Proton resonance spectroscopy. Progress report, December 1, 1991--November 30, 1992

Description: Preparations for studying {sup 30}P via {sup 29}Si(p,{gamma}) have continued. We are exploring both the use of the Fourier transform and the statistical behavior of electromagnetic transition strengths within the shell model as alternate approaches to identifying quantum chaos in nuclei. Analysis of interfering resonances in (p,{alpha}) resonances suggests that improvements in the limits on detailed balance in nuclear reactions are possible, but several issues still must be considered before a … more

Single molecule detection using charge-coupled device array technology. Technical progress report

Description: A technique for the detection of single fluorescent chromophores in a flowing stream is under development. This capability is an integral facet of a rapid DNA sequencing scheme currently being developed by Los Alamos National Laboratory. In previous investigations, the detection sensitivity was limited by the background Raman emission from the water solvent. A detection scheme based on a novel mode of operating a Charge-Coupled Device (CCD) is being developed which should greatly enhance the di… more

Definitive evaluation of Wheeler Reservoir sedments toxicity using juvenile freshwater mussels (Andodonta imbecillis Say)

Description: Reservoir sediments near the Decatur, Alabama, industrial waterfront were screened for acute (9-day) toxicity to 8-day old freshwater mussels In 1990. only two locations, designated as stations Alpha (TRM 303.4L, Dry Branch Embayment) and Delta (TRM 301.lL), were found to be toxic to mussels. Toxicity correlated strongly with unionized ammonia measured daily In porewater samples during the study. A definitive study was conducted in 1991 to determine persistence of the toxicity observed In 1990 … more

Chemical activation of molecules by metals: Experimental studies of electron distributions and bonding. Progress report, March 1, 1992--September 30, 1992

Description: Purpose of this research program is to obtain experimental information on the different fundamental ways metals bond and activate organic molecules. Our approach has been to directly probe the electronic interactions between metals and molecules through a wide variety of ionization spectroscopies and other techniques, and to investigate the relationships with bonding modes, structures, and chemical behavior. During this period, we have (1) characterized the electronic features of diphosphines a… more

Flue gas desulfurization gypsum and fly ash

Description: The Cumberland Fossil Plant (CUF) is located in Stewart County, Tennessee, and began commercial operation in 1972. This is the Tennessee Valley Authority`s newest fossil (coal-burning) steam electric generating plant. Under current operating conditions, the plant burns approximately seven million tons of coal annually. By-products from the combustion of coal are fly ash, approximately 428,000 tons annually, and bottom ash, approximately 115,000 tons annually. Based on historical load and projec… more

Chickamauga reservoir embayment study - 1990

Description: The objectives of this report are three-fold: (1) assess physical, chemical, and biological conditions in the major embayments of Chickamauga Reservoir; (2) compare water quality and biological conditions of embayments with main river locations; and (3) identify any water quality concerns in the study embayments that may warrant further investigation and/or management actions. Embayments are important areas of reservoirs to be considered when assessments are made to support water quality manage… more

Field performance of cavitation erosion resistant alloy on pumped-storage hydroturbine

Description: The TVA Raccoon Mountain Plant is a four unit pumped-storage plant located on the Tennessee River, Nickajack Reservoir, in Marion County, Tennessee, six miles (3.7 km) west of Chattanooga, Tennessee. The four units went into commercial operation between January 31, 1978 and August 31, 19179. Each unit has a generating rating of 392 MW at a 1020 ft head (310.9 meters). Each turbine is a reversible Francis type, with vertical shaft, manufactured by Allis-Chalmers (now Voith Hydro, Inc.). The runn… more

Air Quality Analysis and Related Risk Assessment for the Bonneville Power Administration's Resource Program Environmental Impact Statement

Description: The Bonneville Power Administration (BPA) is considering 12 different alternatives for acquiring energy resources over the next 20 years. Each of the alternatives utilizes a full range of energy resources (e.g., coal, cogeneration, conservation, and nuclear); however, individual alternatives place greater emphases on different types of power-producing resources and employ different timetables for implementing these resources. The environmental impacts that would result from the implementation o… more
