  • An MCNP benchmark model of the large experimental ZPPR-19B sodium fast reactor

    Creator:
    Onufer, Mark
    Abstract:
    The International Handbook of Evaluated Reactor Physics Benchmark Experiments contains detailed descriptions of many different reactor facilities. A large portion of these experiments have not been fully modeled due to the unavailability of computational power at the time of the experiment’s execution. With the advent of renewed interest in Sodium...

  • Comparison of HEU and LEU neutron spectra in irradiation facilities at the Oregon State TRIGA® reactor

    Creator:
    Schickler, Robert
    Abstract:
    In 2008, the Oregon State TRIGA® Reactor (OSTR) was converted from highly-enriched uranium (HEU) fuel lifetime improvement plan (FLIP) fuel to low-enriched uranium (LEU) fuel. This effort was driven and supported by the Department of Energy's (DoE's) Reduced Enrichment for Research and Test Reactors (RERTR) program. The basis behind the...

  • 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...

  • The iterative thermal emission Monte Carlo method for thermal radiative transfer

    Creator:
    Long, Alex R.
    Abstract:
    For over 30 years, the Implicit Monte Carlo (IMC) method has been used to solve challenging problems in thermal radiative transfer. These problems are typically optically thick and di ffusive, as a consequence of the high degree of "pseudo-scattering" introduced to model the absorption and reemission of photons from a...

  • Flow Dynamics and Condensation of Film Flows in Small Modular Reactors

    Creator:
    Lee, Dongyoung
    Abstract:
    There is renewed interest in the reliability and safety of nuclear power plants following the Fukushima Daiichi nuclear accident followed by 8.9 magnitude earthquake and Tsunami with the height of 15 m on March 11, 2011. Small Modular Reactors (SMRs) have been developed to improve safety systems by utilizing passive...

  • 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...

  • 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...

  • Diffusion Accelerated Implicit Monte Carlo via Nonlinear Elimination for Thermal Radiative Transfer

    Creator:
    Lam, Adam Q.
    Abstract:
    In this dissertation, we derive and implement a new transport-diffusion hybrid algorithm for solving thermal radiative transfer (TRT) problems. Using the method of nonlinear elimination (NLEM), the TRT system of equations can be written in terms of a transport equation with the absence of scattering and a diffusion equation. The...

  • Vibration Analysis of Advanced Test Reactor Miniplate Hydraulic Test in the OSU HMFTF

    Creator:
    Latimer, Griffen D.
    Abstract:
    Current research on the topic of advanced reactor fuel types include the use of ultrahigh density Uranium-Molybdenum fuels, towards their use in high-performance research reactors. These reactors operate with high power densities, and the increased cooling requirements therefore place high relevance on the fluid-structure interaction with these fuel elements; therefore...

  • 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...
