  • Criticality means that a reactor is controlling a sustained fission chain reaction, where each fission event releases a sufficient number of neutrons to maintain an ongoing series of reactions. This is the normal state of nuclear power generation. Hence option (c) is the correct answer.
  • Nuclear reactors use uranium fuel rods—long, slender, zirconium metal tubes containing pellets of fissionable material to create energy through fission. Fission is the process of splitting the nuclei of uranium atoms to release neutrons that in turn split more atoms, releasing more neutrons.
  • Gujarat Kakrapar-3 Atomic Power Plant (KAPP-3) attained criticality in 2020. It is India’s first 700 MWe unit, and the biggest indigenously developed variant of the Pressurised Heavy Water Reactor.
