View All India Facilities

Last Updated: September 1, 2003
Other Name: N/A
Location: Kota, Rajasthan, India
Subordinate To: Department of Atomic Energy (DAE)
Size: Four pressurized heavy water reactors (PHWRs), one 100MWe, one 200MWe, and two 220MWe
Facility Status: Operational

Located at Rawatbhata in Rajasthan, the Rajasthan Atomic Power Station (RAPS) was the first facility in India to operate pressurized heavy water reactors (PHWRs). RAPS' Unit-1 was built as a 220MWe CANDU PHWR and constructed with Canadian assistance. Although Unit-1 began commercial operations on 16 December 1973, the construction of Unit-2 was delayed when the Canadians withdrew their assistance after the nuclear test at Pokharan in 1974. However, Unit-2 eventually commenced operations in April 1981 as a 220MWe capable PHWR. In 2000, two additional PHWRs began commercial operations at RAPS. The new facilities, Unit-3 and Unit-4, were developed indigenously and generated energy at a 220MWe capacity. Although Unit-1 has experienced numerous problems over the years due to leaks, cracks in the end-shield, and turbine blade failures, the 29-year-old reactor appears to be running at a 100MWe capacity after recent repairs. Unit-2 just underwent a seven-month all inclusive coolant channel replacement and is reportedly operating at 200MWe. The Unit-1 and Unit-2 PHWRs at RAPS fall under International Atomic Energy Agency (IAEA) safeguards.

As of February 28, 2003, RAPS' accumulative generation since it began commercial operations was 41,159 million units (MUs). Unit-1 accounted for 11,445 MUs, Unit-2 for 21,940 MUs, Unit-3 for 4,224 MUs, and Unit-4 for 3,550 MUs. Four additional PHWRs are currently in the pipeline at RAPS. According the Department of Atomic Energy of India, Unit-5 and Unit-6 will have a 220MWe capacity and be ready for operations in 2007. Unit-7 and Unit-8 are reported to be 500MWe PHWRs and may be ready by 2011-2012.
