Notes from 2/9 Meeting:
The WP numbers related to each calculation have been added to the calculation spreadsheet 
attached.
 
Update on the Lid with crown reinforcement   (Smith) (see VGs)
Provided an update of the lid with a crown reinforcement requested by Titus to reduce bending 
moments on the G10 hub connection.  Question: Is the reinforcement needed? Ali to add the 
moments from the lid into the model to determine if G10 stresses warrant the addition of a 
crown above the lid.

Upper Center Stack TF/Hub Assembly  (Zolfigari) (see VGs)
The G10 hub connection between the lid and TF bundle had been modeled with the latest design models. 
 The displacements look ok but stresses around the fastener holes look high.  Still need to add friction 
coefficients which should improve stresses.

Seismic analysis update  (Titus) (see VGs)
The seismic analysis is ready for checking.  The analysis indicates the only modifications required are the 
clips around the leg radial outriggers held down by 8- 5/8" Hilti's per leg.
