Les Waganer mentioned the upcoming October project meeting planned for Bethesda, MD. Al Opdenaker is making the arrangements with the Doubletree Hotel.

ARIES Technical Efforts

Chuck Kessel and Lane Carlson have been working on the 4-corners configuration definition, but they are held up by the lack of a better characterization of the power flow for ARIES studies. Mark Tillack is working on that topic. Lane suggested holding off until the power flow algorithms are available and then he will issue a preliminary strawman set of cases, perhaps by the October meeting. Laila El-Guebaly wishes to have the strawmen cases prior to the meeting to prepare a code output validation presentation. Chuck K. said that even one point would be sufficient.

Minami Yoda reported progress on their parameter analysis of the divertor heat transfer coefficient, back pressure and power flow simulations. She will have sufficient data to make a presentation on this subject at the October meeting.

Siegfried Malang noted that he and Xueren Wang have been working on both divertor and first wall design solutions. On the divertors, he feels they have solutions to accommodate a maximum heat load of 15 MW/m2. On the first wall, they have analyzed solutions in excess of 2 MW/m2 steady state heat loads with plastic deformation, but they have not analyzed the creep condition yet.

Laila El-Guebaly has been investigating the auxiliary power algorithms with Chuck Kessel and hopes to report on that at the October meeting. The 3-D neutronic analysis is on hold pending more detailed designs. She is working on three orals and two posters for the upcoming TOFE meeting.

Les Waganer mentioned he has been working on developing a methodology to scale plant availability from the usual 10th of a kind plant to earlier plants such as one of a kind and the first of a kind. He will make presentation on this subject at the meeting.

Rob Goldston is concerned about the assumptions on the thickness of the power scrape off layer and the maximum power deposited on the divertor.

Alan Turnbull mentioned that he discussed profile control at the May meeting and he continues to work on that subject as well as edge stability.

Mark Tillack said that he is continuing to pursue attendees at the Plasma Edge Town Meeting to provide papers documenting their work, with minimal success. He hopes to complete this documentation shortly.
