Final Report on Atomic Database Project (open access)

Final Report on Atomic Database Project

Atomic physics in hot dense plasmas is essential for understanding the radiative properties of plasmas either produced terrestrially such as in fusion energy research or in space such as the study of the core of the sun. Various kinds of atomic data are needed for spectrum analysis or for radiation hydrodynamics simulations. There are many atomic databases accessible publicly through the web, such as CHIANTI (an atomic database for spectroscopic diagnostics for astrophysical plasmas) from Naval Research Laboratory [1], collaborative development of TOPbase (The Opacity Project for astrophysically abundant elements) [2], NIST atomic spectra database from NIST [3], TOPS Opacities from Los Alamos National Laboratory [4], etc. Most of these databases are specific to astrophysics, which provide energy levels, oscillator strength f and photoionization cross sections for astrophysical elements ( Z=1-26). There are abundant spectrum data sources for spectral analysis of low Z elements. For opacities used for radiation transport, TOPS Opacities from LANL is the most valuable source. The database provides mixed opacities from element for H (Z=1) to Zn (Z=30) The data in TOPS Opacities is calculated by the code LEDCOP. In the Fusion Technology Institute, we also have developed several different models to calculate atomic data and …

Simulation of the Beating Heart Based on Physically Modeling aDeformable Balloon (open access)

Simulation of the Beating Heart Based on Physically Modeling aDeformable Balloon

The motion of the beating heart is complex and createsartifacts in SPECT and x-ray CT images. Phantoms such as the JaszczakDynamic Cardiac Phantom are used to simulate cardiac motion forevaluationof acquisition and data processing protocols used for cardiacimaging. Two concentric elastic membranes filled with water are connectedto tubing and pump apparatus for creating fluid flow in and out of theinner volume to simulate motion of the heart. In the present report, themovement of two concentric balloons is solved numerically in order tocreate a computer simulation of the motion of the moving membranes in theJaszczak Dynamic Cardiac Phantom. A system of differential equations,based on the physical properties, determine the motion. Two methods aretested for solving the system of differential equations. The results ofboth methods are similar providing a final shape that does not convergeto a trivial circular profile. Finally,a tomographic imaging simulationis performed by acquiring static projections of the moving shape andreconstructing the result to observe motion artifacts. Two cases aretaken into account: in one case each projection angle is sampled for ashort time interval and the other case is sampled for a longer timeinterval. The longer sampling acquisition shows a clear improvement indecreasing the tomographic streaking artifacts.

Exact Attractive Non-BPS STU Black Holes (open access)

Exact Attractive Non-BPS STU Black Holes

We develop some properties of the non-BPS attractive STU black hole. Our principle result is the construction of exact solutions for the moduli, the metric and the vectors in terms of appropriate harmonic functions. In addition, we find a spherically-symmetric attractor carrying p{sup 0} (D6 brane) and q{sub a} (D2 brane) charges by solving the non-BPS attractor equation (which we present in a particularly compact form) and by minimizing an effective black hole potential. Finally, we make an argument for the existence of multicenter attractors and conjecture that if such solutions exist they may provide a resolution to the existence of apparently unstable non-BPS ''attractors''.

DISTRIBUTION COEFFICIENTS FOR THE VOGTLE EARLY SITE PERMIT (open access)

DISTRIBUTION COEFFICIENTS FOR THE VOGTLE EARLY SITE PERMIT

A series of sediment distribution coefficients, Kd values, measurements were conducted for Southern Nuclear Company, Inc. in support of their Early Site Permit application at Plant Vogtle, Georgia. Nineteen sediment and a representative groundwater samples from the Vogtle site were provided for the Savannah River National Laboratory to conducted site-specific Co, Cs, and Sr Kd measurements. The median Kd values of Co was 6.5 mL/g, for Sr was 10.0 mL/g, and for Cs was 18.8 mL/g. Cation exchange capacity (6.8 to 33.6 meq/100 g), particle size distribution (70 to 94% sand) and pH (4.7 to 5.2) were also measured in five sediments. The Kd values and the sediment properties values measured in these sediments were consistent with those measured in this region of the country.

Amplitude Linearizers for PEP-II 1.2 MW Klystrons and LLRF Systems (open access)

Amplitude Linearizers for PEP-II 1.2 MW Klystrons and LLRF Systems

The PEP-II B-factory has aggressive current increases planned for luminosity through 2008. At 2.2A (HER) on 4A (LER) currents, we estimate that longitudinal growth rates will be comparable to the damping rates currently achieved in the existing low level RF and longitudinal feedback systems. Prior to having a good non-linear time domain model [1] it was postulated that klystron small signal gain non-linearity may be contributing to measured longitudinal growth rates being higher than linearly predicted growth rates. Five prototype klystron amplitude modulation linearizers have been developed to explore improved linearity in the LLRF system. The linearizers operate at 476 MHz with 15 dB dynamic range and 1 MHz linear control bandwidth. Results from lab measurements and high current beam tests are presented. Future development plans, conclusions from beam testing and ideas for future use of this linearization technique are presented.

Impact of Time Resolution on the Projected Rates of System Penetration by Intermittent Generation Technologies (open access)

Impact of Time Resolution on the Projected Rates of System Penetration by Intermittent Generation Technologies

To hedge against the limited resources of fossil fuels and to reduce the emissions of green house gases, it is expected that our future electricity system will include more intermittent technologies, including wind and PV. To better understand how to develop energy systems that rely on intermittents, systems models are used to assess the cost at which intermittents become competitive, the degree of penetration as their costs are reduced, their impact on the optimal structure of the balance of the system, and their affect on total system costs. Modeling approaches designed for dispatchable technologies are not entirely appropriate for modeling intermittent technologies, since they, naturally, assume that generation can always be dispatched to meet demand. Intermittent generation cannot be dispatched--its output varies from hour to hour and from day to day on its own schedule, heedless to system needs. This research assesses the difference in results associated with the different approaches to modeling intermittency. The analyses compare cases using the hourly loads and intermittent generation patterns, cases in which the loads and generation were averaged over several hours, and cases in which the loads and/or the generation were represented by the annual averaging scheme used in the National Energy Modeling …

SUB-LEU-METAL-THERM-001 SUBCRITICAL MEASUREMENTS OF LOW ENRICHED TUBULAR URANIUM METAL FUEL ELEMENTS BEFORE & AFTER IRRADIATION (open access)

SUB-LEU-METAL-THERM-001 SUBCRITICAL MEASUREMENTS OF LOW ENRICHED TUBULAR URANIUM METAL FUEL ELEMENTS BEFORE & AFTER IRRADIATION

With the shutdown of the Hanford PUREX (Plutonium-Uranium Extraction Plant) reprocessing plant in the 1970s, adequate storage capacity for spent Hanford N Reactor fuel elements in the K and N Reactor pools became a concern. To maximize space utilization in the pools, accounting for fuel burnup was considered. Fuel that had experienced a neutron environment in a reactor is known as spent, exposed, or irradiated fuel. In contrast fuel that has not yet been placed in a reactor is known as green, unexposed, or unirradiated fuel. Calculations indicated that at typical fuel exposures for N Reactor, the spent-fuel critical mass would be twice the critical mass for green fuel. A decision was reached to test the calculational result with a definitive experiment. If the results proved positive, storage capacity could be increased and N Reactor operation could be prolonged. An experiment to be conducted in the N Reactor spent-fuel storage pool was designed and assembled (References 1 and 2) and the services of the Battelle Northwest Laboratories (BNWL) (now Pacific Northwest National Laboratory [PNNL]) critical mass laboratory were procured for the measurements (Reference 3). The experiments were performed in April 1975 in the Hanford N Reactor fuel storage pool. The …
