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.

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.

ANORM is a reliable, portable Fortran function program, written in the style of the SPECFUN package for computing the normal probability distribution to full machine precision on most contemporary computers. The main computation evaluates near-minimax approximations that are theoretically accurate to at least 18 significant decimal digitals. Special care has been taken in implementation to minimize error contamination in the crucial computations of the exponential and to provide full accuracy in the computation with large negative arguments. ANORM returns 0.0 for arguments smaller than the machine-dependent constant XLOW and returns 1.0 for arguments greater than the machine-dependent constant XUPPR.

The Los Alamos National Laboratory (LANL) generates transuranic (TRU) waste in a variety of programs related to national defense. TRU waste is a specific class of radioactive waste requiring permanent isolation. Most defense-related TRU waste will be permanently disposed of in the Waste Isolation Pilot Plant (WIPP). WIPP is a deep geologic repository located in southeastern New Mexico and is now in the testing phase of development. All waste received by Wipp must conform with established Waste Acceptance Criteria (WAC). The purpose of the proposed action is to retrieve stored TRU waste and prepare the waste for shipment to and disposal WIPP. Stored TRU waste LANL is represented by four waste forms. The facilities necessary for work-off activities are tailored to the treatment and preparation of these four waste forms. Preparation activities for newly generated TRU waste are also covered by this action.

During its nine day existence, Hurricane Hugo tracked thousands of miles, caused millions of dollars in property damage, and took many lives. Puerto Rico, Guadeloupe, the Virgin Islands, and South Carolina took the brunt of the storm. The staff of meteorologists of the Environmental Technology Section (ETS) provided briefings and forecasts to assist Savannah River Site management in developing appropriate site-wide protective action plans. ``Loops`` created from infrared satellite imagery provided the most useful forecasting tool. Single-site, composite radar imagery and wind measurements from the nine 200 m towers provided real-time monitoring of the effects of Hugo at SRS. A peak wind gust of 64.9 mph and up to 5.05 inches of precipitation were recorded at SRS. An assessment of the potential for wind damage to selected SRS facilities, had Hugo passed over SRS, showed that little structural damage would have occurred with proper pre-storm preparation.

An effort to assess the criticality risks of {sup 239}Pu in TRU Burial Ground Culverts has been underway for several years. The concern arose from discrepancies in two types of monitors that have been used to assay the {sup 239}Pu waste prior to storage in 55-gallon drums that are placed in the culverts. One type is the solid waste monitor (SWM), which is based on gamma-ray measurements; the other is the neutron coincidence monitor, which is based on neutron measurements. The NCC was put into routine service after 1985 and has generally yielded higher 239 Pu assays than the SWM. Culverts with pre-1986 waste only had SWM assays of {sup 239}Pu; thus, it was questioned whether their actual {sup 239}Pu loadings could be high enough to pose criticality concerns. Studies to characterize the culvert criticality potential have included appraisal of NCC vs SWM, neutron measurements atop the culverts, gamma-ray measurements atop the culverts, and probabilistic risk analyses. Overall, these studies have implied that the culverts are critically safe; however, their results have not been examined collectively. The present report uses the collective information of the preceding studies to arrive at a more complete assessment of the culvert criticality aspects. A …

This project is designed to develop methods for pre-combustion 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 Dibenzothiophene (DBT) and ethlyphenylsulfide (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. Among the variables which will be examined are the surfactant, the solvent, the water:surfactant ration and the pH and ionic strength of the aqueous phase. Studies were carried out with HRP, Type I RZ=1.2 and Type VI RZ=3.2 and laccase from Polyporus versicolor. Substrates for HRP assays included hydrogen peroxide, DBT, DBT sulfoxide, and DBT sulfone. Buffers included sodium phosphate. For formation of reverse micelle solutions the surfactant AOT, di(2-ethyl-hexyl)sodium sulphosuccinate, was obtained from Sigma Chemical Co. Isooctant was used as …

Motivated by the recent developments in the cyclotron resonance upscattering of soft photons or CUSP model of Gamma Ray Burst (GRB) continuum spectra, we revisit a select database of GRBs with credible cyclotron absorption features. We measure the break energy of the continuum, the slope below the break and deduce the soft photon energy or the electron beam Lorentz factor cutoff. We study the correlation (or lack of) between various parameters in the context of the CUSP model. One surprise result is that there appears to be marginal correlation between the break energy and the spectral index below the break. 20 refs., 8 figs., 2 tabs.

This analysis report presents the projected requirements for uranium concentrate and uranium enrichment services to fuel the nuclear power plants expected to be operating under three nuclear supply scenarios. Two of these scenarios, the Lower Reference and Upper Reference cases, apply to the United States, Canada, Europe, the Far East, and other countries with free market economies (FME countries). A No New Orders scenario is presented only for the United States. These nuclear supply scenarios are described in Commercial Nuclear Power 1990: Prospects for the United States and the World (DOE/EIA-0438(90)). This report contains an analysis of the sensitivities of the nuclear fuel cycle projections to different levels and types of projected nuclear capacity, different enrichment tails assays, higher and lower capacity factors, changes in nuclear fuel burnup levels, and other exogenous assumptions. The projections for the United States generally extend through the year 2020, and the FME projections, which include the United States, are provided through 2010. The report also presents annual projections of spent nuclear fuel discharges and inventories of spent fuel. Appendix D includes domestic spent fuel projections through the year 2030 for the Lower and Upper Reference cases and through 2040, the last year in which …

A photoacoustic spectrometer, equipped with an 85 meter optical fiber, was used to perform absorption measurements of lanthanide and actinide samples, located in a glovebox. The spectrometer was tested using aqueous solutions of praseodymium and americium ions; the sensitivity for remote measurements was found to be similar to that achieved in the laboratory without the fiber. 14 refs., 3 figs.

Present legislation effectively bans the export of crude oil produced in the United States. The ban has been in effect for years and is particularly stringent with respect to crude oil produced in Alaska, particularly on the North Slope. The Alaska crude export ban is specifically provided for in the Trans-Alaska Pipeline Authorization Act of 1973 and in other legislation. It was imposed for two reasons. The first was to reduce US dependence on imported crude oil. The Arab oil embargo had been imposed shortly before the Act was passed and a greater measure of energy independence was considered imperative at that time. The second reason was to assure that funds expended in building an Alaskan pipeline would benefit domestic users rather than simply employed to facilitate shipments to other countries. The main objective of this report is to estimate the potential impacts on crude oil prices that would result from lifting the export ban Alaskan crude oil. The report focuses on the Japanese market and the US West Coast market. Japan is the principal potential export market for Alaskan crude oil. Exports to that market would also affect the price of Alaskan crude oil as well as crude oil …

The Monthly Energy Review presents current data on production, consumption, stocks, imports, exports, and prices of the principal energy commodities in the United States. Also included are data on international production of crude oil, consumption of petroleum products, petroleum stocks, and production of electricity from nuclear-powered facilities.

The idea of supplementing Level-2 filtering nodes with additional processing power has been alive within D0 collaboration for some time now. The utility of additional processing power became increasingly recognized as the Level-2 filtering code matures. Here we will describe one scenario of augmenting Level-2 nodes with coprocessing power within the framework of the present D0 data acquisition system. Primary data reduction, consisting of repetitive but simple tasks, form the major part of the first order Level-2 filter, in terms of its time budget. Such computing tasks are well suited to the coprocessor environment. In what follows we will use the term Special Function Coprocessor (SFC) to denote this additional processor. 2 figs.

Neutron-rich rare-earth nuclei were produced in multinucleon transfer reactions of {sup 170}Er and {sup 176}Yb projectiles on {sup nat}W targets at the Lawrence Berkeley Laboratory SuperHILAC and their radioactive decays properties studied at the on-line mass separation facility OASIS. Two unknown isotopes, {sup 169}Dy (t {sub 1/2} {equals} 39 {plus minus} 8 s) and {sup 174}Er(t{sub 1/2} {equals} 3.3 {plus minus} 0.2 m) were discovered and their decay characteristics determined. The decay schemes for two previously identified isotopes, {sup 168}Dy (t{sub 1/2} {equals} 8.8 {plus minus} 0.3 m) and {sup 171}Ho (t{sub 1/2} {equals} 55 {plus minus} 3 s), were characterized. Evidence for a new isomer of 3.0 m {sup 168}Ho{sup g}, {sup 168}Ho{sup m} (t{sub 1/2} {equals} 132 {plus minus} 4 s) which decays by isomeric transition (IT) is presented. Beta particle endpoint energies were determined for the decay of {sup 168}Ho{sup g}, {sup 169}Dy, {sup 171}Ho, and {sup 174}Er, the resulting Q{beta}-values are: 2.93 {plus minus} 0.03, 3.2 {plus minus} 0.3, 3.2 {plus minus} 0.6, and 1.8 {plus minus} 0.2 MeV, respectively. These values were compared with values calculated using recent atomic mass formulae. Comparisons of various target/ion source geometries used in the OASIS mass separator facility for …

The traveler presented a paper at the Seventh ASTM-EURATOM Symposium on Reactor Dosimetry and co-chaired an oral session on Computer Codes and Methods. Papers of considerable interest to the NRC Surveillance Dosimetry Program involved statistically based adjustment procedures and uncertainties. The information exchange meetings with Czechoslovakia and Hungary were very enlightening. Lack of large computers have hindered their surveillance program. They depended very highly on information from their measurement programs which were somewhat limited because of the lack of sophisticated electronics. The Nuclear Research Institute at Rez had to rely on expensive mockups of power reactor configurations to test their fluence exposures. Computers, computer codes, and updated nuclear data would advance their technology rapidly, and they were not hesitant to admit this fact. Both eastern-bloc countries said that IBM is providing an IBM 3090 for educational purposes but research and development studies would have very limited access. They were very apologetic that their currencies were not convertible, and any exchange means that they could provide services or pay for US scientists in their respective countries, but funding for their scientists in the United States, or expenses that involved payment in dollars, must come from us.

ESME is a computer program to calculate the evolution of a distribution of particles in energy and azimuth as it is acted upon by the radiofrequency system of a proton synchrotron. It provides for the modeling of multiple rf systems, feedback control, spacecharge, and many of the effects of longitudinal coupling impedance. The capabilities of the program are described, and the requirements for input data are specified in sufficient detail to permit significant calculations by an uninitiated user. The program is currently at version 7.1 and extensively modified since the previous user documentation. Fundamental enhancements make version 6 data unusable, but nearly all facilities of the earlier version have been retained and input data is similar. Also described is a VAX-based code management convention which has been established with a view to maintaining functional equivalence in versions used on different computers. 13 refs.

The tracking detector of AGS Experiment 810 is a three-piece Time Projection Chamber (TPC) intended to measure all charged tracks in the forward hemisphere of the nucleon-nucleon center of mass system, i.e. forward of an angle of about 20 degrees in the lab. Each module of the TPC contains twelve rows of short anode wires which give 3-D space points on each track, but no dE/dx information useable for particle identification. The TPC was operated in a beam of silicon ions at the end of June 1989 and this talk reports the results of analysis of the data taken with a thin gold target in that run. We have gathered a similar amount of data from thin copper and silicon targets, the analysis of which is in a less advanced state. The results of our investigation of the neutral strange particle decays appear in a separate contribution by Al Saulys. This paper presents the current state of the analysis of the charged tracks from the silicon gold collisions. 1 ref., 15 figs.

A preliminary result by the CDF experiment of a reconstructed B meson mass peak from the decays B{sup {plus minus}} {yields} J/{psi}K{sup {plus minus}} and B{sup 0} {yields} J/{psi}K*{sup 0} is also presented. 22 refs., 13 figs.

This study addresses the issue of the ban on exports of Alaskan crude oil. At present almost all crude oil production from Alaska must be sold in the United States, i.e., it may not be exported. This study examines the impact, mainly on the West Coast, of eliminating this export restraint. The study concentrates on two time periods. These are 1988, the most recent year for which complete data are available, and 1995, a year in which Alaskan production is projected to be substantially less than at present. This is the Energy Information Administration's (EIA's) second report on this subject. The first was released earlier in 1990. They differ principally in the years for which results are presented and in the models used to generate quantitative results. The first report was limited to 1988. The quantitative results for that year were based on use of a single region model and therefore did not take into account petroleum interactions among all areas of the world. Because of this limitation, quantitative results were limited to Alaskan crude oil prices. All other price and trade flow results were qualitative. In contrast, the present report covers both 1988 and 1995. The quantitative results are …

The authors are studying aboveground oil shale retorting and have developed the LLNL Hot-Recycled-Solid (HRS) process as a generic, second-generation, rapid pyrolysis retorting system in which recycled shale is the solid heat carrier. In 1984-87, they operated a 1 ton-per-day HRS pilot plant to study retorting chemistry in an actual recirculation loop, Cena (1986). In 1989 they upgraded their laboratory pilot plant to process 4 ton-per-day of commercially sized shale, which will allow them, for the first time, to study pyrolysis and combustion chemistry using the full particle size, to produce enough oil for detailed characterization studies, to study environmental consequences, and to begin answering the many bulk solid handling questions concerning scale-up of the HRS process. In this paper the authors report on the status of their pilot plant operations. They have operated the facility circulating raw shale at ambient temperature and dolomite at elevated temperature. They plan the first hot shale run in November 1990. 5 refs., 16 figs., 4 tabs.
