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.
