Introduction: A Nuclear Vision for Viksit Bharat@2047

As India marches toward its ambitious goal of becoming a developed nation by 2047, energy security stands as a pivotal pillar in the vision of Viksit Bharat. Amid the global climate crisis and rising energy demands, nuclear power has re-emerged as a compelling solution. India’s commitment to achieving 100 GW of nuclear power capacity by 2047 is both visionary and necessary—but achieving this requires a strategic shift in policy, participation, and international cooperation.

While India’s nuclear energy sector has traditionally been a tightly controlled domain under government monopoly—primarily led by the Department of Atomic Energy (DAE) and Nuclear Power Corporation of India Limited (NPCIL)—it is now imperative to welcome private sector investments and foreign partnerships. A reformed nuclear ecosystem can unlock the full potential of atomic energy as a clean, reliable, and scalable contributor to India’s net-zero aspirations.

Current Landscape: A Modest Yet Strategic Beginning

India currently operates 23 nuclear reactors with a total installed capacity of 7.48 GW, which contributes around 3% to the national power grid. While this share is relatively small compared to other energy sources, the significance of nuclear energy lies in its baseload capacity, zero-carbon footprint, and energy independence.

India’s three-stage nuclear power program, envisioned by Dr. Homi Bhabha, is designed to harness the country’s vast thorium reserves. The three stages involve:

  1. PHWRs (Pressurized Heavy Water Reactors) using natural uranium

  2. Fast Breeder Reactors (FBRs) using plutonium from reprocessed spent fuel

  3. Thorium-based reactors to tap into India's extensive thorium deposits

Tarapur’s Power Reactor Fuel Reprocessing Plant (PREFRE), established in 1970, was the first major milestone in the back-end fuel cycle strategy, making India one of the few nations with full-cycle nuclear fuel capabilities.

Need for Speed: Why India Must Accelerate Nuclear Deployment

India’s power demand is projected to nearly double by 2047. The government estimates that to meet the growing base-load energy requirement while decarbonizing the grid, nuclear power must scale up to at least 100 GW, contributing approximately 10-12% of total electricity generation.

Key drivers pushing this transition include:

  • Climate change commitments under the Paris Agreement

  • Net Zero Emissions by 2070 pledge by Prime Minister Narendra Modi

  • Energy independence and diversification

  • Growing industrial and urban demand

  • The need to replace retiring coal plants

But current policies and pace of execution will not get India even halfway there. The average gestation period of a nuclear power plant in India is 12–15 years due to regulatory, legal, and supply chain hurdles. Unless there is policy liberalization, foreign technology partnerships, and private sector involvement, the 100 GW target will remain a distant dream.

Global Cooperation: Tapping the Civil Nuclear Market

India’s entry into the global civil nuclear community post the 2008 Indo-U.S. Civil Nuclear Agreement and waiver from the Nuclear Suppliers Group (NSG) opened the door for technology transfer and uranium imports. However, progress has been sluggish.

Key international partnerships that can catalyze India’s nuclear roadmap:

  • U.S.-India civil nuclear partnership via Westinghouse and GE-Hitachi small modular reactors (SMRs)

  • France’s EDF collaboration on European Pressurized Reactors (EPRs) at Jaitapur

  • Russia’s Rosatom involvement in Kudankulam reactors

  • Australia and Canada as reliable uranium suppliers

  • Japan’s technology and component manufacturing expertise

India must push for strategic agreements that go beyond fuel supply to include joint ventures, local manufacturing under Make in India, capacity building, and safety training.

Private Sector Participation: A Policy Bottleneck

India’s Atomic Energy Act, 1962, prohibits private players from operating nuclear reactors or even investing in nuclear power generation. While companies like Larsen & Toubro, BHEL, and Tata Projects contribute to nuclear component manufacturing, their role is limited to EPC contracts and not core operations.

To accelerate capacity addition:

  • Amendments in Atomic Energy Act must be considered to allow private equity under regulation

  • Creation of a nuclear energy regulator independent from AERB/DAE

  • Establishment of Nuclear Parks under PPP model

  • Boost indigenous SMR manufacturing with private sector capabilities

  • Time-bound single-window clearance mechanisms

The current centralized approach cannot meet decentralized energy demand. A federal nuclear framework involving states and industry can create synergy, speed, and scale.

Small Modular Reactors (SMRs): Game Changer for Clean Power

One of the most exciting global developments in nuclear power is the rise of Small Modular Reactors (SMRs)—compact, factory-built, and scalable nuclear reactors with enhanced safety.

India, with its space and energy constraints, is ideally positioned to benefit from SMRs for:

  • Urban and industrial clusters

  • Remote areas with no grid connectivity

  • Hydrogen production hubs

  • Desalination plants in coastal states

NPCIL and BARC have initiated preliminary studies on SMRs, but the absence of a clear regulatory roadmap and public-private cooperation has hindered progress. India's startup ecosystem and engineering talent can play a vital role if the sector is opened up.

Safety, Waste Management & Public Trust: Addressing the Elephant in the Room

Nuclear energy still faces opposition due to public safety concerns, especially after events like Fukushima and Chernobyl. In India, protests at Kudankulam, Jaitapur, and other sites have delayed commissioning by years.

India must invest heavily in:

  • Public awareness campaigns

  • Transparent risk communication

  • Strengthening the Atomic Energy Regulatory Board (AERB)

  • Waste management strategy using reprocessing and vitrification

  • Liability mechanisms under Civil Liability for Nuclear Damage Act, 2010

Modern reactor designs like Generation IV and passive safety features must be incorporated to enhance public trust.

The Role of India’s Strategic Autonomy and Clean Tech Diplomacy

India’s pursuit of nuclear energy also has geopolitical and strategic dimensions:

  • Strategic autonomy from oil and gas imports

  • Reducing dependence on volatile fossil fuel markets

  • Climate diplomacy leadership in Global South

  • Carbon-free baseload for green hydrogen economy

India must position itself as a responsible nuclear power and promote South-South cooperation for nuclear technology transfer, especially to countries in Africa and Southeast Asia with similar energy challenges.

What Needs to Be Done: Policy Recommendations

  1. Amend Atomic Energy Act to allow regulated private participation

  2. Fast-track SMR development with public-private partnerships

  3. Simplify land acquisition and environment clearances for nuclear projects

  4. Set up a sovereign nuclear innovation fund for R&D in thorium, Gen-IV reactors, and AI-based safety systems

  5. Restructure NPCIL and DAE to separate commercial and regulatory functions

  6. Formalize long-term uranium import deals with diversified suppliers

  7. Create a transparent nuclear waste management authority

  8. Incentivize nuclear in clean energy finance, such as green bonds or Viability Gap Funding (VGF)

Conclusion: The Tipping Point for India's Nuclear Renaissance

India’s nuclear energy program stands at a historic crossroad. With climate urgency, growing demand, and strategic imperatives, the country cannot afford to keep nuclear power sidelined. A bold and reformative approach—one that blends technology, trust, and teamwork—can redeem the promise that India’s nuclear pioneers envisioned decades ago.

With a well-executed roadmap, India can not only meet its 100 GW nuclear capacity target by 2047 but also become a global leader in clean energy innovation and sustainable development.

The atom, once a symbol of destruction, now holds the promise of light, life, and leadership—for a cleaner, greener, and more secure India.
