Nuclear energy is an important part of India’s energy system. As the country works to meet its increasing energy needs and reduce reliance on fossil fuels, nuclear power offers a reliable and eco-friendly solution. Over the years, India has made great progress in expanding its nuclear energy sector, with several nuclear power plants already in operation, some under construction, and more planned for the future.

Here we will look at the current state of nuclear power plants in India, how they contribute to the energy supply, the challenges they face, and future plans, including the move towards Small Modular Reactors (SMRs).

Nuclear Power Plants in India

Nuclear power is expected to play an increasingly significant role in India’s future energy strategy. As the world shifts toward clean energy sources to combat climate change, nuclear energy offers a low-carbon, reliable option. India’s growing demand for electricity, coupled with its commitment to reducing carbon emissions, makes nuclear energy an essential part of the country’s energy mix.

In addition to large-scale reactors, the development of Small Modular Reactors (SMRs) promises to revolutionize India’s nuclear power generation. SMRs can offer solutions to some of the challenges faced by traditional nuclear plants, such as safety concerns and high construction costs.

Moreover, India’s ongoing research in thorium-based reactors and its partnership with Russia for the Kudankulam plant exemplifies the country’s commitment to expanding its nuclear energy capabilities. As more reactors are commissioned, India’s nuclear power capacity is poised to rise significantly in the coming decades, contributing to the nation’s energy security.

How Many Nuclear Power Plants Are in India?

India has 22 operational nuclear power reactors, with a total installed capacity of 6,780 MW. Additionally, there are 8 reactors under construction at various stages, including the 500 MW Prototype Fast Breeder Reactor (PFBR) being implemented by BHAVINI, which will add a total of 6,000 MW to the country’s nuclear capacity. These reactors are spread across several plants like Tarapur, Kudankulam, and Rawatbhata, contributing significantly to the country’s energy needs. As India continues to expand its nuclear energy sector, it aims to meet growing energy demands and reduce reliance on fossil fuels.

List of Nuclear Power Plants in India

India has a number of nuclear power plants spread across various states, primarily operated by the Nuclear Power Corporation of India Limited (NPCIL). These plants utilize different reactor technologies, such as Pressurized Heavy Water Reactors (PHWR), Light Water Reactors (LWR), and Fast Breeder Reactors (FBR). Here is a list of all the nuclear power plants in India:

India’s First Nuclear Power Plant

India’s first nuclear power plant was the Tarapur Atomic Power Station, commissioned in 1969. Located in Maharashtra, it initially used American-supplied BWR technology. Over the years, Tarapur has undergone upgrades, and Units 3 and 4 now operate with PHWR technology, providing a combined capacity of 980 MW.

Largest Nuclear Power Plant in India

As of 2024, the Kudankulam Nuclear Power Plant in Tamil Nadu is the largest nuclear power plant in India. With a total planned capacity of 6,000 MW (from six reactors), it is a major player in the country’s nuclear energy landscape. This plant uses Russian-designed VVER-1000 reactors, which are some of the most advanced pressurized water reactors globally.

Recent Developments in Nuclear Power Plants in India

India’s nuclear power sector is evolving with a focus on technological advancements, increasing capacity, and ensuring sustainability:

• Bharat Small Reactors (BSR): India is working on the development of compact, modular reactors that allow for flexible and cost-efficient nuclear power generation. This represents a move away from traditional large-scale reactors, with innovation being driven by partnerships in the private sector.

• Capacity Expansion: The Indian government aims to significantly boost nuclear energy capacity, with plans to triple it by 2032. Currently, six reactors are under construction, and proposals for larger reactors are in the pipeline.

• International Collaboration: India is strengthening its uranium imports and forming agreements with countries like France and Russia to access advanced reactor technology.

• Sustainability Goals: The 2024 Budget focuses on funding research into low-emission energy technologies, such as ultra-supercritical thermal plants, in line with India’s commitment to reducing greenhouse gas emissions.

These efforts are set to help India meet its growing energy needs while adhering to environmental goals.

Advantages of Nuclear Power Plants in India

Advantages of nuclear power plants in India are:

• Low Carbon Emissions: Nuclear energy generates minimal greenhouse gas emissions, helping to promote cleaner energy and address climate change.

• Energy Efficiency: Nuclear reactors produce large quantities of energy from small amounts of fuel, ensuring high energy efficiency.

• Energy Security: By reducing reliance on imported fossil fuels, nuclear power strengthens India’s energy independence.

• Base Load Power: Nuclear power provides a consistent and reliable energy supply, unlike renewable sources such as solar or wind that are intermittent.

• Long-Term Cost Effectiveness: Despite high initial investment, nuclear plants have low operating and fuel costs over time, making them cost-effective in the long run.

• Supports Technological Advancement: Nuclear energy drives research, fosters innovation, and enables the development of advanced reactors, including thorium-based systems.

• Employment Opportunities: Nuclear plants create jobs in construction, operation, and maintenance, boosting employment opportunities.

• Utilization of Indigenous Resources: India makes use of its thorium reserves as part of its three-stage nuclear program, promoting the use of domestic resources.

Who Regulates Nuclear Power Plants in India?

In India, nuclear power plants are regulated by the Atomic Energy Regulatory Board (AERB), which works under the Department of Atomic Energy (DAE). The AERB makes sure that nuclear plants follow safety rules to protect people and the environment. It creates and enforces rules for designing, running, and closing down nuclear plants. Nuclear Power Corporation of India Limited (NPCIL) is in charge of running the nuclear plants and works with AERB to make sure they meet safety standards.
