Subject: Summary of NCSX SIT Meeting of 5/22/06
Summary of NCSX System Integration Team (SIT) Meeting of Monday, May 22, 2006

1.   Management items

• Budget for the rest of FY-06 is very tight. Plans have been scaled back to keep from over-spending. We reviewed the plans and priorities. We need to re-visit whether planned transfer of $175k from PPPL to ORNL is still optimum.  Action: Jim assess impact if transfer amount were $100k instead of $175. By 5/30.
• A number of potential spending needs, which are currently unbudgeted, are under discussion. The following were discussed by the SIT:
  
  • Magnetic alignment: A method for aligning coils based on inductances has been proposed. Its purpose is to mitigate technical risk associated with the limitations of mechanical alignment methods. The cost of developing the technique and building the equipment has been estimated to be at least $100k (ROM). Between now and June 30, continue analyses of issues and develop a more accurate cost estimate. (Mike Z.)  Decide on further expenditures around the end of June.
  • Additional coil winding fixtures:  Discussed at a separate meeting on 5/22.  Winding operations are currently staff-limited, but additional fixtures (and associated staff increases) may be needed to meet the coil winding schedule.  Options range from a holding fixture ($15k) to a full coil winding station ($70k). Fixture preparation would need to start in FY-06 to be ready in early FY-07, in time to make a meaningful impact on the schedule.  However, no FY-06 funds have yet been identified. (Hutch, Ron)
  • Cold testing beyond C1:  The baseline is to only cold test C1, but there are arguments and review recommendations to increase the scope of testing. We will re-visit these after C1 is tested. (Hutch)
  • Trim coils:  The amount budgeted for trim coils can provide a basic two-coil system just outside the PF coils, but that may not be the optimum location. It may be preferable to mount them on the modular coil shell (~1,000 A-turns), but they would be trapped once the machine is assembled. Therefore, it might be necessary to install a full system while the machine is being assembled, but there is no budget for it in the MIE project. (Hutch, Wayne, Mike Z.)
  • Coil resistance measurement.  It was proposed that we should re-instate the provisions to make coil resistance measurements prior to a shot. It has been proposed to eliminate this as one of several scope cuts. However, a resistence measureement is critical to verify that the coil has cooled back down since the previous pulse.  Resolutlion: do at least the minimum to ensure we have this capability. (Wayne)
    
• Safety:
  
  • Tour safety in manufacturing facility needs to be addressed. Provide information and training for tour guides. Restrict tour hours. Clearly demarcate tour routes and stay-out zones. Action: Hutch work with Dudek, DeLooper et al.
  • PPPL safety forum stressed link between mistakes/lapses and accidents.  Since mistakes can’t be eliminated, have to work to make the system robust against isolated lapses and mistakes.
    
• Diagnostic organization:  Brent Stratton succeeds Dave Johnson as WBS 3 manager. Larry Dudek is the RLM.
• April cost performance report. Cost and schedule variances have grown, mostly attributed to the same jobs as for the past several months. WBS 14 design has shown some improvement.  WBS 3 variances are getting worse. Action: Hutch follow up with Brent.
  

2.    Risks

• C1 cold testing schedule.  Progress in last few days has kept apace of schedule.  Strain gage test results are consistent with expectations. Kevin Freudenberg is delivering a new displacement monitor for installation on the test coil. (Wayne)
• C3 and C4 schedule risks.  C3 is due to finish pre-VPI ops. June 6, but is forecast to be several days (≤l week) late. C4 is due July 20, but is losing some shifts this week while C2 is being potted. Action: Larry try to recover schedule if possible
• Modular coil shear plate tests. All of the hardware has been fabricated. We are awaiting the studs so they can be installed to simulate what would be done during coil assembly at PPPL. The studs should be in very soon. (M. Cole)
