Subject: Summary of NCSX SIT Meeting of 7/10/06
Summary of NCSX System Integration Team (SIT) Meeting of Monday, July 10, 2006

1.   Safety items: follow-up on issues from recent ISM review

• Hazard controls in JHA and procedures.
  
  • There is a proposal to incorporate the JHAs into our manufacturing procedures as a means of controlling the JHAs and keeping the JHAs and procedures consistent. This would keep them in sync, but a concern was expressed that it would make it more cumbersome to change the JHA. The flexibility to change the JHA in the field in response to changing needs is considered vital. It was decided to hold off on the proposal to incorporate the JHA into the procedure, and give it further consideration.
  • The Lab is re-visiting the JHA procedure.
    
• NCSX procedures: VPI procedure has been revised. New autoclave access procedure has been written.  The autoclave operations procedure was to have been revised to include references to the access procedure and improved safety notes. What is the status/plan?  Larry
• Formal tracking of ISM review responses.  Wayne will identify items for which NCSX is responsible and propose disposition. Coordinate with Jerry Levine, et al., who are preparing the Lab response.
  

2.  Management Items

• Status of pending work scope issues, discussed in draft memo of 6/29/06.
  
  • MC flux loops: cancelled.  Use to help offset WBS 3 cost variances.
  • Magnetic Alignment will not be incorporated into the MIE project plans.  Requests for research-supported measurements of inductances at various sub-assembly stages will be accommodated to the extent possible without impacting the schedule.
  • Trim coils on the MC shell: it is argued that the MC shell may be the only practical location for trim coils, but there are no plans for such coils. A side discussion is planned to better understand the requirements and options.  Action: Hutch
  • Additional cold testing:  Wayne is leading analysis effort to support decision by July 31.
  • Third winding fixture: Larry is obtaining the cost estimates, and Wayne is performing process simulations needed to support a decision by July 31.  Some of the fixture drawings need to be updated.  Larry will check with E. Perry regarding installation costs.
    
• Cost performance improvement
  
  • We are launching an initiative to improve cost performance in the remainder of FY06.
  • Monthly cost variances have been in the –$300k to –$400k range and monthly CPI has been 0.7-0.8.  Proposed goal is  to improve monthly CV to >–$150k and CPI to >0.90.
  • A plan was requested by the Director’s Office. It is needed to improve DOE confidence that the project can be completed within the present baseline.  A plan has been documented by Ron and circulated to the SIT.  Action: SIT review and comment on the cost performance improvement plan.
    

3.    Risks

• C1 repair:
  
  • Mike W. reported that the lead block cover was removed and the resistance to ground (measured with a 9V DVM) immediately increased to a high value.  Subsequent meggar check at 7.5 kV measured 15 GOhms. These findings confirm the previously suspected cause and location of the fault.
  • A peer review of the proposed repair procedure will be conducted on Tuesday.
  • A decision needs to be made on whether to also modify C2, which passed a 7.5 kV meggar test. The decision will await repair of C1 and Chrzanowski’s return from vacation.
    
• Analysis of C1 test results
  
  • Displacement monitor results compare reasonably well with analysis, under consistent support assumptions.
  • Strain gauge results are still not well understood.
  • Cooldown results suggest issues with the cryogenic system including the cryostat, that may need to be addressed for the system to be installed on the machine. Some testing and development may be desired.
  • Goal is to complete the analysis and decide on future testing by July 31.  Responsibility: Wayne.
    

4.  Next SIT Meeting: July 24
