Meeting Notes and Presentations The 2011 Nuclear and Emerging Technologies for Space meeting was by all accounts a great success, hosting just under 200 attendees distributed almost evenly among NASA, DOE/national laboratories, industry, and universities. Conference participants were pleased to once again have a venue for discussing the latest research and development in space nuclear technologies, and space exploration missions enabled by those technologies. Summaries for plenary sessions made on the opening day of the conference and focused panel sessions are available below. Where available and approved for release by the presenter, presentations are also available for download by clicking on the presentation title. Speaker biographies can be accessed by clicking on the name of the speaker (biographies not available for panel sessions).

Opening
Remarks The invited speakers, their affiliations, and their presentations were: Space
Nuclear Power and Propulsion: The Good, the Bad and the Ugly Expanding
Science Knowledge: Enabled by Nuclear Power Special Session: Addressing the Non-Technical Challenges of Developing Space Nuclear Technology Chair:
Dr.
Michael Griffin,
former NASA Administrator and King-McDonald Eminent
Scholar for
Mechanical and Aerospace Engineering at the University of Alabama in
Huntsville Fluctuations in space exploration goals are a significant, non-technical obstacle for the end-to-end development and implementation of nuclear and emerging technologies for space exploration. When goals change mid-stream, research and development progress and accomplishments may become partially or completely inapplicable with respect to the new goals. If goal fluctuations are more rapid than the time it takes for research efforts to manifest, then the capabilities the technology would have provided are not obtained. The historical record indicates a cyclic nature in these fluctuations. Explicitly addressing problems stemming from these cycles could be the first step in facilitating implementation of space nuclear systems and other technologies to completion. Panelists opened the session by providing a description of the policy making and technical development work environments; identification of problems, their causes, and possible solutions; and discussion of possible implementation strategies. No prepared remarks are available for download; alternately, a detailed summary is provided at the link below. Full Session Summary - Coming Soon!! Moderator: Dr. Elizabeth Newton Panelists: Dr. Michael Griffin Keynote
Address: by Dr.
Glen Schmidt, former test engineer for the SNAP-10a
program The opening dinner at NETS-2011 featured a keynote address by Dr. Glen Schmidt, test engineer for SNAP-10a - the only fission reactor the US has flown in space. SNAP-10a overcame many significant engineering challenges on the way to mission success; we need to take a close look at past programs to understand both how and why things were done a certain way as we endeavor to achieve flight for a fission system once again.
Dinner at the National Museum of Nuclear Science and Technology Keynote Address: Dr. Harrison "Jack" Schmitt, Apollo 17 Astronaut, former U.S. Senator (NM) Keynote Address: Reflections on the Apollo Program At a special evening event on Wednesday, February 9, conference participants were treated to a presentation by Dr. Harrison "Jack" Schmitt, former US Senator for New Mexico and Apollo 17 astronaut - the last man (and the only scientist) to walk on the moon.

III Panel
Session: Pu-238 Supply and Production Session Summary: The panel session on Pu-238 supply and production was overwhelmingly popular among attendees – overflowing the session room. Four presentations were provided by the panelists, describing:
Questions from the floor were many and varied, demonstrating high interest and engagement among the meeting attendees. Topics covered during the Q/A session included safety, production byproducts, varying (increasing) production quantity, consideration of alternate approaches/isotopes, and relationships to stakeholders and political influences. Panelists: L. Dudzinski, NASA Headquarters - NASA Radioisotope Power Systems Needs A. Caponiti, DOE Headquarters - Pu-238 Production - Restoring a Reliable Supply R. Wham, Oak Ridge National Laboratory Future Supply of Pu-238 for Radioisotope Power Systems (full paper by R. Wham included in conference proceedings) S. Johnson, Idaho National Laboratory Recent Radioisotope Power Systems Efforts, ... Track II Panel Session: Fission Power and Propulsion Session Chair: L. Mason, NASA Glenn Research Center - Introduction Session Description: The history of space fission power systems has included many program starts and stops, and only one U.S. flight system launched into space (see SNAP-10a discussion in the Opening Dinner presentation by Dr. Glen Schmidt). The object of this panel session was to tap the knowledge of several "grey beards" who have participated in these programs in order to learn what steps should be taken to secure a successful outcome. The session included short presentations by the panelists on establishing mission pull, essential building blocks for a successful program, the relationship of government and industry, and lessons from our past (see links below to download). Following the presentations, the audience joined in a lively discussion with the panelists to debate the best path forward for space fission power. Panelists: J. Nainiger, Alphaport Inc. How to Establish A Mission Pull S. Bhattacharyya, RENMAR Enterprises Inc. What are the Critical Building Blocks S. Bailey, Bailey Engineering and Management Inc. Government and Industry Working Together A. Weitzberg, Consultant What We Can Learn from Our History Additional Papers/ Presentations Study of a 100kWe Space Reactor for Exploration Missions E. Cliquet, J-M. Ruault (CNES Launchers Directorate,Evry, France), J-P. Roux, L. Lamoine, T. Ramee (AREVA TA, Aix en Provence, France), C. Poinot-Salanon, A. Lokhov, S.
