Material Cost Validation
- Stainless Steel Basic Structure -
PPPL asked Boeing (L. Waganer) to develop a preconceptual design and cost estimate for the FIRE tokamak support structure
Support structure system includes flexible gravity supports, assembly structures, and radial and vertical restraint structures
Material is mostly 304 or 316 stainless steel
Radial compression rings and center tierod column are laminated structures to reduce eddy currents
