Summary of NCSX System Integration Team (SIT) Meeting of Monday, November 10, 2003

1.  FY-04 Schedule Risks

Brad summarized the schedule risks in the stellarator core area:

• Risk #1: Modeling of the MC winding forms. This is holding up the critical.
  
  • Don’t yet have a model that all designers, manufacturers, and analysts can work with.
  • Both suppliers are unable to use it.
  • (It was later decided to halt the suppliers’ work and provide them a new model developed by Tom Brown. This has reportedly been done and the suppliers will soon be authorized to resume work.)
  • Even if the Type C prototype work gets back on track, it is not clear that Tom’s model solves all MCWF modeling problems. It may not be a permanent fix.
    
• Risk #2:  Adequacy of MC analysis plans, once a model is in place. (See 11/3 minutes.)
• Risk #3:  Machining cost uncertainties
  
  • Have the machining subs analyzed our parts in enough detail to identify risks so they can be addressed ahead of time?
    
• Risk #4: Not getting the VV ports requirements defined in time.
  
  • Lots of progress with WBS 3 lately, but will requirements be established when needed by WBS 12 in order to stay on schedule?
    

Corrective actions:

• There is another Pro/E expert potentially available at ORNL. If  Brad thinks this person could contribute to resolving the modeling problems, Brad should secure his services.  ACTION: Brad.
• Determine whether and how critical ORNL FY-04 design jobs could be speeded up with additional resources. (Jim, Brad)
• Should there be a Pro/E modelers’ expert workshop to develop a plan for coming up with a permanent solution? ACTION:??
• Are analytical resources needed to augment Steve Chae? ACTION:??
• Get the machining subs spun up now to look at our designs and provide some feedback. ACTION: Brad work with Phil.
  

2.  Budget and Work Plans for FY-04
Ron and Hutch distributed and led a discussion of FY-04 plans.
Actions/Responsibilities

• Address resource overload issues (Wayne, Brad)
• Could some of Chrzanowski’s fab work be done outside instead of at PPPL, anticipating overloads? (Wayne follow up with Chrzanowski)
• Identify WBS 1 tasks for Art Brooks (Brad, provide to Wayne).
• Cryostat and Base (WBS 17) work will be authorized. (Ron follow up with Gettelfinger)
• Modular coil handling fixture and GPS system procurements will be authorized so we can start getting experience. (Wayne follow-up with Raftopolous.)
• Discuss management reserve plans with Greg and PPPL Management (Hutch, Ron)
  

3.  C-Site Power Option Study
Mike Zarnstorff is the job manager. ACTION: Mike prepare a WAF.

4.  Next SIT Meeting: Monday, November 17, 2003
