Porous pavement for control of highway run-off by Mustaque Hossain( Book )

3 editions published in 1989 in English and held by 13 WorldCat member libraries worldwide

A 3-lane by 3500-linear ft portion of an urban highway was constructed of porous pavement. This design resulted from a research study of the use of porous pavement to provide highway drainage. It was determined that after two years of observation, the porous pavement is working as designed. Although the rainfall during the year was slightly less than the typical annual rainfall, there were no storms approaching the ten-year design storms to obtain a full test of the capacity of the system. Pavement deformation as measured in wheel tracks from a straight edge and from pavement elevations measured at the completion of construction are not severe or abnormal. Slight deformation in control sections of conventional pavement occurred immediately after opening to traffic and have undergone no significant change since then. Deformation in the experimental porous pavement is slightly more and occurred over a somewhat longer period than for the control sections. Measurements indicate an increase in moisture content of the subgrade at one location in the porous pavement, but little or no change at the other locations monitored. The increase occurred during the first four or five months after the pavement was put into service. The condition of both the control and experimental pavements are excellent at this time

Fine aggregate shape and surface texture by W. R Meier( Book )

1 edition published in 1989 in English and held by 12 WorldCat member libraries worldwide

Aggregate shape and surface texture of fine aggregate for three different aggregate sources and four levels of degree of crushing were studied by seven different test procedures. Asphalt concrete mixtures using these aggregates were tested for deformation under load by five different tests. Efforts were made to correlate the fine aggregate test measurements to the asphalt concrete deformation properties. The results from three of the fine aggregate tests were correlated with Hveem stability for the best relationships that were developed

US Heavy Ion Beam Research for Energy Density Physics Applicationsand Fusion( )

1 edition published in 2005 in English and held by 6 WorldCat member libraries worldwide

Key scientific results from recent experiments, modeling tools, and heavy ion accelerator research are summarized that explore ways to investigate the properties of high energy density matter in heavy-ion-driven targets, in particular, strongly-coupled plasmas at 0.01 to 0.1 times solid density for studies of warm dense matter, which is a frontier area in high energy density physics. Pursuit of these near-term objectives has resulted in many innovations that will ultimately benefit heavy ion inertial fusion energy. These include: neutralized ion beam compression and focusing, which hold the promise of greatly improving the stage between the accelerator and the target chamber in a fusion power plant; and the Pulse Line Ion Accelerator (PLIA), which may lead to compact, low-cost modular linac drivers
Economic Systems Modeling for Laser IFE and the Potential advantages of Fast Ignition( )

1 edition published in 2006 in English and held by 6 WorldCat member libraries worldwide

An updated systems code for a laser-driven IFE power plant has been developed as part of the U.S. High Average Power Laser (HAPL) program. The cost of electricity (COE) is calculated using standardized methods for fusion reactor studies. In this paper, we describe the systems code and present results for capital cost and COE as a function of key design variables and parameters. We show how the COE varies as a function of driver energy and pulse repetition rate for different lasers. We examine the dependence of COE on other parameters such as laser cost ($/J), laser efficiency, plant efficiency, and net power output of the plant. Finally we compare results for a plant using direct-drive central ignition targets to results with fast ignition targets and note the potential advantages of fast ignition for various assumptions
Analyses in Support of Z-Pinch IFE and Actinide Transmutation - LLNL Progress Report for FY-06( )

1 edition published in 2006 in English and held by 6 WorldCat member libraries worldwide

This report documents results of LLNL's work in support of two studies being conducted by Sandia National Laboratories (SNL): the development of the Z-pinch driven inertial fusion energy (Z-IFE), and the use of Z-pinch driven inertial fusion as a neutron source to destroy actinides from fission reactor spent fuel. LLNL's efforts in FY06 included: (1) Development of a systems code for Z-IFE and use of the code to examine the operating parameter space in terms of design variables such as the Z-pinch driver energy, the chamber pulse repetition rate, the number of chambers making up the power plant, and the total net electric power of the plant. This is covered in Section 3 with full documentation of the model in Appendix A. (2) Continued development of innovative concepts for the design and operation of the recyclable transmission line (RTL) and chamber for Z-IFE. The work, which builds on our FY04 and FY05 contributions, emphasizes design features that are likely to lead to a more attractive power plant including: liquid jets to protect all structures from direct exposure to neutrons, rapid insertion of the RTL to maximize the potential chamber rep-rate, and use of cast flibe for the RTL to reduce recycling and remanufacturing costs and power needs. See Section 4 and Appendix B. (3) Description of potential figures of merit (FOMs) for actinide transmutation technologies and a discussion of how these FOMs apply and can be used in the ongoing evaluation of the Z-pinch actinide burner, referred to as the In-Zinerator. See Section 5. (4) A critique of, and suggested improvements to, the In-Zinerator chamber design in response to the SNL design team's request for feedback on its preliminary design. This is covered in Section 6
Analyses in Support of Z-IFE LLNL Progress Report for FY-05( )

1 edition published in 2005 in English and held by 6 WorldCat member libraries worldwide

The FY04 LLNL study of Z-IFE [1] proposed and evaluated a design that deviated from SNL's previous baseline design. The FY04 study included analyses of shock mitigation, stress in the first wall, neutronics and systems studies. In FY05, the subject of this report, we build on our work and the theme of last year. Our emphasis continues to be on alternatives that hold promise of considerable improvements in design and economics compared to the base-line design. Our key results are summarized here

Technology Issues and Benefits of a Fast Ignition Power Plant with Cone Targets( )

1 edition published in 2003 in English and held by 5 WorldCat member libraries worldwide

The use of cone focus, fast ignition targets, either for direct or indirect drive, promises to lower the required driver size and relax the symmetry requirements in IFE power plants. It may also allow use of chamber concepts previously thought infeasible with a laser driver. These benefits will lower the COE and make IFE plants more competitive at smaller size. Their use also raises unique issues that will impact the design and development of power plant subsystems. Cone targets have a significant mass of high Z material whether or not they have a hohlraum and they are not spherically symmetric. This has implications for target injection, tracking and chamber background gas allowable
Investigating the Heating of a Potassium-Doped Aluminosilicate Ion Source Using a 1 Micron Laser( )

1 edition published in 2004 in English and held by 5 WorldCat member libraries worldwide

The heavy ion fusion (HIF) program is interested in developing a high brightness ion source for high energy density physics (HEDP) experiments. One possible approach to obtaining higher brightness may be to raise the surface temperature of the ion source just prior to extraction. The current ion source material being studied is a layer of potassium-doped aluminosilicate bonded to a tungsten substrate. It is speculated that if the surface temperature of the source is raised above 1200 C (from a steady-state temperature of 900 C) for time periods on the order of 100's of nanoseconds, current densities of greater than 100 mA/cm{sup 2} of ions may be achievable. Typical aluminosilicate sources produce ion current densities (either K+ or Na+ ions) of {approx}10 mA/cm{sup 2} (at 1100 C). A number of heating methods might be possible, including lasers, diode arrays, and flash lamps. Here we assume laser heating. In this preliminary study, we used the LLNL RadHeat code to model the time-temperature history of the surface when hit by laser pulses and illustrate how RadHeat can be used to optimize the surface temperature response. Also of interest is the temperature history of the interface temperature between the ceramic and the metal layers. This is also investigated
Recent U.S. advances in ion-beam-driven high energy densityphysics and heavy ion fusion( )

1 edition published in 2006 in English and held by 5 WorldCat member libraries worldwide

During the past two years, significant experimental and theoretical progress has been made in the US heavy ion fusion science program in longitudinal beam compression, ion-beam-driven warm dense matter, beam acceleration, high brightness beam transport; and advanced theory and numerical simulations. Innovations in longitudinal compression of intense ion beams by> 50 X propagating through background plasma enable initial beam target experiments in warm dense matter to begin within the next two years. They are assessing how these new techniques might apply to heavy ion fusion drivers for inertial fusion energy

Overview of US heavy ion fusion research( )

1 edition published in 2004 in English and held by 4 WorldCat member libraries worldwide

Significant experimental and theoretical progress has been made in the U.S. heavy ion fusion program on high-current sources, injectors, transport, final focusing, chambers and targets for high energy density physics (HEDP) and inertial fusion energy (IFE) driven by induction linac accelerators. One focus of present research is the beam physics associated with quadrupole focusing of intense, space-charge dominated heavy-ion beams, including gas and electron cloud effects at high currents, and the study of long-distance-propagation effects such as emittance growth due to field errors in scaled experiments. A second area of emphasis in present research is the introduction of background plasma to neutralize the space charge of intense heavy ion beams and assist in focusing the beams to a small spot size. In the near future, research will continue in the above areas, and a new area of emphasis will be to explore the physics of neutralized beam compression and focusing to high intensities required to heat targets to high energy density conditions as well as for inertial fusion energy
