• Modeling the MCWF: We have made progress but haven’t demonstrated a model that works for all 3 types and fits together without interferences. Until then we are pursuing three parallel approaches: Dave Williamson’s, Tom Hargrove’s, and Tom Brown’s.   When one of these approaches works, that will be the appropriate time for a modelers’ workshop to settle on the path forward for the project. The timescale is forecast to be ~first week of December.
• Constructing analytical models from the CAD model:  John followed up with H.M.Fan and learned that this is still a problem area, even with the progress made in modeling. Needs continued attention.
• Manufacturer feedback on potential machining issues: this needs to be an agenda item for the December tour of the MCWF suppliers. We should ask for presentations of their machining simulations. ACTION: Hutch follow up with Phil H.  Phil plans to hold a meeting before the trip to set the specifics of the agenda. Provide input to Phil.
• Vacuum vessel design and interface issues. Discussions at this meeting and thereafter turned up several vacuum vessel design issues which require prompt resolution:
  
  • Accommodating the ICRF antenna feeds.
  • Accommodating the internal trim coil leads.
  • Accommodating inboard supersonic gas injectors.
  • Increasing minimum plasma-wall distance (reportedly shrunk to 1.4 cm).
  • Re-segmenting the vacuum vessel (what problem does this solve?)
  • Baking to 350 C.
    

Meetings are planned for Dec. 2 (edge physics) and Dec. 3 (engineering) to address some of these issues.
ACTION: Mike follow up with R. Majeski to ascertain latest ICRF feed requirements and solution options.

• A draft PBR issues disposition plan with preliminary assessments was distributed. The issues are more straightforward than the PDR issues, requiring relatively little analysis or design to support decisions.  ACTION: Hutch/Wayne develop disposition recommendations.
• John has taken an initial cut at responding to the EIR recommendations. ACTION: John/Hutch/Ron resolve.
• Proposed schedule:
  
  • Finalize disposition plans by Dec. 12.
  • Finalize changes to the cost & schedule baseline (including contingencies) by Dec. 19.
  • Updated resource-loaded schedule and ECP by Jan. 9.
  • CD-2 ESAAB, week of Jan. 26.
