Numerical computations of transport coefficients for nonsymmetric plasmas

Description: The linearized drift kinetic equation is solved numerically to obtain the Onsager transport matrix for a three-dimensional toroidal plasma confinement geometry. Local transport coefficients relating the cross-field fluxes to the thermodynamic forces are computed as continuous functions of the collision frequency. In particular, in the low-collision-frequency regime (..nu.. < ..omega../sub b/), the transport resulting from the nonconservation of the longitudinal adiabatic invariant J (due to par… more

Characteristics of ion Bernstein wave heating in JIPPT-II-U tokamak

Description: Using a transport code combined with an ion Bernstein wave tokamak ray tracing code, a modelling code for the ion Bernstein wave heating has been developed. Using this code, the ion Bernstein wave heating experiment on the JIPPT-II-U tokamak has been analyzed. It is assumed that the resonance layer is formed by the third harmonic of deuterium-like ions, such as fully ionized carbon, and oxygen ions near the plasma center. For wave absorption mechanisms, electron Landau damping, ion cyclotron ha… more

Effects of silica redistribution on performance of high-level nuclear waste repositories in saturated geologic formations

Description: Evaluation of the thermohydrological conditions near high-level waste packages is needed for the design of the waste canister and for overall repository design and performance assessment. Most available studies in this area have assumed that the hydrologic properties of the host rock do not change in response to the thermal, mechanical or chemical effects caused by waste emplacement. However, the ramifications of this simplifying assumption have not been substantiated. We have studied dissoluti… more

Determining yttrium in plutonium by anion-exchange x-ray fluorescence

Description: This report describes a method for determining yttrium in plutonium using an anion-exchange separation and x-ray fluorescence. We add zirconium to the plutonium solution as an internal standard. We oxidize the plutonium to Pu + 4 and pass the solution through an anion-exchange column with 8M HCl. The Pu + 4 sorbs to the resin and the yttrium and zirconium pass through completely. We evaporate the eluate solution containing the yttrium and zirconium and transfer it to a 10-ml volumetric flask.

Measurement of Stark amplitudes in the 6SP/sub 1/2/ 7SP/sub 1/2/ transition of atomic thallium

Description: This thesis describes the measurement of Stark amplitude coefficients and US for the 6SP/sub 1/2/ 7SP/sub 1/2/ transition of SVTl in an external static electric field E. The coefficient is determined by measuring the absorption of linearly polarized 293 nm light at the F=1 F'=1 resonance in a cell with known electric field and interaction length, and calibrated thallium density. Then US is determined from the ratio US S/ S of intensities of the F=0 F=1 and F=0 F=0 resonance lines in fluorescenc… more

Neutron powder diffraction at a pulsed neutron source: a study of resolution effects

Description: The General Purpose Powder Diffractometer (GPPD), a high resolution ( d/d = 0.002) time-of-flight instrument, exhibits a resolution function that is almost independent of d-spacing. Some of the special properties of time-of-flight scattering data obtained at a pulsed neutron source will be discussed. A method is described that transforms wavelength dependent data, obtained at a pulsed neutron source, so that standard structural least-squares analyses can be applied. Several criteria are given t… more

Inverse problem for in vivo NMR spatial localization

Description: The basic physical problem of NMR spatial localization is considered. To study diseased sites, one must solve the problem of adequately localizing the NMR signal. We formulate this as an inverse problem. As the NMR Bloch equations determine the motion of nuclear spins in applied magnetic fields, a theoretical study is undertaken to answer the question of how to design magnetic field configurations to achieve these localized excited spin populations. Because of physical constraints in the produc… more

Review of recent progress in the development of Cerenkov Ring Imaging Detectors

Description: The principle behind the Cherenkov Ring Imaging Detectors (CRIDs) involves focussing the Cherenkov light, emitted by a relativistic charged particle in passing through a radiator medium, onto a high efficiency photocathode which can be in turn read out with good spatial resolution, to localize the point of origin of the photoelectrons. This information permits the reconstruction of the circle of Cherenkov light for each particle above threshold, and hence the determination of the Cherenkov angl… more

Equilibrium fluctuation energy of gyrokinetic plasma

Description: The thermal equilibrium electric field fluctuation energy of the gyrokinetic model of magnetized plasma is computed, and found to be smaller than the well-known result <deltaEdeltaE> (k)/8..pi.. = 1/2T/(1 + (klambda/sub D/)/sup 2/) valid for arbitrarily magnetized plasmas. It is shown that, in a certain sense, the equilibrium electric field energy is minimum in the gyrokinetic regime. 13 refs., 2 figs.

Risk assessments for energy systems and role of preliminary degree-of-hazard evaluations

Description: The appropriate approach to risk or hazard assessment can vary considerably, depending on various factors, including the intended application of the results and the time other resources available to conduct the assessment. This paper illustrates three types of interrelated assessments. Although they can be mutually supportive, they have fundamentally different objectives, which require major differences in approach. The example of the overall risk assessment of alternative major energy technolo… more
