Starlite Conference Call Minutes, Wednesday, 1 Feb 1995

PARTICIPANTS (by organization): Sze, Billone, Ehst, Wong, Sager, Herring, McCarthy, Bathke, Waganer, Bromberg, Hofer, Flynn, Steiner, Miller, Mau, Tillack, El-Guebaly


The minutes for the 18 Jan 95 conference call minutes have been distributed.

The preliminary agenda for the next Starlite meeting at UCSD was distributed by Waganer prior to the call and the team discussed each area in detail. Adopted changes were incorporated and Waganer reissued the list shortly after the meeting. Tillack put the revised agenda on the WWW home page.

A question was raised as to the level of the distribution list of the quarterly progress reports. It felt that the distribution should be to a limited set of the fusion community due to the working and evolving nature of the reported results. M. Tillack will confer with B. Dove to determine intended purpose and the appropriate distribution list.


Task Results:

Task 1 - L. Waganer reported sending out a reminder to the FICUS members for comments. M. Tillack will determine if the mailing to the UAC members has been accomplished.

Just before the conference call, Waganer distributed a strawman list of the quantified top level requirements. The list was reviewed and commented on. There was a lot of discussion regarding which requirements should be top level and those to be subordinate, especially those associated with the COE. The intent was to initiate the discussion of the requirements' numeric value (and it worked!). Waganer will incorporate the conference call decisions into the requirements list. At the meeting, we should reach a consensus on the entire quantified requirements list.

The need to establish the evacuation plan as a requirement was strongly debated. The ability to quantify the economic benefit of no evacuation plan was discussed. G. Hofer agreed to compare two fission plants that had either minimal or extensive licensing difficulties to determine the range of times for the licensing procedure - will present the data to Miller for incorporation in his model. R. Miller will continue to explore methods to quantify the Safety, Licensing, and other non-economic parameters.

The group felt we should be given more direction as to the nature and timing of Starlite program milestones. Waganer said a detailed Starlite program mission and schedule are in work and hopefully will be discussed at the meeting. He expressed hope that DEMO I major system trade studies could be concluded by July 1995 followed by trades for Demo II. This would enable the initiation of the conceptual design of the Demo I near the end of 1995.

Task 2. - R. Miller explained some more about his enhanced techniques to display and analyze the COE elements. He has developed two dimensional plots to interpret the multidimensional effects.

Task 3 - T. Flynn reviewed his RAMI Top Level Requirements. Nuclear plant capacity factors, and availability for the nuclear plants have improved 12% since TMI while the values for fossil plants remained virtually unchanged. The reason is related to improved reliability of BOP systems. He is also working with C. Wong on a system diagram in order to develop a detailed plant reliability estimate.

Task 4. - D. Steiner reviewed the progress of the L&S group. He mentioned the 1994 tasks results (progress) were finalized and forwarded to Waganer. Don should bring electronic copies to the meeting.

Greg Hofer reported two reports are being readied for publishing while the third is being reviewed. He continues to work on the tritium regulation and licensing.

Steve Herring spoke of several meetings on the establishment of the Fusion Safety Standards. He will present data on this topic at the meeting. Steve briefly discussed the evolving goals, that were similar to those charts given by D. Steiner for incorporation in the Top Level Starlite requirements.

Task 5A. - Dave Ehst reported that he needed to talk to C. Kessel to proceed on equilibrium data - hoped to get in touch with him in Japan. Would try to get results for presentation at the meeting. He also discussed the physics figure of merit progress for all physics options. Would not expect completion for a 1/2 year to a year.

C. Bathke reported he was working on the J-Solver to reformat data for the EQDISK data. Will have the interface finalized soon. Will have some results to discuss at the meeting. B.J. Lee has been working on the radiative mantle.

C. Bathke also reported that he would not likely have enough supporting data to generate strawman results for the reverse shear and the low aspect ratio devices. The prior LANL reports had engineering data but this data is not completely relevant to the current low aspect ratio ideas. The plasma shape and triangularity are different. It was mentioned that Martin Peng should be contacted and C. Bathke agreed to ask for his inputs and support.

The need to have engineering data and engineering support was discussed at length. C. Bathke needs specific data to build a computer model to the same detail as the ARIES series. This would not seem to be possible within the time and manpower constraints. Instead, Chuck may present a set of critical issues to be considered.

Task 5B - M. Tillack expressed concern that no alternate power core design concepts have been proposed. Time has been allocated in the meeting to present such designs. If any team personnel wishes to propose an alternate design concept, M. TIllack should be informed so he can to coordinate this activity and include a preliminary discussion/planning session at the engineering meeting.

The material assessment activity was discussed. It was expressed that the pros and cons of copper usage seem to be highly debated The group was trying to balance the trends to higher heat and neutron fluxes (which demand materials with higher capabilities) with the requirement for low waste materials.
