We have made a detailed study of the care that must be taken to correctly measure OH radical concentrations in flames. A large part of these studies has concerned collisional quenching of hydride radical species (OH, NH, and NH{sub 2}), in particular the dependence upon rotational level and collision velocity (temperature). The results on OH and NH have shown unique and interesting behavior from the viewpoint of fundamental molecular dynamics, pointing to quenching often governed by collisions on an anisotropic, attractive surface, whereas NH{sub 2} quenching appears to depend on state-mixing considerations, not dynamic control. This state-specific behavior of these small, theoretically tractable hydrides has direct ramifications for quantitative flame diagnostics. Our other effort in the diagnostic area has been repeated but unsuccessful searches for laser induced fluorescence in the vinyl radical.

The purpose of the present program is to develop soluble analogs of surface confined catalysts that can be impregnated directly into the coal structure at low temperatures. This approach should avoid problems related to surface area dependence, a two phase (surface-liquid) reaction system and, mass transport limitations.

Research programs from the National Institute for Petroleum and Energy Research (NIPER) are briefly described.

The overall objectives of this program are to investigate potential technologies for the conversion of coal-derived synthesis gas to oxygenated fuels, hydrocarbon fuels, fuel intermediates, and octane enhancers, and to demonstrate the most promising technologies at DOE's LaPorte, Texas, Slurry Phase Alternative Fuels development Unit (AFDU). The program will initially involve a continuation of the work performed under the Liquid Phase Methanol Program but will later draw upon information and technologies generated in current and future DOE-funded contracts, as well as test commercially available catalysts. 1 fig., 3 tabs.

The traveler visited the Joint Research Centre (JRC), Petten, The Netherlands, the Forschungszentrum GmbH (KFA), Juelich, Germany; and the Zentralinstitut fuer Kernforschung (ZfK), Rossendorf, Germany, during the period January 28 through February 9. At JRC, the analysis of the experiment HFR-B1 was discussed; a new schedule for issuance of the final data report was established. Other discussions at JRC concerned the capabilities of Petten to conduct two reactor experiments being proposed under the US/FRG cooperative program and the initial results of a proof test of Germany fuel spheres. At KFA, the main emphasis was on the disassembly of capsules 2 and 3 of the HFR-B1 experiment and agreement on the examinations and tests to be conducted with the disassembled components. The disassembly of capsule 3 was observed. Extensive discussions were conducted on the work, both experimental and analytical, being conducted in the Institut fuer Sicherheitsforschung und Reaktor Technologie. A major portion of the experimental work is being conducted at ZfK and a visit to this laboratory, sponosored by the KFA, was made on February 6 and 7. Cooperation with the US on the experimental and analytical work in the safety area was strongly emphasized. 1 tab.

The Coal Project was able to make considerable progress in understanding the evolving energy situation in Asia and the future role of coal and Clean Coal Technologies. It is clear that there will be major growth in consumption of coal in Asia over the next two decades -- we estimate an increase of 1.2 billion metric tons. Second, all governments are concerned about the environmental impacts of increased coal use, however enforcement of regulations appears to be quite variable among Asian countries. There is general caution of the part of Asian utilities with respect to the introduction of CCT's. However, there appears to be potential for introduction of CCT's in a few countries by the turn of the century. It is important to emphasize that it will be a long term effort to succeed in getting CCT's introduced to Asia. The Coal Project recommends that the US CCT program be expanded to allow the early introduction of CCT's in a number of countries.

I have investigated trigger requirements for the intermediate tracking system of the SDC detector, using muons in the final states of some physics processes of interest and relevance to the program envisaged to be pursued at the SSC. The study is done at the physics event generator level with the PYTHIA package, augmented by a very simplistic simulation of the momentum measurement expected from the intermediate tracking system. For the range in pseudorapidity of {vert bar}{eta}{vert bar} = 1.7--2.5, I find a subdivision into four basic bins sufficient to ensure that the width of the transverse momentum trigger threshold will not be dominated by the lack of knowledge of the polar angle. In addition, the azimuthal resolution has be better than 1 mrad to allow transverse momentum thresholds from p{sub t}{approx}10 GeV/c up to and beyond p{sub t}=20 GeV/c to be implemented which are needed to accomplish the physics goals. 10 figs., 1 tab.

A DYNA3D model of the DT-20 shipping container was constructed. Impact onto a rigid steel surface at a velocity of 44 ft/sec (30 foot gravity drop) was studied. The orientation of most interest was a side-drop, but end and corner drops were also studied briefly. The assembly for the baseline side impact contained a 150 lb. payload. During this drop, the outer drum sustains plastic strains of up to 0.15, with most the deformation near the rim. The plywood/Celotex packing is crushed about 3 inches. The inner sealed can sees significant stresses, but barely reaches the onset of yielding in some local areas. Based on hand calculations, the bolts joining the can halves could see stresses near 50 ksi. It is felt that overall, the container should survive this drop. However, detailed modeling of the rim closure and the center bolted joint was not possible due to time constraints. Furthermore, better material models and properties are needed for the Celotex, plywood, and honeycomb in particular. 39 figs., 1 tab.

Acceptance criteria for uranium check standards used to verify fluorimeter calibration have been developed. This work was done in response to Tiger Team finding QA/BMP-5, item 4.

Despite the rise in petroleum products prices, a colder-than-normal winter in the latter part of 1989 spurred an increase in demand for distillate fuel oils. The shipping and electric utilities industries contributed to a significant rise in demand for both distillate and residual fuels oils in 1989. A total of 72.9 billion gallons of fuel oil and kerosene were sold to consumers in 1989, an increase of 3.0 percent over 1988 sales volumes. Of all fuel oil sold during 1989, distillate fuel oil accounted for 68.3 percent, which was an increase over 1988 when distillate fuel oil accounted for 67.2 percent of all fuel oil products sold in the United States. Residual fuel oil's share of total fuel oil sold fell slightly to 29.9 percent from 30.7 percent in 1988. Kerosene followed with a 1.8 percent share, also falling from the previous year when it accounted for a 2.1 percent share of total fuel oil sold. 3 figs., 24 tabs.

Radian Corporation was contracted to investigate duct injection and electrostatic precipitator phenomena in a 1.7-MW pilot plant constructed for this test program. This study was an attempt to resolve previous problems and to answer remaining questions with the technology using an approach which concentrated on the fundamental mechanisms of the process. The goal of the study was to obtain a better understanding of the basic physical and chemical phenomena that control: (1) the desulfurization of flue gas by calcium-based reagent, and (2) the coupling of the duct injection process to an existing ESP particulate collection device.

Tests were conducted to determine whether the reverse osmosis (RO) units at the F/H Effluent Treatment Facility (ETF) at the Savannah River could be made to process solutions containing tri-n-butyl phosphate (TBP). It was desired to test whether operation at a feed pH other than neutral would improve performance. Test results are discussed in this report and indicate that little improvement in the water flux can be expected at other pH values.

The simplest explanation for these shifts in the infrared spectra is there exists in coal single electron donors which are capable of transferring an electron to TCNQ in the ground state. All of the TCNQ placed in the coal appears to be converted to the radical anion as displayed in the IR spectrum for all of the coals except for the 100% loading.

Several potential additives and the use of influent pH adjustment were examined to remediated the biofouling problem of the ETF reverse osmosis (RO) system. Tests were conducted with simulated RO feed containing salt, metal hydroxides and bacteria. The addition of sodium hexametaphosphate (SHMP), sodium bisulfite, and adjusting the influent pH to 3 were each successful in reducing the RO biofouling. Little or no benefit was found from the use of a biofilm remover (Filmtec Alkaline Cleaner) or the use of surfactants (Surfynol or sodium lauryl sulfate). In addition, Surfynol use resulted in irreversible fouling and necessitated membrane replacement. At the water recoveries used in the ETF (>90%), sodium bisulfite addition resulted in the recovery of 70--90% of the flux and almost complete restoration of the DF to prefouled conditions. Based on the bench-scale tests completed, IWT would recommend that sodium bisulfite addition be tested at the ETF. This testing would involve optimizing the amount of bisulfite required. In addition, it is recommended that the addition of SHMP or influent pH adjustment be evaluated since the relative differences in labscale tests were small and scale-up effects could be present. The ETF operating permit allows each to be added.

The D0 cryogenic control system is a complicated system with many facets. Because of the large number and variety of features in the system, a series of ongoing control system training seminars, or control classes, were created in order to keep people up to date on the operation of the system. As of the writing of this engineering note, there have been four classes. The original lecture notes from each class can be found in the cryogenic control room at the D0 Assembly Building, or in the Co-op office. This note provides a summary of the first three control classes, and it includes the entire set of notes from the fourth class, which was held in April of 1990. This class was taught by Jeff Wendlandt and Dan Markley. Dan should be consulted for more complete explanations than those given in the notes. The notes are, in fact, more of a reference for someone who has some experience with the system, than they are a training manual. Most of the pages include pictures and printouts of different menus and functions, useful for finding details without searching through the actual program. In general, this note serves as a pointer to the …

AISI Type 304L (304L) stainless steel was recommended as a suitable material of construction for the new Hazardous Low Level Waste Processing Tanks (HLLWPT). This report documents the second phase of a coupon immersion test program to determine the susceptibility of 304L to localized attack in a variety of simulated wastes. The coupon test results confirmed the conclusions that were made from the first phase of the test program. First, 304L is a suitable material of construction for the new waste tanks. Second, the agreement between the cyclic polarization tests and the coupon immersion tests demonstrates that cyclic polarization can be used to predict the susceptibility of a material to localized corrosion in these wastes. In addition to the tests performed on 304L, tests were performed on ASTM A537 carbon steel (A537) and Incoloy 825 (I825). Neither 304L nor I825 was susceptible to attack, while A537 experienced varying degrees of attack in the different wastes. Observations on the surface attack and corrosion products on A537 were used to elucidate the mechanism by which A537 corrodes in these wastes.
