Discuss the recent steps taken by the Government of India to promote nuclear technology for civilian energy purposes. What are the key challenges — technological, regulatory, and financial — that continue to hinder its full potential?

India's current installed nuclear capacity is approximately 8.78 GW, contributing about ~3% to the country's total electricity generation. India has set an ambitious target to achieve 100 GW of nuclear power capacity by 2047.

Recent government steps to promote Civilian Nuclear Energy:

• Legislative Reform and Private Participation:
  • The

SHANTI Act, 2025, modernises India’s nuclear legal framework and permits controlled private participation in nuclear facilities, fuel fabrication and R&D.

• The Act strengthens the role of the Atomic Energy Regulatory Board (AERB) and introduces a graded civil liability framework (replacing the uniform liability cap with a flexible, risk-based system) to reduce legal uncertainty for domestic and global partners.
• Nuclear Energy Mission and Financial Backing:
  • The Nuclear Energy Mission was announced with an allocation of ₹20,000 crore for R&D and deployment of Small Modular Reactors (SMRs). At least five indigenous SMRs are targeted by 2033.
  • The mission supports Bharat Small Reactors (BSRs) for captive industrial power, brownfield sites and decentralised energy use.
• Indigenous Technology and Next-Generation Reactors:
  • BARC is developing indigenous designs such as BSMR-200, SMR55 and a high-temperature gas-cooled reactor for hydrogen production.
  • The 500 MWe Prototype Fast Breeder Reactor (PFBR) at Kalpakkam has successfully attained first criticality, marking India's successful transition into Stage II of its three-stage nuclear program.
• Fleet-Mode Expansion: The government is promoting standardised 700 MWe Pressurised Heavy Water Reactors (PHWRs) through a “fleet mode” approach to reduce project delays, lower costs, and scale up indigenous nuclear capacity faster.
• International
• Cooperation: India has civil nuclear cooperation arrangements with 18 countries for technology access, uranium supply and reactor collaboration.
• Land and Infrastructure Support: The government is exploring nuclear deployment at brownfield sites, including existing nuclear sites and retired thermal power plant locations. This aims to reduce land acquisition delays and support the repurposing of coal-based infrastructure.

Nuclear power is being promoted as a low-carbon, reliable baseload source to complement solar and wind.

Key Challenges hindering India’s Nuclear Energy Potential:

• Technological Challenges:
• Uranium constraint and delayed thorium transition: India has limited domestic uranium but large thorium reserves. However, Stage III of the Three-Stage Nuclear Programme, based on thorium, remains distant.
• Fast breeder delays: The PFBR at Kalpakkam is crucial for Stage II and future thorium utilisation, but it has faced long technological and commissioning delays.
• Slow reactor execution: Large reactors involve complex engineering, specialised components and supply-chain dependence, leading to delays and cost escalation.
• Limited SMR experience: India is developing SMRs such as BSMR-200 and SMR-55, but commercial-scale deployment is still untested.
• Water and climate stress: Inland nuclear plants require reliable cooling water. Water scarcity and high summer temperatures can affect cooling efficiency and plant output.
• Human resource gap: Scaling to 100 GW by 2047 will require a much larger pool of trained nuclear engineers, safety experts, reactor operators and regulatory specialists.
• Waste and decommissioning: Spent fuel handling, radioactive waste storage and safe decommissioning remain technically sensitive.
• Safety culture: As private players enter the sector, India must ensure that expansion does not dilute nuclear safety standards.
• Regulatory and Legal Challenges:
• Civil liability concerns: Historically, supplier liability under CLNDA (2010), especially the operator’s right of recourse, discouraged foreign vendors such as Westinghouse and Framatome.
• Legacy state monopoly: The Atomic Energy Act, 1962 restricted nuclear power largely to the state. New reforms, such as the SHANTI Act, 2025, aim to allow controlled private participation, but implementation will take time.
• Regulatory credibility: India needs a regulator that is technically strong, visibly independent and trusted by citizens.
• Land acquisition and public resistance: Projects such as Jaitapur have faced delays due to local concerns over safety, displacement and environmental impact.
• Clearance delays: Environmental approval, site selection, emergency planning and inter-agency coordination slow down project execution.
• Security and safeguards: Nuclear material accounting, non-proliferation obligations, waste control and physical security require strict state oversight.
• Financial Challenges:
• High upfront cost: Nuclear plants require heavy capital investment and have long gestation periods.
• Cost and tariff uncertainty: Delays, imported components and construction risks make tariffs uncertain and private financing difficult.
• Competition from renewables: Solar and wind are cheaper, so nuclear must be valued for baseload power, grid stability and low-carbon reliability, not only for tariff comparison.
• Green finance limitations: India’s Sovereign Green Bond Framework excludes nuclear power generation, limiting access to some low-cost green capital.
• Long-term liabilities: Fuel cycle management, safety upgrades, waste storage and decommissioning require assured funding across decades.
• Private investment risk: Investors need clarity on liability, regulation, offtake agreements, tariff recovery and government support.

India’s nuclear ambitions are strong, but realising 100 GW by 2047 will require faster reactor execution, credible regulation, liability clarity, public trust, skilled manpower, climate-resilient siting and innovative financing.
