Les Waganer noted that the next ARIES project meeting will be held at General Atomics, San Diego, CA on 15 December 2009 (all day) and the morning of 16 December 2009. Alan Turnbull will be out of town until the meeting and will not be able to serve as the host. Mark Tillack has offered to serve as the point of contact with GA on all arrangements. GA has increased security requirements and all non-US citizens need to contact Alan or Mark to initiate the paperwork. It would be beneficial for all attendees to alert Mark if they plan to attend to expedite the badges.

Mark Tillack is developing plans for upcoming ARIES town meeting on edge physics modeling. He has been contacting potential attendees, but no date has been finalized. It will probably be held in San Diego. Mark will provide an update at the December meeting.

Laila and Farrokh will present at the December meeting a summary of the recent ISFNT meeting they attended.

Farrokh Najmabadi said that the future meeting with Al Opdenaker to discuss ARIES budget and future plans is on indefinite hold due to pressing matters at OFES. The 2010-2012 proposals have been received by OFES.

ARIES Technical Efforts

Siegfried Malang and Xueren Wang have been collaborating on protection schemes for the first wall to accommodate a steady-state heat flux of 1 MW/m2 with peaking or off normal spikes of 2 MW/m2. Xueren continues to analyze and improve the finger and plate design for the divertor protection.

Mark Tillack noted that he is trying to obtain UCSD students to help on the ARIES technical analysis, but the specific areas of effort are not defined yet as it depends on the students and skills available.

Farrokh Najmabadi told the group that he has been working with Chuck Kessel on the Systems Code to develop four distinct plasma and power core cases that represent the corners of the design space of interest. Zoran Dragojlovic continues to work on improvements on the Systems Code in the area of new costing algorithms and power core geometry definition. If Zoran is in San Diego that week, he will present his status on the systems code.

Laila said that she has been coordinating with Lee Cadwallader (INL), Brad Merrill (INL) and Neill Taylor (ITER) to identify the safety-related components for ARIES-DCLL power plants. The 1996 DOE reports on Safety of Magnetic Fusion Facilities and the ITER team have defined the safety-related components in ITER and the like. Laila feels this will help define our recommended safety-related components for ARIES power plants to use in future ARIES studies.

Laila told the group that neutronics experiments on He-cooled LiPb mock-ups at ENEA, Italy have decreased the uncertainties in tritium production for LiPb from 6% to 3%, so the TBR margin can be reduced in future tritium breeding calculations.

Laila said E. Diegele (EU) mentioned at the ISFNT-9 symposium that the EUROFER ferritic steel can be qualified for fusion applications within 10 years, if IFMIF is available. Also, A. Kohyama (Japan) outlined the ongoing plan to develop, test, and qualify SiC/SiC composites for fusion use in 10 years.
