Confinement and stability of a Crystalline Beam
This technical report defines and describes a Crystalline Beam. This is an ordered state of matter made of electrically charged ions which are moving together in a storage ring with very high density and small velocity spread. In particular, the paper analyses the requirements for the confinement and the stability of the Beam. It is demonstrated that a storage ring made of one circular weak-focusing magnet, similar to a Betatron, is the most suitable for the confinement and stability of the Crystalline Beam. The disruptive effects of drift insertions have also been investigated. Requirements on final densities and velocity spreads are also calculated and reported. A matrix formalism is developed for the design of the storage ring. The important issue of the disruption caused by the curvature of the closed trajectory is not here discussed; it is the subject of a subsequent paper.

Steam gasification of carbon: Catalyst properties
Coal gasification by steam is of critical importance in converting coal to gaseous products (CO, H[sub 2], CO[sub 2], CH[sub 4]) that can then be further converted to synthetic natural gas and higher hydrocarbon fuels. Alkali and alkaline earth metals (present as oxides) catalyze coal gasification reactions and cause them to occur at significantly lower temperatures. A more fundamental understanding of the mechanism of the steam gasification reaction and catalyst utilization may well lead to better production techniques, increased gasification rates, greater yields, and less waste. We are studying the gasification of carbon by steam in the presence of alkali and alkaline earth oxides, using carbonates as the starting materials. Carbon dioxide gasification (CO[sub 2] + C --> 2CO) has been studied in some detail recently, but much less has been done on the actual steam gasification reaction, which is the main thrust of our work. In particular, the form of the active catalyst compound during reaction is still questioned and the dependence of the concentration of active sites on reaction parameters is not known. Until recently, no measurements of active site concentrations during reaction had been made. We have recently used transient isotope tracing to determine active site concentration …

Applications of Micellar Enzymology to Clean Coal Technology
The sequential addition of enzyme and H[sub 2]O[sub 2] during the reverse micelle incubation was found to enhance sulfoxidation, but levels of EPSn remained low. The triplicate addition of enzyme and H[sub 2]0[sub 2] during the reverse micelle incubation of EPS was found to enhance sulfoxidation to EPSn and unidentified material. Low conversion to EPSn was not due to the inability of the enzyme to oxidize EPSX in reverse micelles, since the latter was demonstrated with both commercially available and enzymatically synthesized EPSx as starting material. Chloroperoxidase in an AOT-isooctane reverse micelle solution also mediated production of a metabolite from DBT with characteristics consistent with DBTSx. The magnitude of conversion was enhanced to 10% of the starting material by triplicate addition of enyme and H[sub 2]0[sub 2]. The identity of this metabolite as DBTSx was verified by GC/MS. Chloroperoxidase in reverse micelles appears therefore to be a versatile catalyst for sulfoxidation of aliphatic and aromatic sulfur-containing model coal compounds.

Industrial pulverized coal low NO[sub x] burner
The objective of Phase 1 of the Industrial Pulverized Coal Low NO[sub x] Burner'' Program is to develop a novel low NO[sub x], pulverized coal burner, which offers near-term commercialization potential, uses preheated combustion air of up to 1000[degrees]F, and which can be applied to high-temperature industrial heating furnaces, chemical process furnaces, fired heaters, and boilers. The program team is led byArthur D. Little, Inc., and includes the Massachusetts Institute of Technology (MIT) and Hauck Manufacturing Company. During the first quarter of the program the program team developed the overall program management plan; began a market survey to identify coals suitable for modeling the low NO[sub x], burner design and performance, as well as for use in the Phase II burner tests; and defined the preliminary burner design specifications, sized the prototype burner, and produced the first concept schematic. This report is for the second quarter of the program (July 1992 to September 1992). During this period the program team: Completed the study of industrial coal usage and sources; refined the preliminary burner design and confirmed it as the basis for computer modeling; and started definition of the modeling work scope, including the development of fuel and process specifications, description …

Program plan, and request for reprogramming first year funds
In June of 1992, the U. S. Department of Energy (DOE) awarded assistance Medical University of South Carolina (MUSC) for the Environmental Hazards Assessment Program, The first year of the program is primarily a planning year. We have aggressively pursued input into the EHAP program to begin to understand where our efforts fit within other efforts underway nationally. We have also begun some direct activities at MUSC to begin the program. Part of this report is devoted to informing DOE of what we have accomplished so far this year. In our efforts to plan, we have identified several changes in emphasis for the program. These changes affect the original plan in terms of projected milestones and budget allocations. Part of this report describes these changes and describes the proposed changes to the budget. We are not requesting additional funds for this year. Simply, we are requesting some change in allocations to budget categories. Therefore, our report to DOE is a combination status report, program plan, and request for reallocation of budget.

Biological Conversion of Synthesis Gas
A continuous stirred tank reactor with and without sulfur recovery has been operated using Chlorobium thiosulfatophilum for the conversion of H[sub 2]S to elemental sulfur. In operating the reactor system with sulfur recovery, a gas retention time of 40 min was required to obtain a 100 percent conversion of H[sub 2]S to elemental sulfur. Essentially no SO[sub 4][sup 2[minus]], an undesirable product, was produced under these conditions. Significant reductions in the gas retention time are expected by employing cell recycle after sulfur recovery, and by using increased pressure.

A global overview of risk management of the DOE complex
No endeavor is risk-fire and as we realize the inherent risks in society, our only viable solution is to manage the risk. Application of an integrated risk management program of a large technological system like the DOE complex is a difficult, task; but it is the only rational means to optimize the risk-benefit equation. An effective risk management culture-within the DOE complex will in the long run, ensure a consistent response to mitigate identified risks. An effective risk management program provides responsible administrative planning and logical application of the best technical analyses. It requires the involvement of all personnel. Our objective in this paper is to point out broad perspectives that raise concerns about future DOE ask management issues and to suggest some possible remedies.
