  • The missile hazard of surface traffic accidents to nuclear power plants

    Creator:
    Earle, Otis Keener
    Abstract:
    A method is presented for appraising the hazards to nuclear power plants from missiles from surface traffic accident explosions. Due to the infrequency with which surface traffic accident explosions occur and the poor records kept concerning them, a probabilistic method is chosen to investigate the overall hazards potential to nuclear...

  • SBLOCA analysis for nuclear plant shutdown operations

    Creator:
    Wang, Yi
    Abstract:
    A series of small break loss of coolant accident (SBLOCA) analyses in nuclear plant shutdown operations was simulated using the code RELAP5A,MOD3 version 8.0 to predict the SBLOCA phenomena in the Zion-l nuclear power plant The first objective is to study the impact of SBLOCA (1" and 2" breaks) on...

  • A study of return to saturation oscillations in the OSU APEX thermal hydraulic testing facility

    Creator:
    Franz, Scott C.
    Abstract:
    The purpose of this paper is to describe the flow oscillations which occur in the AP600 long term cooling test facility at Oregon State University. The AP600 system is an advanced pressurized water reactor design utilizing passive emergency cooling systems. A few hours after the initiation of a cold leg...

  • Evaluation of the economic risk from nuclear power

    Creator:
    Hsieh, Kitty A.
    Abstract:
    The cost of ionizing radiation exposure to people and property has been estimated as between $10 and $250 per man-rem by several investigators in the early 70's. These values were considered acceptable by the International Commission on Radiological Protection (ICRP). However, in the U.S. Nuclear Regulatory Commission's (NRC) "Numerical guide...

  • An on-line advanced plant simulator (OLAPS)

    Creator:
    Samuels, Jeffery W.
    Abstract:
    A PC based on-line advanced plant simulator (OLAPS) for high quality simulations of Portland General Electric's Trojan Nuclear Facility is presented. OLAPS is designed to simulate the thermal-hydraulics of the primary system including core, steam generators, pumps, piping and pressurizer. The simulations are based on a five equation model that...

  • 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...

  • Nonintrusive intelligent monitoring for nuclear power plant emergency classification

    Creator:
    Greene, Kenneth R. (Kenneth Ray), 1958-
    Abstract:
    A prototype real-time process monitoring emergency classification expert system, RT/EM-CLASS, has been developed for use at the Trojan Nuclear Power Plant. This knowledge-based system features the integration of electronically sensed plant data with the menu selection data representation of its predecessor, EM-CLASS. This prototype demonstrates the techniques required to acquire...

  • A knowledge-based approach for monitoring and situation assessment at nuclear power plants

    Creator:
    Heaberlin, Joan Oylear
    Abstract:
    An approach for developing a computer-based aid to assist in monitoring and assessing nuclear power plant status during situations requiring emergency response has been developed. It is based on the representation of regulatory requirements and plant-specific systems and instrumentation in the form of hierarchical rules. Making use of inferencing techniques...

  • 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...

  • 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...
