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...
Resource Type:: Masters Thesis

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...
Resource Type:: Honors College Thesis

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...

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...

Predicting the Effect of Local Conditions on Metal-oxides: Pt/γ-Al₂O₃ Interface and Degradation of α-Cr₂O₃ Passive Film

Creator:: Oware Sarfo, Kofi
Abstract:: Metal-oxides are very important in industrial applications such as thermal barrier coatings, corrosion protection, and heterogeneous catalysis. The wide variety of applications for metal-oxides are derived from the array of properties of metal-oxides. It is, therefore, important to understand and predict the conditions of synthesis and operation to optimize the...

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...

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...
Resource Type:: Masters Thesis

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...
Resource Type:: Dissertation

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...
Resource Type:: Masters Thesis

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...
