Cleveland, the Wright Laboratory (WL) at the Wright Patterson...

Traffic Impact Assessment for Snow Disposal Facilities?Extended Abstract
Snow disposal facilities perform an integral role in the maintenance programs of many municipalities in canada and other northern countries. The most popular type of snow disposal facility...

Solid Waste Travel Demand Model Using GIS and Simulation for Evaluating Site Impacts
This study accomplishes two objectives: (1) develops a model to forecast future household travel demands for a given solid waste site in Fairbanks, Alaska and (2) develops precursory techniques...

Estuarine Environmental Impact Assessment Using a Three-Dimensional Circulation and Transport Model
Two case studies of estuarine environmental impact assessment using a recently developed three-dimensional circulation and transport model are presented following a brief overview of the...

Capturing Capital
Over the past few years, the environmental engineering and consulting business has become capital intensive. Between 1991 and 1993, firms' incremental capital needs will total...

The Future Role of Factory Built Housing
For most of this century, and particularly around 1970 as epitomized by Operation Breakthrough, the concept of transitioning the US housing industry from stick-by-stick field building...

Performance Specifications for the Design and Manufacture of Energy Efficient Housing in the 21st Century
This paper reports on work in progress in `Design for Energy Efficiency', one of fifteen task areas of the U.S. Department of Energy sponsored Energy Efficient Industrialized Housing research...

Responding to Public Opinion About Cumulative Long-Term Risks: Analysis and Communication of Risks from Climate Change and Hazardous Waste Sites
Public reactions to cumulative, uncertain, and long-term (CULT) risks pose particular problems to risk communicators. Low-magnitude and low-probability risks (e.g., living next to a hazardous...
