  • Assessing Several Modeling Approaches in Depletion Studies of a TRISO-Fueled Microreactor

    Creator:
    Hoffman, Keenan J.
    Abstract:
    The impact of MCNP6 depletion resolution on core lifetime is examined in the context of the Snowflake microreactor with explicit TRISO fuel. The change in core lifetime and iso- tope mass as a result of different tracked isotopes, timesteps, and spatial regions is discussed. Calculation speed of a prototype MCNP...

  • Benchmarked simulation of antineutrino source terms for light water reactors during normal operation and diversion scenarios

    Creator:
    Somasundaram, Elanchezhian
    Abstract:
    Detection of reactor antineutrinos for non-proliferation applications has been researched extensively across the globe and is considered as a potential technology to remotely monitor reactor operations without any intrusions to reactor components. Reactor antineutrino detection experiments have been conducted in the past and have proven successful in detecting the changes...

  • Radioxenon generation using highly enriched uranium

    Creator:
    Elliott, Anthony James
    Abstract:
    This work focuses on the generation and collection of four specific radioxenon isotopes; xenon-131m, xenon-133m, xenon-133 and xenon-135. These nuclides are created by fissioning a highly enriched uranium sample using a thermal neutron source from a university research reactor. The three main aspects of this work include: (1) Conducting preliminary...

  • A comparative study of nodal course-mesh methods for pressurized water reactors

    Creator:
    Bukar, Kyari Abba
    Abstract:
    Several computer codes based on one and two-group diffusion theory models were developed for SHUFFLE. The programs were developed to calculate power distributions in a two-dimensional quarter core geometry of a pressurized power reactor. The various coarse-mesh numerical computations for the power calculations yield the following: the Borresen's scheme applied...

  • A Study of Artificial Neural Networks for the Solution of Multi-group Slab Geometry Discrete Ordinates Transport Problems with Material Heterogeneity

    Creator:
    Kumar, Ravi
    Abstract:
    In this thesis, we expand the scope of a previously introduced Artificial Neural Network (ANN) method to solve the slab-geometry discrete ordinates (S$_N$) neutron transport equations. Specifically, we extend the method to energy-dependent (multi-group) fixed source problems involving heterogeneous media and more general boundary conditions - vacuum and incident flux...

  • High speed motion neutron radiography of two-phase flow

    Creator:
    Wang, Shou-Kong Lancelot
    Abstract:
    Current research in the area of two-phase flow utilizes a wide variety of sensing devices, but some limitations exist on the information which can be obtained. Neutron radiography is a feasible alternative to "see" the two-phase flow. A system to perform neutron radiographic analysis of dynamic events which occur on...

  • Analysis of the antineutrino rate during CANDU reactor startup

    Creator:
    Matthews, Christopher
    Abstract:
    Detection systems used to monitor reactor operations are of significant interest as tools for verification of operator declarations. Current reactor site safeguards are limited to visual inspections and intrusive monitoring systems. The recent development of antineutrino detectors may soon allow real-time monitoring from an unobtrusive location. Antineutrinos are produced through...

  • Detection of actinides via nuclear isomer de-excitation

    Creator:
    Francy, Christopher J.
    Abstract:
    The detection of illicit weapons-grade nuclear material is a significant technical challenge receiving a great deal of attention in the nuclear community. A proposed solution is to actively bombard the material under investigation with neutrons, populating nuclear isomers in any potential fissile material. These isomers decay quickly, releasing gamma rays...

  • Control Rod Shadowing Effects in Control Rod Calibrations of The Oregon State TRIGA® Reactor

    Creator:
    Spoerer, Tracey T.
    Abstract:
    Control rod calibration experiment results for the Oregon State TRIGA® Reactor (OSTR) immediately following LEU conversion in 2008, and MCNP® 5 predicted rod worths from the 2008 LEU Conversion Safety Analysis Report (CSAR) are discussed. The reactivity worth of the four OSTR control rods are measured using the rod-pull method....

  • Design, construction, and characterization of a prompt gamma activation analysis facility at the Oregon State University TRIGA® reactor

    Creator:
    Robinson, Joshua A.
    Abstract:
    In this work a prompt gamma neutron activation analysis (PGNAA) facility has been designed, built, and characterized at the Oregon State University TRIGA® reactor. PGNAA is a technique used to determine the presence and quantity of trace elements such as boron, hydrogen and carbon which are more difficult to detect...
