Radiochemical analysis of the first plateout probe from the Fort St. Vrain high-temperature gas-cooled reactor

Description: This report presents the analysis of radioactive elements on the first plateout probe from the Fort St. Vrain high-temperature gas-cooled reactor. The plateout probe is a device which samples the primary coolant for condensible fission products. Circuit inventories of individual radionuclides are estimated from the probe analysis. The analysis shows that the radioactive contamination in the primary circuit is remarkable low, with activation product concentrations much greater than that of fissi… more

Molecular biological enhancement of coal biodesulfurization. [Rhodococcus, thiobacillus]

Description: The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: clone and characterize the genes encoding the enzymes of the 4S'' pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; return multiple copies of genes to the original host to enhance the biodesulfurization activity of that organism; transfer this pathway into a fas… more

Variations in volatiles in magma bodies based on studies of melt inclusions

Description: Knowledge of volatile concentrations in magmas are important in the prediction of explosive volcanism, and contribute to the understanding of the carbon dioxide budget of the atmosphere. Some important variables that are controlled by volatiles are: crystallization temperature of phases, composition of liquids minimum, and viscosity. Volatiles are also catalysts for reactions.

Feasibility Studies of in-Situ Coal Gasification in the Warrior Coal Field. Quarterly Report

Description: Because of high internal temperatures, the external temperature has no effect upon the reaction rate of coke particles with air for temperatures above 750/sup 0/K. Reactions could not be initiated below that temperature. Chemical reaction rate was not found to be a rate-controlling step: both extra-particle and intra-particle diffusion are important and limit the rate of oxidation. The observed values of k/sub c/, the extra-particle mass transfer coefficient were found to be in good agreement w… more

Channel coincidence counter: version 1

Description: A thermal neutron coincidence counter has been designed for the assay of fast critical assembly fuel drawers and plutonium-bearing fuel rods. The principal feature of the detector is a 7-cm by 7-cm by 97-cm detector channel, which provides a uniform neutron detection efficiency of 16% along the central 40 cm of the channel. The electronics system is identical to that used for the High-Level Neutron Coincidence Counter.

Determination of low-level mercury by cold vapor generation and atomic absorption spectroscopy

Description: A procedure for determining mercury in liquid samples by cold vapor flameless atomic absorption spectroscopy was developed. The optimum parameter values were determined and mercury standard storage conditions investigated. The effect and tolerance levels of twenty-seven ions, including those ions common to Tank Farm Operations and the Synthetic Wastes, were measured. Standard deviation for the procedure is less than 1%. The procedure can be used to determine mercury at the part per billion leve… more

Recovery and purification of nickel-63 from HFIR-irradiated targets

Description: The production of large quantities of high-specific-activity [sup 63]Ni (>10 Ci/g) requires both a highly enriched [sup 62]Ni target and a long irradiation period at high neutron flux. Trace impurities in the nickel and associated target materials are also activated and account for a significant fraction of the discharged activity and essentially all of the gamma activity. While most of these undesirable activation products can be removed as chloride complexes during anion exchange, chromium, p… more

Comparison of acid leachate and fusion methods to determine plutonium and americium in environmental samples

Description: The Analytical Chemistry Laboratory at Argonne National Laboratory performs radiochemical analyses for a wide variety of sites within the Department of Energy complex. Since the chemical history of the samples may vary drastically from site to site, the effectiveness of any analytical technique may also vary. This study compares a potassium fluoride-pyrosulfate fusion technique with an acid leachate method. Both normal and high-fired soils and vegetation samples were analyzed for both americium… more

Reactivity of young chars via energetic distribution measurements

Description: We have developed what we believe to be the very first a priori prediction technique for the gasification reactivity of coal char. With this method the gasification reactivity of a coal char as function of temperature can be predicted from a single temperature programmed desorption (TPD) experiment following mild gasification at a single temperature (Calo et al., 1989; Hall and Calo, 1990a). This approach has been demonstrated for C0{sub 2} gasification of coal chars where the gasification reac… more

Characteristics of American coals in relation to their conversion into clean energy fuels. Quarterly technical progress report, January--March 1977

Description: Twenty-one coal samples have been added to the Penn State/ERDA Coal Sample Bank. Ninety-six sets of analytical data and 114 coal samples were provided upon request to other agencies engaged in coal research. Mass spectrometer and reactor systems have been used successfully in measuring the amount of vaporization (and pyrolysis) products of hydrocarbons in low concentrations in a helium carrier gas. Research has shown, using small angle x-ray scattering, that the pore structure of a char is a fu… more

Final report on proposal to develop and test a membrane sampling module for the extraction of volatile organic compounds from water

Description: A new technique is describe for the direct detection of volatile organic compounds in aqueous solutions at levels in the parts per trillion range. The sample is enriched in analyte in two consecutive stages, one utilizes a semi-permeable membrane interface and the other a jet separator. The analyte solution is sampled as it flows coaxially over a semi-permeable capillary membrane, the interior of which is continuously purged by helium. The permeate is pneumatically transported to the mass spect… more

Characterization of past and present solid waste streams from 231-Z

Description: During the next two decades the transuranic (TRU) wastes now stored in the burial trenches and storage facilities at the Hanford Site are to be retrieved, processed at the Waste Receiving and Processing Facility, and shipped to the Waste Isolation Pilot Plant near Carlsbad, New Mexico for final disposal. Over 8% of the TRU waste to be retrieved for shipment to the Waste Isolation Pilot Plant has been generated at the Plutonium Metallurgy Laboratory (231-Z) Facility. The purpose of this report i… more

Volatilized tritiated water vapor in the vicinity of exposed tritium contaminated groundwater

Description: Water vapor tritium concentrations in air above a known source of tritiated water can be estimated. Estimates should account for the mechanisms of evaporation and condensation at the water surface and water species exchange, and are typically applicable under a broad range of wind, temperature and humidity conditions. An estimate of volatilized tritium water vapor was made for a known outcropping of tritium contaminated groundwater at the Savannah River Site (SRS) old F-Area effluent stream. In… more

Shale oil value enhancement research. First quarterly technical progress report, March 1, 1993--May 31, 1993

Description: Concurrent progress is being made in all key areas, namely, separation, characterization and market assessment. The market area, not one of our traditionally strong areas, has been going better than expected. We believe this is due mainly to the emerging interest in new and unconventional materials. The characterization work has been progressing solidly with the fundamental Z-BASIC correlations providing information not heretofore available in the chemical literature. Our agreement with Hewlett… more

Radiochemical analyses of soil and vegetation samples taken from the Hanford environs, 1971--1976

Description: Soil and vegetation have routinely been collected on the Hanford Site and surrounding environs as one method of monitoring radionuclide concentrations potentially attributable to Hanford operations. With the exception of a few locations, the data indicate that Hanford operations have made no significant contribution to existing radionuclide concentrations in soil and vegetation. Most of the activity seen in the samples can be attributed to natural causes or worldwide atmospheric fallout. The fe… more
