EPRI Journal archives from April 1993

Genetic inducers enhance toxic waste cleanup. (Discovery)
April 1, 1993... The emerging science of genetic ecology seeks to genetically amplify the activity of naturally occurring microorganisms in order to break toxic substances at contaminated sites down into harmless forms. This effort has usually involved...

Conductive plastics light up experimental LEDs. (light-emitting diodes) (Discovery)
April 1, 1993... Conductive polymers, which combine some of the electronic and optical properties of semiconductors characteristics of plastics, have already begun to revolutionize certain niche markets for electrica specialized sensors and small, high-energy...

The vision of distributed generation. (distributed system of power generation)
April 1, 1993... THE STORY IN BRIEF The strategic use of small generation units at or near the premises of electric utility customers--a concept called distributed generation--is a hot topic among utilities today. Increased competition, technological advances,...

EMF in American homes. (electric magnetic field)
April 1, 1993... Although public concern about exposure to electric and magnetic fields (EMF) has risen because of recent epidemiologic studies, little is known about the major EMF sources and average field levels in homes. To provide such information, EPRI has...

Videoconferencing: face to face at a distance. (compressed digital videoconferencing)(includes related article)
April 1, 1993... Every Tuesday morning Rick Squires takes a three-minute walk from his office in Palo Alto, California, and spends an hour and a half with his colleagues at PowerGen, near Nottingham, England. He's back at his desk well before lunch. Squires, a...

New approaches hold promise for groundwater cleanup. (Electrotechnology Applications)
April 1, 1993... EPRI researchers are exploring two innovative applications of electrotechnologies to attack the costly and difficult problem of groundwater cleanup. One approach, using electromigration of dissolved chemicals, shows "very high promise,"...

Superconducting storage may keep BART trains running. (Bay Area Rapid Transt) (Power Quality)
April 1, 1993... The use of mass transit in the San Francisco Bay Area has increased significantly since the inception of the Bay Area Rapid Transit (BART) system 20 years ago. And with today's high levels of transit and electrical system loading, the system...

Innovative methods could help restore shad to the Susquehanna. (Susquehanna River) (In The Field)
April 1, 1993... Efforts to reverse the toll of a century of development, pollution, and overfishing could help restore large numbers of juvenile American shad to the Susquehanna River's upper reaches. During the fall out-migration, young fish must pass through...

Tracer leak detector goes to work in the real world. (In The Field)
April 1, 1993... Consolidated Edison Company of New York operates one of the largest underground transmission and distribution systems in the world, including the longest lengths of pipe-type, fluid-filled transmission cable. In such a dense urban area as New...

FGD materials guidelines and software. (flue gas desulfurization) (Fossil Plant SO2 Control)
April 1, 1993... Over the past 10 years, EPRI has committed a substantial portion of its annual research budget in the area of flue gas desulfurization (FGD) to the investigation and resolution of problems with the materials of construction used in FGD. Results...

Continuous emissions monitoring. (air pollution emissions) (Fossil Plant Air Quality Control)
April 1, 1993... The continuous monitoring of air pollution emissions is one of the most immediate and complex requirements of the 1990 Clean Air Act Amendments (CAAA). Virtually all U.S. fossil-fuel-fired electric utility plants are now subject to legal...

Biological approaches to reducing atmospheric CO2. (Exploratory Research)
April 1, 1993... The atmospheric concentration of carbon, in the form of carbon dioxide ([CO.sub.2]), is increasing at a rate of approximately 3.5 billion metric tons (Gt), or 0.5%, a year. This increase is of concern to utilities because fossil fuel combustion...

Seismic verification of nuclear plant equipment. (Nuclear Safety)
April 1, 1993... In recent years, nuclear plant operation and maintenance (O&M) costs have generally risen at a rate considerably higher than the rate of inflation. A number of factors have contributed to this rapid cost escalation, including new regulatory...
