Summary of NCSX System Integration Team (SIT) Meeting of Monday, July 19, 2004

1.    WBS 1 Re-planning activity and CPI/SPI improvement (Wayne)
Re-planning input for the major work packages has been received. A top-down schedule is being developed toward the milestone of starting to wind the first production modular coil in mid-January. There are three major activities, all of them close to the critical path:

• Twisted racetrack coil fabrication, testing, and evaluation.
• Fabrication of the pre-production prototype winding form for the first coil.
• Design of and fabrication of components for the winding assembly.
  

An ECP is being developed to bring the performance measurement baseline in line with the new plans. In addition the ECP must address the declining performance indices for the July close. Actions regarding the re-planning ECP (Bob, Ron):

• Provide budget for the extended analysis and testing activities related to fracture life.
• Provide budget for the C-site power supply option design study.
• Check that proposed changes will keep indices above 0.9.
• Be prepared to present the draft ECP, or at least the elements of the ECP, to Greg by Friday, July 23.
• Determine what flexibility exists to transfer FY-04 funds to ORNL, should the plan require it.  (Jim, Brad, Hutch, Ron)
  

2.   Prototype MCWF processing (Wayne et al.)
We discussed a proposal by Wayne to terminate processing of the prototype MCWFs once the production proposals are received. It was argued that continued work on prototypes thereafter would be of little value but high cost. Brad recommended finishing the poloidal break.  He pointed out that they could be used for assembly practice (e.g., testing the C-C mating) if completed. Phil stated concerns that the fracture properties testing effort is going slowly, and neither supplier has submitted complete properties data. We concluded the following.

• The project’s preferred course is to direct the suppliers to terminate processing of the prototypes when they submit their proposals. This would free up significant budget (100’s of k$) which would help to cover other project cost problems.
• We don’t need them to ship the prototypes to us. The winning team could use them for further manufacturing development later, at their option or the project’s.
• We need to get agreement with DOE and research any procurement issues.
• Action: Phil discuss with Procurement.
• Action: Hutch discuss with DOE.  Follow-up 7/19 p.m.: the Federal Project Director does not support stopping work on the MCWF prototypes at this time. We will re-visit the question when the proposals arrive.
  

3.   Metrology critical issue (Wayne)
Wayne announced the project’s metrology core team:  Art Brooks will be project’s expert resource, consistent with his technical assurance responsibilities. Mike Cole will lead design efforts. Steve Raftopoulos will lead field implementation.  All will attend the W7-X Metrology Workshop in August. They have been invited by the W7-X team to serve as reviewers.

4.  Next SIT Meeting:  Monday, July 26 at 11:00 a.m. EDT.
