Review Title Final Assembly Plan Peer Review
Date 15  April  2004
Cognizant Engineer Mike Cole
Responsible Line Manager Brad Nelson
Review Board Chairperson Erik Perry
Review Board Members Wayne Reiersen, Tom Brown, Steve Raftopoulos, Geoff Gettelfinger
Invited Attendees Hutch Neilson, Larry Dudek, Jim Chrzanowski, Dave Williamson, Paul Goranson

Charge Access the NCSX stellarator core final assembly plan with respect to the following:

1. Do the motions of the field period assemblies and vacuum vessel spool pieces required for final assembly of the stellarator core maintain adequate clearances among and between all the components?

2. Are the assembly tooling requirements reasonable and achievable?

3. Are appropriate provisions made for metrology and in-process sensors (i.e. motion proximity, etc)?

4. Are the assembly requirements defined for the base support structure? (plan includes PF pre-placement, motions, accuracy, VV port extension provision, etc.)

5. Is the plan documented in the final assembly procedure?

Summary of Results

A potential assembly sequence was presented as well as an analysis of minimum clearances between the vacuum vessel spool piece and clamps.  Fourteen chits were generated, the most significant ones being the need to develop a leak checking technique for the vacuum vessel field welds and the need to demonstrate clearance among and between all of the components during assembly. 

*Once all of these chits have been closed-out, another peer review should be held with a review board that includes several persons who have managed the construction of large devices.
