KGS-1 sets a new benchmark in continuous operation


KGS-1 world record continuous operation

Kaiga Generating Station, Uttara Kannada, Karnataka


Indigenously designed, developed and operated Unit-1 of Kaiga Generating Station (KGS1 - 220 MW) in operation since May 13, 2016, surpassed the earlier world record of 940 days continuous operation held by Heysham-2 Unit-8 of the United Kingdom on December 10, 2018.The unit has completed 962 days of continuous operation till 31.12.2018, registering higher than highest continuous operation record world over.


During its continuous run of 962 days, the unit generated about 5 billion Units of electricity at a Plant Load Factor of about 99.3%. The unit was shutdown at around 2300 hrs on 31.12.2018 to take up inspections and maintenance activities. It will be restarted after carrying out various maintenance activities, inspections and regulatory clearances.


Kaiga in Uttara Kannada district of Karnataka comprises four indigenously developed Pressurized Heavy Water Reactors of 220 MW (KGS 1 to 4 – 4X220 MW), fuelled by domestic fuel. KGS-2,3& 4 are presently operating, with KGS-2 now operating continuously for 661 days.


Indian nuclear power reactors have achieved continuous operation of over 365 days 28 times till date. Three reactors – KGS-1 (962 days), RAPS-3 (777 days) and RAPS-5 (765 days) – have operated continuously for more than two years.


The record unbroken run of 962 days further demonstrates the pre-eminence of NPCIL in the design, construction and operation of PHWRs with unprecedented levels of efficiency and safety. A synergistic partnership forged between public sector enterprises and the industry partners in the private sector has been instrumental in gaining wide ranging experience and expertise and developing world class technology in this domain, which is now being fruitfully leveraged towards the expansion of the nuclear power programme of the country.


The commendable role played by the Karnataka Power Transmission corporation Limited, Power Grid Corporation of India Limited and Southern Regional Load Despatch Centre by providing stable electrical grid conditions over years of operation thereby preventing tripping of the reactor- has also been a crucial contributor towards achieving this milestone.


With the year 2018 once again drawing world attention to the alarming spectre of global warming, it is recognised that nuclear energy would play an important role in climate change mitigation as a source of clean, green, safe and reliable energy. On the dawn of the year 2019, this significant news reaffirms the commitment of DAE to nuclear power, as being a clean, green, safe and reliable source of energy.
