This talk deals with {Lambda}, K{sub s}{sup 0} and {bar {Lambda}} production with 14.5 GeV/c Silicon beams. Why study {Lambda}{sup 0} production Because the study of strangeness is an important part of the search for Quark Gluon Plasma (QGP). Many models predict an enhancement of strangeness in a QGP as compared to the amount of strangeness produced in a superposition of nucleon-nucleon interactions. The amount of enhancement varies from model to model. Even if no QGP is detected at AGS energies using Si beams, it is important to understand the production mechanisms in quantitative detail so that standard nucleon-nucleon production mechanism can be distinguished from QGP formation. The advantage of measuring strangeness production by measuring V{sup 0} production is that V{sup 0}'s can be identified by kinematics without the use of any special particle ID detectors. The disadvantage is that usually large aperture detectors are required. Experiment 810 has the needed large aperture. This talk describes the technique and results of V{sup 0} production from {approximately}9000 interactions of Si in a 1 mil (25 micron) Au target recorded in June 1989. 13 figs., 1 tab.

Cooling water for L and K Reactors and makeup water for Par Pond is pumped from the Savannah River at the 1G, 3G, and 5G pump houses. Ichthyoplankton (drifting fish larvae and eggs) from the river are entrained into the reactor cooling systems with the river water and passed through the reactor's heat exchangers where temperatures may reach 70[degrees]C during full power operation. Ichthyoplankton mortality under such conditions is assumed to be 100 percent. The number of ichthyoplankton entrained into the cooling system depends on a variety of variables, including time of year, density and distribution of ichthyoplankton in the river, discharge levels in the river, and the volume of water withdrawn by the pumps. Entrainment at the 1 G pump house, which is immediately downstream from the confluence of Upper Three Runs Creek and the Savannah River, is also influenced by discharge rates and ichthyoplankton densities in Upper Three Runs Creek. Because of the anticipated restart of several SRS reactors and the growing concern surrounding striped bass and American shad stocks in the Savannah River, the Department of Energy requested that the Environmental Sciences Section (ESS) of the Savannah River Laboratory sample ichthyoplankton at the SRS Savannah River intakes. …

This research project involves the study of coal macerals and sorbent microparticles used to remove S0{sub 2} and/or H{sub 2}S from process streams. To measure reaction rates a charged single microparticle will be held electrodynamically in one or more laser beams by superposed ac and dc electrical fields. The use of the electrodynamic balance for microparticle studies was pioneered by one of the principal investigators. One of the laser beams is used for light-scattering measurements to determine the particle size and to provide the excitation source for obtaining Raman spectra to chemically characterize the particle. The other beam, an infrared beam, is used to heat the particle electromagnetically. The first year of the research was devoted to preliminary experimental work and design studies. Although components and techniques must still be developed, experimental measurements on single macerals are now being done.

A theory was developed for the fraction of near-surface air likely to form forced and active cumulus clouds. This stochastic method is based on a 2-D frequency distribution of the occurrence of various buoyancy and condensation levels in air near the surface, and the relationship of this distribution to the mean temperature profile. An alternative form of this theory utilizes a 2-D distribution of convective available potential energies (CAPE) instead of virtual potential temperatures.

The Oak Ridge K-25 Technology Logic Diagram (TLD), a decision support tool for the K-25 Site, was developed to provide a planning document that relates envirorunental restoration and waste management problems at the Oak Ridge K-25 Site to potential technologies that can remediate these problems. The TLD technique identifies the research necessary to develop these technologies to a state that allows for technology transfer and application to waste management, remedial action, and decontamination and decommissioning activities. The TLD consists of four separate volumes-Vol. 1, Vol. 2, Vol. 3A, and Vol. 3B. Volume 1 provides introductory and overview information about the TLD. This volume, Volume 2, contains logic diagrams with an index. Volume 3 has been divided into two separate volumes to facilitate handling and use.

Experiments were performed to understand laser-induced back-ablation of Al film targets with picosecond laser pulses. Al films deposited on the back surface of BK-7 substrates are ablated by picosecond laser pulses propagating into the Al film through the substrate. The ablated Al plume is transversely probed by a time-delayed, two-color sub-picoseond (500 fs) pulse, and this probe is then used to produce self-referencing interferograms and shadowgraphs of the Al plume in flight. Optical emission from the Al target due to LIBA is directed into a time-integrated grating spectrometer, and a time-integrating CCD camera records images of the Al plume emission. Ablated Al plumes are also redeposited on to receiving substrates. A post-experimental study of the Al target and recollected deposit characteristics was also done using optical microscopy, interferometry, and profilometry. In this high laser intensity regime, laser-induced substrate ionization and damage strongly limits transmitted laser fluence through the substrate above a threshold fluence. The threshold fluence for this ionization-based transmission limit in the substrate is dependent on the duration of the incident pulse. The substrate ionization can be used as a dynamic control of both transmitted spatial pulse profile and ablated Al plume shape. The efficiency of laser energy transfer …

The Petroleum Supply Monthly (PSM) is one of a family of three publications produced by the Petroleum Supply Division within the Energy Information Administration (EIA) reflecting different levels of data timeliness and completeness. The other two publications are the Weekly Petroleum Status Report (WPSR) and the Petroleum Supply Annual (PSA). Data presented in the Petroleum Supply Monthly describe (PSM) the supply and disposition of petroleum products in the United States and major US geographic regions. The data series describe production, imports and exports, inter-Petroleum Administration for Defense (PAD) District movements, and inventories by the primary suppliers of petroleum products in the United States (50 States and the District of Columbia). The reporting universe includes those petroleum sectors in Primary Supply.'' Included are: petroleum refiners, motor gasoline blenders, operators of natural gas processing plants and fractionators, inter-PAD transporters, importers, and major inventory holders of petroleum products and crude oil. When aggregated, the data reported by these sectors approximately represent the consumption of petroleum products in the United States. Data presented in the PSM are divided into two sections: (1) the Summary Statistics and (2) the Detailed Statistics.

From our work with baseline ceramics containing Pu, or Ce substituted for Pu, doped with sets of inactive impurity ions (with supposedly the same valency) and sintered in different atmospheres, the conclusion is that all ions of similar size and valency are indeed crystal-chemically equivalent unless there are volatility problems. However, the real question appears to be what are the appropriate valency states of the multivalent impurity ions under given sintering conditions. For example, when sintered in highly reducing atmospheres (in this case 3.7 % hydrogen in argon) Mo, W, Zn, Fe, Cu, Co and Ni are reduced to metal. The partitioning across the different phases present is apparently not even. The elements from the nominal 2+, 3+, 4+, 5+ and 6+ families will preferentially move to certain phases or result in the formation of new phases if sufficient amounts are present. If the phases of the baseline ceramic (pyrochlore-zirconolite, brannerite and rutile) are saturated with these ions, new phases will form to take up the excess impurity ions. Additional such phases detected in this work included ulvospinel, perovskite, magnetoplumbite, loveringite-like phases, metallic alloys and powellite/scheelite. The Pu and Ce-doped samples give similar results to each other. While samples sintered …

Research in this project centers upon developing a new approach to the direct liquefaction of coal to produce an all-distillate product slate at a sizable cost reduction over current technology. The approach integrates all aspects of the coal liquefaction process including coal selection, pretreatment, coal swelling with catalyst impregnation, coal liquefaction experimentation, product recovery with characterization, alternate bottoms processing, and a technical assessment including an economic evaluation. The project is being carried out under contract to the United States Department of Energy. On May 28, 1992, the Department of Energy authorized starting the experimental aspects of this projects; therefore, experimentation at Amoco started late in this quarterly report period. Research contracts with Auburn University, Pennsylvania State University, and Foster Wheeler Development Corporation were signed during June, 1992, so their work was just getting underway. Their work will be summarized in future quarterly reports. A set of coal samples were sent to Hazen Research for beneficiation. The samples were received and have been analyzed. The literature search covering coal swelling has been up-dated, and preliminary coal swelling experiments were carried out. Further swelling experimentation is underway. An up-date of the literature on the liquefaction of coal using dispersed catalysts is nearing …

We present results from a four-port Michelson interferometer built to demonstrate imaging Fourier transform spectroscopy for astronomical applications.

The purpose of the Tanks Focus Area (TFA) Midyear Review was to improve the quality and responsiveness of TFA technical solutions to identified user needs. This review goal was achieved through executing a multi-phased review approach. The first phase of the midyear review focused on the subset of FY99 work identified by Department of energy users as having continuing benefit in FY00-01. The TFA FY00-02 Technical Responses identified FY99 work that had continued applicability based on the most current set of site user needs. Each TFA FY00-02 Technical Response which included FY work scope was reviewed by the TFA Technical Advisory Group (TAG), in a meeting held in February 1999. Made up of technical experts from across the country, the TAG provides high-quality, short-turnaround, independent technical reviews for the TFA.

The preparation of binderless iron oxide spheres has been achieved by a novel sol-gel forming procedure. The starting material is a solution of iron (III) 2-ethylhexanoate in mineral spirits. This solution is added dropwise to an ammoniacal solution of methanol. The low viscosity of the methanol causes the formation of small droplets of the iron solution. The immiscibility of the mineral spirit solution in the methanol and the difference in surface tensions cause the droplets to assume a spherical shape. The presence of ammonia and water at low levels in the methanol promotes the hydrolysis of the iron (III) 2-ethylhexanoate, which causes the spherical particles to harden. The iron-containing spheres can then be isolated by filtration. These spheres are the first ones reported to be made of 100% iron oxide and prepared without a binder. In the initial preparations, the spheres are 100 to 200{mu}m in diameter. Some problems remain to be resolved with this new method of preparation.

In FY92, the ALT-II program is concentrating on three main physics areas: pumped limiter experiments, which include He exhaust and high density high power operation; limiter bias experiments focused on modifying edge transport and particle removal; and and edge transport and flow studies, which examine the equilibrium edge flows and transport physics during Ohmic, L-mode, Supershot, and H-mode confinement regimes. In support of these physics objectives, a CCD diagnostic system has been delivered to TEXTOR and is being used to supplement the previous ALT-II diagnostic system. A second fast-scanning Langmuir probe was constructed at UCLA and has been delivered to TEXTOR for use in studies of edge plasma flows, turbulent transport, and poloidal asymmetries. A brief synopsis of each topic is given below. Work will continue on these physics topics during the balance of FY92.

An automated method is described for binding attributes to extracted data from a telemetry steam. These attributes can be used by post processing utilities to facilitate efficient analysis. A practical implementation of such a scheme is described.

The Supplemental Design Requirements Document (SDRD) is used to communicate plant design information from Westinghouse Hanford Company (WHC) to the US Department of Energy (DOE) and the cognizant Architect Engineer (A/E). Information in the SDRD serves two purposes: to convey design requirements that are too detailed for inclusion in a Functional Design Criteria (FDC) report; and to serve as a means of change control for design commitments in the Conceptual Design Report. The mission of WRAP 2A on the Hanford site is the treatment of contact handled low level mixed waste (MW) for final disposal. The overall systems engineering steps used to reach construction and operation of WRAP 2A are depicted in Figure 1. The WRAP 2A SDRD focuses on the requirements to address the functional analysis provided in Figure 1. This information is provided in sections 2 through 5 of this SDRD. The mission analysis and functional analysis are to be provided in a separate supporting document. The organization of sections 2 through 5 corresponds to the requirements identified in the WRAP 2A functional analysis.

This is an evaluation of the Crude Oil Policy Model (COPM) and the assumptions driving the estimates of future crude oil production and abandonments attributable to an accelerated federal oil R&D program which were cited in the National Energy Strategy. This evaluation focuses on the logic and inputs to the model itself, and their impact on the NES estimates. A plan for making the recommended enhancements is also discussed. A parallel effort is also now in progress to make a number of model enhancements that will facilitate the analysis of RCRA impacts. This effort is scheduled to be completed for the Office of Planning and Environment in mid-August. A description of these enhancements is also included in our plan for correcting and enhancing the COPM.
