Advanced Sulfur Control Concepts for Hot Gas Desulfurization Technology. Quarterly Report, October--December 1994 (open access)

Advanced Sulfur Control Concepts for Hot Gas Desulfurization Technology. Quarterly Report, October--December 1994

The goal is the development of simpler and economically superior processing of regenerable sorbents used for control of hydrogen sulfide in hot, high-pressure gas streams in advanced power generating systems. The improved processing will produce an elemental sulfur byproduct. Progress during the past quarter was limited by delays in identifying an appropriate analytical instrument for measuring the concentration of sulfur species (S{sub x}(g), H{sub 2}S, and SO{sub 2} in the regeneration product gas. The ability to carry out this analysis on a real-time basis is an important component of the overall project and we feel that a satisfactory gas analysis procedure should be available before forging ahead with other experimental activities. The primary accomplishment, therefore, was the completion and submission of the Task 3 Project Plan. This plan, which assumed a satisfactory solution to sulfur analysis problem, is included in this quarterly report.

Advanced surface cleaning methods: three years of experience with high pressure ultrapure water rinsing of superconducting cavaties (open access)

Advanced surface cleaning methods: three years of experience with high pressure ultrapure water rinsing of superconducting cavaties

In the last three years we have carried out a large number of tests ofn single cell and multi-cell niobium and Nb{sub 3}Sn cavities at L- band frequencies, which as a final surface cleaning step had been rinsed with high pressure jets of ultrapure water. This treatment resulted in an unprecedented quality and reproducibility of cavity performance. Field emission free surfaces up to peak surface electric fields of E{sup peak} {ge} 45 MV/m were achieved nearly routinely after buffered chemical polishing of niobium surfaces. In addition, residual surface resistances below R{sub res} {le} 10 n{Omega} and as low as R{sub res} = 2 n{Omega} were not uncommon. In 5-cell production cavities of the Cornell/CEBAF shape gradients as high as E{sub acc} =21.5 MV/m corresponding to peak surface fields of E{sub peak} {approx} 55 MV/m have been measured after post purification with Ti without the need for rf-processing. Several Nb{sub 3}Sn - cavities exhibited no field emission loading after high pressure ultrapure water rinsing up to the maximum achievable surface fields of E{sup peak} {approx} 33 MV/m; the field limits were given by the available rf-power. The unprecedented reproducibility of the cavities permitted serial testing of various parameters affecting cavity performance …

Aerosol characteristics in the offgas from a pilot-scale sluicing operation (open access)

Aerosol characteristics in the offgas from a pilot-scale sluicing operation

A pilot-scale study was performed to simulate conditions anticipated during sluicing operations to retrieve waste in single-shell Tank 241-C-106 at the US Department of Energy`s Hanford Site in southeastern Washington. The objective of the study was to identify and characterize the potential aerosol source term at the inlet of the headspace exhaust ventilation system during sluicing operations. The information is needed to support decisions for components to be used in the full-scale operation. A secondary objective was to qualitatively evaluate the visibility during sluicing. Three simulated sluicing tests were performed in the 336 Building`s quarter-scale waste tank facility located at Hanford. Scaling relationships were used to guide modifications to the quarter-scale tank to accommodate tests that simulated tank geometry, sluicing, and ventilation conditions in the full-scale tank. Simulated sluicing fluids were targeted on solid and liquid surfaces during the tests. Test conditions were monitored, and aerosol measurements were made in the offgas ventilation duct. Also during the tests, an in-tank camera was used to monitor visibility.

Affordable housing: Reducing the energy cost burden (open access)

Affordable housing: Reducing the energy cost burden

Residential energy expenditures are a key determinant of housing affordability, particularly for lower Income households. For years, federal, state and local governments and agencies have sought to defray energy expenses and Increase residential energy efficiency for low Income households through legislative and regulatory actions and programs. Nevertheless, household energy costs continue to place a major burden on lower Income families. This issue paper was written to help formulate national energy policy by providing the United States Department of Energy`s (DOE`s) Office of Energy Efficiency and Renewable Energy (EE) with Information to help define the affordable housing issue; Identify major drivers, key factors, and primary stakeholders shaping the affordable housing issue; and review how responding to this Issue may impact EE`s goals and objectives and Influence the strategic direction of the office. Typically, housing affordability is an Issue associated with lower income households. This issue paper adopts this perspective, but it is important to note that reducing energy utility costs can make {open_quotes}better{close_quote} housing affordable to any household regardless of income. As energy efficiency is improved throughout all sectors of the economy, special consideration must be given to low income households. Of all households, low income households are burdened the most …

Aï∂a ∂omi

Access: Use of this item is restricted to the UNT Community
Recording of Mia Schmidt's Aï∂a ∂omi. The spoken word, on which the composers short composition for tape "a rose is a rose" is basing, transfers two antithetical messages. The poem "rose is a rose" written by Gertrude Stein is a love- poem. The composer added sentences, taken from newspaper articles discussing the brutality of the pornographic industry. The poem is represented by this overtone-spectrum in form of sinus-tones or slightly modified sinus-tones. The sentences from the newspaper articles are normally spoken.

Airborne radionuclides of concern and their measurement in monitoring a Comprehensive Test Ban Treaty (open access)

Airborne radionuclides of concern and their measurement in monitoring a Comprehensive Test Ban Treaty

The U.S. Department of Energy (DOE) is conducting radioanalytical developmental programs with the goal of providing near-real-time analysis technology for airborne signature radionuclides which are indicative of a nuclear weapons test in any of the earth`s environments. If a test were conducted in the atmosphere or above the atmosphere, then the full spectrum of fission and activation products, together with residues from the device would be dispersed in the atmosphere. However, if a nuclear test were conducted underground or under water, the emission could range from a major to a very minor vent, and the material released would likely consist mainly of noble gas radionuclides and the radioiodines. Since many of the noble gases decay to form particulate radionuclides, these may serve as the more sensitive signatures. For example, Ba-140 is a daughter of Xe-140 (13.6 s), and Cs-137 is a daughter of Xe-137 (3.82 min). Both of these have been observed in large amounts relative to other fission products in dynamic venting of U.S. underground nuclear detonations. Large amounts of radionuclides are produced from even a comparatively small nuclear detonation. For example, a 10-KT fission device will produce approximately a megacurie of Ba-140 and of several other radionuclides with …

[Alaskan resource development and remote power generation]. Task 7.1 -- Strategic planning. Semi-annual report, January 1--June 30, 1995

Assessment of Alaskan opportunities for demonstrating new technologies for resource development and remote power generation was continued. The design and cost estimates for a demonstration plant to produce coal-water fuel (CWF) from low-sulfur Alaskan subbituminous coal were further reviewed to resolve issues of budget and plant capability. A preliminary evaluation was performed of potential cost and performance benefits to be derived from integrating the CWF plant with the demonstration of the AD Little/Cooper Bessemer CWF-fired diesel engine under the DOE Clean Coal Technology demonstration program. Tests on the Cooper Bessemer engine using Alaskan CWF prepared by the Energy and Environmental Research Center (EERC) were recommended to determine engine performance at two levels of coal cleaning: physical cleaning to about 3%--4% ash or additional chemical cleaning to under 2% ash (dry basis). Assistance was provided to graduate students in the Energy Engineering doctoral program at the University of North Dakota in reference to policy papers prepared by them on advanced power options, repowering strategies, and waste management. The information developed in these papers will be used by the EERC in its ongoing assessment of energy and environmental policy issues relating to its research and development program.

Ein Aleatorischer Spaziergang Durch die stadt

Access: Use of this item is restricted to the UNT Community
Recording of Florian Mutschler's Ein Aleatorischer Spaziergnag Durch die stadt. This work is a reflection on the urban acoustic universe at the same time as a structuralist work on the laser support and the possibilities offered by the readers: 18'19'' of unprocessed sound recordings of urban universes and silence are divided into 99 tracks. By programming the repeat and random keys of his laser reader, the user-listener will transform it into a random music generator in which "acoustic images" will lose their primary meaning of simple "documents" to become sound objects. of an abstract musical montage.
