Charge |
1. Are all
required analyses complete and formally checked and adequate to establish
that the proposed design is feasible and meets established design criteria?
2. Are the drawings and documentation
adequate to support the procurement and/ or manufacturing process,
installation, and ready for sign-off?
3. Is the plan for installation of the
trim coils compatible with the machine assembly plans?
4. Is the Product Specification (C-SPEC)
complete and satisfactory? Are the interfaces adequately defined?
5. Is the Work Planning form current,
and have the applicable requirements been satisfied?
6. Have the chits from the PDR been
resolved?
7. Are updated cost and schedule
estimates available? |

Summary of Results
|
The final design of
the NCSX trim coils was reviewed. Coil drawings were complete (but not
yet signed off), and included all aspects of the structural design and
assembly of the two coil configurations used to make up the 48 coil
set. Drafts of the system specification (CSPEC) and Statement of work
(SOW) were made available at the time of this FDR, but had not yet
undergone a general project review. All drawings and specifications
have subsequently been reviewed and approved. A summary of the approved
system requirements was presented as well as the results of the
completed analysis of the structural design of coils and mountings for
both electromagnetic and thermal loads. Material specifications and
tolerances were reviewed. The result of the testing of the proposed
welding of coil structures was also presented. The proposed schedule and
expected costs were presented and discussed.
This FDR follows a
comprehensive review of the preliminary design (held on 3/24/08), and
the resolution of the chits from that PDR were reviewed.
There were 7 chits
recorded during this final design review, with suggestions concerning
the review of specifications, the thermal performance of the coils in
LN2, the analysis of the effects of these coils on other systems,
welding techniques, winding geometry/techniques, mounting fastener
details, and the possible need of a dedicated system Failure Modes and
Effects Analysis (FMEA). The review committee concurred with all chits,
and agreed that this review was successful pending resolution of the
chits. |
