  1. Summary and Closing Remarks Farrokh Najmabadi UC San Diego Presentation to ARIES Program Peer Review August 29, 2013, Washington , DC

  2. Nature of Power Plant Studies has evolved in time. • Concept Exploration (< 1990) • Limited physics/engineering trade-offs due to lack of physic understanding (the only credible vision was a large, expensive pulsed tokamak with many engineering challenges). • Concept Definition ( ~ 1990-2005) • Finding credible embodiments (Credible in a “global” sense). • Better physics understanding allowed optimization of steady-state plasma operation and physics/engineering trade-offs. • Development of high-performance blanket concepts. • Concept Feasibility and Optimization (> 2010) • Detailed analysis of subsystems to resolve feasibility issues. • Definition of R&D requirements (e.g., material properties) • Trade-offs among extrapolation and attractiveness in order to guide R&D.

  3. Summary of ARIES-ACT Research • ARIES-ACT study is re-examining the tokamak power plant space to understand risk and trade-offs of higher physics and engineering performance with special emphasis on PMI/PFC and off-normal events. • Detailed physics analysis with modern computational tools are used. Many new physics issues are included. • The new system approach indicate a robust design window for this class of power plants. • In-elastic analysis of component including Birth-to-death modeling and fracture mechanics indicate a higher performance PFCs are possible. Many issues/properties for material development & optimization are identified. • Many engineering improvements: He-cooled ferritic steel structural ring/shield, Detailed flow paths and manifolding to reduce 3D MHD effects, Identification of new material for the vacuum vessel … F. Najmabadi, ARIES Peer Review closing, 29 August 2013 (3/6)

  4. ARIES-ACT Publications (49 papers) ARIES-ACT1 final report to be published as a special issue of Fusion Science & Technology (8 articles) 15 papers in TOFE-19 (published in FS&T vol. 60) 12 papers in TOFE-20 (published in FD&T vol. 64) 13 other articles in FS&T, FED, SOFE, etc. These papers can be downloaded from the ARIES web site.

  5. Some ARIES Town Meetings

  6. National ARIES Program has been a high-leverage research effort High Quality of Science: Detailed and in-depth analysis is necessary to make scientific progress. High-Leverage Research: Integrated design & analysis beyond current experiments identifies key R&D Issues. Community input and consensus: An environment is created for fusion scientists to investigate fusion systems together. Team members bring in the latest information from R&D program. State-of-art analysis, innovation, and high-leverage issues are readily transferred back to the R&D program. Interaction with other disciplines: Impact of latest development in other scientific fields on fusion systems are evaluated. Impact on Education: Approximately 2/3 of the research is performed by universities (UCSD, U. Wisc., GIT). Seven students were supported by this activity last year. A high-leverage niche on the international fusion program. It is recognized internationally as a credible driving force towards an attractive end product and influences world-wide fusion research.
