  • Synthesis and testing of a novel soft donor organic extractant molecule for targeted soft metal extraction from aqueous phases

    Creator:
    Gullekson, Brian J.
    Abstract:
    Spent nuclear fuel (SNF) resultant from the generation of nuclear power is a chemically and radiologically diverse system which is advantageous to chemically process prior to geologic disposal. Hydrometallurgy is the primary technology for chemical processing for light water reactor spent fuels, where spent fuel is dissolved in an acid...

  • Design, construction, and analysis of a skin contamination dosimeter

    Creator:
    Cazalas, Edward J.
    Abstract:
    International recommendations provided by the International Commission on Radiation Protection (ICRP), as well as national regulations, set by the U.S. Nuclear Regulatory Commission (NRC), state that the exposure of skin to highly concentrated radioactive sources should be monitored at specified depths in skin and kept below specific dose equivalence levels....

  • Experiments into plasma physics

    Creator:
    Smith, Christopher S.
    Abstract:
    Our research was focused mainly on the field of plasma physics and the creation of plasmas in a laboratory environment. We first began our project with the goal to develop a tabletop Tokamak, a doughnut shaped device that magnetically confines plasmas at pressures greater than one atmosphere. After researching this...

  • Breaking of spherical symmetry in electronic structure, free and immersed atoms in an electron gas

    Creator:
    Dorsett, Skye Forrest
    Abstract:
    Total electronic energies are calculated numerically for free and singly-ionized He, Li, C, and Ne atoms using density functional theory. Immersion energies are calculated for a single C impurity atom embedded or absorbed into a charge-neutral system composed of a free-electron gas with uniform positive background, also called 'jellium'. Nonspherical...

  • Measurement of 239Pu, 237Np, and 238U Fission Product γ Rays

    Creator:
    Tamashiro, Aaron S.
    Abstract:
    Fission product yields (FPYs) are used for a wide range of applications including nuclear fission theory, nuclear reactor design, reactor antineutrino anomaly, stellar nucleosynthesis, and nuclear forensics. These applications rely on FPYs that were last evaluated in 1993, which included measurements from all over the world up until 1993. In...

  • Designing a Spent Fuel Imaging System Using Active Radiography and Passive Tomography Techniques

    Creator:
    Economy, Nikolas
    Abstract:
    Instead of expensive and destructive chemical analysis, nondestructive assay (NDA) through radiography and tomography can be a faster, easier, and more appropriate method of analyzing spent nuclear fuel (SNF). As a preliminary study for the future design of a submersible SNF imaging system, this thesis demonstrates the ability of NDA...

  • Development of a Radioxenon Detection System using Stilbene and Strontium Iodide

    Creator:
    Gadey, Harish R.
    Abstract:
    The Comprehensive Nuclear-Test-Ban Treaty (CTBT) prohibits the testing of nuclear weapons on the face of the earth. The detection of atmospheric radioxenon (131mXe, 133m/133Xe, and 135Xe) plays an important role in the identification of sub-surface clandestine nuclear weapon explosions. Since the radioxenon identified above decay via two radiation in coincidence,...

  • Generation of Multigroup Multiband Cross Sections with Monte Carlo Simulations

    Creator:
    Lam, Adam Q.
    Abstract:
    This is the investigation into The generation of high-fidelity multigroup multiband cross sections from Monte Carlo neutron transport simulations. Previous methods for generating multigroup multiband (MGMB) cross sections, and multigroup cross sections, assume an approximate shape for the scalar flux. This approximate flux shape is the product of an energy-dependent...

  • Evaluation of ²³⁵U and ²³⁸U Fast Fission Product Yields from Godiva-IV Burst Irradiation via Gamma Detection

    Creator:
    Tamashiro, Aaron S.
    Abstract:
    During the past few decades, the U.S. Department of Energy (DOE) has made significant investments to improve nuclear data libraries, as the quality of this data impacts nearly all analyses of nuclear systems. Nuclear fission product yields are one component of these libraries, and are important for the analysis of...

  • Evaluation of partial discharge in inverter driven medium voltage propulsion coils

    Creator:
    Ramme, André
    Abstract:
    Advancements in power electronics to higher power levels and faster switching times allow new machine and systems designs, but also create higher stresses on electric machinery insulation. High performance, pulse-width modulated (PWM) inverters are now available for medium voltage drive systems, and are being considered by the U.S. Navy as...
