India's first indigenously developed nuclear power plant unit begins operation at full capacity

In News
  • In a significant development, India's first indigenously developed nuclear power plant unit in Gujarat has started operations at full capacity.
About KAPP
  • The Kakrapar Atomic Power Project (KAPP) had initiated its commercial operations on June 30, 2023, but initially operated at only 90 percent of its capacity. On August 31, 2023, the plant finally achieved its full operational potential.
  • The Kakrapar Nuclear Power Plant is a testament to India’s capability in developing and operating nuclear power facilities entirely on its own.
  • The Nuclear Power Corporation of India Limited (NPCIL) has been at the forefront of this endeavor.
  • A PHWR is a nuclear power reactor, commonly using unenriched natural uranium as its fuel, that uses heavy water (deuterium oxide D2O) as its coolant and moderator.
  • PHWR technology was started in India in the late 1960s with the construction of the first 220 MWe reactor, Rajasthan Atomic Power Station (RAPS-1).
  • State-owned Nuclear Power Corporation of India Ltd (NPCIL) had awarded the reactor-building contract for both KAPP-3 and 4 in 2010.
  • The 700 MWe PHWRs have advanced safety features like steel lined inner containment, passive decay heat removal system, containment spray system, hydrogen management system, among others.
  • The ‘passive decay heat removal system’ can remove decay heat (released as a result of radioactive decay) from the reactor core without requiring any operator actions.
  • This is on the lines of similar technology adopted for Generation III+ plants to negate the possibility of a Fukushima-type accident that happened in Japan in 2011.
