Developing energy resources that are environmentally friendly and free from high-level radioactive waste is especially important for next generation, particularly in Korea where underground resources are lacking. Fusion energy development is of great significance pursuing one of the alternatives that is less dependent on fossil resources.

 

The fusion energy development in Korea is based on the Fusion Energy Development Promotion Law, and the KSTAR project plays a very important role in resolving the critical issues required for future fusion reactor development and in raising the human resources capable of the research. The KSTAR project has several unique features (extremely low error field, versatile in-vessel control coils, 2D advanced imaging diagnostics, and high efficient long pulse capable heating system) to achieve a high performance steady-state operation research vision. The KSTAR

 

The KSTAR project started in 1995, achieving the first plasma in 2008, and has shown a lot of remarkable results for 10 years’ operation. In particular, KSTAR achieved the long pulse (over 70s) H-mode discharge with confinement equivalent to ITER (betaN ~ 1.8) and suppressed Edge Localized Mode (ELM) crash robustly up to 34 s using n=1 Resonance magnetic Perturbation (RMP). In addition, progress in fundamental physics interpretation on the turbulence and instability due to advanced diagnostics system and modeling studies.

 

In order to explore the plasma confinement and instability at higher confinement (betaN > 3.0), heating systems are under upgrade (NBI heating 5.5.MW à 12 MW, ECCD system 1 MW à 6 MW), and Divertor and current driving system will be upgraded also around in 2021 to develop a steady-state scenario for K-DEMO.

We acknowledge the contribution and collaboration to KSTAR from national and international collaborators. This work is supported by Ministry of Science and ICT (MSIC) of Korea under KSTAR project.
