Les Waganer had queried the team for the best dates for the next project meeting to be held in the January 20-22, 2009 time frame. All voting team members could attend all dates except for one person who had difficulty with January 20 date, thus the team decided to hold the meeting on Wednesday, January 21 (full day) and the morning of Thursday, January 22. The meeting will be held in San Diego.

Rene Raffray mentioned that the High Heat Flux Divertor workshop to be held on December 10-12 at UCSD is on track. He expects about 30-36 attendees.

Previously, the upcoming conference call dates were selected, but the planned conference call on December 12 conflicted with the High Heat Flux Divertor workshop meeting to be held at UCSD. Therefore, that date was moved to Tuesday, December 16th at the normal time. A subsequent call will be held as planned on January 6, Tuesday, (primarily to preview the FESAC TRL presentations being prepared by Tillack and Weaver).

The FESAC meeting is still planned to be held in Washington, DC, on January 13-14, 2009 and may cover the TRL presentations. This is still tentative as the agenda has not been finalized or issued.

Mark said that he has not received any further comments or changes to the interim report and will post the report on the ARIES website without further notice, (which he has done).

Report of November 2008 FESAC meeting

Dale Meade and Tom Weaver attended the meeting, as a FESAC Committee member and observer, respectively, and provided information and insight about the topics discussed.

Dale Meade said the November 2008 FESAC meeting agenda is provided on the FESAC web site. Prof. Stewart Pager, who was the previous FESAC Chair, has been replaced by Dr. Martin Greenwald of MIT. Prof. Riccardo Betti was named as FESAC Vice-Chair. In addition, there are several other new members. Dr. Gene Nardella thought that the OFES budget would be in the continuing resolution process through March 09. There was some speculation that the ITER budget might be increased due to the economic stimulus package. The OFES Draft Strategic Plan in response to Congress's call for a bold credible plan for fusion energy was to be discussed in this meeting, but there was no consensus of the content of the draft plan so its presentation was delayed, to the January 09 meeting. The organization chart for the Research Needs Workshop (ReNeW) planning process was discussed. Of particular interest to the ARIES team is the Harnessing Fusion Power theme which is chaired by Dr. Wayne Meier and Dr. Rene Raffray. The Plasma Materials Interface theme is chaired by Dr. Mike Ulrickson and Dr. Rajesh Maingi. The Toroidal Alternates Panel (TAP) was discussed. Dr. David Hill is the leader of this panel. The concept advocates provided the information on their main issues and planned objectives, but the FESAC members crafted and defined the alternates' objectives (goals and value of achieving goals) to insure commonality and uniformity of approach and metrics.

Tom Weaver said noted that Congress seemed to want a bold, credible plan to achieve fusion energy, not fusion science. However DOE seems to be more aligned with a science-based program.

Report of October 2008 IAEA meeting

Dale Meade attended the October 2008 IAEA meeting that celebrated the 50th year anniversary of magnetic confinement fusion research. Dale gave a short synopsis of MFE advances for the last 50 years. The progress and future of ITER was discussed. Dale said there are preprints available through IAEA. There was a talk by a China representative that provided a timetable for their future DEMO and commercial MFE plans. Dale provided links to the Official meeting web page and a few talks on the FIRE web site , Fusion Meetings.S

Preview of December 2008 HHF conference

Rene Raffray said that the planning for the high heat flux conference is on schedule. There are about 32-36 people from the US, EU, and Japan that will attend. The topics will include the current state of the HHF divertor materials and technologies, what (and when) needs to be accomplished, and specific plans to accomplish the technology maturation. To this end, Mark Tillack will have a presentation on the TRL process to plan and measure the technology maturation.

Status of Improved ARIES Systems Code

Zoran Dragojlovic noted that he continues to improve and baseline the systems code against published results on prior ARIES final designs. He is also assembling a journal paper to be published in Fusion Engineering Design Journal. The paper will cover the code structure, capabilities, modeling algorithms used and results and parametric trends obtained.

Impact of SiC Insulators in Liquid-Cooled Blankets on Tritium Breeding Ratio

Laila El-Guebaly is working with UCLA researchers to assess the impact of using the SiC insulating layer surrounding the liquid metal coolant channel on the tritium breeding ratio. The 1997 UW results agree well with the UCLA recent results. The UCLA results indicated a significant increase in the magnet heating when using 20% dense SiC insulating layers. Laila will check the impact of SiC inserts on the magnet heating and fluence, complete the breeding analysis, and present the results at the January ARIES meeting.

Inputs to the Harnessing Fusion Power Panel

Rene Raffray mentioned that he and Wayne Meier are working on the planning for Harnessing Fusion Power five panels. Each panel will have a separate leader and panel members addressing that topic. Rene said he would distribute the panel names and leaders to the ARIES team so that each person could contact the leader and contribute to the panel topic

Status of Helium-Cooled Divertor Engineering

Xueren Wang said that he continues to work on the He-cooled divertor to increase the heat and particle flux capabilities. He is optimizing and finalizing the plate-type, T-tube and the two-heat-flux zone divertor configurations with both thermal-mechanical and thermal-fluid methods, for both transient and steady state solutions. Rene and Xueren submitted two papers on this subject to TOFE and SOFT conferences.
