KSTAR Project
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.
