The KSTAR project will make critical contributions to the world
fusion research and development program.
It will:
Extend advanced tokamak research to high performance andsteady state operation regimes.
Contribute techniques for successful steady state physics
operation.
Compare advanced tokamak physics results with those fromsuperconducting stellarators and spherical tokamaks.
Utilize KSTAR as “International Fusion Collaboratory” !!
