KSTAR project


KSTAR is the worldclass superconducting tokamak developed and constructed by domestic technology. KSTAR operation will establish the knowledge-base for fusion science and operation techonology. KSTAR will help Korea to lead fusion technology 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 campaigns carried out every year since the first plasma achievement in July 2008. In 2018, the KFE performed its 20,000th plasma experimental shot.
