Fast Ion Effects on Fishbones and n=1 Kinks in JET Simulated by a Non-perturbative NOVA-KN Code

Description: New global non-perturbative hybrid code, NOVA-KN, and simulations of resonant type modes in JET [Joint European Torus] plasmas driven by energetic H-minority ions are presented. The NOVA-KN code employs the ideal-MHD description for the background plasma and treats non-perturbatively the fast particle kinetic response, which includes the fast ion finite orbit width (FOW) effect. In particular, the n = 1 fishbone mode, which is in precession drift resonance with fast ions, is studied. The NOVA-K… more

Jet Physics at CDF

Description: Jets have been studied by the CDF Collaboration [1] as a means of searching for new particles and interactions, testing a variety of perturbative QCD predictions, and providing input for the global parton distribution function (PDF) fits. Unless otherwise indicated below, the jets were reconstructed using a cone algorithm [2] with cone radius R = 0.7 from data taken at the Fermilab Tevatron collider in Run 2, 2001-2003, with {radical}s = 1.96 TeV. Central jets, in the pseudorapidity range relat… more

An Integrated Accident & Consequence Analysis Approach for Accidental Releases through Multiple Leak Paths

Description: This paper presents a consequence analysis for a postulated fire accident on a building containing plutonium when the resulting outside release is partly through the ventilation/filtration system and partly through other pathways such as building access doorways. When analyzing an accident scenario involving the release of radioactive powders inside a building, various pathways for the release to the outside environment can exist. This study is presented to guide the analyst on how the multiple… more

The Adaptive Response in p53 Cancer Prone Mice: Loss of heterozygosity and Genomic Instability.

Description: The Trp53 gene is clearly associated with increased cancer risk. This, coupled with the broad understanding of its mode of action at the molecular level, makes this gene a good candidate for investigating the relationship between genetic risk factors and spontaneous cancer occurring in a mouse model exposed to low dose radiation. We have shown that adaptive response to chronic low dose radiation could increase cancer latency, as well as overall lifespan. To better understand the molecular proce… more

Modeling reactive geochemical transport of concentrated aqueous solutions in variably saturated media

Description: Concentrated aqueous solutions (CAS) have unique thermodynamic and physical properties. Chemical components in CAS are incompletely dissociated, especially those containing divalent or polyvalent ions. The problem is further complicated by the interaction between CAS flow processes and the naturally heterogeneous sediments. As the CAS migrates through the porous media, the composition may be altered subject to fluid-rock interactions. To effectively model reactive transport of CAS, we must take… more

Modeling of Tritium Annual Flux from Concrete Rubble Buried in the Slit Trenches at the Savannah River Site

Description: Some of the concrete rubble generated from the demolition and destruction of some facilities at the U.S. Department of Energy Savannah River Site contains tritium. The tritium-bearing rubble will be disposed in the E-Area slit trenches. In the past, it was assumed for Performance Assessment (risk) modeling that tritium leached from concrete as if the tritium existed entirely on the concrete surfaces. Although conservative (i.e., overestimates risk associated with the groundwater pathway), this … more

Iron Phosphate Glasses: An Alternative for Vitrifying Certain Nuclear Wastes

Description: The unusual properties and beneficial characteristics of iron phosphate glasses, as viewed from the standpoint of alternative glasses for vitrifying nuclear and hazardous wastes (which contain components that make them poorly suited for vitrification in borosilicate glass), have been investigated by the University of Missouri-Rolla with support from the Environmental Management Science Program (EMSP), DOE [DEFG07- 96ER45618]. During the past year, the corrosion resistance of Inconel 690 and 693… more

Np Analysis of Freshly Separated Material

Description: Np analysis has historically relied upon the Pa/Np secular equilibrium for quantitative results. The Savannah River Site has recently undertaken a mission concerning Np. In this application, Np is separated from Pa, packaged, possibly mixed with other batches, and assayed. The fresh separation and mixing of batches prevents the use of the Pa133 prodigy peaks for assay. This effort was a developmental project novel in the DOE complex. This paper discusses the challenges encountered in the design… more

Component Manufacturing Development for the National Compact Stellarator Experiment (NCSX)

Description: NCSX [National Compact Stellarator Experiment] is the first of a new class of stellarators called compact stellarators which hold the promise of retaining the steady state feature of the stellarator but at a much lower aspect ratio and using a quasi-axisymmetric magnetic field to obtain tokamak-like performance. Although much of NCSX is conventional in design and construction, the vacuum vessel and modular coils provide significant engineering challenges due to their complex shapes, need for hi… more

Structural Analysis of the NCSX Vacuum Vessel

Description: The NCSX (National Compact Stellarator Experiment) vacuum vessel has a rather unique shape being very closely coupled topologically to the three-fold stellarator symmetry of the plasma it contains. This shape does not permit the use of the common forms of pressure vessel analysis and necessitates the reliance on finite element analysis. The current paper describes the NCSX vacuum vessel stress analysis including external pressure, thermal, and electro-magnetic loading from internal plasma disru… more

A Study of Longwave Radiation Codes for Climate Studies: Validation with ARM Observations and Tests in General Circulation Models

Description: One specific goal of the Atmospheric Radiation Measurements (ARM) program is to improve the treatment of radiative transfer in General Circulation Models (GCMs) under clear-sky, general overcast and broken cloud conditions. Our project was geared to contribute to this goal by attacking major problems associated with one of the dominant radiation components of the problem --longwave radiation. The primary long-term project objectives were to: (1) develop an optimum longwave radiation model for u… more

Frequency Selective Surfaces as Near Infrared Electro-Magnetic Filters for Thermophotovoltaic Spectral Control

Description: Frequency selective surfaces (FSS) effectively filter electromagnetic radiation in the microwave band (1 mm to 100 mm). Interest exists in extending this technology to the near infrared (1 {micro}m to 10 {micro}m) for use as a filter of thermal radiation in thermophotovoltaic (TPV) direct energy conversion. This paper assesses the ability of FSS to meet the strict spectral performance requirements of a TPV system. Inherent parasitic absorption, which is the result of the induced currents in the… more
