D-Zero Signal Board Feed-Thru, Instrumentation and Hi-Voltage Boxes (open access)

D-Zero Signal Board Feed-Thru, Instrumentation and Hi-Voltage Boxes

The three boxes being reviewed all operate at a pressure of less than 15 psig. Since they are relieved at 13 psig, they fall outside the scopes of the ASME Pressure Vessel Code, Fermilab Engineering Standard SD-37B, and Chapter 5031 of the Fermilab Safety Manual, therefore a Pressure Vessel Engineering Note showing compliance with SD-37B is not required. In calculating the design stresses, only the largest of the three boxes, the signal board feed-thru box, was analyzed. This box had the largest spans and areas and would experience the largest pressure-related forces. The thinnest walls of each box were found to be in the top plates and they were also the side of the box which exposed the largest amount of area to internal pressure. The signal board feed-thru box top plate had at least twice the pressure area than either the instrumentation or hi-voltage boxes' top plates. This large disparity overshadows the slight difference in top plate thicknesses between the three boxes (0.56-inch vs. 0.25-inch and 0.3125-inch, respectively). Therefore, we felt the analysis of the larger signal board feedthru box would justify the design of the smaller instrumentation and hi-voltage boxes. Appended to the end of this engineering note …

Molecular biological enhancement of coal biodesulfurization. [Rhodococcus, thiobacillus] (open access)

Molecular biological enhancement of coal biodesulfurization. [Rhodococcus, thiobacillus]

The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: clone and characterize the genes encoding the enzymes of the 4S'' pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; return multiple copies of genes to the original host to enhance the biodesulfurization activity of that organism; transfer this pathway into a fast-growing chemolithotropic bacterium; conduct a batch-mode optimization/analysis of scale-up variables.

Modeling of water spraying of field releases of hydrogen fluoride (open access)

Modeling of water spraying of field releases of hydrogen fluoride

The effectiveness of water sprays to absorb HF releases has been recently demonstrated by extended laboratory and field tests. In this paper computer simulations are presented of the Hawk, Nevada Test Site, series of field tests, along with parametric studies of several cases which have not been studied in the field. The model used in these simulations, HFSPRAY, treats the gas-phase as an Eulerean fluid whereas the spray is described according to the Lagrangian approach by a finite number of drops of varying size and trajectory. HFSPRAY simulates the momentum, mass and energy interactions between a water spray and a turbulent plume of HF in air; it is capable of predicting the flow velocities, temperature, water vapor and HF concentration fields in two-dimensional large-geometries, for spraying in any direction, (i.e., down-flow, inclined-down-flow, up-flow, and co-current horizontal flow). 15 refs., 21 figs.

Photoinitiated electron transfer in multi-chromophoric species: Synthetic tetrads and pentads (open access)

Photoinitiated electron transfer in multi-chromophoric species: Synthetic tetrads and pentads

This research project involves the design, synthesis and study of the molecules which mimic many of the important aspects of photosynthetic electron and energy transfer. Specifically, the molecules are designed to mimic the following aspects of natural photosynthetic multistep electron transfer: electron donation from a tetrapyrrole excited singlet state, electron transfer between tetrapyrroles, electron transfer from tetrapyrroles to quinones, and electron transfer between quinones with different redox properties. In addition, they model carotenoid antenna function in photosynthesis (singlet-singlet energy transfer from carotenoid polyenes to chlorophyll) and carotenoid photoprotection from singlet oxygen damage (triplet-triplet energy transfer from chlorophyll to carotenoids).

Heavy ion beam and reactor chamber interface design (open access)

Heavy ion beam and reactor chamber interface design

The design of the heavy-ion beam and the HYLIFE-II reactor chamber interface must provide final focusing quadruple triplets, neutron shielding, fast shutters, vapor condensation and pumping, thermal insulation, and blast resistant structures. The smallest half angle encompassing all beams striking the target might be {plus minus}14{degrees} for an array of 4 {times} 4 beams or {plus minus}9{degrees} if the four corner beams are eliminated, giving a 12-beam array. The target gain drops considerably from the 0{degree} published values because of this finite angle. The assumed one-sided irradiation reduces the number of bending magnets. A 350-MJ yield might be achieved with a 6-MJ driver (gain of 58) (nominal 1000 MWe net power with a repetition rate of 8 Hz). For either lower repetition rate or lower gain the yield must be increased by increasing the driver energy. The beam ports are protected from radiation by an array of vertical and horizontal, neutronically-thick, liquid jets. 6 refs., 7 figs.

HYLIFE-II inertial confinement: Fusion power plant design (open access)

HYLIFE-II inertial confinement: Fusion power plant design

The HYLIFE-2 inertial fusion power plant design study uses a liquid fall, in the form of jets to protect the first structural wall from neutron damage, x rays, and blast to provide a 30-y lifetime. HYLIFE-1 used liquid lithium. HYLIFE 2 avoids the fire hazard of lithium by using a molten salt composed of fluorine, lithium, and beryllium (Li{sub 2}BeF{sub 4}) called Flibe. Access for heavy-ion beams is provided. Calculations for assumed heavy-ion beam performance show a nominal gain of 70 at 5 MJ producing 350 MJ, about 5.2 times less yield than the 1.8 GJ from a driver energy of 4.5 MJ with gain of 400 for HYLIFE-1. The nominal 1 GWe of power can be maintained by increasing the repetition rate by a factor of about 5.2, from 1.5 to 8 Hz. A higher repetition rate requires faster re-establishment of the jets after a shot, which can be accomplished in part by decreasing the jet fall height and increasing the jet flow velocity. Multiple chambers may be required. In addition, although not considered for HYLIFE-1, there is undoubtedly liquid splash that must be forcibly cleared because gravity is too slow, especially at high repetition rates. Splash removal can …

Oscillating liquid flow ICF Reactor

Oscillating liquid flow in a falling molten salt inertial confinement fusion reactor is predicted to rapidly clear driver beam paths of residual liquid droplets. Oscillating flow will also provide adequate neutron and x-ray protection for the reactor structure with a short (2-m) fall distance permitting an 8 Hz repetition rate. A reactor chamber configuration is presented with specific features to clear the entire heavy-ion beam path of splashed molten salt. The structural components, including the structure between beam ports, are shielded. 3 refs., 12 figs.

LLNL Waste Minimization Program Plan (open access)

LLNL Waste Minimization Program Plan

This document is the February 14, 1990 version of the LLNL Waste Minimization Program Plan (WMPP). The Waste Minimization Policy field has undergone continuous changes since its formal inception in the 1984 HSWA legislation. The first LLNL WMPP, Revision A, is dated March 1985. A series of informal revision were made on approximately a semi-annual basis. This Revision 2 is the third formal issuance of the WMPP document. EPA has issued a proposed new policy statement on source reduction and recycling. This policy reflects a preventative strategy to reduce or eliminate the generation of environmentally-harmful pollutants which may be released to the air, land surface, water, or ground water. In accordance with this new policy new guidance to hazardous waste generators on the elements of a Waste Minimization Program was issued. In response to these policies, DOE has revised and issued implementation guidance for DOE Order 5400.1, Waste Minimization Plan and Waste Reduction reporting of DOE Hazardous, Radioactive, and Radioactive Mixed Wastes, final draft January 1990. This WMPP is formatted to meet the current DOE guidance outlines. The current WMPP will be revised to reflect all of these proposed changes when guidelines are established. Updates, changes and revisions to the …

Spin observables for nucleon-nucleon elastic scattering at large momentum transfer (open access)

Spin observables for nucleon-nucleon elastic scattering at large momentum transfer

We discuss amplitudes for elastic nucleon-nucleon scattering at high energy. The helicity-conserving amplitudes are modeled using a combination of the quark-interchange and the Landshoff mechanisms of perturbative QCD. The relative normalization of these two sets of amplitudes involves a leading order form factor'' which we determine empirically. Our theoretically motivated amplitudes provide an economical description of a large body of existing data and make nontrivial predictions for spin observables. 8 refs., 4 figs.
