The second Unit of Kakrapar Atomic Power Station (KAPS-2 — 220 MW) attained Criticality (initiation of controlled self-sustaining nuclear fission chain reaction in the reactor) today (Monday) at 02:22 hrs, after completion of Renovation & Modernisation (R&M) works, encompassing En-Masse Coolant Channel Replacement (EMCCR), En Masse Feeder Replacement (EMFR) and other safety upgrades. This task was completed about three and half months ahead of schedule.

Collaborators in Renovation

In this endeavor, Nuclear Power Corporation of India Limited (NPCIL) and Nuclear Fuel Complex (manufacturer of coolant channels)played important role.  Bhabha Atomic Research Centre (BARC) and various vendors/contractors provided their expertise to achieve this extraordinary task. Many other organisations and workers of KAPS rose to the occasion for this achievement. The approach to criticality was undertaken after meeting all the stipulated regulatory requirements. Very soon various tests will be conducted. Testing of connection to the grid and increase in power level to full power as per laid down procedures and regulatory clearances will also be done .
