Kaiga unit sets world record among PHWR for operating uninterrupted for 895 days

The Kaiga Atomic Power Station (KAPS) has set a new world record among pressurised heavy water reactors (PHWRs) with one of its units operating uninterrupted for 895 days as of October 25, 2018. 

The Unit-1 of Kaiga Generating Station (KGS-1) in Uttar Kannada district of Karnataka  had set a national record for continuous operation of 766 days.

The previous record of 894 days of continuous operation was held by a unit of pickering nuclear generating Station(PNGS) in Canada.

KGS-1 now stands first among PHWRs and second among all nuclear power reactors in the world in terms of continuous operation. The unit has been operational since May 13, 2016. KGS-1 is an indigenous PHWR, powered by domestic fuel. It commenced commercial operations on November 16, 2000.

As per the AEC Chairman, at present, there are nine (9) nuclear power reactors at various stages of construction in India and twelve (12) more nuclear power reactors have been accorded administrative approval.

NPCIL presently operates 22 reactors with a capacity of 6,780 MW.
