Subject: Summary of NCSX SIT Meeting of 3/27/06
Summary of NCSX System Integration Team (SIT) Meeting of Monday, March 27, 2006

1.   Management items

• ETC Update in preparation for Lehman review.
  
  • Some input was received by 3/24 deadline, but much still outstanding. Ron will schedule management reviews, starting with VV and MC design this week. Ron
    
• Safety Items.
  
  • Project was recognized by State of NJ for no away-from-work lost-time cases in 2005.
  • Manufacturing Facility Project Hazard Analysis has been updated by Larry.  Action: Larry to distribute to SIT (done).
  • Recent safety-related violations (construction tape, radiation work permit) at PPPL were discussed.  We are susceptible to  violations or even accidents resulting from lapses in attentiveness to rules. Consequences adverse to the project can result. Procedures need to be reinforced with staff. All
    

2.    Risks

• VVSA dimensional non-conformances (Wayne)
  
  • In-process dimensional data provided by Major Tool were analyzed by the engineering team last week. Assessment if the part (VVSA #1) were to be completed with these conditions:
  • No problem with field period assembly.
  • There is encroachment into the plasma region in local areas near the bullet cross section on the inboard side. If allowance is made for weld distortion during assembly (re-installing the port or making up the field joints), then the encroachment is about 0.30 in. over a few square inches.  If no allowance is made for assembly distortion, only a few points are out of tolerance.
  • The flange is still being measured, however it is known to have problems.
  • We are trying to clarify our acceptance criteria. We will communicate them to Major Tool ASAP.
  • Our assessment of the in-process data is that, if the completed part were to have the current dimensional conditions, it would be unacceptable. Some repair of the flange, at least, will be required. This assessment will be communicated to Major Tool.
    
• Type A Modular coil parts.
  
  • Brad is pushing to finish the Type A lead blocks, cladding, and chill plate drawings. They are starting to get released now.  
  • Larry is developing contingency plans in case parts procurement is delayed.  Chill plates and cladding can be built in-house if necessary.  The A coils can be delayed in the sequence as long as there are C coils to work on.
    
• Modular coil inter-coil shear handling (Wayne)
  
  • Engineering is studying solutions which involve adding more flange bolts on the inboard side. The goal at this stage is to find one solution that will work.  Other approaches may also work.  A presentation and recommendations will be made in the next few days.
    

4.  Next SIT Meeting: t.b.a.
