Nuclear Power Resources in India

To use uranium and vast thorium resources of the country, a three-stage atomic power programme was envisaged in 1940s. The ongoing first stage of the programme uses natural uranium fuelled pressurized heavy water reactors (PHWRs) for producing electricity. The spent fuel, when reprocessed, yields plutonium which will be used as fuel along with depleted uranium in the second stage fast breeder reactors (FBRs). Reprocessing of the second stage spent fuel will result in production of more plutonium and uranium-233 when thorium is used as a blanket. The third stage reactors will be using uranium-233.

A Power Project Engineering Division was established in 1967 to assume responsibility for building nuclear power stations. In August 1984 this Division was re-constituted as the Nuclear Power Board to implement the nuclear power program in the country. For greater operational flexibility, the Nuclear Power Board was converted into the Nuclear Power Corporation which started functioning from 17 September 1987. Generation of electricity from nuclear energy commenced in 1969 with the commissioning of Tarapur Atomic Power Station (TAPS) consisting of two enriched uranium fuelled boiling water reactors of 210 MW capacities each. Two prototype PHWR units of the Rajasthan Atomic Power Station (RAPS), using natural uranium as fuel and 220 MW capacities each, attained criticality in December 1972 and April 1981 at Rawatbhatta (Rajasthan). On 27 January 1984, the Madras Atomic Power Station (MAPS) at Kalpakkam, near Chennai started commercial operation, and the second reactor followed suit on 21 March 1986, these were the first reactors which went critical on 12 March 1989 and 24 October 1991. The Narora reactors are standardised versions of 220 MW reactors and all the future 220 MW PHWRs will be of this design. A 220 MW reactor of Kakrapar Atomic Power Station (KAPS) has synchronised with the grid on. With this, the installed nuclear power generation capacity in the country is 1,720 MW. Four more reactors of 220 MW series are under construction two each at Rawatbhatta (Rajasthan) and Kaiga (Karnataka) and four are at planning stage at Kaiga. The design of the 200 MWs has also been upgraded to 500 MW. Six reactors of this capacity will be set up at Tarapur (two units) and Rawatbhatta (500 units). Two pressurised water reactor units (VVER type) of 1000 MW capacity each will be set up at Kudankulam (Tamil Nadu) in collaboration with Russia. On 18 October 1985 the 40 MW sodium cooled fast breeder test reactor (FBTR) using indigenously developed plutonium carbide fuel, attained criticality at Kalpakkam (Tamil Nadu) With this a beginning was made in the second stage of the nuclear power program.

Heavy Water Production: Heavy water is used as moderator and coolant in PHWRs. The country’s first heavy water plant set up at Nangal (Punjab), has been in operation since 1962. The heavy water plants using ammonia-hydrogen exchange process were subsequently set up at Baroda (Gujarat), Talcher (Orissa), Tuticorin (Tamil Nadu), Thal (Maharashtra) and Hazira (Gujarat). Heavy water production technology using hydrogen sulphide water exchange process was developed indigenously. Based on this process, the first commercial plant was set up at Rawatbhatta (Rajasthan), followed by second plant commissioned at Manuguru (Andhra Pradesh) in 1992.

Nuclear Fuel Production: Exploration, mining and fuel fabrication, the front-end activities of the nuclear power program have been established in the country through totally indigenous technology. Significant quantities of uranium thorium and other nuclear minerals have been added to the mineral inventories. The uranium reserves are sufficient to support the first stage 10.000 MWe (PHWR) of nuclear power generation over the design life. Exploitation of thorium reserves would lead to supporting about 2,50,000 MWe. The natural uranium oxide ore is processed and converted to yellow cake at the Uranium Corporation of India Limited, Jaduguda (Jharkhand) wihich is an input for fuel fabrication activities at the Nuclear Fuel Complex established in 1971 at Hyderabad. India has also developed technologies for the reprocessing of spent fuel and waste management. Since the sixties, spent fuel has been reprocessed indigenously and the waste management program is also well established. India is now amongst a few countries in the world that has developed the technology which converts high level radioactive waste into glass.

Research Development: Research is carried on in fast breeder technology and frontline areas such as lasers accelerators and superconductivity. Research and Development (R&D) activities of DAE (Department of Atomic Energy) are concentrated at four research centres, namely the Bhabha Atomic Research Centre, Trombay; Indira Gandhi Centre for Atomic Research, Kalpakkam; Centre for Advanced Technology, Indore and Variable Energy Cyclotron Centre, Kolkata. Bhabha Atomic Reasearch Centre: Set up in 1957, the Bhabha Atomic Research Centre (BARC) is a premier research institution of the country working in nuclear sciences and related fields. The country’s first 1 MW research reactor “APSARA” was built indigenously in 1956. In 1960, a 40 MW research reactor “CIRUS” was commissioned at Trombay for developmental work including production of isotopes, experimentation, and training. “CIRUS” is still in operation. A new high flux indigenous 100 MW reactor “DHRUVA” was commissioned in August 1985 for research in advanced nuclear physics and production of isotopes. Other facilities of BARC Include a research reactor “PURNIMA” 111 using uranium-233 as fuel, a neutron source reactor “KAMINI” (at Kalpakkam), a 5.5 MeV Van-de-Graff accelerator at Colaba, Mumbai set up in collaboration with TIFR, a Beryllium Plant at Vashi (New Mumbai). Power Reactor Fuel Reprocessing Plant (PREFRE), Waste Immobilisation Plant at Tarapur, and a seismic station at Gauribidanur (Karanataka). The Radiation Medicine Centre of BARC at Mumbai uses radioisotopes for diagnostic and therapeutic applications.

BARC provides the much needed R&D back-up for the nuclear power programme, and other units of the industry and mineral sector. This Centre has also developed technologies in peaceful uses of atomic energy such as applications of radioisotopes in industry, medicine and agriculture. The outcome of the research work done has resulted in production of radio pharmaceuticals, and labeled compounds. high yielding crop varieties. preservation of spices and sea foods by irradiation. A number of technologies developed at BARC have been transferred to industries for commercial use. The Centre has a Health Physic Division which provides countrywide health monitoring services for radiation workers.

Indira Gandhi Centre for Atomic Research: Set up in 1971 at Kalpakkam, near Chennai, the Centre carries out R&D activities relating to fast breeder development. This Centre has set up a fast breeder test reactor (FBTR) presently operating at a power level of 1 MW. Based on the experience gained from (FBIR) this centre has evolved a design for the prototype 500 MW reactor (PFBR) and is equipped with modern laboratories for carrying out work in metallurgy, radio chemistry and fuel reprocessing related to fast reactors.
