Analysis Reports          
PF Coils          
NCSX-CALC-132-01 Thermal Hydraulic Analysis of PF4/PF5/PF6 Chrzanowski (Dahlgren) The thermo-hydraulic analysis of PF4, 5, & 6 for worst case I-sq x T establishes the minimum pressure and flow requirements for the LN2 coolant system. R-0 approved 2/22/2008  
NCSX-CALC-132-02 Stress Analysis of  PF4/PF5/PF6 Chrzanowski (Dahlgren) The Myatt consulting analysis was checked and results were in reasonable agreement with the current PF4/5/6 analysis.  Basis assumptions of clamped boundary conditions and material properties in the analysis agree with the coil support design and published property data. R-0 approved 2/22/2008  
Backup Analysis Files Preliminary analyses in support of final calculations Kalish Preliminary calculations and studies performed to support evolution of the design and formal calculations    
None performed - Need to do a global one for the entire Stellarator Core.
Other Notes          
Some of the current requirements changed since the original analysis was completed but those changes were small compared to the large design margins.  F. Dahlgren did the original thermal analysis and then repeated it with his FCool run.  We do still need a final FCool run for PF5 and PF6.  The stress calculations for the structural analysis that included the PF coils can be referenced as a check of Lenís original analysis.  It would take a memo noting the differences in assumptions and requirements and how the large design margins compensate for any smaller discrepancies.  It should be noted that  the project needs to be reminded that a final analysis needs to be performed of the whole system to determine maximum allowable temperature differentials to determine the final operating parameters.
