Analysis of Additional CFT Support at Z=0 for the Silicon Half Trough

Description: The D-Zero silicon trough is segmented into two half troughs. Loading to the Central Fiber Tracker Barrel 1 is at both ends and near Z = 0. The loading near Z = 0 is thought to be 4 lbs at 4 points. The point locations are at +/-45 degrees for each half trough on each side of Z = O. An additional support at Z = O is required to prevent beam sag and out of round distortions to the CFT Barrel 1. An additional joining washer will be attached between barrels 1 and 2 at Z = 0. Also a support ring wi… more

First-principles calculation of optical absorption spectra in conjugated polymers: Role of electron-hole interaction

Description: Experimental and theoretical studies have shown that excitonic effects play an important role in the optical properties of conjugated polymers. The optical absorption spectrum of trans-polyacetylene, for example, can be understood as completely dominated by the formation of exciton bound states. We review a recently developed first-principles method for computing the excitonic effects and optical spectrum, with no adjustable parameters. This theory is used to study the absorption spectrum of tw… more

Economic Sanctions and U.S. Agricultural Exports

Description: Various statutes and regulations authorize the President to restrict or prohibit trade with targeted countries for national security or foreign policy reasons. The exercise of these authorities has resulted in restrictions or prohibitions at times being placed on the export of U.S. agricultural commodities and products. The U.S. government currently restricts exports of agricultural products as part of across-the-board economic sanctions imposed on Cuba and Iraq. Exceptions are made for humanit… more

Labeling of Genetically Modified Foods

Description: Congressional interest in the labeling of genetically modified foods (GM foods) has been rising. So far, two bills have been introduced to mandate that all foods from genetically modified crops (GM crops) be labeled as such. The Food and Drug Administration (FDA) issued its current GM food labeling policy in May 1992. At that time, the agency determined that it would regulate GM foods no differently than foods created by conventional means because FDA considered them substantially equivalent t… more

Time horizon for AFV emission savings under Tier 2

Description: Implementation of the Federal Tier 2 vehicular emission standards according to the schedule presented in the December, 1999 Final Rule will result in substantial reductions of NMHC, CO, NO{sub x}, and fine particle emissions from motor vehicles. Currently, when compared to Tier 1 and even NLEV certification requirements, the emissions performance of automobiles and light-duty trucks powered by non-petroleum (especially, gaseous) fuels (i.e., vehicles collectively termed AFVs) enjoy measurable a… more

Two-phase flow and transport in the air cathode of proton exchange membrane fuel cells

Description: Two-phase flow and transport of reactants and products in the air cathode of proton exchange membrane (PEM) fuel cells is studied analytically and numerically. Four regimes of water distribution and transport are classified by defining three threshold current densities and a maximum current density. They correspond to first appearance of liquid water at the membrane/cathode interface, extension of the gas-liquid two-phase zone to the cathode/channel interface, saturated moist air exiting the ga… more

Experimental observations on the role of the cadmium pool in Mark-IV ER

Description: Argonne National Laboratory (ANL) has developed and demonstrated an electrometallurgical process for the Department of Energy (DOE) to treat sodium bonded spent nuclear fuel. One of the key steps in the demonstration was electrorefining the spent fuel in a molten LiCl-KCl-UCl{sub 3}/liquid cadmium system using a pilot scale electrorefiner (Mark-IV ER). This article summarizes experimental observations and engineering aspects for the roles of the liquid cadmium during electrorefining spent fuel … more

Disposal criticality analysis for the ceramic waste form from the ANL electrometallurgical treatment process - Internal configurations

Description: Criticality safety issues for disposal of the ANL ceramic waste were examined for configurations within the waste package. Co-disposal of ceramic waste and DOE spent fuel is discussed briefly; co-disposal of ANL ceramic and metal wastes is examined in detail. Calculations indicate that no significant potential for criticality exists until essentially all of the important neutron absorbers are flushed from the degraded ceramic waste. Even if all of the neutron absorbers are removed from the cera… more

Recent advances during the treatment of spent EBR-II fuel

Description: Several recent advances have been achieved for the electrometallurgical treatment of spent nuclear fuel. In anticipation of production operations at Argonne National Laboratory-West, development of both electrorefining and metal processing has been ongoing in the post-demonstration phase in order to further optimize the process. These development activities show considerable promise. This paper discusses the results of recent experiments as well as plans for future investigations.

Management of super-grade plutonium in spent nuclear fuel

Description: This paper examines the security and safeguards implications of potential management options for DOE's sodium-bonded blanket fuel from the EBR-II and the Fermi-1 fast reactors. The EBR-II fuel appears to be unsuitable for the packaging alternative because of DOE's current safeguards requirements for plutonium. Emerging DOE requirements, National Academy of Sciences recommendations, draft waste acceptance requirements for Yucca Mountain and IAEA requirements for similar fuel also emphasize the i… more

Robot positioning based on point-to-point motion capability

Description: This paper presents an optimal search method for determining the base location of a robot manipulator so that the robot can have a designated point-to-point (PTP) motion capabilities. Based on the topological characterization of the manipulator workspace and the definitions of various p-connectivity, a computational method is developed for enumerating various PTP motion capabilities into quantitative cost functions. Then an unconstrained search by minimizing the cost function yields the task fe… more

Repository performance assessment of waste forms from the electrometallurgical treatment of sodium-bonded spent nuclear fuel

Description: The ceramic and metal waste forms produced by electrometallurgical treatment of sodium-bonded spent nuclear fuel are undergoing evaluation as to how they will perform within the geologic repository which is proposed to be built at Yucca Mountain. An initial assessment, making use of preliminary degradation models for the waste forms, is described. The analyses are performed with a simplified version of the Total System Performance Assessment--Viability Assessment repository model. Results indic… more

Electrometallurgical treatment demonstration at ANL-West

Description: Electrometallurgical treatment (EMT) was developed by Argonne National Laboratory (ANL) to ready sodium-bonded spent nuclear fuel for geological disposal. A demonstration of this technology was successfully completed in August 1999. EMT was used to condition irradiated EBR-II driver and blanket fuel at ANL-West. The results of this demonstration, including the production of radioactive high-level waste forms, are presented.

Synthesis and characterization of a new microporous cesium silicotitanate (SNL-B) molecular sieve

Description: Ongoing hydrothermal Cs-Ti-Si-O-H{sub 2}O phase investigations has produced several new ternary phases including a novel microporous Cs-silicotitanate molecular sieve, SNL-B with the approximate formula of Cs{sub 3}TiSi{sub 3}O{sub 9.5}{center_dot}3H{sub 2}O. SNL-B is only the second molecular sieve Cs-silicotitanate phase reported to have been synthesized by hydrothermal methods. Crystallites are very small (0.1 x 2 microns) with a blade-like morphology. SNL-B is confirmed to be a 3-dimensiona… more

Quantitative analysis of hydrogen gas formed by aqueous corrosion of metallic uranium

Description: Three unirradiated EBR-II blanket fuel samples containing depleted uranium metal were corrosion tested in simulated J-13 well water at 90 C. The corrosion rate of the blanket uranium metal was then determined relative to H{sub 2} formation. Corrosion of one of the samples was interrupted prior to complete oxidation of the uranium metal and the solid corrosion product was analyzed for UO{sub 2} and UH{sub 3}.
