The Kakrapar Atomic Power Station (KAPS) is a nuclear power station in India, which lies in the proximity of the city of Surat in the state of Gujarat. It consists of two 220 MW pressurized water reactors 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 in September 1, 1995. In January 2003 the CANDU Owners Group (COG) distinguished KAPS-1 as the worldwide best PHWR of its class.[1]

The construction costs originally were estimated to be 3.8252 billion Rupees, the plant was finally finished at a price of 13.35 billion Rupees. Construction of units 3 and 4 started in November 2010.[2]


  • 1998 KAPS-1 was switched off because of a leakage in the cooling loop for 66 days.
  • 10 March 2004 the (at the time) 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.


  • Kaps has a glamorous township known as Anumala Township, located in a rural setting some odd 80 kilometres (50 mi) away from the city of Surat.
  • It is some less than 20 kilometres (12 mi) away from Vyara, which is the headquarters of Tapi district formed in Oct 2007.
