The Unit-3 of Kakrapar Atomic Power Project (KAPP-3 – 700 MWe), located at Kakrapar, Gujarat achieved its first criticality (controlled self-sustaining nuclear fission chain reaction for the first time) on July 22, 2020 at 0936 hrs.

 

Hon’ble Prime Minster tweeted a Congratulatory message on the occasion:
Congratulations to our nuclear scientists for achieving criticality of Kakrapar Atomic Power Plant 3! This indigenously designed KAPP-3 reactor is a shining example of Make in India. And a trailblazer for many such future achievements.

 

A Historic Development
KAPP-3 is a first of its kind, indigenous 700 MWe Pressurised Heavy Water Reactor (PHWR). It is indigenously designed by Indian scientists and engineers. The components & equipment for the reactor have been manufactured by Indian industries and the construction and erection was undertaken by various Indian contractors. This is a major shining example of Make in India endeavour in the high technology arena.

 

The reactors are designed and constructed to the highest safety and quality standards comparable to the best in the world. The indigenous 700 MWe PHWRs have advanced safety features like steel lined inner containment, Passive Decay Heat Removal system, Containment Spray system, Hydrogen management Systems etc.

 

The fuel loading of the reactor core was completed by mid-March 2020. Thereafter, many tests and procedures were carried out during the lockdown period following all COVID 19 guidelines. The tasks could be achieved with the excellent coordination and cooperation among NPCIL, DAE units and various Central, State & local authorities.

 

Further Steps
Experiments / tests will be conducted and power will be increased progressively. Thereafter it will be connected with the western grid. The unit will be the 23rd nuclear power reactor of the country.

 

KAPP-3 is a trailblazer, as it is the first in a series of sixteen (16) indigenous 700 MWe PHWRs which have been accorded administrative approval and financial sanction by the Government and are at various stages of implementation.

 

NPCIL has seven more reactors, KAPP 4 (700 MWe), RAPP 7&8 (2X700 MWe), KKNPP 3&4 (2X1000 MWe) and GHAVP 1&2 (2X700e MWe) under construction. These reactors are expected to be completed and achieve criticality progressively from next year.
