About KSTAR

KSTAR is the worldclass superconducting tokamak developed and constructed by domestic technology. The knowledge-base for fusion science and operation technology will be established through the operation of KSTAR. A world-leading position in fusion technology will be attained in the era of commercial fusion power plants.

KSTAR is the world's next-generation superconducting tokamak nuclear fusion research device for the development of fusion energy. Developed and constructed using Korean technology, KSTAR has been in full operation with excellent outcomes from experimental campaign carried out every year since the first plasma achievement in July 2008. In 2018, the NFRI performed its 20,000th plasma experimental shot.
