India Accelerates Nuclear Ambitions with SMR Development Targeting 100 GW by 2047
In a significant policy announcement, India's Minister of Atomic Energy Jitendra Singh has revealed the nation's ambitious plan to construct five small modular reactor (SMR) units domestically by 2033. This strategic initiative represents a crucial step in accelerating nuclear power deployment over the next two decades, aligning with India's long-term energy development roadmap.
India's Comprehensive SMR Development Strategy
According to Minister Singh, the five SMR units will form an integral component of India's nuclear energy strategy, with the goal of increasing installed capacity from the current 8.78 GW to approximately 22 GW by the financial year 2031-32. This plan was outlined in a written response to lawmakers as reported by local media outlets.
The Bhabha Atomic Research Centre (BARC) - India's premier nuclear research facility under the Department of Atomic Energy - is currently developing three reactor types:
- Bharat Small Modular Reactor 220 MW
- A 55 MW reactor
- A high-temperature gas-cooled reactor designed for hydrogen production
Long-term Development Roadmap to 2047
India has set an ambitious target of increasing nuclear power installed capacity to 100 GW by 2047, representing more than an 11-fold increase from the current 8.8 GW. To achieve this objective, a committee established by India's Ministry of Power has estimated that cumulative investment of ₹19.28 lakh crore (approximately $200 billion at current exchange rates) will be required.
The "roadmap to 100 GW" report published last year emphasized the importance of energy diversification to meet the nation's growing demand while reducing dependence on fossil fuels.
| Timeline | Capacity Target (GW) | Growth vs Current |
|---|---|---|
| Financial Year 2031-32 | 22 | Approximately 150% increase |
| Year 2047 | 100 | Over 1,000% increase |
Liberalization of the Nuclear Energy Sector
In late 2025, the Indian government approved the landmark Atomic Energy Act, marking the first time private companies can invest in the nuclear energy industry. This legislation, known as the SHANTI Act (Sustainable Harnessing of Advancement of Nuclear Energy for Transforming India), is expected to attract significant private sector investment into the nuclear energy sector.
However, in the context of opening up to private sector participation, the state-owned NTPC Ltd - India's largest power utility - will maintain a crucial role. NTPC is projected to account for 30% of new nuclear power capacity by 2047.
Currently, NTPC is India's only nuclear power producer and is actively seeking to acquire stakes in global uranium resources to secure fuel supplies for the anticipated expansion of the country's nuclear power capacity.
Advantages of Small Modular Reactors
Small Modular Reactors (SMRs) are increasingly viewed as the future of nuclear energy with several advantages over traditional nuclear power plants:
- Smaller footprint with flexible installation options
- Lower initial construction costs
- Shorter construction timelines
- Scalable modular design
- Enhanced safety with passive safety systems
The development of indigenous SMR technology not only helps India diversify its energy sources but also demonstrates the country's advanced technological capabilities in civilian nuclear applications.
Impact on National Energy Strategy
The development of nuclear energy, particularly SMR technology, is expected to play a pivotal role in India's long-term energy strategy. With an increasingly large population and rising energy demands, reducing dependence on fossil fuels remains a top priority.
Furthermore, nuclear energy will help India meet its commitments to reduce greenhouse gas emissions while ensuring energy security in the context of increasingly unstable global fossil fuel supplies.
Current Nuclear Energy Landscape in India
India currently operates 22 nuclear power reactors with a total installed capacity of 8.78 GW, generating approximately 3.2% of the country's electricity. The government aims to increase nuclear power's share in the electricity mix to 9% by 2047 as part of its broader clean energy transition.
The nation's nuclear program has historically faced challenges including uranium supply constraints, international sanctions, and technology access limitations. However, recent advancements in domestic technology development and international cooperation have opened new pathways for expansion.
Global Context for SMR Development
Globally, SMRs are gaining traction as countries seek flexible, cost-effective nuclear energy solutions. The International Atomic Energy Agency (IAEA) has identified SMRs as a key technology for the future of nuclear energy, with over 70 SMR designs under development worldwide.
India's focus on SMR technology places it among several nations including the United States, China, Russia, and Canada that are investing heavily in next-generation nuclear solutions. The successful development and deployment of SMRs could position India as a leader in nuclear technology innovation.
Conclusion: A New Era for Indian Nuclear Power
India's ambitious plan to develop SMR technology and increase nuclear power capacity to 100 GW by 2047 demonstrates a strong commitment to energy diversification and reduced fossil fuel dependence. With support from domestic technology development and private sector investment, India is on track to become a nuclear energy powerhouse in the coming decades.
However, challenges regarding uranium supply, nuclear security, and waste management must be addressed to ensure sustainable development of the country's nuclear energy sector. The successful implementation of this roadmap could transform India's energy landscape while contributing to global climate goals.
