Nuclear Power Plants in India
There are 22 nuclear power reactors which are operational in the country with a total installed capacity of 6780 MW. In addition, there are 8 reactors (including 500 MW PFBR being implemented by BHAVINI) totaling to 6000 MW under construction at various stages.
There are presently four reactors with a capacity of 2800 MW under construction and the construction of five more reactors capacity of 3900 MW has also commenced. On their progressive completion, the capacity will reach 13480 MW.
| # | Location | State | Capacity (MW) |

| 3 | Narora | Uttar Pradesh | 440 |
| 4 | Kakrapar | Gujarat | 440 |
| 5 | Kaiga | Karnataka | 880 |
| 6 | Kalpakkam | Tamil Nadu | 440 |
| 7 | Kudankulam | Tamil Nadu | 2000 |
| Total | 6780 |
KAPP-3 (700 MW) has been connected to the grid on January 10, 2021.
Under Construction Nuclear Power Plants
| # | Location | State | Project | Capacity (MW) |
| 1 | Kakrapar | Gujarat | KAPP 4 | 1 x 700 |
| 2 | Rawatbhata | Rajasthan | RAPP 7 & 8 | 2 x 700 |
| 3 | Gorakhpur | Haryana | GHAVP 1 & 2 | 2 x 700 |
| 4 | Kudankulam | Tamil Nadu | KKNPP 3 & 4 | 1 x 1000 |
| 5 | Kalpakkam | Tamil Nadu | PFBR | 1 x 500 |
In addition, there are 8 reactors (including 500 MW PFBR being implemented by BHAVINI) totaling to 6000 MW under construction at various stages.
The Pressurised Heavy Water Reactors (PHWRs) are fueled by Natural Uranium while Light Water Reactors (LWRs) are fueled by Low Enriched Uranium.
The annual requirement of fuel (UO2) of a 700 MW PHWR (at 85% Capacity Factor) is about 125 tons and that of a 1000 MW LWR (at a capacity factor of 90%), about 25 tons.
Prototype Fast Breeder Reactor (PFBR) being implemented by Bharatiya Nabhikiya Vidyut Nigam Limited (BHAVINI) is fuelled by Mixed Oxide (MoX) Fuel.
Upcoming Nuclear Power Plants
The Government has accorded administrative approval and financial sanction for construction of 12 nuclear power reactors - 10 indigenous 700 MW Pressurized Heavy Water Reactors (PHWRs) to be set up in fleet mode and 2 units of Light Water Reactors (LWRs) to be set up in cooperation with Russian Federation. On progressive completion of the projects under construction and accorded sanction, the nuclear capacity is expected to reach 22,480 MW by 2031.
The Government has also accorded ‘In-Principle’ approval for five new sites for locating nuclear power plants in future.
