THE MINISTER OF STATE FOR SCIENCE & TECHNOLOGY AND EARTH SCIENCES
(INDEPENDENT CHARGE), PMO, PERSONNEL, PUBLIC GRIEVANCES AND PENSIONS
AND PARLIAMENTARY AFFAIRS(SHRI PRITHVIRAJ CHAVAN)
(a) Out of seventeen (17) nuclear power reactors in the country, eleven (11)
reactors are not operating at optimum capacity.These reactors use indigenous
Uranium, which is not available in the required quantity.Three reactors use
imported uranium and operate at maximum capacity.Three reactors are currently
under long term maintenance and are shut down.
(b) The capacity utilization factor of these plants and the total loss of
generation of power from such plants in million units during the last three years
and the current year are given below:-

Notes
The normative capacity factor for nuclear power reactors is 68.5%.The loss of
generation is thus based on normative CF.
1. TAPS-3 commenced commercial operation on 18.08.2006
2. KGS-3 commenced commercial operation on 06.05.2007
3. RAPS-1 shutdown from 09.10.2004 for review of continuation of operation.
4. NAPS-1 shutdown for EMCCR from 01.11.05 to 24.02.2008
5. RAPS-2 shut down for EMFR from 02.07.2007 to 31.08.2009
6. NAPS-2 is shutdown for EMCCR since 18.12.2007
7. KAPS-1 is shut down for EMCCR since 01.07.2008
(c) The Government has taken steps to augment supply of indigenous uranium and
use of imported uranium for reactors under the International Atomic Energy Agency
(IAEA) safeguards.Resulting of these measures, overall capacity utilization of the
nuclear plants are progressively improving. The capacity utilization which was
about 50% in the year 2008-09 is higher at about 60% for the period April-November,
2009.
