For non-reactor nuclear facilities, the U.S. Department of Energy (DOE) does not require that nuclear criticality safety engineers demonstrate qualification for their job. It is likely, however, that more formalism will be required in the future. Current DOE requirements for those positions which do have to demonstrate qualification indicate that qualification should be achieved by using a systematic approach such as performance based training (PBT). Assuming that PBT would be an acceptable mechanism for nuclear criticality safety engineer training in a more formal environment, a site-specific analysis of the nuclear criticality safety engineer job was performed. Based on this analysis, classes are being developed and delivered to a target audience of newer nuclear criticality safety engineers. Because current interest is in developing training for selected aspects of the nuclear criticality safety engineer job, the analysis is incompletely developed in some areas.

The experiments we have been performing are primarily designed to define the extent to which water affects key properties of ashes, powders, and mixtures of sorbents and ashes. We have included selected data from prior quarterly reports in this report for the sake of completeness, and for comparisons with newly-acquired data. In several places in this report samples are referred to by their identification (SID) numbers. Table I provides a brief description of all the samples we have used in this project along with their SID numbers. As suggested by our literature review, our data indicate that water adsorption depends on particle morphology and surface chemistry. Our recent laboratory efforts were primarily directed toward the determination of the effects of adsorbed water on the tensile and cohesive strengths of powders, the development of apparatus for SO{sub 3} and organosiloxane conditioning, and the conditioning of powders and ashes with organosiloxane.

During this quarter some experiments from the previous set were repeated to check the reproducibility of the results. Also, a new set of experiments was carried out to study the effects of (1) collector dosage, (2) Q* -- the nondimensional ratio of air flow rate to slurry flow rate, and (3) slurry pressure on the flow characteristics. Four different Q* values with hydrophobic particles in the feed slurry were studied. The value of A*, the dimensionless ratio of overflow opening area to underflow opening area, was maintained at the same level (A* 1.00). Quartz particles of size {sup {minus}}100 {sup +}200 mesh were used for this study rather than coal particles because they did not abrade and were of a higher density. The reagents used were 40 ppM (water basis) of MIBC frother and 800 g of dodecyl amine collector per ton of dry solids in the suspension. In other experiments with no solids in the feed suspension, collector level in the water was varied at 0, 10 and 20 ppM. At room temperature, quartz is intrinsically hydrophilic while addition of the amine collector renders the quartz particles hydrophobic. The absence of collector will be referred to as the hydrophilic …

This publication provides monthly statistics at the US, Census division, and State levels for net generation, fossil fuel consumption and stocks, quantity and quality of fossil fuels, cost of fossil fuels, electricity sales, revenue, and average revenue per kilowatthour of electricity sold. Data on net generation, fuel consumption, fuel stocks, quantity and cost of fossil fuels are also displayed for the North American Electric Reliability Council (NERC) regions.

ADA Technologies, Inc. (ADA) has completed the bench-scale testing phase of a program to evaluate additives that will improve the collection of fine particles in electrostatic precipitators (ESPs). A bench-scale ESP was installed at the Consolidation Coal Company (CONSOL) combustion research and development facility in Library, PA in order to conduct the evaluation. During a two-week test, four candidate additives were injected into the flue gas ahead of a 100 acfm ESP to determine the effect on fly ash collectability. Two additives were found to reduce the emissions from the ESP. Additives ``C`` and ``D`` performed better than initially anticipated -- reducing emissions initially by 17%. Emissions were reduced by 27% after the ESP was modified by the installation of baffles to minimize sneakage. In addition to the measured improvements in performance, no detrimental effects (i.e., electrode fouling) were observed in the operation of the ESP during the testing. The measures of success identified for the bench-scale phase of the program have been surpassed. Since the additives will affect only non-rapping reentrainment particle losses, it is expected that an even greater improvement in particle collection will be observed in larger-scale ESPs. Therefore, positive results are anticipated during the pilot-scale phase …

The Pacific Northwest is a major exporter of unprocessed softwood logs to foreign countries, such as Japan, that are often sold at premium prices. Consequently, some local mills have had difficulty obtaining unprocessed logs, which has contributed to the loss of timber industry jobs in the Pacific Northwest. Thus, many believe that exporting logs is the economic and moral equivalent of exporting U.S. jobs.

An MHD workshop entitled ``Stabilization of the External Kink and Other MHD Issues`` was held June 1993. This is a summary report of activities at that workshop, structured to respond to the three questions in the charge (letter from J. Willis). The experimental and theoretical status of these issues, and the R&D needs in each area, are addressed. We discuss the potential impact on the TPX and ITER programs of these issues. The workshop participants came from a broad and diverse range of institutions in the fusion program, including international participants. As a result, we believe the summary here reflects some consensus of the community on these very important program issues, and that the TPX and ITER programs will benefit from these discussions. The title of the workshop was chosen to indicate both our knowledge and our uncertainty of MHD phenomena limiting {beta} and causing disruptions in tokamaks. The purpose was to bring together theorists and experimentalist in order to assess our current understanding of the external kink instability at high {beta}, and to assess the potential for passive or active stabilization of the dominant modes. We also outlined the R&D needed for TPX and other future devices. Not only …

Weekly newsletter discussing natural resources, parks, hunting and fishing, and other information related to the outdoors in Texas.

After adoption, these rulemaking actions are codified into the Texas Administrative Code.

The accuracy associated with assessing the environmental consequences of an accidental atmospheric release of radioactivity is highly dependent on our knowledge of the source release rate which is generally poorly known. This paper reports on a technique that integrates the radiological measurements with atmospheric dispersion modeling for more accurate source term estimation. We construct a minimum least squares methodology for solving the inverse problem with no a priori information about the source rate.

This technical report investigates the feasibility of a Crystalline Beam in a weak-focussing storage ring like a Betatron. At the same time the curvature effect due to the bending magnet is also investigated. As a special case, the example of a circular one-dimensional string of electrically charged particles is examined. It is found that the motion of the particles is unstable due to the dependence of the precession movement with respect to each other on their radial displacement. That is a form of negative-mass instability which can be avoided with an alternating-focussing structure corresponding to a transition energy above the energy of the particles. The calculation of the particle-particle interaction as well as of the forces due to the external magnetic field is done directly in the laboratory frame. The retarded potential expressions are used at this purpose.

The authors study the performance of feedforward artificial neural networks in forecasting future values of several different time series. They explore both short- and long-term prediction of several periodic time series. They find that a significant source of error in long-term prediction of time series is introduced by a phase shift between the network output and the time series. They explore the origin of this phase shift and suggest strategies for minimizing its effect. They find that the phase diagrams of the time series and the neural network forecast contain useful diagnostic information.

This invention is comprised of an imaging Fourier transform spectrometer having a Fourier transform infrared spectrometer providing a series of images to a focal plane array camera. The focal plane array camera is clocked to a multiple of zero crossing occurrences as caused by a moving mirror of the Fourier transform infrared spectrometer and as detected by a laser detector such that the frame capture rate of the focal plane array camera corresponds to a multiple of the zero crossing rate of the Fourier transform infrared spectrometer. The images are transmitted to a computer for processing such that representations of the images as viewed in the light of an arbitrary spectral ``fingerprint`` pattern can be displayed on a monitor or otherwise stored and manipulated by the computer.

The United States is emerging from the Cold War era into an exciting, but challenging future. Improving the economic competitiveness of our Nation is essential both for improving the quality of life in the United States and maintaining a strong national security. The research and technical skills used to maintain a leading edge in defense and energy now should be used to help meet the challenge of maintaining, regaining, and establishing US leadership in industrial technologies. Companies recognize that success in the world marketplace depends on products that are at the leading edge of technology, with competitive cost, quality, and performance. Los Alamos National Laboratory and its Industrial Partnership Center (IPC) has the strategic goal to make a strong contribution to the nation`s economic competitiveness by leveraging the government`s investment at the Laboratory: personnel, infrastructure, and technological expertise.

By a memorandum dated September 16, 1992, Office of Federal Procurement Policy OFPP requested that the DOE, Office of Inspector General, conduct a ``special`` audit of the nature and adequacy of DOE`s FFRDC sole-source renegotiation justifications developed since 1985. The OFPP request was based on a July 8, 1992 Senate Subcommittee on Oversight of Government Management report entitled ``Inadequate Federal Oversight of Federally Funded Research and Development Centers,`` which detailed the need for strengthened federal controls over FFRDCs. The Office of Inspector General initiated an inspection in order to review and describe the Department`s history of designating its research laboratories as FFRDCs, and to review the Department`s compliance with the OFPP policy and procedures for establishing and renewing its FFRDCs. We also reviewed DOE`s sole-source renegotiation justifications to non-competitively extend its M&O contractors that manage DOE`s FFRDCs since September 30, 1984.

Pursuant to Section 1340(c) of the Energy Policy Act of 1992 (EPACT), this report presents the Secretary of Energy`s review of data collected by the Federal Government on rates for rail and pipeline transportation of domestic coal, oil, and gas for the years 1988 through 1997, and proposals to develop an adequate data base for each of the fuels, based on the data availability review. This report also presents the Energy Information Administration`s findings regarding the extent to which any Federal agency is studying the impacts of the Clean Air Act Amendments of 1990 (CAAA90) and other Federal policies on the transportation rates and distribution patterns of domestic coal, oil, and gas.

This document outlines a detection-level groundwater monitoring program for the state-approved land disposal structure (SALDS). The SALDS is an infiltration basin proposed for disposal of treated effluent from the 200 Areas of the Hanford Site. The purpose of this plan is to present a groundwater monitoring program that is capable of determining the impact of effluent disposal at the SALDS on the quality of groundwater in the uppermost aquifer. This groundwater monitoring plan presents an overview of the SALDS, the geology and hydrology of the area, the background and indicator evaluation (detection) groundwater monitoring program, and an outline of a groundwater quality assessment (compliance) program. This plan does not provide a plan for institutional controls to track tritium beyond the SALDS.

Synthetic washed ITP slurry (200 g) was oven dried for three days at 60--65{degrees}C in a pan, to a hard solid that stuck to the pan bottom. Between the cracks that formed were a few small particles of unknown size. The solids that were stuck to the pan bottom were pried free and repetitively ground in a mortar and pestle until they all passed through a 40 mesh sieve. This product was then sieved into 50, 80, 100, 170, 200, 325 sieve fractions and the results plotted. A protion of the fines passing the 325 sieve were further separated by air flotation in a glass tube with fritted bottom. Increasing amounts of air were passed up through the tube that floated out increasing fractions of particles after weighing. ITP washed precipitate, ground and dried, had a particle size distribution versus cumulative weight fraction curve between Powered coal and Filter sand. The minimum particle size was about 20 microns.

Review of NMP-NCS-930087, {open_quotes}Nuclear Criticality Safety Evaluation 93-04 Enriched Uranium Receipt (U), July 30, 1993, {close_quotes} was requested of SRTC (Savannah River Technology Center) Applied Physics Group. The NCSE is a criticality assessment to determine the mass limit for Engineered Low Level Trench (ELLT) waste uranium burial. The intent is to bury uranium in pits that would be separated by a specified amount of undisturbed soil. The scope of the technical review, documented in this report, consisted of (1) an independent check of the methods and models employed, (2) independent HRXN/KENO-V.a calculations of alternate configurations, (3) application of ANSI/ANS 8.1, and (4) verification of WSRC Nuclear Criticality Safety Manual procedures. The NCSE under review concludes that a 500 gram limit per burial position is acceptable to ensure the burial site remains in a critically safe configuration for all normal and single credible abnormal conditions. This reviewer agrees with that conclusion.

Control offers an important tool for savings in refineries, mainly by integration of process models into on-line control. This paper is part of a research effort to better understand problems of partial control; control of a Fluid Catalytic Cracker (FCC) is used as example. Goal is to understand better the control problems of an FCC in context of model based control of a refinery, and to understand the general problem of designing partial control systems.
