India’s Nuclear Power Promise by 2047
 
Overview
 
India is embarking on an ambitious journey to transform its energy landscape, making nuclear power a cornerstone of its strategy for clean, reliable, and long-term energy security. As of 2025, the government has set a visionary target to scale up nuclear power capacity from the current 8.8 GW to 100 GW by 2047, positioning nuclear energy as integral to the goals of national development, net-zero emissions, and energy independence.
 
Key Elements of India’s Nuclear Power Promise
 
1. Ambitious Capacity Targets

• Current capacity: 8,880 MW (8.88 GW) from 25 reactors at seven stations.
• Short-term target: 22,480 MW (~22.5 GW) by 2031-32, involving the construction of 18 new reactors (13,800 MW) and expanding existing sites.
• Long-term target: 100 GW by 2047—a more than tenfold increase—marking a transformative leap in India’s energy mix.

 
2. Union Budget 2025–26 Initiatives

• Introduction of a Nuclear Energy Mission, supported by a ₹20,000 crore outlay for R&D, focused especially on Small Modular Reactors (SMRs).
• Roadmap to develop at least five indigenously designed and operational SMRs by 2033.
• Strong emphasis on leveraging India’s expertise in Pressurized Heavy Water Reactor (PHWR) technology and initiating private sector participation through policy reforms.

 
3. Policy and Legislative Reforms

• Plans to amend the Atomic Energy Act, 1962 and Civil Liability for Nuclear Damage Act (CLNDA), 2010 to facilitate joint ventures with the private sector and attract foreign investment.
• Introduction of incentives such as green power classification, long-term financing, and tax concessions to make nuclear tariffs more competitive.
• Greater transparency and a streamlined regulatory process to speed up project approvals and execution.

 
4. Technology and Project Pipeline

• Progressive technology adoption including SMRs and Fast Breeder Reactors (FBRs) to diversify and decentralize the nuclear grid.
• Collaboration with international partners such as France and the United States for advanced modular and large reactor projects.
• Focus on domestic reactor development—PHWRs and next-gen reactors—across multiple states, including Rajasthan, Tamil Nadu, Haryana, Karnataka, Madhya Pradesh, and Andhra Pradesh.

• Small Modular Reactors (SMRs) and Bharat Small Reactors (BSRs): India is standardizing 220 MW PHWR designs for BSRs to rapidly deploy clean energy to replace aging thermal plants, and is targeting five indigenously developed SMRs operational by 2033.
• 700 MW PHWR Expansion: Streamlining approvals, land acquisition, and supply chains for large-scale 700 MW reactor projects is critical to meet short- and medium-term targets.

 
5. Safety, Sustainability, and Net-Zero Commitments

• Continued adherence to stringent safety standards and international best practices, with all reactors operating under close oversight to ensure environmental and public safety.
• Nuclear’s critical role in India’s commitment to achieve net-zero carbon emissions by 2070, providing stable, non-fossil energy to a growing population and industrial economy.

 
Challenges and Way Forward
 

• Historical capacity ramp-up has lagged behind earlier targets, requiring a significant acceleration of project execution and investment to reach 100 GW by 2047.
• Legal and policy reforms are crucial for greater private and foreign participation.
• Sustained public communication and community engagement are needed to build confidence in nuclear safety and technology.

 
India’s Nuclear Power Journey
 
Early Beginnings (1947–1960)

• India entered the nuclear age soon after gaining independence in 1947.
• In 1948, the Atomic Energy Commission (AEC) was established with Homi Jehangir Bhabha, regarded as the father of India’s nuclear program, as its first chairman. 
• The program focused initially on peaceful uses of nuclear energy, with Prime Minister Jawaharlal Nehru strongly endorsing atomic energy for development and modernization.
• The early years saw construction of research facilities such as the Bhabha Atomic Research Centre (BARC) at Trombay (started in 1954), the Indian equivalent of Los Alamos for nuclear research. India received international assistance, notably from Canada (which supplied the CIRUS reactor in 1960) and the United States (heavy water supply), under the “Atoms for Peace” program.

 
First Nuclear Reactors (1960s–1970s)
 

• In 1963-64, India planned its first nuclear power plant in Rajasthan, modeled on the Canadian Douglas Point reactor, leading to the Rajasthan Atomic Power Plant (RAPP-1) which began operation in 1972.
• Simultaneously, India was developing indigenous capability, designing pressurized heavy water reactors (PHWRs), which remain the backbone of its nuclear fleet.
• India’s first nuclear explosion—dubbed a “peaceful nuclear explosion”—was conducted in 1974 at Pokhran, signaling its entry into the nuclear weapons club and leading to withdrawal of international support for civilian nuclear cooperation.

 
Self-Reliance and Expansion (1980s–1990s)
 
After 1974, India pursued nuclear power development with limited foreign cooperation:
 

• The country expanded reactor capacity mainly through indigenous PHWR technology.
• Work began on advanced facilities such as the Fast Breeder Reactor (FBR) to tap its abundant thorium reserves, with the Prototype Fast Breeder Reactor (PFBR) at Kalpakkam as the centerpiece.
• India conducted further nuclear tests in 1998, reaffirming its strategic nuclear capability but complicating international cooperation.

 
Post-2005: Indo-US Nuclear Deal and Global Engagement
 
The 2005 123 Agreement between India and the US marked a watershed moment:
 

• It ended India’s nuclear isolation by allowing civil nuclear trade despite India not being a signatory to the Nuclear Non-Proliferation Treaty (NPT).
• This opened new avenues for international partnerships, technology acquisition, and fuel supply.
• India committed to expanding civilian nuclear power capacity and modernizing its regulatory and safety frameworks.
