Three Stage Nuclear Power Programme

Globally Advanced Technology

Globally Unique

World class performance

  • Stage – I PHWRs
  • 14 - Operating
  • 4 - Under construction
  • Several others planned
  • Scaling to 700 MWe
  • Gestation period has been reduced
  • POWER POTENTIAL  10,000 MWe
  • LWRs
  • 2 BWRs Operating
  • 2 VVERs under
  • construction
  • Stage - III
  • Thorium Based Reactors
  • 30 kWth KAMINI- Operating
  • 300 MWe AHWR- Under Development
  • POWER POTENTIAL IS VERY LARGE
  • Availability of ADS can enable early introduction of Thorium on a large scale
  • Stage - II
  • Fast Breeder Reactors
  • 40 MWth FBTR - Operating since 1985
  • Technology Objectives realised
  • 500 MWe PFBR-
  • Under Construction
  • POWER POTENTIAL  530,000 MWe

  • Calorific valueof fossil fuels (kcal/kg)

Domestic Coal: 4000, Imported Coal: 5400, Naphtha: 10500, LNG: 9500

  • Indian uranium-ore contains only 0.06% of uranium (Canada’s 18%), but this provides
    • 20times more energy per tonne of mined material than coal when uranium is used in once through open cycle inPHWRs
    • 1200 to 1400times more energy per tonne of mined material than coal when used in closed cycle based onFBRs
  • 1000 MWe Nuclear Power Plant needs movement of 12 trucks (10 Te/truck) of uranium fuel per year
  • 1000 MWe Coal Power Plant needs movement of 3,80,000 trucks (10 Te/truck) of coal per year

challenges and strategies
Challenges and strategies
  • A country of the size of India cannot afford to plan its economy on the basis of large scale import of energy resources or energy technology
  • Indigenous development of energy technologies based

on domestic fuel resources should be a priority for us.

  • Nuclear power must contribute about a quarter of the total electric power required 50 years from now, in order to limit energy import dependence in percentage terms at about the current level.
