Kakrapar Atomic Power Plant, Unit-3 (KAPP-3), India’s first 700 MWe (megawatt electric) pressurized Heavy Water Reactor (PHWR) with innovative features attained criticality at around 9:36 am on July 22, the Department of Atomic Energy said. A nuclear reactor attains criticality when every nuclear fission event releases a sufficient number of neutrons to sustain an ongoing series of reactions or a self-sustaining chain reaction. He said in a twwet: "Congratulations to our nuclear scientists for achieving criticality of Kakrapar Atomic Power Plant-3! This indigenously designed 700 MWe KAPP-3 reactor is a shining example of Make in India. KAPP-3 is located at Kakrapar, Gujarat, where already two 220 MWe PHWRs (KAPS-1 & KAPS-2) are in operation and another 700 MWe PHWR (KAPP-4) is under advanced stage of construction.
