Scenarios for Total Installed Power Capacity in India(DAE-2004 and Planning Commission-2006 studies)
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
Comparison of Fuel Characteristics • 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 • 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.
