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

  1. A.It can use thorium in place of uranium for power generation
  2. B.It can attain a global role in satellite navigation
  3. C.It can drastically improve the efficiency of its fission reactors in power generation
  4. D.It can build fusion reactors for power generation

Correct answer

D. It can build fusion reactors for power generation

Explanation

The correct answer is D, it can build fusion reactors for power generation. ITER is an experiment to prove that nuclear fusion can work as a large-scale energy source, and every member shares its technology. Being built at Cadarache in southern France, ITER is a tokamak, a doughnut-shaped machine that uses powerful magnets to hold hydrogen plasma, deuterium and tritium, at about 150 million °C so that the nuclei fuse and release energy, as in the Sun. Its members are the European Union, China, India, Japan, South Korea, Russia and the United States; India joined in 2005 and supplies parts such as the cryostat. If ITER succeeds, India gets full access to the know-how for building its own fusion power plants. Option A is wrong because using thorium is the aim of India's three-stage fission programme, not of fusion. Option B is wrong because satellite navigation is the field of NavIC and has nothing to do with ITER. Option C is wrong because ITER studies fusion, not ways to improve fission reactors. Exam tip: ITER = fusion, tokamak, Cadarache (France); India a member since 2005.
