We have been using the 3d PIC code WARP6 to model the behavior of beams in a heavy ion induction accelerator; such linacs are candidates for an ICF driver. Improvements have been added to the code to model an axially confined beam using comoving axial electric fields to simulate the confining ears'' applied to the accelerating pulses in a real system. We have also added a facility for modeling a beam in a round pipe, applying a capacity matrix to each axial Fourier mode in turn. These additions are described along with results, such as the effect of pipe shape on the beam quality degradation from quadrupole misalignments. 5 refs., 6 figs., 1 tab.

This project is designed to develop methods for precombustion coal remediation by implementing recent advances in enzyme biochemistry. The novel approach of this study is incorporation of hydrophilic oxidative enzymes in reverse micelles in an organic solvent. Enzymes from commercial sources or microbial extracts are being investigated for their capacity to remove organic sulfur from coal by oxidation of the sulfur groups, splitting of C-S bonds and loss of sulfur as sulfuric acid (Figure 1). Dibenzothiophene (DBT) and ethylphenylsulfide (EPS) are serving as models of organic sulfur-containing components of coal in initial studies. A goal of this project is to define a reverse micelle system that optimizes the catalytic activity of enzymes toward desulfurization of model compounds and ultimately coal samples. 12 refs., 2 figs., 7 tabs.

The argon storage dewar at the D0 Assembly Hall was filled with approximately 3100 gallons of high purity liquid argon for the first time on December 3,1990. The oxygen analyzer and high voltage test cell both indicated an oxygen impurity level between 0.4 and 0.5 ppm which is acceptable. The condenser and insulated piping sizing appears to be correct for a fill rate of a couple of hours. Insulation is required around the inlet to this piping in order to reduce the amount of filling time significantly. The graph of the level indication vs. volume of the dewar should be changed to reflect the apparent 5.2-5.4 in. offset. Another data point may be required to narrow this number down further. A majority of the time spent to fill the vessel was associated with the testing of the liquid-this time will shorten as we gain experience. Subsequent deliveries should be ordered to initiate as early in the morning as possible, this appears to be nearly an all day effort. The argon checked prior to delivery by us indicated that it was acceptable. The analysis of the argon purity that Linde provides us is merely a check that the liquid meets our …

The Coal Distribution report provides information on coal production, distribution, and stocks in the United States to a wide audience including Congress, Federal and State agencies, the coal industry, and the general public. The data in this report are collected and published by the Energy Information Administration (EIA) to fulfill its data collection and dissemination responsibilities as specified in the Federal Energy Administration Act of 1974 (Public Law 93-275, Sections 5 and 13, as amended). This issue presents information for January through June 1991. Coal distribution data are shown (in Tables 1--34) by coal-producing Sate of origin, consumer use, method of transportation, and State of destination. All data in this report were collected by the EIA on Form EIA-6, Coal Distribution Report.'' A copy of the form and the instructions for filing appear in Appendix B. All data in this report for 1991 are preliminary. Data for previous years are final. 6 figs., 34 tabs.

Initial synthesis work has focused on preparation of fine-particle iron-based compounds using an Fe(CO){sub 5} precursor. Fe(CO){sub 5} was chosen because of the liability of the carbonyl ligands with respect to substitution under either moderate thermal or photochemical reaction conditions. Six synthesis attempts have been carried out with Fe(CO){sub 5} using CS{sub 2} as the sulfur source; they are outlined here.

The temperature of a char particle burning in an oxygen containing atmosphere is the product of a strongly coupled balance between particle size and physical properties, heat transfer from the particle, surface reactivity, CO/CO{sub 2} ratio and gas phase diffusion in the surrounding boundary layer and within the particle. CO{sub 2}/CO ratios can be strongly influenced by catalytic material in the carbon and by the char temperature. In this program we are measuring the CO{sub 2}/CO ratio for both catalyzed and uncatalyzed chars over a wide range of temperature. These results will then be used to develop predictive models for char temperature and burning rates. The electrodynamic balance has been successfully used to make such measurements for single 200 {mu}m spherocarb particles. This work has been previously reported (progress reports 1 and 2). The electrodynamic balance has been rebuilt to improve its performance including: (1) Better control of gas flow and composition, (2) High pressure operation capability, (3) Advanced imaging system for size measurement and position determination (4) Capability of high and low temperature measurement, (5) Better position control, (6) Fast computation and memory facilities, (7) Better laser power control. In this report, progress on the calibration of the imaging …

Thirty-three waste drums were returned to Rocky Flats in support of EG G Idaho's quality control program for the Stored Waste Examination Pilot Plant. The drums were opened and examined in the size reduction facility at the Rocky Flats Plant. Contents of each drum were consistent with the Item Description Codes; however, four sludge drums and one combustible drum contained free liquids. These five drums failed to meet the Waste Isolation Pilot Plant and the Department of Transporation criteria. The proper amount of cement was not used in the sludge drums. A cemented layering process, which also contributed to accumulation of free liquid, is no longer used when cementing sludges at the Rocky Flats Plant. The drum of combustibles contained a polyethylene bottle with a small amount of liquid sludge inside. 2 refs., 2 tabs.

Radian Corporation was contracted to investigate duct injection and ESP phenomena in a 1.7 MW pilot plant constructed for this test program. This study was an attempt to resolve problems found in previous studies and answer remaining questions for the technology using an approach which concentrates 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 an existing ESP particulate collection device to the duct injection process. Process economics are being studied by others. (VC)

The overall strategy for this project is to allow for the earliest startup with a minimum of up front costs attributed to plant modifications. The plan is to implement only those modifications that are required in order that the plant can be operated in an integrated continuous manner and defer other modifications that will improve plant operation until needed. The necessary modifications are those affecting the operation of the vacuum filters and the evaporator that are critical to integrated operation. Analysis of the data from the one week of continuous around-the-clock testing plant showed 87% SO{sub 2} reduction and 93% ash removal while retaining 30% volatiles content. However, problems with filtration during the June test run (high level of coal fines) indicated that there was evidence that the Pittsburgh coal in our inventory might be weathered. Coal sample analysis showed an increase in sulfate sulfur and a decrease in heating value, also indicative weathering. TRW is proceeding with obtaining fresh coal to avoiding the problems associated with weathering. Approximately 4420 gallons of liquid wastes were shipped off-site for disposal during this reporting period. TRW is making plans to dispose of the remaining liquids and coal/caustic solids from the previous program. …

Nondestructive examination (NDE) of waste matrices using penetrating radiation is by nature very subjective. Two candidate systems of examination have been identified for use in WRAP 1. This test plan describes a method for a comparative evaluation of different x-ray examination systems and techniques.

We are continuing a research program in particle astrophysics and high energy experimental particle physics. We have joined the DUMAND Collaboration, which is constructing a deep undersea astrophysical neutrino detector near Hawaii. Studies of high energy hadronic interactions using emulsion chamber techniques were also continued, using balloon flight exposures to ultra-high cosmic ray nuclei (JACEE) and accelerator beams. As members of the DUMAND Collaboration, we have responsibility for development a construction of critical components for the deep undersea neutrino detector facility. We have designed and developed the acoustical positioning system required to permit reconstruction of muon tracks with sufficient precision to meet the astrophysical goals of the experiment. In addition, we are making significant contributions to the design of the database and triggering system to be used. Work has been continuing in other aspects of the study of multiparticle production processes in nuclei. We are participants in a joint US/Japan program to study nuclear interactions at energies two orders of magnitude greater than those of existing accelerators, using balloon-borne emulsion chambers. On one of the flights we found two nuclear interactions of multiplicity over 1000 -- one with a multiplicity of over 2000 and pseudorapidity density {approximately} 800 in the …

The objective of this study is to develop technology that permits the practical and economic preparation, storage, handling, and transportation of coal pellets, which can be reslurried into Coal water fuels (CWF) suitable for firing in small- and medium-size commercial and industrial boilers, furnaces, and engines. The project includes preparing coal pellets and capsules from wet filter cake that can be economically stored, handled, transported, and reslurried into a CWF that can be suitably atomized and fired at the user site. The wet cakes studied were prepared from ultra-fine (95% -325 mesh) coal beneficiated by advanced froth-flotation techniques. The coals studied included two eastern bituminous coals, one from Virginia (Elkhorn) and one from Illinois (Illinois No. 6) and one western bituminous coal from Utah (Sky Line coal).

Calculations have been performed to determine the reactivity worth of various partial rod movements to be performed in the K-14 Startup and Power Ascension Test Program. Some tests have been revised since the issuance of the predictions and acceptance criteria for the startup/power ascension testing procedure, RSP 90-007. The tests were modified to account for changes in the Technical Specifications concerning control rod positioning. This addendum describes the changes to the test configurations and documents the revised expectation values for the partial rod insertion tests. Additional calculations were performed to cover the complete range of possible full rod positions at the zero power testing level.

This QA Plan identifies the activities and responsibilities which are necessary in the design, procurement, fabrication, installation, and start …

The reactions of OH radicals with hydrocarbons have received a great deal of attention in recent years because of these processes are principal steps in the oxidation of organic fuels -- whether occurring in combustion/propulsion systems, in the atmosphere, or elsewhere. Of the various radicals capable of attacking hydrocarbons, OH radicals are generally the most reactive, and their reactions directly yield water molecules, one of the major final oxidation products. In the atmosphere, the combined effect of the OH radical's reactivity and concentration make it the single species that determines the atmospheric lifetime of an organic substance. The principal goals of the kineticist in the field of oxidation chemistry are (1) to measure as many elementary reaction rate coefficients as are conveniently studied in the laboratory; and (2) to develop theoretical and/or semiempirical tools for extrapolating from measured rate coefficients to unmeasured ones. The latter step is necessary because of the sheer number of reactions of possible interest.
