NCSX Weekly Update of 11/30/05

1. Modular Coil fabrication (PPPL)

C-1 Coil

• The ground insulation and lacing strips were installed.  The winding clamp side bars have been installed for both sides A and B. These control the final dimensions of the winding pack and are positioned in locations computed for each clamp based on the measurements for that winding form.
• The lower leads for side A have been set into position, and the winding of conductor has started. It is anticipated that both sides A and B will be wound before the year-end holidays.
• The winding teams are working 2 shifts per day, and worked several shifts over Thanksgiving weekend to improve the schedule.
  

2. MCWF procurement (Energy Industries of Ohio)

Machining operations (Major Tool and Machine):

• The C-2 winding form completed 5-axis machining operations.  It is now on the coordinate measuring machine undergoing final dimensional inspections.  The project’s expectation is that it will ship around Dec. 10.
  

• The C-3 casting continues making good progress through 3-axis machining operations. The poloidal break has been machined.
  

• The C-4 is in rough machining on the Lucas machine.  The first side was finished last week and they have started on the second side.
  

• The C-5 was released for shipment from MetalTek last week after reviews of foundry documentation were completed, and arrived at Major Tool on Monday 11/28.
  

• The A-1 casting is at Major Tool.
  

Foundry operations (MetalTek International):

• The A-2 is undergoing weld upgrades.
  

• The A-3 completed its initial radiographic testing and is back at the foundry. Inspection results are still being evaluated.
  

• The B-1 casting was heat treated and is in grinding operations.  A dimensional scan by 3D ScanCo is scheduled for Dec. 5.
  

• The C mold has been assembled and the C-6 casting is expected to pour tonight.
  

3. VVSA procurement (Major Tool and Machine)

• Welding of ports into the first 120-degree segment continues. All of the large, custom-shaped ports are welded in and smaller, circular ports are in the process of being welded in.
  

• The second 120-degree segment is on the milling machine, where the port holes are being cut.
  

• Fabrication of the fifth 60-degree half-segment continues.
  

• Fabrication of the large ports for segments 2 and 3 continues.
  

• Fabrication of the first spacer is almost complete.
