Rajastan Atomic Power Project
The Rajasthan Atomic Power Station (RAPS; also ''Rajasthan Atomic Power Project'' - RAPP) is located at Rawatbhata in the state of Rajasthan, India. History The construction of the Douglas Point Nuclear Generating Station Canada began in 1961 with a CANDU (Canada Deuterium Uranium) pressurised heavy water reactor (PHWR) capable of producing 220 MW of electricity. Two years after the construction of the Rajasthan Power Project (RAPP) commenced, two similar reactors were built in the state of Rajasthan. Ten years later, in 1973 RAPS-1 was put into service. In 1974 after India conducted Smiling Buddha, its first nuclear weapons test Canada stopped its support of the project, delaying the commissioning of RAPS-2 until 1981. 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 ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India's Three-stage Nuclear Power Programme
India's three-stage nuclear power programme was formulated by Homi Bhabha, the well-known physicist, in the 1950s to secure the country's long term energy independence, through the use of uranium and thorium reserves found in the monazite sands of coastal regions of South India. The ultimate focus of the programme is on enabling the thorium reserves of India to be utilised in meeting the country's energy requirements. Thorium is particularly attractive for India, as India has only around 1–2% of the global uranium reserves, but one of the largest shares of global thorium reserves at about 25% of the world's known thorium reserves. However, thorium is more difficult to use than uranium as a fuel because it requires breeding, and global uranium prices remain low enough that breeding is not cost effective. India published about twice the number of papers on thorium as its nearest competitors, during each of the years from 2002 to 2006. The Indian nuclear establishment estimates ...

Pressurized Heavy-water Reactor
A pressurized heavy-water reactor (PHWR) is a nuclear reactor that uses heavy water ( deuterium oxide D2O) as its coolant and neutron moderator. PHWRs frequently use natural uranium as fuel, but sometimes also use very low enriched uranium. The heavy water coolant is kept under pressure to avoid boiling, allowing it to reach higher temperature (mostly) without forming steam bubbles, exactly as for pressurized water reactor. While heavy water is very expensive to isolate from ordinary water (often referred to as ''light water'' in contrast to ''heavy water''), its low absorption of neutrons greatly increases the neutron economy of the reactor, avoiding the need for enriched fuel. The high cost of the heavy water is offset by the lowered cost of using natural uranium and/or alternative fuel cycles. As of the beginning of 2001, 31 PHWRs were in operation, having a total capacity of 16.5 GW(e), representing roughly 7.76% by number and 4.7% by generating capacity of all current o ...
