  • Fission Gas Bubble Behavior in Uranium Carbide

    Creator:
    Matthews, Christopher
    Abstract:
    The need for cheap reliable energy, while simultaneously avoiding uranium supply constraints makes uranium carbide (UC) fueled Gas Fast Reactors offer an attractive nuclear reactor design. In order to qualify the fuel, an enhanced understanding of the behavior of uranium carbide during operation is paramount. Due to a reduced re-solution...

  • Scaling study of the depressurized conduction cooldown event in the high temperature test facility using RELAP5-3D/ATHENA

    Creator:
    Aldridge, Robert J.
    Abstract:
    In 2008, the Department of Energy (DOE) and Nuclear Regulatory Commission (NCR) decided that the Next Generation Nuclear Plant (NGNP) would be the Very High Temperature Reactor (VHTR). In support of the licensing and validation effort of the VHTR, Oregon State University was tasked with designing, building, and operating a...

  • Irradiation Capsule Development for Composite Fuels for Nuclear Thermal Propulsion

    Creator:
    Thody, Austin
    Abstract:
    Nuclear Thermal Rocket (NTR) designs have received renewed interest due to their superior thermal efficiencies and a rehabilitated desire for space exploration. This has resulted in improved NTR fuel designs that have unique properties that require investigation and testing in order to be more safely designed and operated. Oak Ridge...

  • Feasibility study on a soluble boron-free small modular reactor

    Creator:
    Mart, Justin R.
    Abstract:
    The elimination of soluble boron creates several advantages for Small Modular Reactor (SMR) operation. Most of these advantages are realized through significant core simplification (removal of pipes, pumping, and purification systems), the removal of the corrosive effects of soluble boron, and from improved safety effects. However, removing soluble boron creates...

  • Cost-Benefit Analysis : Proposed Safety Upgrades to Currently Operating Nuclear Power Plants

    Creator:
    Jordahl, Jonathan T.
    Abstract:
    In the wake of nuclear accidents such as Three Mile Island Unit 2 and Fukushima, the nuclear power industry’s safety record is scrutinized. Today the main concerns lies with hydrogen production in a nuclear reactor core when the zirconium fuel cladding reacts with the water coolant during an accident, creating...

  • A CFD Analysis of a Single Channel in the Mars Hopper Engine

    Creator:
    Koll, Christopher J.
    Abstract:
    The Mars Hopper is an alternative extraterrestrial vehicle for the collection of samples from the Martian surface. This thesis studied the engine of the Mars Hopper to assess the validity of the current planned launch cycle according to current parameters. To do this, the engine was simplified to an average...

  • Proof of Concept of the use of Advanced Computational Accident Scenario Modeling for Safety Margin Economic Evaluation

    Creator:
    Riley, Thomas H.
    Abstract:
    The goal of this project was to pave the way for more data-driven decision making when considering safety within Nuclear Engineering by proving the concept of new and innovative accident scenario modeling techniques for the analysis of the economics of nuclear safety margins. To do this, a simple, if extremely...

  • Experimental Investigation of the Transition to Natural Convection in HTGR Applications using the Oregon State SFSETF

    Creator:
    Fishler, Joshua D.
    Abstract:
    High Temperature Gas Reactors (HTGRs) are positioned to disrupt local and global markets via their unique ability to produce carbon-free process heat, high efficiency power generation, and passively safe operational features. However, significant impediments still exist to delay deployment of this particular technology, including a lack of experimental data, verified...

  • Orb Web Vibrations: Modeling, Localization, and Measurement

    Creator:
    Otto, Andrew W.
    Abstract:
    The orb web is a multipurpose structure---serving as a home for its inhabitant spider, as a prey capture device, and as a physical extension of the spider’s sensing abilities. Biologists are particularly interested in the spider’s ability to locate prey trapped in its web by sensing the vibrations induced from...

  • Molybdenum-99 production in the Oregon State TRIGA reactor : analysis of the reactor design using a new LEU target as fuel

    Creator:
    Hummel, Andrew J.
    Abstract:
    The most widely used and versatile medical radioisotope today is technetium-99m. Roughly 30 million people depend on this radioisotope for diagnostic procedures each year, and this demand is expected to grow. Although there are numerous ways of procuring this isotope, the most common and most practical, for reasons to be...
