  • Nuclear safety policy working group recommendations for SEI Nuclear Propulsion safety
    AIP Conference Proceedings, 2008
    Co-Authors: A. C. Marshall, J. C. Sawyer
    Abstract:

    Nuclear Propulsion has been identified as an essential technology for the implementation of the Space Exploration Initiative (SEI). An interagency Nuclear Safety Policy Working Group (NSPWG) was chartered to recommend Nuclear safety policy, requirements, and guidelines for the SEI Nuclear Propulsion program to facilitate the implementation of mission planning and conceptual design studies. The NSPWG developed a top level policy to provide the guiding principles for the development and implementation of the Nuclear Propulsion safety program and the development of Safety Functional Requirements. In addition, the NSPWG reviewed safety issues for Nuclear Propulsion and recommended top level safety requirements and guidelines to address these issues. Safety topics include reactor start‐up, inadvertent criticality, radiological release and exposure, disposal, entry, safeguards, risk/reliability, operational safety, ground testing, and other considerations. All recommendations are in conformance with existing regulations and are formulated with the objectives of assuring safety rather than establishing prescriptive requirements.

  • Nuclear safety policy working group recommendations on Nuclear Propulsion safety for the space exploration initiative
    1993
    Co-Authors: A. C. Marshall, J. C. Sawyer, Robert A. Bari, Hatice S. Cullingford, Alva C. Hardy, James H. Lee, William H. Mcculloch, George F. Niederauer, Kerry Remp, John W. Rice
    Abstract:

    An interagency Nuclear Safety Working Group (NSPWG) was chartered to recommend Nuclear safety policy, requirements, and guidelines for the Space Exploration Initiative (SEI) Nuclear Propulsion program. These recommendations, which are contained in this report, should facilitate the implementation of mission planning and conceptual design studies. The NSPWG has recommended a top-level policy to provide the guiding principles for the development and implementation of the SEI Nuclear Propulsion safety program. In addition, the NSPWG has reviewed safety issues for Nuclear Propulsion and recommended top-level safety requirements and guidelines to address these issues. These recommendations should be useful for the development of the program's top-level requirements for safety functions (referred to as Safety Functional Requirements). The safety requirements and guidelines address the following topics: reactor start-up, inadvertent criticality, radiological release and exposure, disposal, entry, safeguards, risk/reliability, operational safety, ground testing, and other considerations.

  • Report to the Next Generation: Status of NASA's Nuclear Propulsion Technology Program
    AIP Conference Proceedings, 1994
    Co-Authors: Gary L. Bennett, Thomas J. Miller
    Abstract:

    NASA has completed its current technology program on Nuclear Propulsion ‐ both Nuclear thermal Propulsion (NTP) and Nuclear electric Propulsion (NEP). The focus of the NTP studies has been on piloted and cargo missions to Mars (with precursor missions to the Moon) although studies have been conducted to examine the potential uses of NTP for science missions. The focus of the NEP studies shifted from piloted and cargo missions to Mars to space science missions with consideration of combining a science mission with an early demonstration of NEP using the SP‐100 space Nuclear reactor power system.

  • Progress report on Nuclear Propulsion for space exploration and science
    29th Joint Propulsion Conference and Exhibit, 1993
    Co-Authors: Gary L. Bennett, Thomas J. Miller
    Abstract:

    NASA is continuing its work in cooperation with the Department of Energy (DOE) on Nuclear Propulsion - both Nuclear thermal Propulsion (NTP) and Nuclear electric Propulsion (NEP). The focus of the NTP studies remains on piloted and cargo missions to Mars (with precursor missions to the moon) although studies are under way to examine the potential uses of NTP for science missions. The focus of the NEP studies has shifted to space science missions with consideration of combining a science mission with an earlier demonstration of NEP using the SP-100 space Nuclear reactor power system. Both NTP and NEP efforts are continuing in 1993 to provide a good foundation for science and exploration planners. Both NTP and NEP provide a very important transportation resource and in a number of cases enable missions that could not otherwise be accomplished.

  • Journey into tomorrow - Developing Nuclear Propulsion for the Space Exploration Initiative
    1992
    Co-Authors: Kathleen F. Harer, Scott R. Graham, Gary L. Bennett
    Abstract:

    Nuclear Propulsion, either Nuclear thermal Propulsion or Nuclear electric Propulsion, offers the potential of reduced trip times and/or reduced mass into low earth orbit, compared to chemical Propulsion systems. In addition, the greater performance benefits of Nuclear Propulsion can provide the added margin for greater operational flexibility, including mission abort options and increased launch windows. During the 1950s and 1960s experimental and analytical studies showed the feasibility of Nuclear Propulsion. NASA, in cooperation with other agencies and organizations, is currently planning a technology development program for Nuclear Propulsion. The overall objective is to develop at least one NTP concept and one NEP concept for piloted and robotic (e.g., cargo) missions to Mars.

  • Nuclear Propulsion: A key transportation technology for the exploration of Mars
    AIP Conference Proceedings, 1992
    Co-Authors: Gary L. Bennett, Thomas J. Miller
    Abstract:

    Nuclear Propulsion (both Nuclear thermal Propulsion and Nuclear electric Propulsion) represents a key technology for piloted and cargo missions to Mars because it can shorten transit times and/or reduce the initial mass into low Earth orbit when compared to nonNuclear Propulsion systems. Recent studies have identified a number of attributes that will drive the technology development program that NASA has established for Nuclear Propulsion. The overall objective of this program is to develop at least one NTP concept and one NEP concept for piloted and robotic (e.g., cargo) missions to Mars.

  • Nuclear Propulsion for space exploration
    AIP Conference Proceedings, 1992
    Co-Authors: Thomas J. Miller, Gary L. Bennett
    Abstract:

    Nuclear Propulsion has been identified as a key technology by several groups that have studied how to implement President Bush’s directive to go back to the Moon, establish human presences on Mars and explore space beyond Mars. This paper will describe the results of some of the recent studies of the application of both Nuclear electric and Nuclear thermal Propulsion systems in space exploration. This paper will also identify some of the issues that require further study that have a significant effect on the Propulsion system design and selection.

  • Nuclear Propulsion Project Workshop summary
    AIP Conference Proceedings, 1991
    Co-Authors: Thomas J. Miller, John S. Clark, John W. Barnett
    Abstract:

    A joint DOE/DOD/NASA Nuclear Propulsion Project is being planned and implemented under the leadership of the NASA Lewis Research Center. The plan includes both Nuclear Electric Propulsion and Nuclear Thermal Propulsion. Two major national workshops were held in the summer of 1990 to provide a data base for and identify technology needs for a wide range of NTP and NEP concepts. A Joint DOE/DOD/NASA steering committee has reviewed the results and recommendations from the workshops and identified the high priority issues for near‐term implementation. Efforts will be initiated on these issues in FY91 by an interdepartmental/agency team based on available resources.
