Survey of gas quality results from three gas-well-stimulation experiments by nuclear explosions
Gas quality results obtained at LLL on samples taken from the three nuclear gas-well-stimulation experiments (Gasbuggy, Rulison, Rio Blanco) are used to illustrate the differences and similarities of the three projects. All of the gas analysis data shown here have been previously published in LLL reports, but heretofore, intercomparisons have been difficult because of the different formats used in the various publications. Also, the data from the three expriments have not previously been manipulated in the same way so that postshot conditions in the three cavity and chimney systems could be compared. As the pressure and temperature increase in the cavity and chimney system (as they do with increasing depth of burial) the amount of water produced with the chimney gas increases markedly. Differences in late-time additions of CO/sub 2/ to the chimney gas were also observed. Previously reported radiological safety studies of the potential effects from the use of nuclearly stimulated gas are discussed, and the required steps that could lead to the possible sale of nuclearly stimulated gas to the general public are listed.

Progress in Diamond Cell Experiments: Pressures Above Three Megabars
Diamond cell experiments at pressures above 2 megabars have many important applications with respect to planetary interiors (e.g., metallization of hydrogen). To make possible acquisition of data at extreme pressures on materials of planetary interest, we have been exploring both numerically and experimentally several aspects of diamond cell design and methodology. We have conducted detailed finite element analyses of the diamond cell to explore how bevelled anvils and material properties of the gasket affect diamond cell performance (1). These calculations include nonlinear equations of state, gasket plasticity, and diamond-gasket interfacial friction. Gasket plasticity has a dramatic effect on the stress field and thus must be included in any physically realistic analysis of the diamond cell; purely elastic calculations, therefore, cannot model adequately the behavior of a diamond cell. Gasket yield strengh is very important in facilitating generation of extreme pressures in a diamond cell. Increasing gasket yield strength allows a higher radial pressure gradient to be supported at a given gasket thickness, which means that failure of an experiment by deformation of the anvils to allow anvil-anvil contact occurs at higher pressures than would occur with a lower yield strength gasket. Furthermore, the finite element analyses indicate that increasing gasket …

Fatigue-crack propagation response of two nickel-base alloys in a liquid sodium environment
The elevated temperature fatigue-crack propagation response of Inconel 600 and Inconel 718 was characterized within a linear-elastic fracture mechanics framework in air and low-oxygen liquid sodium environments. The crack growth rates of both nickel-base alloys tested in liquid sodium were found to be considerably lower than those obtained in air. This enhanced fatigue resistance in sodium was attributed to the very low oxygen content in the inert sodium environment. Electron fractographic examination of the Inconel 600 and Inconel 718 fatigue fracture surfaces revealed that operative crack growth mechanisms were dependent on the prevailing stress intensity level. Under low growth rate conditions, Inconel 600 and Inconel 718 fracture surfaces exhibited a faceted, crystallographic morphology in both air and sodium environments. In the higher growth rate regime, fatigue striations were observed; however, striations formed in sodium were rather ill-defined. These indistinct striations were attributed to the absence of oxygen in the liquid sodium environment. Striation spacing measurements were found to be in excellent agreement with macroscopic growth rates in both environments.

Perceived and calculated health risks: do the impacts differ
In many cases of radioactive and hazardous waste management, some members of the general public perceive that human health risks associated with the wastes are higher than the calculated risks. Calculated risks are projections that have been derived from models, and it is these risks that are usually used as the basis for waste management. However, for various reasons, the calculated risks are often considered by the public as too low or inappropriate. The reasons that calculated risks are not perceived as accurate and the factors that affect these perceptions are explored in this paper. Also discussed are the impacts related to the perceived and calculated health risks: what they are, and if and how they differ. The kinds of potential impacts examined are health effects, land value changes, and social, transportation, and economic effects. The paper concludes with a discussion of the implications of incorporating these different risk perspectives in decisions on waste management.

Fundamental mechanisms in flue gas conditioning
This project is divided into four tasks. Task 1 is the Development of a Management Plan. Task 2, Evaluation of Mechanisms in FGD Sorbent and Ash Interactions, focuses on the characteristics of binary mixtures of these distinct powders. Task 3, Evaluation of Mechanisms in Conditioning Agents and Ash, is designed to examine the effects of various conditioning agents on fine ash particles to determine the mechanisms by which these agents alter the physical properties of the ash. Tasks 2 and 3 began with an extensive literature search and the assembly of existing theories. The results of the work performed under Tasks 2 and 3 will be included in a Flue Gas Conditioning Model that will be issued under Task 4. The Final Report for the project will also be prepared under Task 4. This quarterly report covers four months in order to synchronize the reporting periods for this project with US Government quarters. Work performed on the project during the past quarter consisted almost entirely of the review of literature pertaining to the objectives of Tasks 2 and 3. The primary results of that review are discussed at length in Topical Reports 1 and 2, submitted January 9, 1992. As …

Design and test of an exhaust-gas clean-up system for powerplants using high-sulphur-content fuels
The progress to date for each major element of the program is graphed. A description of each program element is given. Completion of the data acquisition system has slipped due to a delay in delivery from Hewlett Packard. Part of the labor costs allocated for this includes time for personnel to become familiar with the equipment and to integrate the system with the test set-up. Completion of the test cell and the fuel system has slipped. This has turned out to be a significant undertaking and is being paced by the three contractors supplying the plumbing, air conditioning and fuel tank. Completion of each is now scheduled for March 1, and no slippage in the completion of the exhaust gas simulator is anticipated. The other element underway is a pilot model of the two-stage deaeration system. This work is briefly described.

Development of biological coal gasification (MicGAS process)
Effect of 5% and 10% coal solids loadings was studied in two types of bench scale bioreactors and in chemostat cultures. The bench scale reactors used were rotating biological contactor (RBC) and upflow bioreactors. In RBC, Texas lignite was loaded at 0% and 5% (w/v), while in the upflow and chemostat reactors at 0%, 5% and 10%. Methane, total gas production, soluble carbon and volatile fatty acid production (VFA), as well as microbial growth (measured as cell protein) were monitored. Gas analysis of the headspace from the above mentioned reactors showed higher CO[sub 2] production in experiments with 5% and 10% coal solids (for example, Figure 1). This indicates that acetate degraded into CO[sub 2] but there was not enough hydrogen to carry out the reaction to convert CO[sub 2] to CH[sub 4]. These data obtained confirmed our previous results from laboratory scale reactors, that at coal solids loadings higher than 1%, methane production does not enhance significantly. This phenomena could be due to the production of higher quantities of inhibitory compounds or depletion of factors necessary for methanogenesis.
