Abstract :
The vertical stability of the ARIES-I reactor design is analyzed with the NOVA-W, PSTAB, and TSC codes. A growth rate of ~5.7 s-1 is predicted for a vacuum vessel which is positioned behind the scrapeoff, first wall, and blanket (0.7-m inboard and 0.9-m outboard thickness), and which acts acting as a passive stabilizer. A reactive power of ~2 MVA would be required for active feedback coils located outside of the TF (toroidal-field) coils (~3 m beyond the plasma in the equational plane) to correct a 50-mm vertical displacement of the magnetic axis. A multipole-expansion technique used in the TSC analysis is also used to examine options that minimize stored energy
