  2. The TWG’s play a key role in the ARIES Pathway Study Decision to commercialize fusion Parametric trade studies External advisory committee 2 1 TWG’s: Power management Tritium management Plant operations T W G R&D needs and priorities Design requirements 3 4 Tokamak line of R&D Experimental power reactor 5 ARIES-AT Demo ARIES-AT Nuclear tokamaks ITER ARIES Study Outcomes: 1. Guidelines for fusion development 2. Sensitivity study results 3. R&D planning document 4. Preconceptual design requirements 5. Preconceptual design report Non-nuclear tokamaks Other R&D and facilities

  3. Our goal is to translate advisory committee recommendations into design requirements and an R&D plan Mission Customer Needs Requirements Present Database Reactor Conceptual Design Issues & R&D Needs R&D Implementation The “ARIES Process”

  4. The Power Management TWG has been populated • Mark Tillack (R&D plan leader) • René Raffray (design requirements leader) • Don Steiner • Said Abdel Khalik • Siegfried Malang • Plasma expert tbd

  5. Mission Statement • Demonstrate fusion energy production and utilization, including: • power and particle handling • extraction of power core high-grade heat • power conversion • nuclear performance of in-vessel and ancillary equipment

  6. Pinjected Systems approach to power management In-vessel components Plasma Blanket Pn Cooling Pfusion First wall, PFC’s Prad,chamb frad Pa 1-frad Divertor frad,div Prad,div Pdiv Pcond 1-frad,div Power conversion Creating fusion energy… … for the production of electricity

  7. R&D Needs and Priorities Subgroup – Approach and Tasks – • Document the current status of R&D • In the US • Worldwide • Characterize the R&D gaps • To a power plant • To a CTF/Experimental power reactor • Develop R&D plans and options

  8. Technical Design Requirements Subgroup – Approach and Tasks – • Establish scaling metrics and goals • Define device characteristics • Define device parameters • Define operating scenarios and test program • Exploration of parameter space • Demonstration of controllability • Etc.

  9. TWG Schedule Jun 2007 Sep 2007 Dec 2007 Mar 2008 Jun 2008 Sep 2008 TWG planning UAC mtgs Formulation of requirements Definition of requirements Conceptual design activity Conceptualdesign process R&D existing status and needs R&D plans/options R&D planning Final reports Documentation
