About KSTAR
Click below for information on KSTAR:
The mission of the KSTAR project is to develop a steady-state-capable
advanced superconducting tokamak to establish the scientific and
technological bases for an attractive fusion reactor as a future
energy source.
- To extend present stability and performance boundaries of
tokamak operation through active control of profiles and
transport.
- To explore methods to achieve steady state operation for
tokamak fusion reactors using non-inductive current drive.
- To integrate optimized plasma performance and continuous
operation as a step toward an attractive tokamak fusion reactor.
- Fully superconducting magnets
- Long pulse operation capability
- Flexible pressure and current profile control
- Flexible plasma shape and position control
- Advanced profile and control diagnostics
- Extend advanced tokamak research to high performance and
steady state operating regimes.
- Contribute techniques for successful steady state physics
operation of ITER.
- Compare advanced tokamak physics results with those from
superconducting stellarators and spherical tokamaks.
Successful construction and operation of KSTAR will advance
Korea's scientific and technological capability in significant ways.
