This document describes the original basis for selection of the analog input setpoints for the MICON Automation System. In most cases the setpoints were based on vendor supplied information and design requirements. However, some setpoints were also established based on engineering judgment. These setpoints are subject to change as more experience with operation of the ventilation system is obtained. Revision 1 incorporates minor changes to ensure the document setpoints accurately reflect limits established in OSD-T-151-00019, Rev B-0.

The authors describe and test spai_1.1, a parallel MPIimplementation of the sparse approximate inverse (SPAI) preconditioner.They show that SPAI can be very effective for solving a set of very largeand difficult problems on a Cray T3E. The results clearly show the valueof SPAI (and approximate inverse methods in general) as the viablealternative to ILU-type methods when facing very large and difficultproblems. The authorsstrengthen this conclusion by showing that spai_1.1also has very good scaling behavior.

THERM is a state-of-the-art, Microsoft Windows{trademark}-based computer program developed at Lawrence Berkeley National Laboratory (LBNL) for use by building component manufacturers, engineers, educators, students, architects, and others interested in heat transfer. Using THERM, you can model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, and doors; appliances; and other products where thermal bridges are of concern. THERM's heat-transfer analysis allows you to evaluate a product's energy efficiency and local temperature patterns, which may relate directly to problems with condensation, moisture damage, and structural integrity. THERM's two-dimensional conduction heat-transfer analysis is based on the finite-element method, which can model the complicated geometries of building products. The program's graphic interface allows you to draw cross sections of products or components to be analyzed. To create the cross sections, you can trace imported files in DXF or bitmap format, or input the geometry from known dimensions. Each cross section is represented by a combination of polygons. You define the material properties for each polygon and introduce the environmental conditions to which the component is exposed by defining the boundary conditions surrounding the cross section. Once the model is created, the remaining analysis (mesher and heat transfer) is automatic. You …

In the rush to explore the B system, one should not ignore the potential of rare K decays. The charged and neutral FCNC K {yields} {pi}{nu}{bar {mu}} decays are theoretically very clean, on a par with B {yields} {psi}K{sub S}, which measures {beta}, and much less problematic than B {yields} {pi}{pi} and B{sub s} {yields} K{sup +}K{sup -} or B{sub s} {yields} K*{sup +}K*{sup -} which have been proposed to measure {alpha} and {gamma} respectively. B(K{sup +} {yields} {pi}{sup +}{nu}{bar {nu}}), which in the Standard Model yields information on |V*{sub ts}V{sub td}|, is closely related to the ratio of B{sub d} - {bar B}{sub d} to B{sub s}-{bar B}{sub s}, mixing, which yields |V{sub td}/V{sub ts}|. It is essential to compare such clean measurements from the B and K sectors, because new physics is likely to manifest itself in apparent disagreements[12]. Measuring the branching ratios of K {yields} {pi}{nu}{bar {nu}} decays is a challenge, but the current proven reach in sensitivity for the charged mode and the prospect of measuring the neutral mode at AGS-2000 indicate that this window into flavor physics is on the verge of becoming an exploitable reality.

Unsaturated drip tests have been used to investigate the alteration of unirradiated UO{sub 2} and spent UO{sub 2} fuel in an unsaturated environment such as may be expected in the proposed repository at Yucca Mountain. In these tests, simulated groundwater is periodically injected onto a sample at 90 C in a steel vessel. The solids react with the dripping groundwater and water condensed on surfaces to form a suite of U(VI) alteration phases. Solution chemistry is determined from leachate at the bottom of each vessel after the leachate stops interacting with the solids. A more detailed knowledge of the compositional evolution of the leachate is desirable. By providing just enough water to maintain a thin film of water on a small quantity of fuel in batch experiments, we can more closely monitor the compositional changes to the water as it reacts to form alteration phases.

The Laser Photolysis-Shock Tube (LP-ST) technique coupled with H-atom atomic resonance absorption spectrometry (ARAS) has been used to study reaction, H + CH{sub 2}CO {r_arrow} CH{sub 3} + CO, over the temperature range, 863-1400 K. The results can be represented by the Arrhenius expression, k = (4.85 {+-} 0.70) x 10{sup {minus}11} exp({minus}2328 {+-} 155 K/T) cm{sup 3} molecule{sup {minus}1} s{sup {minus}1}. The present data have been combined with the earlier low temperature flash photolysis-resonance fluorescence measurements to yield a joint three parameter expression, k = 5.44 x 10{sup {minus}14} T{sup 0.8513} exp({minus}1429 K/T) cm{sup 3} molecule{sup {minus}1} s{sup {minus}1}. This is a chemical activation process that proceeds through vibrationally excited acetyl radicals. However, due to the presence of a low lying forward dissociation channel to CH{sub 3} + CO, the present results refer to the high pressure limiting rate constants. Hence, transition state theory with Eckart tunneling is used to explain the data.

This document describes the test documentation required for converting between different versions of the RDD-100 software application. The area of focus is the successful conversion of the master data set between different versions of the database tool and their corresponding data structures.

The transport of a high current relativistic electron beam in a stripline beam kicker is strongly dependent on the wake properties of the structure. The effect of the beam-induced fields on the steering of the beam must be determined for a prescribed trajectory within the structure. A 3-D time domain electromagnetic code is used to determine the wake fields and the resultant Lorentz force on the beam both for an ultra-relativistic electron beam moving parallel to the beamline axis as well as a beam that follows a curved trajectory through the structure. Usually in determining the wake properties of the structure, a wake impedance is found for a beam that is moving parallel to the beamline axis. However, we extend this concept to curved trajectories by calculating beam induced forces along the curved trajectory. Comparisons are made with simple transmission line models of the structure. The wake properties are used in models to transport the beam self-consistently through the structure.

Many regulated entities today charge that environmental regulations have become inefficient and could be made more cost effective. The US Environmental Protection Agency (EPA) has identified several initiatives to help ''reinvent'' environmental regulations and address those charges. At the same time, the President and others are pursuing the development and use of new environmental technologies. Reflecting these trends, Argonne National Laboratory is helping develop a prototype multimedia environmental regulatory program for petroleum refineries operating in the Mure. The project differs from other regulatory reinvention efforts in that it is Mure-oriented and, as a result, may result in recommendations that depart significantly from those from existing regulatory systems. This paper notes the importance of communicating environmental information when developing and implementing regulatory approaches. Two approaches--one goal-based and the other risk-based--are being considered for the prototype regulatory program. Both are site-specific, and the implementation of both requires a significant amount of communication among refiners, regulators, and other stakeholders. Of even greater importance, however, is the communication involved in the development of these approaches. Because these new regulatory approaches could fundamentally change the way regulated entities operate, ideas and concerns of groups likely to be affected by the regulatory prototypes need to be …

Depletion calculations have been performed for the McClellan reactor history from January 1990 through August 1996. A database has been generated for continuing use by operations personnel which contains the isotopic inventory for all fuel elements and fuel-followed control rods maintained at McClellan. The calculations are based on the three-dimensional diffusion theory code REBUS-3 which is available through the Radiation Safety Information Computational Center (RSICC). Burnup-dependent cross-sections were developed at zero power temperatures and full power temperatures using the WIMS code (also available through RSICC). WIMS is based on discretized transport theory to calculate the neutron flux as a function of energy and position in a one-dimensional cell. Based on the initial depletion calculations, a method was developed to allow operations personnel to perform depletion calculations and update the database with a minimal amount of effort. Depletion estimates and calculations can be performed by simply entering the core loading configuration, the position of the control rods at the start and end of cycle, the reactor power level, the duration of the reactor cycle, and the time since the last reactor cycle. The depletion and buildup of isotopes of interest (heavy metal isotopes, erbium isotopes, and fission product poisons) are calculated …

Potential designs for a high power superconducting delay line of approximately 10ms duration are described. The transmitted signal should have low dispersion and little attenuation to recapture the original signal. Such demands cannot be met using conventional metal conductors. This paper outlines a proposal for a new transmission line design using low temperature superconducting material which meets system specifications. The 25W line is designed to carry pulsed signals with an approximate rise time of 8 nsec and a maximum voltage of 25kV. Predicted electrical design and performance of the line is presented.

The purpose of this plan is to describe the preferred remedial alternative for addressing the Gunsite 113 Access Road Unit located at SRS in Aiken, SC, and to provide an opportunity for public input into the remedial action selection process.

The primary objective of this research was to investigate the synthesis and characterization of Ni(OH){sub 2} powders by homogeneous precipitation. Previous research of the same method showed conflicting results and complete characterization of the particle morphology was not carried out. This study has produced precipitates having a composition of 2Ni(OH){sub 2}{center_dot}Ni(HCO{sub 3}){sub 1.85}(NO{sub 3}){sub 0.15}. The XRD patterns showed peaks commonly observed for {alpha}-Ni(OH){sub 2}. The precipitates produced from low and high cation concentration solutions showed that the mean particle size and specific surface area increased with aging time. The high specific surface area measured suggested that the particle growth occurred through the aggregation of nanosized crystallites. The TEM micrographs confirmed that the particles were actually aggregates of thin films or sheets that were crumpled and intertwined together. This work also investigated the effect of dispersant on the particle morphology. The addition of dispersants did not alter the density of the particles implying that the dispersants were not incorporated into the solid phase. A general decrease in mean particle size at each aging time was observed resulting in an increase in specific surface area. The use of dispersants provided steric hindrance for the particles in the solution to aggregate, thus …

Solid-phase extraction (SPE) has grown to be one of the most widely used methods for isolation and preconcentration of a vast range of compounds from aqueous solutions. By modifying polymeric SPE resins with chelating functional groups, the selective uptake of metals was accomplished. The resin, along with adsorbed metals, was vaporized in the ICP and detection of the metals was then possible using either mass or emission spectroscopy. Drug analyses in biological fluids have received heightened attention as drug testing is on the increase both in sports and in the work environment. By using a direct-injection technique, biological fluids can be injected directly into the liquid chromatographic system with no pretreatment. A new surfactant, a sulfonated form of Brij-30 (Brij-S) is shown to prevent the uptake of serum proteins on commercial HPLC columns by forming a thin coating on the silica C18 surface. Excellent separations of eight or more drugs with a wide range of retention times were obtained. The separations had sharper peaks and lower retention times than similar separations performed with the surfactant sodium dodecylsulfate (SDS). Quantitative recovery of a number of drugs with limits of detection near 1 ppm with a 5 {micro}l injection volume were obtained. …

Baryonic matter, in the form of Machos (MAssive Compact Halo Objects), might be a significant constituent of the dark matter that dominates the Milky Way. This article describes how surveys for Machos exploit the gravitational microlens magnification of extragalactic stars. The experimental searches for this effect monitor millions of stars, in some cases every night, looking for magnification events. The early results of these surveys indicate that Machos make up a significant fraction of the dark matter in the Milky Way, and that these objects have stellar masses. Truly substellar objects do not contribute much to the total. Additionally, the relatively high event rate towards the Galactic bulge seems to require that the bulge be elongated, and massive.

This report discusses the following topics on superconductivity: nonlinearities in hard superconductors such as surface impedance of a type II superconductimg half space and harmonic generation and intermodulation due to alternating transport currents; and nonlinearities in superconducting weak links such as harmonic generation by a long Josephson Junction in a superconducting slab.

An application of TDR (Time Domain Reflectometry) was developed and demonstrated for use with the in-situ plasma vitrification (ISPV) environmental restoration project. The technique was simple, using an inexpensive sacrificial TDR probe made out of ordinary coaxial cable. This technique proved its viability for field operation in support of the vitrification process. This presentation will detail the design, construction, operation and field results of the TDR instrumentation that was developed and used in this project. Other practical applications of this technology will be suggested.

This document presents the radiological dose and toxicological exposure calculations for a spray leak inside the unloading area of the 204-AR Waste Unloading Facility.

The Hanford Site is a very diverse Department of Energy (DOE) Nuclear Site in Eastern Washington State that includes: retired reactor facilities, spent fuel storage facilities, chemical separations facilities, laboratories, and plutonium separations facilities. As a result worker routine bioassays requirements may include routine whole body counting for mixed fission products, chest counting for uranium or plutonium, and/or urinalyses for plutonium, ura@u@ strontium-90, and tritium depending on work assignments. In such a situation it is easy to perform unnecessary bioassays and incur unnecessary cost. Program Implementation Fluor Daniel Hanford has been working with the Pacific Northwest National. Laboratories to reduce the number of routine bioassays in the internal dosimetry program while ensuring the program is compliant with regulatory requirements. This has been accomplished by: 1. Clearly identifying what work requires routine bioassay 2. Clearly identifying what routine bioassay is required 3. Having a system in place to make sure personnel who need routine bioassay get it and 4. Taking measures to ensure that workers who doiVt need routine bioassay don`t get it.

The Hanford Facility Dangerous Waste Permit Application is considered to be a single application organized into a General Information Portion (document number DOE/RL-91-28) and a Unit-Specific Portion. The scope of the Unit-Specific Portion is limited to Part B permit application documentation submitted for individual, operating treatment, storage, and/or disposal units, such as the PUREX Storage Tunnels (this document, DOE/RL-90-24). Both the General Information and Unit-Specific portions of the Hanford Facility Dangerous Waste Permit Application address the content of the Part B permit application guidance prepared by the Washington State Department of Ecology (Ecology 1996) and the US Environmental Protection Agency (40 Code of Federal Regulations 270), with additional information needs defined by the Hazardous and Solid Waste Amendments and revisions of Washington Administrative Code 173-303. For ease of reference, the Washington State Department of Ecology alpha-numeric section identifiers from the permit application guidance documentation (Ecology 1996) follow, in brackets, the chapter headings and subheadings. A checklist indicating where information is contained in the PUREX Storage Tunnels permit application documentation, in relation to the Washington State Department of Ecology guidance, is located in the Contents Section. Documentation contained in the General Information Portion is broader in nature and could be used …

A system has been developed for determining temperatures of galvanneal steel during the production process. It is based on an optical method known as phosphor thermometry and it provides for reliable, emissivity-independent measurements. This development is a part of the American Iron and Steel Institute`s (AISI) Advanced Process Control Program, a joint endeavor between the AISI and the U.S. Department of Energy. Galvanneal is a corrosion-resistant steel that is widely used for automotive and other applications. Improved thermometry should enable steelmakers to significantly improve product quality as well as to increase the yield. ultimately decreasing costs.
