  2. Alignment Data PF5( A&B and U&L) Installed location Current Location Measurement accuracy

  3. Alignment PF5 Lines- original location, dash lines-lower Symbols- current location

  4. Overall assembly

  5. Overall-mid plane

  6. Pedestal/Centerstack - ongoing

  7. PF4/5 support 6 new columns 6 Old locations at vessel VEM interface to clamp

  8. TF Support Rings Springs

  9. Tf-Links 4” OD Tube x .25” thk Insulation Springs @10,000 LBF/ins

  10. Preliminary Analysis-no radius rod envelope load • No Radius rod, • Similar behaviour at K = 19.85 KlbF/ins from Han’s chart • Deflection ~ .35”, Max von mises ~ 50 Ksi at Al to cu interface

  11. Preliminary Analysis- radius rod @12,000 lbf/ins Deflection ~ .31”, Max Von Mises ~ 36 Ksi

  12. Overall status • Ongoing to mature PDR Radius rod spring ~ 10,000 Lbs/ins PF4/5 radius support-thermal issues Interface to center stack, lids, spokes • Refinement from matured PDR-others material optimization stress and stress concentration weight Fabrication Installation
