    Previously, the EU and Japan inaugurated JT-60SA, the world's largest and most advanced Tokamak fusion reactor in Japan and pledged support to advance fusion research for International Thermonuclear Experimental Reactor (ITER).

    • Tokamak is a machine for controlled thermonuclear fusion with a toroidal shape, similar to a doughnut.

    About Nuclear Fusion

    • A process by which two light atomic nuclei combine to form a single heavier one while releasing massive amounts of energy. 
      • In nuclear fission, on the other hand, large atomic nuclei are split into smaller atomic nuclei to release energy.
    • Most fusion reactors use a mixture of deuterium and tritiumhydrogen atom isotopes that contain extra neutrons.

    About ITER

    • ITER is a global scientific partnership between China, Europe, Japan, India, the Republic of Korea, Russia and the US.
      • It’s currently under construction in France.
    • Objective: To prove the viability of fusion as an energy source.
    • It will be the largest Tokamak device to test magnetic confinement to produce fusion energy.
    • ITER has been designed for high fusion power gain with about 10-fold return (expressed as Q ≥ 10), i.e., ratio of heating input power to thermal output power.
      • Current record for fusion power gain in a Tokamak is Q = 0.67 by European JET facility in the UK.

    ITER-India

    • India formally joined the ITER Project in 2005.
    • ITER-India is the Indian domestic agency, a specially empowered project of the Institute for Plasma Research (IPR)
      • IPR an aided organization under Department of Atomic Energy, Government of India.
    • ITER-India is responsible for delivery of ITER packages such as Cryostat, In-wall Shielding, Cooling Water System, Cryogenic System, Ion-Cyclotron RF Heating System, etc
