Expansion Plans: A Path to Energy Security and Sustainability

Introduction

India is at a critical juncture in its energy transition, with growing electricity demands, a push for clean energy, and a need for energy security. To address these challenges, the Indian government has set an ambitious target of expanding its nuclear power capacity to 100 gigawatts (GW) in the coming decades. This expansion aims to reduce the country’s dependence on fossil fuels while meeting its rising energy needs through a reliable and sustainable source.

Nuclear power is seen as a crucial element of India’s “Net Zero by 2070” strategy, complementing renewable energy sources like solar and wind. With advanced reactor technologies, international collaborations, and significant policy reforms, India is poised to become a global leader in nuclear energy.

This article explores India’s nuclear energy landscape, ongoing and upcoming projects, technological advancements, challenges, and the future of nuclear power in the country.

The Current State of Nuclear Power in India

How Much Nuclear Power Does India Generate?

As of 2025, India has:

7.5 GW of nuclear power capacity
22 operational nuclear reactors
10 new reactors under construction (expected to add 7.5 GW more capacity by 2031)

Despite being the third-largest producer of electricity globally, India’s nuclear power contributes only 3% of the total energy mix. The government plans to increase this share to 10% by 2040, making nuclear a significant pillar of India’s clean energy transition.

Major Nuclear Power Plants in India

India’s nuclear power is managed by the Nuclear Power Corporation of India Limited (NPCIL). Some of the key operational nuclear power plants include:

Kudankulam Nuclear Power Plant (Tamil Nadu) – India’s largest nuclear plant, built in collaboration with Russia, with a total capacity of 6,000 MW (when fully completed).
Tarapur Atomic Power Station (Maharashtra) – India’s first nuclear plant, operational since 1969.
Rajasthan Atomic Power Station (Rajasthan) – One of the oldest nuclear power facilities in India.
Kakrapar Atomic Power Station (Gujarat) – Recently upgraded with new reactors.
Kaiga Generating Station (Karnataka) – A key facility for nuclear energy in southern India.

With new projects under development, India aims to add substantial nuclear capacity to meet future energy demands.

India’s 100 GW Nuclear Expansion Plan

The Roadmap to 100 GW

The Indian government has outlined a three-phase nuclear power program to achieve 100 GW capacity:

Phase 1: Pressurized Heavy Water Reactors (PHWRs) – Current Fleet Expansion

India primarily uses PHWRs, which run on natural uranium and heavy water as a moderator.
Plans are underway to construct more 700 MW PHWRs, like the Kakrapar Unit-3 and 4 and the upcoming Gorakhpur Nuclear Plant (Haryana).

Phase 2: Fast Breeder Reactors (FBRs) – Next-Generation Nuclear Power

The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam is expected to begin operation by 2025.
FBRs use plutonium and thorium, making India self-reliant in nuclear fuel.

Phase 3: Thorium-Based Reactors – India’s Long-Term Strategy

India has the world’s largest thorium reserves, estimated at 360,000 tonnes.
The Advanced Heavy Water Reactor (AHWR) is being developed to use thorium efficiently.
Thorium reactors will be the backbone of India’s future nuclear power, making it less dependent on imported uranium.

Upcoming and Under-Construction Nuclear Projects in India

India is aggressively expanding its nuclear infrastructure with several new projects:

1. Kudankulam Nuclear Power Plant Expansion (Tamil Nadu)

Units 3, 4, 5, and 6 are under construction.
Each unit will generate 1,000 MW.
Built in collaboration with Russia’s Rosatom.

2. Gorakhpur Nuclear Power Plant (Haryana)

First large-scale nuclear plant in North India.
Will have two 700 MW PHWRs.

3. Chutka Nuclear Power Plant (Madhya Pradesh)

Expected capacity: 1,400 MW.
Will help power central India.

4. Jaitapur Nuclear Power Plant (Maharashtra)

Will be India’s largest nuclear power plant, with six reactors of 1,650 MW each.
Developed with France’s EDF.
Total capacity: 9,900 MW.

5. Mahi Banswara Nuclear Power Plant (Rajasthan)

Will have four 700 MW PHWRs.
Expected completion by 2030.

India’s focus on domestic reactor production, fast breeder technology, and international collaborations will accelerate its nuclear expansion.

Technological Innovations in India’s Nuclear Energy Program

1. Advanced Heavy Water Reactors (AHWRs)

AHWRs are next-generation reactors designed to run on thorium instead of uranium.
They have passive safety systems, making them safer than traditional reactors.
The first AHWR prototype is under development in BARC (Bhabha Atomic Research Centre).

2. Small Modular Reactors (SMRs)

India is exploring SMRs, which are compact, scalable nuclear reactors.
SMRs can be deployed in remote locations where large nuclear plants are not feasible.
They promise lower costs, faster construction, and increased safety.

3. Fusion Research – Future of Unlimited Energy

India is part of the International Thermonuclear Experimental Reactor (ITER) project in France.
If successful, nuclear fusion could provide limitless clean energy in the future.

Challenges in Expanding Nuclear Power in India

Despite the ambitious plans, India faces several challenges in achieving 100 GW nuclear power capacity:

1. Public Opposition and Land Acquisition

Local protests have delayed projects like Jaitapur and Kudankulam.
The government needs better public awareness programs to address safety concerns.

2. Uranium Supply Limitations

India depends on imports for uranium, mainly from Russia, Canada, and Kazakhstan.
The development of thorium reactors will reduce this dependency.

3. High Initial Costs and Financing Issues

Nuclear plants require billions of dollars in investment.
India is seeking foreign investments and collaborations to fund new projects.

4. Nuclear Waste Management

Safe disposal and recycling of nuclear waste remain a critical challenge.
India is working on reprocessing technologies to reduce waste and reuse materials.

The Future of Nuclear Energy in India

With strong government policies, international collaborations, and advanced reactor technologies, India’s nuclear power sector is set for exponential growth.

1. Contribution to India’s Net-Zero Goals

Nuclear energy will play a crucial role in India’s carbon-neutral strategy.
It provides a stable, clean energy source compared to coal-based power.

2. Global Leadership in Nuclear Technology

India is emerging as a leader in thorium reactor development.
The export of nuclear technology to other countries could become a future revenue source.

3. Increasing Private Sector Involvement

The Indian government is opening nuclear power projects to private investment.
Companies like L&T and Reliance are exploring partnerships in the nuclear sector.

Conclusion

India’s nuclear power expansion plan is a bold step towards energy security, sustainability, and global leadership in advanced nuclear technologies. With an ambitious goal of 100 GW capacity, the country is set to revolutionize its energy mix and reduce reliance on fossil fuels.

While challenges remain, technological advancements, international collaborations, and strong policy support will ensure that India becomes a nuclear powerhouse in the 21st century.

The future of energy is nuclear, and India is leading the way! 🚀
