Consolidated Incineration Facility metals partitioning test. Final report

Description: Test burns were conducted at Energy and Environmental Research Corporation`s rotary kiln simulator, the Solid Waste Incineration Test Facility, using surrogate CIF wastes spiked with hazardous metals and organics. The primary objective for this test program was measuring heavy metals partition between the kiln bottom ash, scrubber blowdown solution, and incinerator stack gas. Also, these secondary waste streams were characterized to determine waste treatment requirements prior to final disposal… more

Electron acceleration by laser fields in a gas. Technical progress report

Description: Both the 50-MeV electron accelerator and the short-pulse CO{sub 2} laser have become operational, and preliminary tests have already been performed involving electrons and shaped lasers beams inside a gas cell. Theoretical work has been performed on the topic of interaction region synthesis and on FEL-type devices involving a gas medium and no wiggler structures. Appendixes present some of the results.

F/H seepage basin groundwater process tank settling characterization task technical plan

Description: The Environmental Restoration (ER) Department is responsible for environmental remediation projects on Site at the Savannah River Plant. ER requested Interim Waste Technology Section (IWTS) to conduct a treatability study to develop a system which would reduce the ground water contaminant levels in the aquifers at the F/H seepage basins. A task technical plan has been initiated to support the remediation system development. The task plan provides the methodology for conducting further investiga… more

Formation and emission of methane in rice soils: Experimental determination and modeling analysis. Final report

Description: Rice paddy soils have been identified as a major source of methane emissions contributing to the observed atmospheric increase in methane. This points to the need for a method of quantifying and predicting methane emissions for the widely varying conditions used in rice agriculture throughout the world. In the present work, a mathematical model for estimating the emission of methane from rice paddy soils is developed and refined. Kinetic parameters for methanogenesis in a Louisiana rice soil ar… more

Microbiology and physiology of anaerobic fermentation of cellulose. Annual report for 1990, 1992, 1993 and final report

Description: This report focuses on the bioconversion of cellulose to methane by various anaerobes. The structure and enzymatic activity of cellulosome and polycellulosome was studied in Clostridium thermocellum. The extracellular enzymes involved in the degradation of plant material and the physiology of fermentation was investigated in anaerobic fungi. Enzymes dealing with CO, CO{sub 2}, H{sub 2}, CH{sub 3}OH, as well as electron transport and energy generation coupled to the acetyl-CoA autotrophic pathwa… more

Surfactant loss control in chemical flooding: Spectroscopic and calorimetric study of adsorption and precipitation on reservoir minerals. Quarterly technical progress report, April 1, 1993--June 30, 1993

Description: The aim of this contract is to elucidate the mechanisms underlying adsorption and surface precipitation of flooding surfactants on reservoir minerals. The results of this study should help in controlling surfactant loss in chemical flooding and also in developing optimum structures and conditions for efficient chemical flooding processes. Adsorption of single surfactants on silica and alumina as well as the solution behavior of surfactant mixtures was studied during this quarter. The adsorption… more

Test and analysis of canister-frame connections

Description: A finite element analysis was performed for the structural connections of a downhole nuclear test emplacement assembly. The bolt loads as well as the stresses in the cable trays and end plates of the assembly were examined for a range of bolt preloads and applied external axial loads. The focus of this study was the effects of preload on the bolt load and the stresses in various parts of the assembly. The effects of bolt size and door strap were also examined. A full-scale pull test of the stru… more
