  • 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 thermal hydraulics analysis of a molybdenum production element for implementation in TRIGA reactors

    Creator:
    Byfield, Patrick
    Abstract:
    The metastable isotope of technetium-99 (Tc-99m) is an important diagnostic tool used in the field of nuclear medicine due to the isotope's 6.0 hour half-life, 140.5 keV γ-decay mechanism, and multiple oxidation states [1,2]. Approximately 70% of the world’s nuclear medicine procedures involve the use of Tc-99m [3]. The conventional...

  • Comprehensive Characterization of Motion of a Helical Coil Due to Flow Induced Vibration

    Creator:
    Harmon, Paul L.
    Abstract:
    Mechanical vibrations compromise the integrity of key components of thermal power plants. Without careful design, strong resonances during steady state operation can wear these components to the point of failure, leading to an unsafe situation that may force a plant to shut down. The purpose of this research is to...

  • Capabilities of Detecting Medical Isotope Facilities through Radioxenon Sampling

    Creator:
    MacDougall, Matthew R.
    Abstract:
    Medical Isotopes are a necessity in modern medicine for cancer treatments and medical imaging. In order to ensure that the needs and demands are met for the medical procedures, facilities are put in place to produce these isotopes. There are over 25 different isotopes of interest being produced by more...

  • Flow Dynamics and Condensation of Film Flows in Small Modular Reactors

    Creator:
    Lee, Dongyoung
    Abstract:
    There is renewed interest in the reliability and safety of nuclear power plants following the Fukushima Daiichi nuclear accident followed by 8.9 magnitude earthquake and Tsunami with the height of 15 m on March 11, 2011. Small Modular Reactors (SMRs) have been developed to improve safety systems by utilizing passive...

  • Flat Plate Free Convective Heat Transfer

    Creator:
    Bristol, Benjanmin R.
    Abstract:
    The OSU MASLWR Test facility is a scaled integral systems LOCA and proof-of-concept test facility for the Multi-Application Small Light Water Reactor design concept. A unique feature of this design is to utilize a small high pressure containment vessel to provide the safety containment function for an integral reactor pressure...

  • Efficacy of Reusing NanoDot OSL Dosimeters Using Optical Bleaching

    Creator:
    Graeper, Gavin
    Abstract:
    Use of optically stimulated luminescence detectors (OSLDs) is rapidly increasing in the area of in vivo dosimetry. OSLDs are relatively new to the market compared to their main competitor, thermoluminescent detectors (TLDs). Currently, not all characteristics of OSLDs have been fully investigated. Landauer’s nanoDot OSLDs were used in conjunction with...

  • Study on Depressurized Loss of Coolant Accident and its Mitigation Method Framework at Very High Temperature Gas Cooled Reactor

    Creator:
    Gutowska, Izabela
    Abstract:
    To understand how a Depressurized Loss of Forced Convection (D-LOFC) initiated from a double-ended guillotine break may affect further operation of a High Temperature Gas Cooled Rector (HTGR), thorough understanding of each specific stage of this event is required. Key considerations that need to be determined is the amount of...

  • Analysis of Carbon-14 Transport from a Contaminated Groundwater Source

    Creator:
    Napier, Jonathan Bamberger
    Abstract:
    Radioecology observes the movement of radioactive isotopes throughout the environment. For radioecology, locations of study are limited to areas accidentally contaminated from a number of sources. The Chalk River Laboratories of Atomic Energy of Canada Limited have stored low level waste since the mid 1940s. In certain instances, the wastes...

    Creator:
    Mullin, Etienne M.
    Abstract:
    The Oregon State University Multi-Application Small Light Water Reactor test facility is employed in a series tests to evaluate condensation heat transfer in small, high pressure containment vessels characteristic of small modular reactor designs under development. This integral system test facility was constructed to demonstrate the feasibility of a pioneering...
