Accelerated test methods for life prediction of hermetic motor insulation systems exposed to alternative refrigerant/lubricant mixtures. Final report (open access)

Accelerated test methods for life prediction of hermetic motor insulation systems exposed to alternative refrigerant/lubricant mixtures. Final report

In 1992, the Air-Conditioning and Refrigeration Technology Institute, Inc. (ARTI) contracted Radian Corporation to ascertain whether an improved accelerated test method or procedure could be developed that would allow prediction of the life of motor insulation materials used in hermetic motors for air-conditioning and refrigeration equipment operated with alternative refrigerant/lubricant mixtures. Phase 1 of the project, Conceptual Design of an accelerated test method and apparatus, was successfully completed in June 1993. The culmination of that effort was the concept of the Simulated Stator Unit (SSU) test. The objective of the Phase 2 limited proof-of-concept demonstration was to: answer specific engineering/design questions; design and construct an analog control sequencer and supporting apparatus; and conduct limited tests to determine the viability of the SSU test concept. This report reviews the SSU test concept, and describes the results through the conclusion of the proof-of-concept prototype tests in March 1995. The technical design issues inherent in transforming any conceptual design to working equipment have been resolved, and two test systems and controllers have been constructed. Pilot tests and three prototype tests have been completed, concluding the current phase of work. One prototype unit was tested without thermal stress loads. Twice daily insulation property measurements …

Activation and micropore structure determination of carbon-fiber composite molecular sieves. Topical report, 30 March 1994--14 April 1995 (open access)

Activation and micropore structure determination of carbon-fiber composite molecular sieves. Topical report, 30 March 1994--14 April 1995

Progress in developing novel, rigid, monolithic adsorbent carbon fiber composites is described. Carbon fiber composites are activated using steam or CO{sub 2}, in order to produce uniform activation through the material and to control the pore structure and adsorptive properties. There is an overall shrinkage during activation, which is directly correlated with burnoff; burnoff above 40% results in fracture. Burnoffs higher than 10% does not produce any benefit for separation of CH{sub 4}-CO{sub 2} mixtures. Five samples of CFCMS have been prepared for testing as molecular sieves; all have relatively narrow pore size distributions with average pore diameters around 6A.

Adaptive ocean acoustic processing for a shallow ocean experiment (open access)

Adaptive ocean acoustic processing for a shallow ocean experiment

A model-based approach is developed to solve an adaptive ocean acoustic signal processing problem. Here we investigate the design of model-based identifier (MBID) for a normal-mode model developed from a shallow water ocean experiment and then apply it to a set of experimental data demonstrating the feasibility of this approach. In this problem we show how the processor can be structured to estimate the horizontal wave numbers directly from measured pressure sound speed thereby eliminating the need for synthetic aperture processing or a propagation model solution. Ocean acoustic signal processing has made great strides over the past decade necessitated by the development of quieter submarines and the recent proliferation of diesel powered vessels.

Audit of Administration of Cooperative Research and Development Agreements at DOE National Laboratories

DOE established policies to ensure that Cooperative Research and Development Agreements (CRADAS) enhance US competitiveness in the world economy, provide a reasonable return on resources invested, and enable successful commercialization of technologies developed. DOE`s Office of Technology Partnerships issued a General Guidance Memorandum to DOE operations offices establishing policy goals for technology transfer programs, including CRADAS. Our audit disclosed that efforts to manage CRADAs at three national laboratories did not fully achieve DOE`s policy goals outlined in the General Guidance Memorandum. Specifically, the audit showed that: (1) joint work statements did not always contain clearly defined information that allowed DOE to facilitate technology transfer or to evaluate CRADAs potential benefits; (2) CRADA statements of work did not always contain adequate documentation or address potential benefits; (3) the national laboratories reviewed did not have effective mechanisms for continuous self-appraisal or measures of overall program success; and (4) CRADA provisions did not exist to ensure an accurate evaluation of partner contributions.

Beneficial reuse of US DOE Radioactive scrap metal (open access)

Beneficial reuse of US DOE Radioactive scrap metal

The US Department of Energy (DOE) has more than 2.5 million tons of radioactive scrap metal (RSM) that is either in inventory or expected to be generated over the next 25 years as major facilities within the weapons complex are decommissioned. Since much of this metal cannot be decontaminated easily, past practice has been to either retain this material in inventory or ship it to DOE disposal sites for burial. In an attempt to conserve natural resources and to avoid burial of this material at DOE disposal sites, options are now being explored to ``beneficially reuse`` this material. Under the beneficial reuse concept, RSM that cannot be decontaminated and free released is used in applications where the inherent contamination is not a detriment to its end use. This paper describes initiatives currently in progress in the United States that support the DOE beneficial reuse concept.

A comparison of an elliptical multipole wiggler and crystal optics for the production of circularly polarized x-rays (open access)

A comparison of an elliptical multipole wiggler and crystal optics for the production of circularly polarized x-rays

Recently, there has been a great deal of interest in polarization modulated x-ray diffraction and spectroscopy techniques. In particular, the importance of photon helicity in spin-dependent magnetic interactions has expanded the need for high quality circularly polarized x-ray sources with fast switching capabilities. Because circularly polarized photons couple differently with the magnetic moment of an atom than do neutrons, they are able to provide unique magnetic information not accessible by neutron techniques. The development of experiments utilizing circularly polarized x-rays, however, has been hampered by the lack of efficient sources. Two different approaches for the production of circularly polarized x-rays have attracted the most attention; (i) employing specialized insertion devices, and (ii) utilizing x-ray phase retarders based on perfect crystal optics. For soft x-rays (0.1--3.0 keV), source development has centered primarily on insertion devices because there are currently no crystal or multilayer polarizing optics available that cover that full energy range. For harder x-rays (>3.0 keV), however, phase retarding optics have been demonstrated, but whether these optics or insertion devices provide the most efficient circularly polarized x-ray source in this energy regime has remained a matter of contention. Advocates of each method have made qualitative statements about their advantages, i.e., …

Computed isotopic inventory and dose assessment for SRS fuel and target assemblies (open access)

Computed isotopic inventory and dose assessment for SRS fuel and target assemblies

Past studies have identified and evaluated important radionuclide contributors to dose from reprocessed spent fuel sent to waste for Mark 16B and 22 fuel assemblies and for Mark 31 A and 31B target assemblies. Fission-product distributions after a 5- and 15-year decay time were calculated for a ``representative`` set of irradiation conditions (i.e., reactor power, irradiation time, and exposure) for each type of assembly. The numerical calculations were performed using the SHIELD/GLASS system of codes. The sludge and supernate source terms for dose were studied separately with the significant radionuclide contributors for each identified and evaluated. Dose analysis considered both inhalation and ingestion pathways: The inhalation pathway was analyzed for both evaporative and volatile releases. Analysis of evaporative releases utilized release fractions for the individual radionuclides as defined in the ICRP-30 by DOE guidance. A release fraction of unity was assumed for each radionuclide under volatile-type releases, which would encompass internally initiated events (e.g., fires, explosions), process-initiated events, and externally initiated events. Radionuclides which contributed at least 1% to the overall dose were designated as significant contributors. The present analysis extends and complements the past analyses through considering a broader spectrum of fuel types and a wider range of irradiation …

Description of the U.S. Geological Survey`s slug-tests at the Hallam Nuclear Facility, July to November 1994

An aquifer test agreement between the US Department of Energy (USDOE) and the US Geological Survey (USGS) was set up to log and measure the aquifer response in two observation wells, IB and 4C at the Hallam Nuclear Facility, Hallam, Nebraska. Observation wells 1B and 4C are owned by the USDOE and were installed by HWS Technologies Inc. of Lincoln, Nebraska, in June 1993. These observation wells were measured monthly from September 1993 to August 1994 by using a graduated steel tape. The accuracy of these water-level measurements is approximately {plus_minus}0.02 foot. Also well 1B contained a submersible pressure transducer to record hourly water-level data during this same period. During access of the wells, personnel wear clean disposable latex gloves, a hard hat, and safety glasses. Directly following each measurement the steel-tape was rinsed with deionized water and the effluent was disposed of in a 55-gallon drum. For the aquifer tests, observation wells 1B and 4C had submersible pressure transducers installed to monitor water-level responses. These pressure transducers were connected to an electronic data logger (edl) to record the water levels, atmospheric pressure from a barometric pressure gauge, and rainfall data from a tipping-bucket rain gauge.

EUV lithography cost of ownership analysis (open access)

EUV lithography cost of ownership analysis

The cost of fabricating state-of-the-art integrated circuits (ICs) has been increasing and it will likely be economic rather than technical factors that ultimately limit the progress of ICs toward smaller devices. It is estimated that lithography currently accounts for approximately one-third the total cost of fabricating modem ICs({sup 1}). It is expected that this factor will be fairly stable for the forseeable future, and as a result, any lithographic process must be cost-effective before it can be considered for production. Additionally, the capital equipment cost for a new fabrication facility is growing at an exponential rate (2); it will soon require a multibillion dollar investment in capital equipment alone to build a manufacturing facility. In this regard, it is vital that any advanced lithography candidate justify itself on the basis of cost effectiveness. EUV lithography is no exception and close attention to issues of wafer fabrication costs have been a hallmark of its early history. To date, two prior cost analyses have been conducted for EUV lithography (formerly called {open_quotes}Soft X-ray Projection Lithography{close_quotes}). The analysis by Ceglio, et. al., provided a preliminary system design, set performance specifications and identified critical technical issues for cost control. A follow-on analysis by Early, …

EUV reticle pattern repair experiments using 10 KeV neon ions (open access)

EUV reticle pattern repair experiments using 10 KeV neon ions

Any potential lithography must demonstrate an industrially-compatable reticle pattern repair process before the lithographic process can be seriously considered for production. Repair of clear defects on ELTV reticles (i.e., regions on the mask which are reflective and should be non-reflective) requires the deposition of a thin layer of absorbing material. This process has been demonstrated in commercially available tools which were originally developed to repair proximity-print x-ray lithography masks. However, the repair of opaque defects (i.e., the recovery of reflectivity from regions on the reticle covered with an absorber) is more difficult. Opaque defect repair requires the removal of the absorber layer without damaging the underlying multilayer, a process which could degrade the mirror reflectivity. While opaque defect repair processes have been demonstrated in a research environment these processes may not be commercially suitable. We are developing reticle repair processes that will be consistent with a commercially available repair tool. In this paper, we report on our first results.

Evaluation, engineering and development of advanced cyclone processes. Final separating media evaluation and test report (FSMER)

{open_quotes}Evaluation Engineering and Development of Advanced Cyclone Processes{close_quotes} is one of the DOE-PETC sponsored advanced coal cleaning projects, which share a number of specific goals. These goals are to produce a 6% ash product, reject 85% of the parent coal`s pyritic sulfur, recover 85% of the parent coal`s Btu value, and provide products that are less than 30% moisture. The process in this project, as the name implies, relies on a cyclone or cyclonic separator to achieve physical beneficiation based on the gravimetric differences between clean coal and its impurities. Just as important as the cyclonic separator, if not more so, is the selection of a parting liquid or medium for use in the separator. Selection of a separating medium is regarded as a significant portion of the project because it has a profound impact on the required unit operations, the performance of the separator, and economics of the process. The choice of medium especially influences selection of media recovery system(s), and the characteristics of clean coal and refuse products. Since medium selection is such an important aspect of the project, portions of the project are dedicated to the study, evaluation, and selection of the most desirable medium. Though separators …

Evaluation of an eastern shale oil residue as an asphalt additive

An evaluation of eastern shale oil (ESO) residue as an asphalt additive to reduce oxidative age-hardening and moisture susceptibility was conducted. The ESO residue, having a viscosity of 23.9 Pa{sm_bullet}s at 60{degrees}C (140{degrees}F), was blended with three different petroleum-derived asphalts, AAD-1, AAK-1, and AAM-1, that are known to be very susceptible to oxidative aging. Rheological and infrared analyses of the unaged and aged asphalts and the blends were then conducted to evaluate oxidative age-hardening. In addition, the petroleum-derived asphalts and the blends were coated onto three different aggregates, Lithonia granite (RA), a low-absorption limestone (RD), and a silicious Gulf Coast gravel (RL), and compacted into briquets. Successive freeze-thaw cycling was then conducted to evaluate the moisture susceptibility of the prepared briquets. The abbreviations used above for the asphalts and the aggregates are part of the Strategic Highway Research Program nomenclature.
