Demonstration of selective catalytic reduction (SCR) technology for the control of nitrogen oxide (NO sub x ) emissions from high-sulfur coal-fired boilers

Description: The objective of this project is to demonstrate and evaluate commercially available Selective Catalytic Reduction (SCR) catalysts from US, Japanese and European catalyst suppliers on a high-sulfur US coal-fired boiler. SCR is a post-combustion nitrogen oxide (NOx) control technology that involves injecting ammonia into the flue gas generated from coal combustion in an electric utility boiler. The flue gas containing ammonia is then passed through a reactor that contains a specialized catalyst. … more

The influence of interfacial properties on two-phase liquid flow of organic contaminants in groundwater

Description: An improved understanding of the factors influencing the movement of a separate organic liquid phase in groundwater aquifers is important to the US Department of Energy's efforts to alleviate groundwater contamination by many common solvents. The overall objective of this project is to investigate how changes in interfacial chemical properties affect two-phase flow relationships. Specifically, the objective is to develop a quantitative theory that will enable the prediction of changes in the ca… more

sup 31 P NMR analysis of coal moieties bearing -OH, -NH, and -SH functions

Description: NMR reagents for the speciation and quantitation of labile-hydrogen functional groups and sulfur groups in coal ligands have been synthesized and evaluated. These reagents, which contain the NMR-active nuclei {sup 31}p, {sup 119}Sn or {sup 195}pt, were designed to possess improved chemical shift resolution over reagents reported in the literature. Our efforts were successful in the case of the new {sup 31}p and {sup 119}Sn reagents we developed, but the {sup 195}pt work on sulfur groups was onl… more

F/H Area ETF effluent (H-016 outfall) ceriodaphnia survival/reproduction test, test date: June 17, 1989

Description: This study was conducted to determine if Savannah River Plant effluents cause death (acute toxicity) or reduction in the reproduction of the test organisms (chronic toxicity) during a seven day exposure period. A series of dilutions of the effluent were used to determine how much the effluent must be diluted before toxic effects are no longer noted.

Iron yoke eddy current induced losses with application to the ALS septum magnets

Description: The theoretical development of relations governing the eddy current induced losses in iron electromagnet yokes is reviewed. A baseline laminated electromagnet design is analyzed and a parametric study illustrates the sensitivity of core losses to perturbations of various geometrical, material, and excitation parameters. Core losses and field gradients for the ALS septum magnets are calculated. Design modifications capable of eliminating transverse and longitudinal field gradients are discussed.

Brine Sampling and Evaluation Program, 1990 report

Description: The data presented in this report are the result of Brine Sampling and Evaluation Program (BSEP) activities at the Waste Isolation Pilot Plant (WIPP) during 1990. When excavations began in 1982, small brine seepages (weeps) were observed on the walls. These brine occurrences were initially described as part of the Site Validation Program. Brine studies were formalized in 1985. The BSEP activities document and investigate the origins, hydraulic characteristics, extent, and composition of brine o… more

Procedure for separation of Se and determination of Se-79 by liquid scintillation

Description: This report describes the development work and demonstration of a technique for separation of selenium suitable for determination of Se-79 by liquid scintillation counting. The technique has been demonstrated on actual DWPF (Defense Waste Processing Facility) sludge samples which contain very large loads of Sr-90 activity. The separation required a decontamination of selenium from Sr by a factor of over 10{sup 6}, from Co and Cs by factor of 10{sup 4}, and from Tc-99 by a factor of 100, while s… more

Interband transitions in YBa{sub 2}Cu{sub 3}O{sub 7}

Description: Using rotating analyzer ellipsometry, we have measured all three components of the dielectric tensor of YBa{sub 2}CU{sub 3}O{sub 7} from near-infrared to vacuum-ultraviolet (0.7 -- 24 eV). In the low energy region the spectra for a -- b polarization can be well modelled by a Drude free-carrier response with a frequency independent scattering rate. Below 10 eV we observe strongly anisotropic interband transitions involving the partially filled valence band and the conduction band. At higher ener… more

NO{sub x} Abatement Pilot Plant 90-day test results report

Description: High-level radioactive liquid wastes produced during nuclear fuel reprocessing at the Idaho Chemical Processing Plant are calcined in the New Waste Calcining Facility (NWCF) to provide both volume reduction and a more stable waste form. Because a large component of the HLW is nitric acid, high levels of oxides of nitrogen (NO{sub x}) are produced in the process and discharged to the environment via the calciner off-gas. The NO{sub x} abatement program is required by the new Fuel Processing Rest… more

Comparison of the corrosion rates of FeAl, Fe{sub 3}Al and steel in distilled water and 0.5 M sodium chloride. Technical report number 2, January--March 1991

Description: The corrosion rate of an Fe{sub 3}Al alloy (FA117) and an FeAl (FA362) alloy in distilled water and 0.5 M NaCl was determined and compared to two low carbon steels. The results demonstrate that the corrosion rate of these two intermetallic compounds were more than an order of magnitude less than that of the two steels in both of the environments. The corrosion rates of the two iron aluminides were not significantly different.

Thin Polymer Icemaker Development and Test Program. Final Report on Technology

Description: We have constructed and tested a small device to produce ice in ice/water mixtures using a cold fluid as the heat sink. The device is a flexible heat exchanger constructed from a thin film of a suitable polymer. When filled with circulating liquid coolant the heat exchanger consists of an inflated series of parallel tubes; ice forms on the outside in complementary half cylinders. When the circulation is cut off, gravity drains the coolant and the static head of the water bath crushes the tubes,… more

Evaluation of the electrochemical behavior of ductile nickel aluminide and nickel in a pH 7.9 solution

Description: The electrochemical behavior of ductile doped nickel aluminide has been examined in neutral solutions. Features observed in a certain potential range were characterized, and the potentiodynamic sweep parameters affecting them identified. Nickel aluminide behaves essentially as pure nickel; however, small differences were observed.
