'''Kakrapar Atomic Power Station''' is a [[nuclear power]] station in [[India]], which lies in the proximity of Mandvi, [[Surat]] and [[Tapti River|Tapi river]] in the state of [[Gujarat]]. After commissioning units 3 and 4, the power plant has become the second largest nuclear power plant in the country after the [[Kudankulam Nuclear Power Plant]] in terms of installed capacity.

==Phase I==
Phase I consist two 220 MW [[pressurised water reactor]] with [[heavy water]] as moderator (PHWR). KAPS-1 went critical on 3 September 1992 and began commercial electricity production a few months later on 6 May 1993. KAPS-2 went critical on 8 January 1995 and began commercial production on 1 September 1995. In January 2003, [[CANDU Owners Group]] (COG) declared KAPS as the best performing pressurised heavy water reactor.<ref>{{cite news|last=Kurian|first=Vinson|title=Indian N-reactors set new global benchmark|url=http://www.thehindubusinessline.in/2003/03/27/stories/2003032702500400.htm|newspaper= [[The Hindu Business Line]]|date=26 March 2003|access-date=16 February 2017}}</ref>

KAPS-2 was shut down after a coolant channel leak in July 2015 and a similar issue forced the shutdown of KAPS-1 in March 2016. After a replacement of coolant channels and feeder tubes, KAPS-2 attained criticality in September 2018. Maintenance on KAPS-1 was completed ahead of schedule and was brought to operation on 19 May 2019.<ref name="kaps1"/>

The construction costs were originally estimated to be ₹382.52[[Crore| crore]]; the plant was finally finished at a price of ₹1,335 crore.

==Phase II==
In 2007 the [[First Manmohan Singh ministry]] approved outline plans to build two Indian-designed [[IPHWR-700]] reactors, with two sister reactors a little later at [[Rajasthan Atomic Power Station]]. In 2009 approval was confirmed, and site preparation was completed by August 2010. The first concrete for Kakrapar 3 and 4 was in November 2010 and March 2011 respectively with operation originally expected by early and late 2018 respectively.<ref name=nei-20170816>{{cite news |url=https://www.neimagazine.com/features/featurebright-prospects-for-indias-future-fleet-5901895/ |title=Bright prospects for India's future fleet |publisher=Nuclear Engineering International |date=16 August 2017 |access-date=23 July 2020 |archive-date=20 July 2020 |archive-url=https://web.archive.org/web/20200720044815/https://www.neimagazine.com/features/featurebright-prospects-for-indias-future-fleet-5901895/ |url-status=dead }}</ref><ref name=wnn-20200722>{{cite news |url=https://www.world-nuclear-news.org/Articles/Kakrapar-3-achieves-first-criticality |title=Kakrapar 3 achieves first criticality |publisher=World Nuclear News |date=22 July 2020 |access-date=23 July 2020}}</ref>

The project over-ran largely due to tuning of the IPHWR-700 design and slow delivery of supplies.<ref name=nei-20170816/>

Unit 3 achieved the first criticality on 22 July 2020. It was connected to the grid on 10 January 2021.<ref name="lm-102021">{{cite web|url=https://www.livemint.com/industry/energy/unit-3-of-kakrapar-nuclear-plant-synchronised-to-grid-11610365657066.html|title=Unit 3 of Kakrapar nuclear plant synchronised to grid|publisher=Live Mint|date=10 January 2021|access-date=18 January 2021}}</ref> This unit began commercial operation on 30 June 2023.<ref>{{Cite news |date=2023-07-04 |title=India's Kakrapar 3 begins commercial operation |work=World Nuclear News |url=https://www.world-nuclear-news.org/Articles/India-s-Kakrapar-3-begins-commercial-operation |access-date=2023-07-25}}</ref> Unit 3 achieved operations at full load on 31 August 2023.<ref>{{cite news|url=https://www.freepressjournal.in/india/gujarat-india-achieves-another-milestone-as-first-indigenous-700-mw-nuclear-plant-starts-operations-at-100|title=Gujarat: 'India Achieves Another Milestone' As First Indigenous 700 MW Nuclear Plant Starts Operations At 100%|work=Free Press Journal|date=2023-08-31}}</ref>

Unit 4 was commissioned after many tests. Hot functional testing was scheduled around June 2023 and criticality was initially planned around September 2023. The Initial Fuel Loading (IFL) commenced on 20 October 2023 after permission was granted by the [[Atomic Energy Regulatory Board]].<ref>{{Cite news |date=2023-10-21 |title=NPCIL starts loading fuel in home-built 700 MW n-power plant at Kakrapar|work=ET EnergyWorld |url=https://energy.economictimes.indiatimes.com/news/power/npcil-starts-loading-fuel-in-home-built-700-mw-n-power-plant-at-kakrapar/104598320 |access-date=2023-10-21}}</ref> Unit 4 achieved first criticality on 17 December 2023.<ref>{{Cite news |date=2023-12-17|title=Kakrapar-4 nuclear reactor attains criticality|work=The Hindu|url=https://www.thehindu.com/news/national/second-home-built-700-mw-nuclear-plant-at-kakrapar-achieves-first-criticality/article67647599.ece/amp/|access-date=2023-12-17}}</ref> The reactor was connected to the grid on 20 February 2024.<ref>{{cite web|url=https://www.nucnet.org/news/kakrapar-4-reactor-connected-to-the-grid-as-nation-pushes-for-major-expansion-of-nuclear-power-2-1-2024|title=Kakrapar-4 Reactor Connected To Grid As Nation Pushes For Major Expansion Of Nuclear Power|first=Kamen|last=Kraev|work=NucNews|date=2024-02-24}}</ref> Unit 4 started commercial operation from 31 March, 2024.<ref>{{cite web|url=https://www.npcil.nic.in/WriteReadData/userfiles/file/MA_News_16042024_01.pdf|title=MAJOR ACHIEVEMENTS OF NPCIL IN MARCH 2024|work=NPCIL|date=2024-04-16}}</ref>

== Incidents ==
* 1998 KAPS-1 was switched off because of a leakage in the cooling loop for 66 days.
* 10 March 2004 the (at the time of) supply for the control rods were irreparably damaged during maintenance work. In response, poisons were added to the system and the reactor was shut off.
* On 22 August 2006 it was reported by village inhabitants the area around the power station had been penetrated. A search by the police did not result in any findings.
