Notes from 3/11/2011 Meeting:
Calc Spreadsheet
Updated spreadsheet attached.  


Outer TF Leg ring support analysis   (Rogoff) (see VGs)
Validation analysis of the final design for the outer TF leg support ring was completed 
and indicates stresses are acceptable per the NSTX structural design criteria.  Bolts 
can be cold worked 316SS, bolts will require tensioning to 13.2 kips or torquing to 8.8 
kip - in.

Progress on Busswork Modeling (Khodak) (see VGs)
 FEA modeling of the final design for the TF, PF and OH Busswork was completed and 
meshed. The models will now be used to validate the final design.

PF2 and 3 Supports Analysis (Titus) (see VGs)
Took another look at the stress in the fasteners and supports on the PF 2 and 3 coils using an 
approximation of 6 evenly spaced supports.  Stresses in the coils, insulation, fasteners, supports 
and welds look acceptable.  This still needs to be reconciled with the analysis run by Smith that 
indicates problems in the fasteners and supports.
