Spent nuclear fuel sampling strategy

Description: This report proposes a strategy for sampling the spent nuclear fuel (SNF) stored in the 105-K Basins (105-K East and 105-K West). This strategy will support decisions concerning the path forward SNF disposition efforts in the following areas: (1) SNF isolation activities such as repackaging/overpacking to a newly constructed staging facility; (2) conditioning processes for fuel stabilization; and (3) interim storage options. This strategy was developed without following the Data Quality Objecti… more

Description: Construction and setup of twin laboratory gas phase reactors with in-line Gas chromatographic analysers was completed. Calibration and C.G. analysis methods development were carried out, and spreadsheet programs were written for reduction of data to interpretable results. Initial tests were carried out with pentasil zeolite ASM-5 containing very low (0.1%) levels of mercury as potential catalysts for conversion of acetylene/methanol streams to 1,1-dimethoxyethane or to C{sub 2}{sup +} alcohols,… more

Mathematical models and specific absorbed fractions of photon energy in the nonpregnant adult female and at the end of each trimester of pregnancy

Description: Mathematical phantoms representing the adult female at three, six, and nine months of gestation are described. They are modifications of the 15-year-old male/adult female phantom (15-AF phantom) of Cristy and Eckerman (1987). The model of uterine contents includes the fetus, fetal skeleton, and placenta. The model is suitable for dose calculations for the fetus as a whole; individual organs within the fetus (other than the skeleton) are not modeled. A new model for the nonpregnant adult female … more

Synthesis of oxygenate products for high volume fuels applications. Quarterly technical progress report, November 1, 1994--January 31, 1995

Description: The objective of this project is to develop high yield syntheses of oxygenate products that are liquid at room temperature using as starting materials dimethy ether (DME) or methanol. The identified products include: Dimethyl Carbonate (DMC), 1,1-Dimethoxyethane (DMOE), C{sub 2}{sup +} Alcohols/Ethers (C{sub 2}AE). The technical strategy is outlined below: (A) Synthesis of DMC via oxidative carbonylation of DME instead of methanol. Since this synthesis would not co-produce water as a byproduct,… more

Resonant soft x-ray fluorescence studies of novel materials

Description: The authors are using resonant soft x-ray fluorescence at the Advanced Light Source to probe the electronic and geometric structure of novel materials. In the resonant process, a core electron is excited by a photon whose energy is near the core binding energy. In this energy regime the absorption and emission processes are coupled, and this coupling manifests itself in several ways. In boron nitride (BN), the resonant emission spectra reflect the influence of a ``spectator`` electron in an uno… more

Direct aromatization of methane. Quarterly technical progress report No. 10, January 1, 1995--March 31, 1995

Description: Further investigations of assisted pyrolysis by the addition of ethane as a free-radical initiator were carried out during this reporting period. The effects of temperature, space velocity, and ethane/methane ratio, in the presence of quench water, have been addressed. As expected, reaction quenching resulted in lower conversions than without quenching, but also in significantly lower yields of {open_quotes}tar-like{close_quotes} products. High C{sub 2}/C{sub 1} ratios and low space velocities … more

Audit of subsidized ancillary services at the Nevada Test site

Description: The Department and its contractors have participated in at least six reviews since 1991 encompassing aspects of subsidies at the test site. Several of these reviews resulted in reports recommending reductions to the housing, food, and bus services. A strategic planning report completed in November 1994, for example, recommended closing certain food service facilities, increasing housing rates to fair market value, and studying a bus depot system. Other reports echoed the same themes. The Depart… more

Modeling of microencapsulated polymer shell solidification

Description: A finite element transport model has been developed and implemented to complement experimental efforts to improve the quality of ICF target shells produced via controlled-mass microencapsulation. The model provides an efficient means to explore the effect of processing variables on the dynamics of shell dimensions, concentricity, and phase behavior. Comparisons with experiments showed that the model successfully predicts the evolution of wall thinning and core/wall density differences. The mode… more

Decomposable Mandrel Project. Progress report

Description: We report on our progress in developing a new technology to produce both Nova and NIF scale capsules using a depolymerizable mandrel. In this technique we use poly({alpha}-methylstyrene) (PAMS) beads or shells as mandrels which are overcoated with plasma polymer. The poly({alpha}-methylstyrene) mandrel is then thermally depolymerized to gas phase monomer which diffuses away through the more thermally stable plasma polymer coating, leaving a hollow shell. Since our last report we have concentrat… more

Vietnam-U.S. Relations: The Debate Over Normalization

Description: U.S. policymakers face continued debate over normalizing U.S. relations with Vietnam. Some favor greater U.S. flexibility and forward movement in relations with Vietnam; others oppose such changes until Vietnam meets long-standing U.S. conditions, especially accounting more fully for U.S. prisoners of war/missing in action (POW/MIA) from the Vietnam War.
