India has installed nuclear capacity of around 8,180 MW. With the government aiming to triple this capacity to 22,480 MW by 2031-2032, the debate centers on balancing India’s soaring base-load energy demands with the strategic, financial, and environmental complexities of nuclear expansion.
Need to Keep Expanding the Nuclear Energy Programme
Reliable Base-Load Power: Unlike intermittent solar and wind energy, nuclear plants operate at very high capacity factors (85-90%).
Supports Net-Zero Goals: Nuclear energy is a low-carbon source that helps reduce dependence on coal and supports India’s 2070 Net-Zero and Glasgow Panchamrit commitments.
Advancing the Three-Stage Programme: With the PFBR at Kalpakkam attaining criticality, India can progress toward thorium-based long-term energy security.
Low Land Requirement: Nuclear plants generate large amounts of electricity within a compact area, unlike extensive solar parks and wind farms.
Private Investment through the SHANTI Act: Allows regulated private and foreign participation, including up to 49% equity in civilian nuclear projects.
Commercialization of SMRs: India aims to operationalize indigenous Small Modular Reactors (SMRs) like the Bharat SMR-200 by 2033, offering lower costs and enhanced safety.
Ensures Grid Stability: Nuclear power provides stable base-load support essential for integrating large-scale renewable energy into the national grid.
Enhances Strategic Autonomy: Post-2008 NSG waiver, nuclear expansion strengthens India’s geopolitical standing and civil nuclear partnerships with countries like France, Russia, and the United States.
Employment: The sector boosts advanced manufacturing and skilled employment through firms like Bharat Heavy Electricals Limited and Larsen & Toubro under the Make in India initiative.
Fears and Challenges Associated with Nuclear Energy
Import Dependence in Supply Chains: Despite progress in domestic manufacturing, India still relies on imports for critical high-precision nuclear components and instrumentation.
Financial and Market Risks: High capital costs, long payback periods, tariff uncertainty, and lack of assured long-term PPAs reduce investor confidence in nuclear projects.
Public Resistance and Safety Concerns: Projects like Kudankulam Nuclear Power Plant and Jaitapur have witnessed protests over radiation fears and displacement.
Regulatory Uncertainty for SMRs: The absence of a dedicated regulatory framework for Small Modular Reactors (SMRs) creates uncertainty for new technology developers.
Concerns over Supplier Liability: Changes under the SHANTI Act reducing supplier liability have raised concerns about weakening accountability and quality control standards.
The “Act of God” Indemnity Gap: The SHANTI Act indemnifies operators for accidents caused by “grave natural disasters” marking a shift away from India’s traditional absolute liability principle.
Fear of Nuclear Disasters: Incidents such as the Chernobyl disaster and Fukushima Daiichi nuclear disaster continue to shape public anxiety regarding reactor safety.
Radioactive Waste Disposal: Safe long-term storage of high-level radioactive waste remains technologically and politically challenging worldwide.
Security Vulnerabilities: Nuclear facilities face risks from cyberattacks, sabotage, drone strikes, and other asymmetric security threats. Eg- Kudankulam Plant Malware attack.
Land Acquisition: Environmental concerns, local protests, and legal disputes continue to delay projects at sites like Jaitapur and Kovvada.
Water Use and Thermal Pollution: Reactors require large quantities of cooling water, while discharge of heated water can harm nearby aquatic ecosystems.
Human Capital Crisis: Declining academic interest has led many institutions, including IIT, Madras and IIT Bombay, to discontinue nuclear engineering programmes.
Supply Chain and Execution Bottlenecks: Domestic suppliers face cash-flow shortages, skilled labour gaps, and quality compliance issues, causing delays in NPCIL’s fleet-mode construction projects.
Way Forward
Dedicated SMR Regulatory Framework: The Atomic Energy Regulatory Board should create a specialized framework for SMRs to accelerate safe commercialization.
Develop Innovative Financing Mechanisms: Eg- Long-term low-interest financing, green bonds, Viability Gap Funding (VGF), and specialized insurance mechanisms.
Strengthen Domestic Supply Chains: Should expand fleet-mode procurement and support domestic industries in producing advanced nuclear components to reduce import dependence and project costs.
Ensure Independent Nuclear Regulation: The Atomic Energy Regulatory Board must be given greater functional and financial autonomy to ensure credible safety oversight.
Revive Nuclear Talent Pipelines: Support nuclear engineering programmes through scholarships, research grants, and assured internships to build skilled manpower.
Expand the Indian Nuclear Insurance Pool (INIP): Strengthening INIP through General Insurance Corporation of India can provide better coverage for accident liability.
With the SHANTI Act and the Kalpakkam breakthrough, India has gained strong momentum for nuclear expansion. Effective implementation can help build a sustainable, self-reliant, and resilient clean energy future.
