  • Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

    Creator:
    Teng, Fei
    Abstract:
    The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

  • Microstructural Characterization of Porosity in U-Mo Low Enriched Uranium Plate Fuel

    Creator:
    Westman, Bjorn E.
    Abstract:
    New low enriched uranium (LEU) fuels are being developed for replacement of high enriched uranium (HEU) fuels in high power research reactors. U-Mo LEU plate fuels have been identified as a candidate for replacement of current HEU fuels. However, U-Mo fuels tend to exhibit accelerated swelling typically at fission densities...

  • Corrosion Resistance of Alloys in Seawater and Supercritical Carbon Dioxide Environments

    Creator:
    Repukaiti, Reyixiati
    Abstract:
    The corrosion resistances of several alloys were investigated to optimize performance and cost in seawater and supercritical CO2 environments. Many alloys are prone to corrosion in seawater and/or supercritical CO2 containing impurity environments. Exposure and electrochemical experiments were conducted in both environments to evaluate alloys’ corrosion resistance. In seawater corrosion...

  • Exploring the Ductility Minimum of Niobium C103 at Intermediate Temperatures using Triaxial Tensile Specimens

    Creator:
    Wood, Thomas N., II
    Abstract:
    This work explores the mechanical properties of single-phase niobium alloy C103 from room temperature to 600°C for the purpose of expanding safe uses of the material into new applications. The study utilizes a symmetrically notched triaxial tensile specimens to manipulate the internal stress field in order to observe the changes...

  • Characterization and Development of Ni-based Superalloys for Supercritical Carbon Dioxide Applications

    Creator:
    Adam, Benjamin M.
    Abstract:
    The advent of supercritical CO2 as a new heat-exchange medium has seen strong interest from the power industry and the energy research field recently. It is advan- tageous in comparison with other heat-exchange cycles, as it can be operated safely at much higher temperatures and pressures, thus increasing the thermal...

  • Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

    Creator:
    Fast, Cody P.
    Abstract:
    Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

  • The Effect of Isothermal Aging on the Development of Long-Range Order in Ni-based Alloys

    Creator:
    Aerne, Nicholas S. J.
    Abstract:
    Nickel (Ni)-based alloys with a high chromium (Cr) content are frequently employed in applications where elevated temperatures and/or corrosive environments are present due to their excellent corrosion resistance and mechanical properties. However, a gap exists around the formation, and kinetics of long-range order (LRO) Ni2Cr phase in both model binary...

  • Artificial Swarm Control Through Learning Based Leadership

    Creator:
    Tuzel, Ovunc
    Abstract:
    Collective migration in animal groups is often guided by distributed leader agents that influence their peers by modulating their motion behaviors. Distributed leadership is a promising navigation strategy for artificial swarms, but designing the leaders’ controllers is difficult due to the swarm’s collective emergent behaviors. The presented research formulates a...

  • Impact of Hot Isostatic Pressing Parameters on Interface Evolution in Uranium Molybdenum Monolithic Plate Fuel

    Creator:
    Koziol, Adam
    Abstract:
    The monolithic (plate type) Uranium 10 wt.\% Molybdenum (U-10Mo) fuel system is promising for a variety of applications, most notably for the replacement of highly enriched uranium (HEU) fuels with low enriched uranium (LEU) fuel in United State High Performance Research Reactors (U.S. HPRRs). Phase transformations and secondary phase formation...

  • Structure and Actuation of Cephalopod-Inspired Soft Robots

    Creator:
    Olson, Gina M.
    Abstract:
    Cephalopod-inspired soft robot arms have been studied as a new type of manipulator. These arms have been proposed for reach and grab tasks, underwater locomotion via swimming and walking, and robotic surgery. However, the capabilities of existing soft arms are limited to simple motions and light loads. Arm design has...
