Subject:
20060322 NCSX weekly update
Greg, Jeff, and Barry,
I will be on vacation this
Thursday and Friday, so on Jeff’s suggestion we will forego this week’s telecon.
Contact Ron in my absence if there are any
questions.

NCSX Weekly Update of
03/15/06
1. Modular Coil fabrication
(PPPL)
C-1 Coil
- The C1 was moved from the
autoclave to the final assembly station for removal of the mold, installation
of permanent clamps, and warm testing.
- Current forecast is to
complete the C1 coil by 3/27/06, or 4 days ahead of schedule for the Level II
milestone scheduled for March.
C-2 Coil
- Winding clamp
adjustments were completed and a dimensional scan was performed. The scan
showed a need to correct a few of the clamp settings. Securing of the lacing
strips will start immediately thereafter.
- We forecast completion of
the C2 coil by 4/29/06, versus our Level III schedule target of 4/17 in the
performance-measurement baseline. The delay in C2 completion does not impact
the critical path but management focus is to complete winding station
operations on C2 to make way for C4.
C-3
Coil
- A dimensional
scan of the C3 coil is in progress.
- We forecast completion of
the C3 coil by 6/12/06, versus our Level III schedule target of 6/5/06 the
performance-measurement baseline. The delay in C2 completion does not impact
the critical path but management focus is to expedite winding station
operations.
2. MCWF procurement (Energy Industries of
Ohio)
MCWF summary status:
15 poured to
date
4 in foundry operations
8 in machining operations
3
delivered.
Machining operations (Major Tool and
Machine):
C-4
- The final machining of the
poloidal break was completed and the part moved to final inspection. We expect
they will meet the project’s scheduled delivery date of March 31. It may ship
this coming weekend.
C-5
- The C-5 completed the first
of the five remaining machining steps on the 5-axis U5. The project’s
scheduled delivery date is May 4.
A-1
- The A-1 is in the first
operation of two on the 3-axis Mitsu-40. The project’s scheduled delivery date
is June 8.
A-2
- The poloidal break has been
cut and the shim welded in place. The project’s scheduled delivery date is
July 13.
A-3
- The A-3 is in roughing
operations on the Lucas 40T.
B-1, A-4, and C-6
- The A-4 was shipped by
MetalTek after completing foundry operations.
- The A-4, B-1, and C-6 are
at MTM, awaiting machining.
Foundry operations (MetalTek International):
A-5
- The A-5 returned from MQS
needing only a few repairs, which were then completed. A final dimensional
scan was completed. After stress relief and final LP inspection, it will be
ready to ship to MTM.
A-6
- The A-6 returned from MQS
following RT.
B-2
- The B2 was shipped to MQS
for initial RT.
B-3
- The B-3 casting is
undergoing initial processing steps such as heat treat and
grinding.
B-4
- The B pattern is being set
up in preparation for pouring the B-4.
3. VVSA procurement (Major Tool
and Machine)
- VVSA #1: The dimensional
scan data sent last week are being analyzed by the NCSX team. They show
out-of-tolerance conditions in 15-20% of the data points, but analyses of
potential assembly and performance impacts are still in progress. This is to
determine which areas must be corrected. Because of the importance of
minimizing the amount of rework in order to minimize schedule and technical
risks, the analysis is taking additional time. To further minimize project
risks, MTM has suspended processing of areas that may need to be corrected,
but are continuing with tasks in unaffected
areas.
- VVSA #2, processing of VVSA
#2 is largely on-hold pending resolution of VVSA #1 dimensional issues.
Applying the lessons learned on VVSA #1 is necessary to reduce risks on
#2.
- VVSA #3, the sector
has reached the front of the queue for the DSI machine where the port holes
will be bored. That operation will start immediately after completion of
maintenance operations on the DSI.
