• With a rapidly increasing population and industrialization, the country’s energy demand is expected to double by 2040.
• Due to its low carbon footprint and high energy output, nuclear power offers a reliable solution for meeting future energy requirements while supporting global climate commitments.
• India’s three-stage nuclear program, focusing on uranium, plutonium, and thorium, reflects a long-term vision for achieving energy self-sufficiency.
• Nuclear technology is widely used for power generation, defense applications, space exploration, medical advancements, and food preservation.

Current Status of Nuclear Energy in India

• Civil Nuclear Power: 

• • • Operational Nuclear Power Plants: India has 22 functioning nuclear reactors with a total installed capacity of 7,480 MW (as of 2024).
    • Upcoming Projects: Several reactors are currently under construction, including Kudankulam (Units 3-6), Gorakhpur Haryana Anu Vidyut Pariyojana, and Kaiga Units 5 & 6. These projects are expected to increase nuclear capacity by nearly 7,000 MW in the coming decade, reaching 22,480 MW by 2031.
    • Indigenous Reactor Technology: India has developed its own Pressurized Heavy Water Reactors (PHWRs) and Prototype Fast Breeder Reactor (PFBR) while also advancing thorium-based Advanced Heavy Water Reactors (AHWRs).

• Nuclear in Defense: 

• • • Nuclear-Powered Submarines: India has developed INS Arihant, its first indigenous nuclear-powered ballistic missile submarine (SSBN), with work underway on INS Arighat and additional units.
    • Nuclear-Capable Missiles: The country has developed a range of nuclear-capable missiles, including Agni (I-V), Prithvi, and K-15 (Sagarika).
    • Strategic Forces Command (SFC) manages India’s nuclear arsenal, ensuring credible deterrence under the No First Use (NFU) policy.

• Nuclear Research and Collaborations: 

• • • India collaborates with the International Atomic Energy Agency (IAEA), Russia (Rosatom), and the US (under the 123 Agreement) for nuclear technology development and exchange.
    • Significant domestic research is conducted at institutions like Bhabha Atomic Research Centre (BARC), Indira Gandhi Centre for Atomic Research (IGCAR), and Nuclear Power Corporation of India Limited (NPCIL).

• Technologies in Use and Development: 

• • Pressurized Heavy Water Reactors (PHWRs): These reactors form the core of India’s nuclear power program, using natural uranium as fuel.
  • Fast Breeder Reactors (FBRs): The 500 MWe Prototype Fast Breeder Reactor (PFBR) is under development to utilize plutonium and thorium.
  • Molten Salt Reactors (MSRs): These reactors are still in the research phase, with a focus on thorium utilization.
  • Small Modular Reactors (SMRs): India is exploring SMRs for potential deployment at decommissioned coal plant sites.

Importance of Nuclear Energy

• Energy Security: 

• • • India’s three-stage nuclear program is designed to maximize the use of thorium reserves, ensuring long-term energy independence.
    • Currently, nuclear power contributes around 3% of India’s electricity generation, with a target to reach 22% by 2050.

• Clean Energy and Climate Goals: 

• • • As a low-carbon energy source, nuclear power supports India’s Net Zero goal for 2070.
    • It provides base-load power, complementing renewable energy sources and maintaining grid stability.

• Strategic and Scientific Advancements: 

• • Nuclear technology plays a critical role in space exploration (radioisotope thermoelectric generators for deep-space missions).
  • It enhances India’s defense capabilities by supporting nuclear deterrence and second-strike capability.
  • Nuclear applications in medicine and agriculture support healthcare and food security.

Government Initiatives to Promote Nuclear Energy

• Three-Stage Nuclear Program: 

• • • Stage 1: Development of PHWRs using natural uranium as fuel.
    • Stage 2: Expansion of Fast Breeder Reactors (FBRs) utilizing plutonium and thorium.
    • Stage 3: Transition to Thorium-based reactors, ensuring sustainable energy generation.

• Bharat Small Reactors (BSR) and Private Sector Involvement: 

• • • Aims to develop and deploy Small Modular Reactors (SMRs) with private sector participation.
    • Encouraging companies like L&T, Tata, and Reliance to invest in nuclear infrastructure.

• International Collaborations and Policy Reforms: 

• • Indo-US Nuclear Deal: Enabled India to access global uranium markets and advanced nuclear technologies.
  • Civil Nuclear Cooperation Agreements: Signed with Russia, France, the USA, and Japan for fuel supply and technology transfer.
  • Nuclear Insurance Pool (2016): Established to manage financial risks associated with nuclear energy projects.

Challenges in the Development of Nuclear Energy

• Technological and Infrastructure Challenges: 

• • • High Initial Costs: Nuclear power plants require substantial investment, making them more expensive than coal or renewable energy sources.
    • Limited Indigenous Uranium Supply: India relies on imported uranium, affecting energy security.
    • Project Delays: Key projects, including Kudankulam and PFBR, have experienced repeated delays.

• Safety and Environmental Concerns: 

• • • Radiation Risks: Public concerns over nuclear safety, especially after the Fukushima disaster, affect public acceptance.
    • Nuclear Waste Management: India currently lacks a long-term strategy for safe disposal of nuclear waste.

• Regulatory and Political Issues: 

• • • Public Opposition: Resistance from local communities in Tamil Nadu and Maharashtra has delayed nuclear projects.
    • Policy Uncertainty: Frequent changes in nuclear regulations hinder private sector participation.

• Geopolitical Constraints: 

• • Nuclear Suppliers Group (NSG) Membership: India’s non-signatory status to the NPT restricts access to advanced nuclear technologies.
  • Global Uranium Market Fluctuations: Dependence on imported uranium makes India vulnerable to price and supply chain fluctuations.

Future Strategies for Advancing Nuclear Energy

• Accelerate Thorium-Based Reactor Development to utilize India’s vast thorium reserves.
• Encourage Private Sector Participation to drive technological innovation and investment.
• Improve Public Awareness to gain community support for nuclear projects.
• Strengthen Global Collaborations for fuel security and technology transfer.
• Develop Small Modular Reactors (SMRs) to expand energy access.
• Enhance Nuclear Waste Management with deep geological repositories.
• Leverage AI and Digital Tools to improve reactor safety and efficiency.
