Summary of WBS 4 Cost Review Meeting of Wednesday, June 18, 2003

Attendees were S. Ramakrishnan, L.Dudek, M. Williams, C. Neumeyer, R.Strykowsky, W.Reiersen, M.Zarnstorff, and H.Neilson.

Raki's updated estimates were discussed. They are based on the CDR requirements, updated to waveform data issued by Wayne in April, 2003. The estimate was $7,542k, an increase of $899k over the current baseline. We discussed the reasons for the increase and possibilities for cost reduction. The following decisions and assignments resulted:

1. WBS 432, D-to-C-site DC Systems: Raki proposed a 2-wire design for all circuits. However, some of the circuits can be stacked (not the modular coils) and still satisfy voltage test requirements. This would reduce the number of cables. It was decided to modify the stacking to the extent possible to reduce Day-1 cost. ACTION: Raki revise the estimate.

2. WBS 433, D-Site DC systems. New firing generator and fault detector circuits were proposed, which would update to modern technology and improve equipment protection. However, it was decided that the project would live with the existing circuits through first plasma. An upgrade after first plasma was recommended as a benefit to both NCSX and NSTX.

ACTION: Raki revise the estimate.

3. WBS 412, Experimental AC power. Apparent estimate growth has already been resolved. ACTION: Raki revise the estimate.

4. WBS 446, Ground fault monitor. It was agreed to remove it from the baseline, as recommended by Raki.

5. WBS 46 (new), FCPC Modifications.  It was agreed that these costs should be budgeted under WBS 4.

ACTION: Raki follow-up with J.Chrzanowski on estimates.

ACTION: Ron find out if this scope is already budgeted somewhere, e.g., in WBS 7.

6. It was decided that further MIE scope reductions should be pursued by exploring reductions in the number of Day-1 circuits. The physics team (N. Pomphrey) is looking for acceptable equilibria.

ACTION: Mike Z. and physics team develop candidate design basis equilibria with simpler circuits.

ACTION: Raki develop simpler configuration once requirements are received.

7. ACTION: Raki submit updated estimates to Ron by Monday June 23. (Except #6 which will take longer.)

Possibilities for accelerating WBS 4 scope were discussed. It was decided we should try to expedite the design work in order to position the project to be able to perform construction work whenever money becomes available to do so. Additional resources needed:

1. Electrical design support this year. ACTION: Mike W. follow up.

2. $35k of M&S to fund structural design contract. (probably next year)

3. $400-ish K of M&S to install the towers. (Next year)
