The primary concern of the study during this period has been to examine the origin and basis of the several nonconforming NMR lines reported in our earlier study. Previous studies by earlier investigators indicate that (a) the product distribution in the conversion of synthesis gas to liquid fuels is dependant on the copper/cobalt ratio and (b) that the catalytic results reported by different groups of investigators using the IFP prescription (4) are widely divergent. These observations prompted us to make a critical examination of the effect of metal ratio and the method of preparation on the magnetic character of catalysts.

The Department of Energy (DOE) Environment, Safety and Health Compliance Assessment (Tiger Team) of the Savannah River Site (SRS) questioned the method by which wind speed sensors (cup anemometers) are calibrated by the Environmental Technology Section (ETS). The Tiger Team member was concerned that calibration data was generated by running the wind tunnel to only 26 miles per hour (mph) when speeds exceeding 50 mph are readily obtainable. A wind tunnel experiment was conducted and confirmed the validity of the practice. Wind speeds common to SRS (6 mph) were predicted more accurately by 0--25 mph regression equations than 0--50 mph regression equations. Higher wind speeds were slightly overpredicted by the 0--25 mph regression equations when compared to 0--50 mph regression equations. However, the greater benefit of more accurate lower wind speed predictions accuracy outweight the benefit of slightly better high (extreme) wind speed predictions. Therefore, it is concluded that 0--25 mph regression equations should continue to be utilized by ETS at SRS. During the Department of Energy Tiger Team audit, concerns were raised about the calibration of SRS cup anemometers. Wind speed is measured by ETS with Teledyne Geotech model 1564B cup anemometers, which are calibrated in the ETS wind …

APTBLIBE is a new BUILD library of about 151 Cray-compiled binary subroutines for numerical geometry and Monte Carlo sampling, of which 93 are described here (the rest will be described in a revision). It is designed especially to support 2-D and 3-D codes that generate and track beams or particles of energy or matter (APT = All-Particle-Tracking). The LIB library APTSLIBE contains the FORTRAN source files, and the user document APTDOC, much of which can be updated directly from the source files. This document describes APTBLIBE and its subroutines, how to use them, and the features designed to simplify the development of new codes, and improve the speed, efficiency, reliability and ease of maintenance of any codes which make use of it.

The Energy Information Administration (EIA) is developing the National Energy Modeling System (NEMS) to enhance its energy forecasting capabilities and to provide the Department of Energy with a comprehensive framework for analyzing alternative energy` futures. NEMS is designed with a multi-level modular structure that represents specific energy supply activities, conversion processes, and demand sectors as a series of self-contained units which are linked by an integrating mechanism. The NEMS International Energy Module (IEM) computes world oil prices and the resulting patterns of international trade in crude oil and refined products. This report is a reference document for energy analysts, model users, and the public that is intended to meet EIA`s legal obligation to provide adequate documentation for all statistical and forecast reports (Public Law 93-275, section 57(b)(1). Its purpose is to describe the structure of the IEM. Actual operation of the model is not discussed here. The report contains four sections summarizing the overall structure of the IEM and its interface with other NEMS modules, mathematical specifications of behavioral relationships, and data sources and estimation methods. Following a general description of the function and rationale of its key components, system and equation level information sufficient to permit independent evaluation of …

Locked mode coils for detecting radial magnetic field perturbations B{sub r} were recently constructed and installed on the TEXT-U tokamak. The measured experimental signals showed that both minor and major disruptive instabilities were almost always preceded by a growth in B{sub r}. For some plasma discharges with long duration precursors, a mode lock occurs before the disruption takes place. However, detailed investigation showed that the modes were still rotating in the toroidal direction but with a very low frequency of about 50 Hz. The results of the analysis done confirmed that the m=1/m=2 mode coupling is the main triggering mechanism for the disruptions. Only after the coupling has taken place, when the frequency of the MHD activity measured with Mirnov coils has dropped from about 10 kHz to near 5 kHz and the characteristic deformation of the sawteeth has occurred, are fluctuating radial magnetic fields picked up by the locked mode coils.

The Hanford Nuclear Reservation Tank Farms` underground waste tanks have been used to store liquid radioactive waste from defense materials production since the 1940`s. Waste in certain of the tanks may contain material in the form of ferrocyanide or various organic compounds which could potentially be susceptible to condensed phase chemical reactions. Because of the presence of oxidizing materials (nitrate compounds) and heat sources (radioactive decay and chemical reactions), the ferrocyanide or organic material could potentially fuel a propagating exothermic reaction with undesirable consequences. Analysis and experiments indicate that the reaction propagation and/or initiation may be prevented by the presence of sufficient moisture in the waste. Because the reaction would probably be initiated at the surface of the waste, evidence of sufficient moisture concentration would help provide evidence that the tank waste can continue to be safely stored. The Surface Moisture Measurement System (SMMS) was developed to collect data on the surface moisture in the waste by inserting two types of probes (singly) into a waste tank-a neutron probe and an electromagnetic inductance (EMI) probe. The sensor probes will be placed on the surface of the waste utilizing a moveable deployment arm to lower them through an available riser. The …

The overall goal of the Ames Laboratory Expedited Site Characterization (ESC) project is to evaluate and promote both innovative and state-of-the-practice site characterization and/or monitoring technologies. This will be accomplished by fielding both types of technologies together in the context of an expedited site characterization. The first site will be at a former manufactured gas plant (FMGP) in Marshalltown, Iowa. The project will field three areas of technology: geophysical, analytical, and data fusion. Geophysical technologies are designed to understand the subsurface geology to help predict fate and transport of the target contaminants. Analytical technologies/methods are designed to detect and quantify the target contaminants. Data fusion technology consists of software systems designed to rapidly integrate or fuse all site information into a conceptual site model that then becomes the decision making tool for the site team to plan subsequent sampling activity. Not all of the contaminants present can be located at the action level. Polynuclear aromatic hydrocarbons (PAHs) are the signature organics associated with the coal tar activities that took place at the site. As a result, PAHs were selected as the target compounds. Screening analytical instruments and nonintrusive geophysical techniques will be fielded to qualitatively map the spatial contaminant distribution. …

This is an Environmental Assessment (Assessment) (DOE/EA-0935) evaluating the Power Marketing Policy and Subsequent Contracts between Southeastern and its customers. The Assessment evaluates two alternatives and the no action alternative. The proposed action is to market the power and energy available in the Georgia-Alabama-South Carolina System during the next ten years, with new power sales contracts of ten-year durations, to the customers set forth in Appendix A of the Assessment. In addition to the proposed alternative, the Assessment evaluates the alternative of extending existing contracts under the current marketing policy.

Calculations were done to determine a recommended size for the liquid helium storage dewar, gas helium storage tanks, and liquid nitrogen dewar requirements. I recommend a Liquid helium storage dewar with a nominal size of at least 2500 liters (660 gallons), preferably 3000 liters (792 gallons). I recommend obtaining gas helium storage tanks with a maximum allowable working pressure (MA WP) of 250 psig or greater. Combined volume to be at least 5880 cubic feet (44,000 gallons). I recommend obtaining a second liquid nitrogen dewar at D-Zero, dedicated to the refrigerator, solenoid and VLPC systems. The ideal dewar would have a volume of around 16,000 gallons. It's MAWP needs to be greater than 55 psig.

The main emphasis of the proposal had been to study control systems for which the observation function is perspective. Since a CCD camera observes points upto a perspective projection, it is hoped that these dynamical systems would be useful in the study of visually guided control systems: systems for which the feedback control is to be generated with the aid of a CCD camera. We basically divided our task into three distinct subproblems. (1) To define a perspective dynamical system and study problems in this context that arises as a result of state observability, parameter identifiability and controllability. We also proposed to look into the prospect of applying dynamic observers for on line parameter estimation. (2) To apply the proposed perspective theory in the context of controlling a robot arm. The robot is proposed to be controlled with the aid of a pair of CCD cameras for the purpose of dynamic obstacle avoidance and manipulation. (3) The theory and application of a perspective dynamical system in the context of controlling a robot manipulator is to be extended to a general context wherein a visual cognition framework involves image understanding using multiresolution analysis and various other biologically plausible framework and the …

The objectives of this project are to test novel fullerene based catalysts for application in methane activation. During this period we investigated a novel method of activating carbon soot which was recently reported in literature. In this method, the soot is treated with carbon dioxide at temperatures of 850{degrees}C to give a microporous carbon with a high surface area. We repeated this activation step and found that the BET surface areas increased from approximately 125 m{sup 2}/g to over 600 m{sup 2}/g. We plan to test this activated soot for methane activation to compare with the results obtained before activation. We continued our investigation of the base-line conditions for both thermal reactions and soot-catalyzed reactions of methane, and in addition, we compared these results to those obtained with Norit-A carbon as a catalyst. Diluents such as hydrogen and helium were added into the reaction system to determine their respective effects on selectivity during the methane activation experiments. In terms of methane activation, under our conditions, the fullerene soot was found to be the most active, with the threshold for the methane activation below as 800{degrees}C, while the Norit-A catalyst exhibited a threshold slightly above 800{degrees}C, and the pure thermal reaction …

The One-Angstrom Microscope project has attained its goal, and is now producing images down to 1 Angstrom resolution. We have demonstrated transmission electron microscopy of defect structures down to a resolution of 1.1 Angstrom, with evidence that 0.89 Angstrom will be possible. This level of resolution will soon be made available to all those NCEM users who have a requirement for sub-Angstrom resolution.

New data on tank 241-C-106 were obtained from grab sampling and from compatibility testing of tank C-106 and tank AY-102 wastes. All chemistry-associated and other compatibility Information compiled in this report strongly suggests that the sluicing of the contents of tank C-106, in accord with appropriate controls, will pose no unacceptable risk to workers, public safety, or the environment. In addition, it is expected that the sluicing operation will successfully resolve the High-Heat Safety Issue for tank C-106.

This document summarizes the information on the historical uses, present status, and the sampling and analysis results of waste stored in Tank 241-BX-103. This report supports the requirements of Tri- Party Agreement Milestone M-44-09.
