  • Advancing the understanding of bulk metallic glasses as structural materials through exploration of mechanical properties

    Creator:
    Naleway, Steven E.
    Abstract:
    Bulk metallic glasses (BMGs) offer a great deal of potential through their near-theoretical strength, potentially high toughness and unique forming and molding traits. However, there are still a number of outstanding issues that bar their widespread use. This thesis describes the investigation of three research questions each designed to further...

  • Characterization of reinforced fill soil, soil-reinforcement interaction, and internal stability of very tall MSE walls

    Creator:
    Walters, James J.
    Abstract:
    In many geotechnical design situations involving tight right-of-way constraints, Mechanically Stabilized Earth (MSE) walls are often the most cost-effective and reliable earth retention technology among available alternatives. However, few well-documented case histories with detailed material testing, instrumentation programs and construction observation of performance are available in the literature. Despite the...

  • Revenue-based spectrum management via Markov decision process

    Creator:
    Zhu, Pingan
    Abstract:
    We consider the problem of wireless spectrum management in cognitive wireless networks that maximizes the revenue for a spectrum operator. Specifically, we study the problem on how a wireless spectrum operator can optimally allocate its limited spectrum to various classes users/devices who pay differently for their spectrum per unit time....

  • Steady State Modeling of the Minimum Critical Core of the Transient Reactor Test Facility

    Creator:
    Alberti, Anthony L.
    Abstract:
    With the advent of next generation reactor systems and new fuel designs, the U.S. Department of Energy (DOE) has identified the need for the resumption of transient testing of nuclear fuels. The DOE has decided that the Transient Reactor Test Facility (TREAT) at Idaho National Laboratory (INL) is best suited...

  • Dynamical System Scaling of Fuel Performance During Reactivity Insertion Accidents

    Creator:
    Dueñas, Alexander M.
    Abstract:
    Fuel qualification timelines for new fuel technology under ideal conditions can take between 20-25 years to be fully qualified from initial concept to deployment as full fuel assemblies. To reduce the timeline and costs, new separate-effects test and integral-effects test experiments, advanced instrumentation, and advanced modeling and simulation tools are...

  • Heat Loss Characterization of NIST-1's Containment Vessel

    Creator:
    Yoshiura, Ramon K.
    Abstract:
    NuScale Power has designed a small modular reactor using natural circulation cooling dependent systems for both steady-state and transient operations. The NuScale Integral Test System (NIST-1) facility was built to supply test data to NuScale Power to verify and validate computer codes for the NuScale Power Mod- ule (NPM) with...

  • Neutronic Analysis of a Liquid Metal Fast Reactor Experiment in the Large-I Position of the Advanced Test Reactor

    Creator:
    Lilley, Benjamin C.
    Abstract:
    Material testing experiments are needed to enable the next generation of nuclear fission reactors. Concluding in 2009, the Boosted Fast Flux Loop (BFFL) project was devised as a way to test fast reactor materials and fuels in the Advanced Test Reactor (ATR), however the experiment location it used is now...

  • Non-Stoichiometry in Bismuth Perovskite Solid Solutions

    Creator:
    Prasertpalichat, Sasiporn
    Abstract:
    The role of A-site non-stoichiometry was investigated in lead-free piezoelectric ceramics based on compositions in the 1-x(Bi₀.₅Na₀.₅TiO₃)-xBaTiO₃ system near the morphotropic phase boundary where x = 0.055, 0.06 and 0.07. The samples were prepared by a conventional solid state mixed oxide route with the A- site stoichiometry modified to incorporate...

  • The Development of a Hybrid Particle-in-Cell Simulation Code in C++ for the Modeling of the SPT-70 Hall Thruster

    Creator:
    Myers, Conner J.
    Abstract:
    In order to support the growing satellite propulsion industry, a hybrid Particle-In-Cell (PIC) simulation with fluid treatment of electrons and neutral particles was developed to model the SPT-70 Hall thruster. The 2D, C++ code assumes azimuthal symmetry and a uniform magnetic field in the radial direction with the simulation domain...
