COLLABORATION ACCOUNTABILITY RESPECT EXCELLENCE / CARE

Both KSTAR and ITER are essential routes for DEMO and commercial road development- KSTAR is the cradle of fusion technology independence.

  • Before ITER operation, advanced levels of plasma experiment, control, and analysis capabilities are to be secured. KSTAR is the cradle of R&D, human resource development, and education of underlying technologies for fusion.
    • Participating in ITER does not guarantee the establishment of fusion technology.
  • ITER's prime goal is to demonstrate fusion energy from the engineering point of view, provided that fundamental technologies such as plasma physics are secured.
    To realize such basic technologies, KSTAR is more than essential.
    • With the technologies attained by both KSTAR and ITER, the construction and operation of the DEMO will be carried out, and the construction of a Korean fusion power plant in the 2040s becomes feasible.
