Overview of India’s Nuclear Power Sector
As of March 2023, India’s nuclear power capacity stands at 6.78 GW, contributing approximately 3% to the country’s total electricity generation (Central Electricity Authority, 2023). The government aims to expand this capacity to 22.5 GW by 2031, reflecting a strategic push to enhance energy security and meet climate commitments (Draft National Electricity Plan, 2023). This expansion is spearheaded by the Department of Atomic Energy (DAE), with a budget allocation of INR 3,000 crore for FY 2023-24 (Union Budget 2024). India’s nuclear power tariffs, ranging between INR 2.50-3.00 per unit, remain competitive against coal-based power tariffs of INR 3.50-4.00 (CEA Tariff Report, 2023).

Legal Framework Governing Nuclear Energy in India
The Atomic Energy Act, 1962 is the foundational statute regulating atomic energy in India. Sections 3 and 4 vest exclusive authority in the central government for the development, control, and use of atomic energy, effectively centralizing nuclear governance. The Environment Protection Act, 1986 (Section 3) empowers the central government to regulate environmental hazards, including radiation risks, which affects nuclear project clearances. The Civil Liability for Nuclear Damage Act, 2010 (Section 6) defines the liability limits of nuclear operators, establishing a distinct regime from general industrial liability laws and thereby addressing compensation in case of nuclear accidents.
Supreme Court rulings, such as those interpreting environmental clearance requirements (drawing from principles in the Niyamgiri case), have underscored the necessity of rigorous environmental impact assessments (EIA) for nuclear projects. These judicial interventions have introduced procedural complexity, often causing project delays.
Institutional Architecture and Coordination Challenges
India’s nuclear power ecosystem comprises several key institutions. The Department of Atomic Energy (DAE) oversees research, development, and policy. The Nuclear Power Corporation of India Limited (NPCIL) operates nuclear power plants. The Atomic Energy Regulatory Board (AERB) is the statutory authority responsible for nuclear safety and radiation protection. The Bhabha Atomic Research Centre (BARC) focuses on technology development. The International Atomic Energy Agency (IAEA) facilitates international safety standards and cooperation. The Central Electricity Authority (CEA) integrates nuclear power into overall electricity planning.
However, regulatory fragmentation persists. AERB’s mandate overlaps with state environmental agencies during project clearances, causing coordination inefficiencies. Unlike France’s centralized regulatory model under the Autorité de sûreté nucléaire (ASN), India’s fragmented oversight slows decision-making and complicates compliance.
Economic Considerations and Resource Constraints
India’s nuclear power expansion requires an estimated investment of USD 20 billion for new reactors by 2031 (IAEA India Country Report, 2023). Despite competitive tariffs, India is heavily dependent on uranium imports, sourcing about 90% from Kazakhstan, Canada, and Australia (DAE Annual Report, 2023). Indigenous uranium reserves are limited, constraining fuel security.
The current nuclear share of 3% in India’s energy mix contrasts sharply with countries like France, where nuclear accounts for approximately 70% of electricity generation, supported by standardized reactor designs and centralized procurement, leading to cost and operational efficiencies.
| Parameter | India | France |
|---|---|---|
| Nuclear Capacity (GW) | 6.78 (2023) | ~63 |
| Share in Electricity Generation | 3% | 70% |
| Regulatory Authority | AERB (fragmented with state agencies) | ASN (centralized) |
| Uranium Source | 90% imported | Domestic + imports |
| Tariff (INR/unit) | 2.50-3.00 | Comparable, stable tariffs |
Barriers to Scaling Nuclear Power
- Fuel Security: Limited domestic uranium reserves force reliance on imports, exposing India to supply risks.
- Regulatory Complexity: Overlapping jurisdiction between AERB and environmental/state bodies delays clearances.
- Project Delays: Stringent environmental impact assessments and public opposition extend timelines.
- Technological Gaps: India’s reactor fleet includes older designs; need for advanced reactors and fuel cycle technologies.
- Liability Concerns: The Civil Liability for Nuclear Damage Act’s unique provisions have complicated foreign vendor participation.
Way Forward for India’s Nuclear Power Transformation
- Legal Reforms: Streamline environmental clearance processes by harmonizing AERB and state agency roles to reduce delays.
- Fuel Strategy: Expand domestic uranium exploration and invest in thorium-based reactors to reduce import dependency.
- Institutional Coordination: Establish a unified nuclear regulatory authority to centralize safety and environmental oversight, emulating France’s ASN model.
- Technological Innovation: Accelerate development of indigenous advanced reactors (e.g., AHWR) and closed fuel cycle technologies at BARC.
- International Cooperation: Engage with IAEA and nuclear supplier countries to secure fuel supply and technology transfer under safeguards.
- It places unlimited liability on nuclear plant operators in case of an accident.
- It creates a distinct liability regime separate from general industrial laws.
- It defines liability limits for suppliers and vendors involved in nuclear projects.
Which of the above statements is/are correct?
- India’s nuclear power contributes approximately 10% to the total electricity generation.
- The target is to increase nuclear capacity to 22.5 GW by 2031.
- Current nuclear tariffs are higher than coal-based power tariffs.
Which of the above statements is/are correct?
Jharkhand & JPSC Relevance
- JPSC Paper: Paper 3 (Science and Technology), Paper 2 (Governance and Environment)
- Jharkhand Angle: Jharkhand hosts uranium mining sites (e.g., Jaduguda), making nuclear fuel supply relevant to the state’s economy and energy policy.
- Mains Pointer: Discuss Jharkhand’s uranium resources, environmental concerns of mining, and the state’s role in national nuclear energy expansion.
What is the role of the Atomic Energy Regulatory Board (AERB) in India?
The AERB is the statutory authority responsible for regulating nuclear safety and radiation protection in India. It oversees licensing, inspection, and enforcement related to nuclear facilities and radiation sources.
Why is India dependent on uranium imports despite having domestic reserves?
India’s domestic uranium reserves are limited and of lower grade, insufficient to meet growing demand. Hence, India imports about 90% of uranium from countries like Kazakhstan, Canada, and Australia to fuel its reactors.
How does the Civil Liability for Nuclear Damage Act, 2010 differ from general liability laws?
The Act creates a separate liability regime specifically for nuclear damage, limiting the liability of operators and suppliers, and establishing a no-fault liability principle to ensure timely compensation without protracted litigation.
What are the key barriers to nuclear power expansion in India?
Key barriers include limited domestic uranium, complex environmental clearance processes, fragmented regulatory oversight, technological gaps, and liability concerns that deter foreign participation.
How does France’s nuclear power model differ from India’s?
France operates a centralized regulatory system (ASN), standardized reactor designs, and has a dominant nuclear share (~70%) in electricity generation, enabling stable tariffs and low emissions. India’s model is fragmented, with only 3% nuclear share and reliance on imported uranium.
