Summary of NCSX System Integration Team (SIT) Meeting of Monday, September 19, 2005

1.    Management and Project Control

• FY-06 estimate reviews for WBS 12, 13, 18, 8 were scheduled for this week. WBS 15 & 17 will be after SOFE.
• Estimate growth must be managed in a way that does not involve steep contingency draw-downs. Plan is to draw contingency as it’s used, keeping it at about 25% or higher.  Candidate savings to offset estimate growth will be identified.
• An issue is how to handle coil interface hardware, a ~$1M item previously overlooked and therefore not currently budgeted. Responsibility: Hutch
  

2.    Targeted Schedule Risks

• Job 1414, Twisted Racetrack Coil testing. Hope to finish high-power testing soon.
• Job 1403, Modular coil design and drawings.  Designer staffing will be augmented to provide more schedule contingency.  Need to decide between using ORNL or PPPL resources early this week.  Action: Brad.
• Job 1411, MCWF Fabrication.  Major Tool still forecasts shipping C1 to PPPL Sept. 23; we expect delivery in September. We are maintaining daily contact on schedule status and plans for final inspection and test.  Responsibility: Phil.
• Job 3101, Magnetic loops physics requirements (Mike Z.)
  
  • Flux loops. Expect to require ~200-220 loops. Requirements will be delivered by Sept. 23. Physics should not delay delivery of physics requirements (number and geometry) to tackle engineering tasks such as rounding of the corners.  Physics should interface with Mike Cole.
  • Diamagnetic loops.  Ex-vessel loops are likely needed (potentially new scope). Configuration needs to be determined. Is it possible to use modular coils’ co-wound loops? Lower priority than flux loops, since the latter are now schedule-critical.
    
• Job 1203, VV design. Last week’s FDR (Part I) showed design is going in the right direction but incomplete in significant ways. Further discussion by the SIT came to the following conclusions.
  
  • Heating & cooling tubes: Adopt flexible tubes as the baseline because we had no bids on the hard tubes and the flex tubes are expected to be significantly cheaper to procure and install. The performance may be less, and needs to be quantified ASAP via testing and/or analysis. The support pads may need to be closer together to compensate for lower performance.
  • Insulation material: Adopt nanogel as the baseline, since we only require 150 C and nanogel is good to 250 C. Replace it with something else (t.b.d.) later when we upgrade to 350 C..
  • Procurements: A bill of materials is needed to package the procurements and provide visibility of all hardware. Action: Ron take the lead in drafting a bill of materials for WBS 12.
  • Interfaces: a meeting will be held of all WBS managers having interfaces with WBS 12 to work interface issues. Responsibility: Wayne.
  • Priorities for procurement and implementation:  the heating and cooling tubes have priority because they are needed first.
  • Completing the Title II design. We need to wrap up the loose ends and determine what is needed in the way of assembly drawings and other documentation. We need to decide how to subdivide the remaining reviews. Responsibility: Brad.
    
• WBS 18, Field Period Assembly.  Station 1 (VV Prep Station) FDR was successful. Need to decide how many we need. Depends on budget and schedule considerations.
  

4.  Next SIT Meeting: Oct. 10.
