Consider the following statements regarding China’s Experimental Advanced Superconducting Tokamak (EAST): I. EAST is a tokamak-based nuclear fission device that uses high-energy neutrons to split heavy nuclei and generate power. II. The recent breakthrough by EAST relates to achieving sustained electricity generation from nuclear fusion for China’s national grid. III. EAST operates on the principle of magnetic confinement fusion and is designed to study plasma behaviour at extremely high temperatures. IV. The breakthrough achieved by EAST has already made fusion energy commercially viable for large-scale power plants. How many of the above statements are correct?
