Defence, nuclear & energy technology Medium

भारत ‘अंतर्राष्ट्रीय ताप-नाभिकीय प्रायोगिक रिएक्टर (International Thermonuclear Experimental Reactor)’ का एक महत्त्वपूर्ण सदस्य है। यदि यह प्रयोग सफल हो जाता है, तो भारत का तात्कालिक लाभ क्या है?

Read this question in English

India is an important member of the 'International Thermonuclear Experimental Reactor'. If this experiment succeeds, what is the immediate advantage for India?

(a) It can use thorium in place of uranium for power generation · (b) It can attain a global role in satellite navigation · (c) It can drastically improve the efficiency of its fission reactors in power generation · (d) It can build fusion reactors for power generation

उत्तर और व्याख्या · explanation in English

Answer: (d) यह विद्युत् उत्पादन के लिए संलयन (फ्यूज़न) रिएक्टरों का निर्माण कर सकता है

ITER is an experiment to show that nuclear fusion, the joining of light atomic nuclei as in the Sun, can work at power-plant scale. Every ITER member shares the experimental results and intellectual property, so if it succeeds, India can build its own fusion reactors for power.

  • ✓ (d) ITER is meant to prepare the way for future fusion power plants, and members share its results and intellectual property. Fusion power reactors are the natural next step for India.
  • ✗ (a) Using thorium as fuel belongs to India's fission reactor programme; ITER is a fusion project and does not test thorium.
  • ✗ (b) Satellite navigation depends on satellite systems (such as India's own navigation constellation), which have nothing to do with a fusion experiment.
  • ✗ (c) Fusion is a different process from fission. A fusion success would not by itself make fission reactors more efficient.

Remember · ITER (in France; members China, EU, India, Japan, Korea, Russia, USA) tests nuclear fusion; the payoff is knowledge to build fusion power plants.
