  • Flax as a Structural Reinforcement for Polymers

    Creator:
    McGeorge, Haley K.
    Abstract:
    Flax fibers are frequently used as a sustainable and recyclable reinforcement for composite materials in aesthetic applications (ex. car interiors). Flax fibers are biodegradable and can be sustainably harvested. Furthermore, the question of how to dispose of flax reinforced materials after the end of their lifetime can be solved in...

  • Feasibility of GOTHIC for a Pressurized Conduction Cooldown Event in the High Temperature Test Facility

    Creator:
    Brawley, Luke P.
    Abstract:
    The purpose of this work was to explore the feasibility of using the GOTHIC thermal hydraulics software package to model a pressurized conduction cooldown event in the High Temperature Test Facility. To achieve that aim, a model of the facility was constructed in the GOTHIC software and a selection of...

  • Role of Alloying on the Thermal Stability of Duplex Stainless Steel

    Creator:
    Garfinkel, David
    Abstract:
    Duplex stainless steels (DSS) are an attractive potential material in nuclear power generation systems due to an excellent combination of corrosion resistance, strength, toughness, and affordability. Thermal embrittlement caused by phase instability in the temperature range of ~300-550°C severely limits the service temperature of DSS. The rate of embrittlement varies...

  • Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

    Creator:
    Bowen, Michael S.
    Abstract:
    Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

  • Role of Stoichiometry on Ordering in Ni-Cr Alloys

    Creator:
    Teng, Fei
    Abstract:
    Mechanical property degradation due to isothermal ageing is of potential concern for alloys based on the Ni-Cr binary system (e.g., Inconel 690, 625), particularly in nuclear power applications where component lifetimes can exceed 40 years. In the present research, the disorder-order phase transformation, which is the primary mechanism of ageing,...

  • Development of Temperature-Stable Relaxor Dielectrics for High Energy Density Capacitor Applications

    Creator:
    McCue, Connor
    Abstract:
    High performance dielectric materials are needed for high power SiC- or GaN-based electronics which combine the best features of high energy density, low dielectric loss and high reliability and for advanced high-speed and high-voltage energy storage where temperature stability plays an important role in material properties. An ideal capacitor for...

  • Thermal Stability of Advanced Metallic Nuclear Fuel Microstructures

    Creator:
    Wright, Alexander A.
    Abstract:
    Metallic nuclear fuels have long been studied for use in advanced nuclear reactors, with efforts invested in improving the viability of metallic nuclear fuel elements and overall safety of advanced reactor design concepts. During reactor operations, fuel forms undergo restructuring due to a variety of physical phenomena. Expansion of the...

  • Cost to Biomphalaria glabrata of Resisting Infection by Schistosoma mansoni

    Creator:
    Sergi, Clint
    Abstract:
    Schistosomiasis is a neglected tropical disease caused by parasitic trematodes in the genus Schistosoma. 200 million people are infected with schistosomes. Schistosomiasis causes acute and chronic disease, and may lead to death in chronic infections. Schistosomes have a complex life cycle that requires passage through a snail intermediate host. Understanding...

  • A Compact Radioxenon Detection System Using CZT, an Array of SiPMs, and a Plastic Scintillator

    Creator:
    Czyz, Steven A.
    Abstract:
    Several radioxenon isotopes (¹³¹ᵐXe, ¹³³Xe, ¹³³ᵐXe, ¹³⁵Xe) are characteristic byproducts of nuclear explosions, and due to their chemically nonreactive nature can easily escape from tests occurring underground and enter the atmosphere. It has been shown that by utilizing beta-gamma coincidence techniques, the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) can...

  • Nuclear Imperialism: Examining Atomic Test Reactions and UN Intervention in Kwame Nkrumah’s Ghana, 1957-1966

    Creator:
    Bremigan, Shelby R.
    Abstract:
    France’s decision to test their nuclear weapons program in the Sahara in 1960 wholly reshaped how the Cold War infiltrated into West Africa. During a time of nation building, Ghanaian President Kwame Nkrumah urged Ghana and Africa, more broadly, to break ties with colonial powers and rebuke further attempts of...
