The Rajasthan Atomic Power Station (RAPS; also Rajasthan Atomic Power Project - RAPP) in India is located about 65 kilometres (40 mi) from Kota by way of the Chambal River, approximately 3 kilometres (1.9 mi) above the dam that holds the Rana Pratap Sagar lake. The plant lies in the Federal State Rajasthan, district Chittorgarh. The next locale is Tamlao, Rawatbhata is approx. 11 kilometers far away, which is where the plant is located. In Kota a factory for heavy water operated in the 1980s.

The Douglas Point reactor in Canada was begun in 1961, a duplicate station at Rajasthan, was committed in 1963. The Rajasthan Power Project (RAPP) included two 220 MWe CANDU reactors built in the state of Rajasthan and put into service, respectively, in 1973 and 1981. Indian tradesmen and professional engineers came to be trained at Douglas Point. After the nuclear bomb test explosion in 1973 the nuclear trade links between Canada and India were curtailed and the second RAPP reactor was completed by the Indians with no Canadian assistance.

After many incidents and repairs[citation needed] RAPS-1 has now a 100 MW capacity, RAPS-2 at 200 MW.

In the context of the Indian atomic program, two more PHWR with an output of 220 MW each were built. They cost around 570 million dollars. RAPS-3 became critical on 24 December 1999, RAPS-4 became critical on 3 November 2000. Commercial operations began on 1 June 2000 for unit 3, and on 23 December 2000 for unit 4.

Two more reactors (RAPS-5 and RAPS-6) with 220 MWe have also been built, with unit 5 beginning commercial operation on 4 February 2010, and unit 6 on 31 March 2010.[1]

Two of the new Indian-designed 700 MWe series of reactor (RAPP-7 and RAPP-8) are under construction at Rajasthan.

In November 2012, International Atomic Energy Agency(IAEA) intensively audited over several weeks two reactors at the Rajasthan Atomic Power Station for safety. It has concluded that the reactors are among the best in the world, the indigenously made 220 MW atomic plants can withstand a Fukushima type of accident, even suggesting that the "safety culture is strong in India" and that India emerged a winner with a high global safety rank.[2]

First concrete for unit 7 was poured on 18 July 2011,[3] with commercial operation expected by 2016. The two reactors will cost an estimated Rs 123.2 billion (US$2.6 billion).[4]

2006 meteorite[edit]

On 29 August 2006, a 90% iron meteorite weighing 6.8 kilograms fell in Kanvarpura village, near the power station. The Deputy Director-General (western region) of the Geological Survey of India, R.S. Goyal, said that devastation on an "unimaginable scale" would have ensued had the object struck the station.[5]

2012 nuclear leak[edit]

In June 2012, 38 workers were exposed to tritium when a welding operation went wrong inside the protected environment of the reactor.[6]
