India's Nuclear Ambition: Charting a Course for a 100GW Clean Energy Future

India's nuclear energy programme is a testament to the country's commitment to innovation, sustainability, and self-reliance. The government's vision of Aatmanirbhar Bharat, or self-reliant India, has guided the development of robust indigenous capabilities across the entire nuclear fuel cycle. This includes reactor design, fuel fabrication, waste management, and advanced technologies.

With 24 operational reactors and 9 under construction, India is rapidly expanding its nuclear energy footprint. The Nuclear Energy Mission (2025-26) and the SHANTI Act, 2025, are accelerating capacity expansion, strengthening domestic manufacturing, and promoting innovation. By harnessing the power of nuclear energy, India is reducing dependence on imported fossil fuels and supporting its climate commitments.

Nuclear power provides round-the-clock, low-carbon electricity, complementing renewable energy while ensuring grid stability. It is an essential component of India's long-term energy strategy, which aims to achieve 100GW of nuclear power capacity by 2047. This ambitious goal is driven by the need for clean, reliable, and stable baseload electricity.

India's nuclear energy programme reflects the country's commitment to innovation, sustainability, and self-reliance. By combining advanced technologies with rigorous safety standards and indigenous capabilities, nuclear energy is helping build a secure and resilient energy future. As the nation progresses towards Viksit Bharat, nuclear energy will continue to complement other clean energy sources, supporting economic growth, environmental sustainability, and long-term energy security.

The country's nuclear energy programme is also focused on utilising its abundant thorium reserves. India has abundant reserves of thorium, a fertile rather than fissile radioactive material, found mainly in the coastal sands of Kerala, Tamil Nadu, Andhra Pradesh, Odisha, West Bengal, and Jharkhand. Inside a reactor, thorium absorbs a neutron and transforms into Uranium-233, which is fissile. This is a key component of India's three-stage nuclear power programme, which aims to utilise thorium as a primary fuel source.

India's nuclear reactors are designed to operate on natural uranium, which does not require enrichment. The country also operates Boiling Water Reactors (BWRs) and Pressurised Water Reactors (PWRs). India is advancing Fast Breeder Reactors (FBRs) to utilise plutonium and support the transition to thorium-based reactors. Small Modular Reactors (SMRs) are also being developed as the next generation of nuclear technology.

Nuclear waste is managed under strict safety standards to ensure the protection of people and the environment. India follows a closed nuclear fuel cycle, where spent nuclear fuel is reprocessed to recover valuable materials for reuse in future reactors. The remaining high-level radioactive waste is immobilised and safely stored, reducing waste and supporting India's three-stage nuclear power programme.

As India continues to grow and develop, its nuclear energy programme will play a vital role in supporting economic growth, environmental sustainability, and long-term energy security. By harnessing the power of nuclear energy, India is building a secure and resilient energy future, one that is powered by innovation, sustainability, and self-reliance.
