What the examiner wants

Trace India's fusion energy journey, state its contributions to ITER, and explain what ITER's success would mean for global energy.

ExplainMake clear how and why it happens: causes, process, and an example for each point.

Demand-wise check

  1. 1India's programme: Institute for Plasma Research (Gandhinagar), ADITYA tokamak (1989), SST-1 steady-state superconducting tokamak (2013)≈35 words
  2. 2ITER contributions: India joined in 2005; supplies about 9% in kind — cryostat (the world's largest stainless steel vacuum vessel, made by L&T), in-wall shielding, cooling water system, cryolines, ion cyclotron and electron cyclotron heating systems, diagnostics, power supplies≈35 words
  3. 3Implications: abundant low-carbon baseload power, little long-lived waste, no meltdown risk, energy security; but timelines are long (first plasma delayed to the 2030s)≈35 words
