Chemistry of coal-related microparticles

Description: A new type of electrodynamic balance was designed, constructed and applied to the study of the chemistry of macerals and the chemical reaction between CaO sorbent particles and SO[sub 2]. The single-particle device was coupled to a Raman spectrometer. With this balance a single electrically charged microparticle is suspended in visible and infrared laser beams by means of superposed ac and dc electrical fields. The apparatus was designed to permit gas flow through the chamber so that gas-solid … more

K-edge densitometer (KED)

Description: In 1979, a K-edge densitometer (KED) was installed by the Safeguards Assay group from Los Alamos National Laboratory in the PNC reprocessing plant at Tokai-mura, Japan. It uses an active nondestructive assay technique, KED, to measure the plutonium concentration of the product solution. The measurement uncertainty of an assay depends on the count time chosen, but can be 0.5% or better. The computer hardware and software were upgraded in 1992. This manual describes the operation of the instrumen… more

Requirements for characterization of DWPF canister welds and labels, and estimates of service life

Description: The Department of Energy has established specifications for the DWPF product, which require that the DWPF provide estimates of the service life of the canister label, provide assurance that the DWPF canister will be leaktight when shipped, demonstrate that the contents of the canistered waste form will not lead to internal corrosion of the canister. The DWPF has elected to meet these requirements, in part, by characterizing canisters produced in the facility during the Startup Test Program. Thi… more

Effect of pretreating of host oil on coprocessing

Description: The principal objective of this research is to determine the role that host petroleum-derived oils (1000 [degree]F[sup +]), as that of catalytically treated host oils, play when used as liquefaction solvents in coprocessing with coal. The host oils will be extensively characterized and then pretreated in a number of ways which involve catalytic reactions such as hydrogenation, hydrocracking, and isomerization. The pretreated oils will then be characterized by elemental analysis, catalytic dehyd… more

Internal dosimetry performing dose assessments via bioassay measurements

Description: The Internal Dosimetry Department at the Y-12 Plant maintains a state-of-the-art bioassay program managed under the guidance and regulations of the Department of Energy. The two major bioassay techniques currently used at Y-12 are the in vitro (urinalysis) and in vivo (lung counting) programs. Fecal analysis (as part of the in vitro program) is another alternative; however, since both urine and fecal analysis provide essentially the same capabilities for detecting exposures to uranium, the urin… more

2D deterministic radiation transport with the discontinuous finite element method

Description: This report provides a complete description of the analytic and discretized equations for 2D deterministic radiation transport. This computational model has been checked against a wide variety of analytic test problems and found to give excellent results. We make extensive use of the discontinuous finite element method.

Development of vanadium-phosphate catalysts for methanol production by selective oxidation of methane. Quarterly technical progress report No.2, January--March 1993

Description: During the second quarter, we initiated Task 2 (Process and Catalyst Variable Study). This task involves an investigation of methods for vanadium phosphate (VPO) catalyst synthesis and activation as well as detailed testing of the catalysts produced for activity and selectivity in methane selective oxidation. As we initiated work on Task 2, three problem areas were identified: Preparation of catalysts with P:V ratio greater than 1. Activation of the precursor to produce the B-phase described in… more

The effect of gamma irradiation of the volatility and redox state of simulated DWPF high-level nuclear waste glasses

Description: Gamma-induced volatility of simulated DWPF high-level nuclear waste glasses is highly dependent upon the redox state of the glass. For oxidized glasses with an Fe{sup 2+}/(Fe{sup 2+} + Fe{sup 3+}) ratio < 0.1, no volatility was detected after gamma irradiation. Since the projected DWPF high-level radioactive waste glasses will be oxidized, no significant gamma-induced volatility is expected for these glasses upto the glass transition temperature. For larger pieces of highly-reduced DWPF simulat… more

SDC preshower depth and weighting factor using hanging file data

Description: Often inert material exists in front of a calorimeter. If an electromagnetic (EM) shower initiates in this material, and energy is not sampled by the calorimeter, then energy resolution will be degraded. It is crucial to minimize the amount of inert material. Algorithms using a separate readout of the energy early in the shower (a ``preshower`` detector) can also be used to alleviate the reduced performance. This problem has previously been studied using CDF test beam data. In addition, an EGS … more

Crystalline beam ground state

Description: In order to employ molecular dynamics (MD) methods, commonly used in condensed matter physics, we have derived the equations of motion for a beam of charged particles in the rotating rest frame of the reference particle. We include in the formalism that the particles are confined by the guiding and focusing magnetic fields, and that they are confined in a conducting vacuum pipe while interacting with each other via a Coulomb force. Numerical simulations using MD methods has been performed to ob… more
