  • Stability analysis of dynamic heat transfer

    Creator:
    Luo, Shyr Tung
    Abstract:
    The stability analysis for a heated tube system is an important safety feature of a nuclear power plant. Although the system theory is well established for linear systems described by ordinary differential equations, there is still a shortage of theory dealing with a distributed system, which is described by partial...

  • Off-design analysis and control of a wood-fired combined-cycle power plant

    Creator:
    Brawn, Robert Charles
    Abstract:
    This report presents the off-design analysis of various wood-fired combined-cycle power plants using a computer model to simulate plant performance. The combined-cycle systems investigated are characterized by having a woodfueled combustor, an indirect-fired gas turbine, and a Rankine steam cycle. This work was conducted as part of a larger biomass...

  • Multi-objective Optimization of Reservoir Operation Under Uncertainty with Robust and Flexible Decision Variables

    Creator:
    Hosseini, Parnian
    Abstract:
    Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well. The overarching goal...

  • Investigation of the IRWST flow patterns during a simulated station blackout experiment on the OSU APEX facility

    Creator:
    Strohecker, Mark F.
    Abstract:
    The OSU/APEX thermal hydraulic test facility models the passive safety systems of the Westinghouse AP600 advanced light water reactor design. Numerous experiments have been performed to test these systems, the one of focus here is the station blackout scenario. This experiment simulated the complete loss of AC power to all...

  • Feed-and-bleed transient analysis of OSU APEX facility using the modern Code Scaling, Applicability, and Uncertainty method

    Creator:
    Hallee, Brian Todd
    Abstract:
    The nuclear industry has long relied upon bounding parametric analyses in predicting the safety margins of reactor designs undergoing design-basis accidents. These methods have been known to return highly-conservative results, limiting the operating conditions of the reactor. The Best-Estimate Plus Uncertainty (BEPU) method using a modernized version of the Code-Scaling,...

  • Experimental simulations of a rotating bubble membrane radiator for space nuclear power systems

    Creator:
    Al-Baroudi, Homan Mohammed-Zahid
    Abstract:
    A rotating, flat plate condensation experiment has been developed to investigate the heat of the Rotating Bubble Membrane Radiator (RBMR). The RBMR is a proposed heat rejection system for space applications which uses working fluid condensation on the inside surface of a rotating sphere to reject heat to space. The...

    Creator:
    Welter, Kent B.
    Abstract:
    A literature review of current phase separation publications was conducted. Data sets were collected and compiled into a Two-Phase Flow Separation Database. Examination of this database indicating a need for further investigation into the liquid entertainment phenomena for smaller hot-leg to branch diameters and intermittent flow regimes. A detailed analysis...

  • A RETRAN model for a hypothetical steam line break occurring at low power operation of the Trojan Nuclear Plant

    Creator:
    Jensen, Peter John
    Abstract:
    The goal of this study is the modeling of a postulated break of the steam line at the containment penetration of the Trojan Nuclear Plant which is owned and operated by Portland General Electric. To perform this modeling, the RETRAN computer code package was utilized. RETRAN is designed to provide...

  • A high power emulation of a wind farm

    Creator:
    Lalla, Chelsea
    Abstract:
    As more wind farms are connected to the grid, the variable nature of wind energy begins to influence grid stability. Energy storage could help smooth the variable nature of wind energy. Laboratory demonstration and exploration of the interaction between different energy storage devices and wind energy could help improve and...

  • 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...
