Proof-of-concept tests of the magnetohydrodynamic steam-bottoming system at the DOE Coal-Fired Flow Facility. Final report (open access)

Proof-of-concept tests of the magnetohydrodynamic steam-bottoming system at the DOE Coal-Fired Flow Facility. Final report

The development of coal-fired magnetohydrodynamic (MHD) power can be viewed as consisting of two parts; the topping cycle and the bottoming cycle. The topping cycle consists of the coal combustor, MHD generator and associated components. The bottoming cycle consists of the heat recovery, steam generation, seed recovery/regeneration, emissions control (gas and particulate), ash handling and deposition, and materials evaluation. The report concentrates on the bottoming cycle, for which much of the technology was developed at the University of Tennessee Space Institute (UTSI). Because of the complexity of the required technology, a number of issues required investigation. Of specific concern regarding the bottoming cycle, was the design of the steam cycle components and emissions control. First, the high combustion temperatures and the use of large quantities of potassium in the MHD combustor results in a difference in the composition of the gases entering the bottoming cycle compared to conventional systems. Secondly, a major goal of the UTSI effort was to use a variety of coals in the MHD system, especially the large reserves of high-sulfur coals available in the United States.

Beyond the Brillouin limit with the Penning fusion experiment (open access)

Beyond the Brillouin limit with the Penning fusion experiment

Several years ago, it was proposed that a dense nonneutral plasma could be produced in a Penning trap. Nonneutral plasmas have excellent confinement. Thus, such a dense plasma might produce simultaneously high density and good confinement (as needed for fusion). Recently, this theoretical conjecture has been demonstrated in a small (3 mm radius) electron experiment (PFX). Densities up to 35 times the Brillouin density (limiting number density in a static trap) have been inferred from the observed strong (100:1) spherical focussing. Electrons are injected at low energy from a single pole of the sphere. A surprising observation is the self-organization of the system into a spherical state, which occurs precisely when the trap parameters are adjusted to produce a spherical well. This organization is observed by a bootstrapping which produces a hysteresis. Additional observations which confirm the dense spherical focus are energy-scattered electrons and deflections of an electron probe beam by the space charge of the central focus.

Plutonium-Uranium Extraction (PUREX) facility preclosure work plan (open access)

Plutonium-Uranium Extraction (PUREX) facility preclosure work plan

The dangerous waste permit identification number (WA7890008967)was issued by the U.S. Environmental Protection Agency and the Washington State Department of Ecology. This identification number encompasses a number of treatment, storage, and/or disposal units within the Hanford Facility. One of these treatment, storage, and/or disposal units is the PUREX Facility,currently undergoing a phased closure. The PUREX Facility Preclosure Work Plan submittal differs from closure plans previously submitted by the U.S. Department of Energy, Richland Operations Office to the Washington State Department of Ecology,in that the closure process occurs in three distinct phases as part of the decommissioning process (i.e., transition,surveillance and maintenance, and disposition). Final closure will occur during the disposition phase. This phased decommissioning process is implemented because development of a complete closure plan during the transition phase is impractical and future land use determinations have not been identified. The objective of the transition phase is to place the PUREX Facility in a safe configuration with respect to human health and the environment. Following the transition phase activities, the PUREX Facility will begin the surveillance and maintenance phase of 10 or more years until disposition phase activities commence. The closure plan for the PUREX facility will be prepared during the …

Far-field radiation from a cleaved cylindrical dielectric waveguide (open access)

Far-field radiation from a cleaved cylindrical dielectric waveguide

Angular spread in the far-field radiation pattern of a cleaved dielectric waveguide is determined from the modal structure at the surface of the waveguide using the Smythe vector integral formulation. Essential features: First, a mode exists in the fiber that has no wavelength cutoff--the so-called HE{sub 11} mode. This mode arises when non-azimuthal angular dependence of the incoming radiation is present. Second, the energy flow from this hybrid mode fills the fiber face and is not annularly shaped as opposed to the symmetric TE and TM modes. Third, the HE{sub 11} mode is not polarization dependent in contrast to the TE and TM modes. Fourth, for small differences in the refractive indices between the core and cladding regions, only the HE{sub 11} mode will be supported until the next modes appear around 3.33{lambda}. At this point, three new modes can propagate and the model structure of the radiation becomes more complicated. Fifth, the far-field radiation pattern will have negligibly small angular dependence in the phases of the vector fields when only the lowest mode is present; the amplitude has an overall angular dependent form factor. Furthermore, when other modes are present (above 3.33{lambda}), the phase of the vector fields will …

Scalar mass relations and flavor violations in supersymmetric theories (open access)

Scalar mass relations and flavor violations in supersymmetric theories

Supersymmetry provides the most promising solution to the gauge hierarchy problem. For supersymmetry to stablize the hierarchy, it must be broken at the weak scale. The combination of weak scale supersymmetry and grand unification leads to a successful prediction of the weak mixing angle to within 1{percent} accuracy. If supersymmetry is a symmetry of nature, the mass spectrum and the flavor mixing pattern of the scalar superpartners of all the quarks and leptons will provide important information about a more fundamental theory at higher energies. We studied the scalar mass relations which follow from the assumption that at high energies there is a grand unified theory which leads to a significant prediction of the weak mixing angle; these will serve as important tests of grand unified theories. Two intragenerational mass relations for each of the light generations are derived. A third relation is also found which relates the Higgs masses and the masses of all three generation scalars. In a realistic supersymmetric grand unified theory, nontrivial flavor mixings are expected to exist at all gaugino vertices. This could lead to important contributions to the neutron electric dipole moment, the decay mode p {r_arrow} K{sup 0}{mu}{sup +}, weak scale radiative corrections …

Hanford`s progress toward dry interim storage of K basin`s spent fuel (open access)

Hanford`s progress toward dry interim storage of K basin`s spent fuel

This paper highlights the progress made toward removing the U.S. Department of Energy`s (DOE) approximately 2, 100 metric tons of metallic spent nuclear fuel from two outdated K Basins on the banks of the Columbia River and placing it in safe, economic interim dry storage beginning in December 1997. A new way of doing business at the Hanford Site and within DOE is being used to achieve the fast-track schedule, , cost savings, and public cooperation needed for success. In February 1994, the Spent Nuclear Fuel (SNF) Project was formed to solve serious safety and environmental problems associated with corroding metallic spent fuel stored in 1950`s vintage, leak-prone, water- filled concrete basins located within 365 meters (400 yards) of the last remaining unspoiled section of the Columbia River. Working together, the integrated project team focused on quickly getting the fuel out of the basins and into safe, dry storage. The team involved the public, government, regulators, and other stakeholders and forged a common understanding. The DOE transferred authority to the field to shorten approval times, and Site contractors reengineered processes to improve efficiency. Within nine months of creating the project, a plan was recommended to the DOE. It was approved …

Technology development for iron Fischer-Tropsch catalysis. Quarterly technical progress report No. 4, July 1, 1995--September 30, 1995

The affect of copper promotion on the activity and selectivity of hydrogen pretreated, precipitated iron Fischer-Tropsch catalysts was studied. Fischer-Tropsch synthesis was carried out in the slurry phase in one in one liter continuous stirred tank reactors at a space velocity of 3.lNL h{sup {minus}1} g{sup {minus}1}(Fe), H{sub 2}:CO = 0.7 at either 270{degree}C or 230{degree}C. Catalysts with atomic compositions relative to iron of 10OFe/4.4Si/l.OK and 10OFe/4.4Si/2.6Cu/l.OK were used at 270{degree}C and catalysts with the compositions of 100Fe/4.4Si/4.2K and 10OFe/4.4Si/2.6Cu/4.2K were used at 230{degree}C. XRD and Moessbauer spectroscopy both show that the 10OFe/4.4Si/2.6Cu/l.OK catalyst contained approximately 24% {alpha}-Fe with the remainder Fe{sub 3}O{sub 4} after a 24 h pretreatment with hydrogen at 220{degree}C. Copper promotion was found to substantially increase the activity and productivity of the catalysts. Catalysts promoted with copper reached maximum activity within 100 h of synthesis while catalysts with no copper went through an induction period. The activity of the hydrogen pretreated 10OFe/4.4Si/2.6Cu/1.0K catalyst operated at 270{degree}C was comparable to the activity of the the 100Fe/4.4Si/l.OK catalyst after pretreatment with carbon monoxide or syngas at one atmosphere pressure. However, the activity of the hydrogen pretreated 1O0Fe/4.4Si/2.6Cu/4.2K catalyst at 230{degree}C was found to be substantially lower than the …

Direct conversion of halogen-containing wastes to borosilicate glass (open access)

Direct conversion of halogen-containing wastes to borosilicate glass

Glass has become a preferred waste form worldwide for radioactive wastes: however, there are limitations. Halogen-containing wastes can not be converted to glass because halogens form poor-quality waste glasses. Furthermore, halides in glass melters often form second phases that create operating problems. A new waste vitrification process, the Glass Material Oxidation and dissolution System (GMODS), removes these limitations by converting halogen-containing wastes into borosilicate glass and a secondary, clean, sodium-halide stream.

Tribopolymerization as an anti-wear mechanism. Quarterly progress report, July--September 1996

During this quarterly period, the author has made progress in a number of areas. He has continued to evaluate potential candidates for high load/high speed antiwear action using the approach of generating tribopolymers capable of withstanding high temperatures. Results are promising for ceramics as well as steel. The construction of a new instrument for high temperature studies of both liquid and vapor phase lubrication is almost complete. This will permit studies up to 350 C bulk temperature and considerably higher surface temperatures in controlled vapor-phase and liquid-phase studies. Selected monomers and monomer combinations found to be effective in hexadecane as a carrier fluid have also been tested in other fluids, including synthetic ester lubricant carriers. Additional studies using FTIRM for surface analysis of wear tracks have been made and are continuing. Further industrial contacts have been made to arrange for field testing of selected compounds as antiwear additives. The applications include the lubrication of 2-stroke and 4-stroke engines, machining and cutting, and fuel injector wear, particularly in gas (e.g., natural gas) engines.
