Abstract
Design optimization of JT-60SU has been done for a steady-state
advanced operation. A transport code simulation indicates that a fully
non-inductive reversed shear plasmas with fractions of 70% of the
bootstrap current and 30% of beam driven current can be sustained
for more than
1,000s without any additional control. Investigations have been progressed
on MHD stability , vertical positional stability and dynamics of the
vertical displacement events . Significant progress has been achieved
in the R&D of
superconducting wires, low induced activation material (Fe-Cr-Mn
steel). A design improvement has been made in TF coils to reduce a local
stress on radial disk. Dynamic behaviors of the tokamak machine have been
analyzed at emergency events such as an earthquake.
