  • Preliminary design and analysis of a rotating bubble membrane radiator for space-based nuclear power systems

    Creator:
    Webb, Brent Jonathan
    Abstract:
    The development of a novel high temperature space radiator is described. A Rotating Bubble Membrane Radiator (RBMR) combines the best features of heat pipes and droplet radiators while avoiding their negative attributes. The RBMR offers light weight, self deployment, ease of startup and its performance is less affected by acceleration....

  • Ultralight fabric reflux tube thermal vacuum testing

    Creator:
    Pauley, Keith Alan
    Abstract:
    Five Ultra light Fabric Reflux Tubes (UFRTs) were tested in a thermal vacuum chamber at the National Aeronautics and Space Administration's Johnson Space Center in September 1994. These test articles were design and fabricated by staff at the Pacific Northwest Laboratory, operated by Battelle Memorial Institute for the United States...

  • Design of a Self-Regulating Deep Space Nuclear Reactor

    Creator:
    Robinson, Matthew Loren
    Abstract:
    An enabling technology for long duration, deep space missions is the availability of a high power, long-lived power supply. The goal of this work is the design of a self-regulating deep space nuclear reactor. The design objectives are to produce 250 kWth for a 25-year period using the presence of...

  • Nuclear design analysis of low-power (1-30 KWe) space nuclear reactor systems

    Creator:
    Gedeon, Stephen R.
    Abstract:
    Preliminary nuclear design studies have been completed on ten configurations of nuclear reactors for low power (1-30 kWe) space applications utilizing thermionic energy conversion. Additional design studies have been conducted on the TRICE multimegawatt in-core thermionic reactor configuration. In each of the cases, a reactor configuration has been determined which...

  • 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...

  • System modeling and reactor design study of an advanced incore thermionic space reactor

    Creator:
    Lee, Hsing Hui
    Abstract:
    Incore thermionic space reactor design concepts which operate at a nominal power output range of 20 to 50 kWe are described. Details of the neutronic, thermionic, thermal hydraulics and shielding performance are presented. Due to the strong absorption of thermal neutrons by natural tungsten, and the large amount of that...

  • Development of systems analysis program for space reactor studies

    Creator:
    Lewis, Bryan R.
    Abstract:
    An overall systems design code was developed to model an advanced in-core thermionic energy conversion based nuclear reactor system for space applications at power levels of 10 to 50 kWe. The purpose of this work was to provide the overall shell for the systems code and to also provide the...
