NCSX Procurement Update of 5/24/05

1. MCWF procurement

• Machining of the C-1 casting (MCWF#1) continues. The rough machining down to the 0.25-in. stock envelope is completed, Machining of the poloidal break has started and is about half complete.
  

• X-ray inspection of the C-2 casting (MCWF#2) is almost complete. We expect to hear about the results when we visit this week.
  

• Preparations for pouring the A-1 (MCWF#3) casting continue at MetalTek, and also continue to be a challenge due to its size and some of its geometrical features. After some difficulty, they finally succeeded in removing the pattern from the mold. They now expect to pour this week.
  

• Solidification modeling for the B pattern (the last one) has completed its third iteration.
  

• A project delegation will visit MetalTek on May 25-26 to discuss progress, schedules, and documentation issues.
  

2. VVSA procurement

• Fabrication of the 60-degree weld fixture continues. The entire fixture was assembled last week, but two of the supports were found to require some re-work.
  

• Fabrication of the panels continues. They expect to start welding panels together this week.
  

• The technical representative, Mike Viola, will visit Major Tool this week.
