Nuclear Energy in India | UPSC Concept

What is Nuclear Energy in India?

Nuclear energy is the energy released from the nucleus of an atom, typically through nuclear fission the splitting of heavy atomic nuclei, to generate electricity. It is a non-renewable but low-carbon source of power.

Historical Background

India's nuclear program was initiated by Dr. Homi J. Bhabha in the 1940s, focusing on self-reliance. The Atomic Energy Act 1962 provided the legal framework. India developed a unique three-stage nuclear power program to utilize its vast thorium reserves.

Key Points

8 points

1.
First Stage: Pressurized Heavy Water Reactors (PHWRs) using natural uranium and producing plutonium as a byproduct.
2.
Second Stage: Fast Breeder Reactors (FBRs) using plutonium from the first stage and natural uranium to produce more plutonium and U-233 from thorium.
3.
Third Stage: Advanced Heavy Water Reactors (AHWRs) using thorium-U233 fuel cycle, aiming for long-term energy security.
4.
India is not a signatory to the Nuclear Non-Proliferation Treaty (NPT) but adheres to IAEA safeguards for civilian nuclear facilities.
5.
Current installed nuclear power capacity is approximately 7.48 GW from 22 reactors, contributing about 3% of India's electricity.
6.
Advantages include low carbon emissions, high power output, and energy security.
7.
Disadvantages involve high capital costs, nuclear waste management, safety concerns, and proliferation risks.
8.
Key institutions: Department of Atomic Energy (DAE), Nuclear Power Corporation of India Limited (NPCIL), Atomic Energy Regulatory Board (AERB).
