Q. The Experimental Advanced Superconducting Tokamak (EAST) nuclear fusion reactor is recently in news was developed by which country?

[A] Russia

[B] Australia

[C] Britain

[D] China

Answer: D

Scientists around the world have been trying for decades to recreate the unfathomable power of the sun here on Earth, and a team in China has managed to best our local star. Not for very long, though. 

  • The team operating the Experimental Advanced Superconducting Tokamak (EAST) managed to heat the reactor’s internal plasma to 100 million degrees Celsius (212 million Fahrenheit).  
  • That’s six times hotter than the sun, but it doesn’t have any net power generation. In stars, hydrogen fuses into helium, and eventually into heavier elements.  
  • The fusion process releases large amounts of energy, and the byproducts of fusion aren’t radioactive.  
  • The only nuclear power we’ve managed to utilize on Earth is fission, which requires dangerous radioactive materials and comes with the risk of a reactor meltdown.
