उत्तर
- Nuclear power is generated using radioactive minerals like uranium and thorium.
- It is a powerful source of energy and can generate electricity on a large scale.
- India has large deposits of thorium (Kerala monazite sands) and smaller reserves of uranium (Jharkhand, Rajasthan, Andhra Pradesh).
- Major nuclear power stations in India are located at Tarapur (Maharashtra), Rawatbhata (Rajasthan), Kalpakkam (Tamil Nadu), Narora (U.P.), Kakrapar (Gujarat), Kaiga (Karnataka), Kudankulam (Tamil Nadu).
- Nuclear energy is important for meeting India’s growing electricity needs and reducing dependence on coal and petroleum.
