Quick Revision: The SHANTI Act, 2025, restructures India’s nuclear liability regime and permits private participation in select nuclear activities, while the Nuclear Energy Mission allocates ₹20,000 crore for Small Modular Reactors (SMRs) to accelerate India’s low-carbon power generation capacity.

Why is this in the news?

The article highlights India’s renewed emphasis on nuclear energy as a critical component of its decarbonisation strategy, marked by legislative reforms such as the SHANTI Act, 2025, and the launch of the Nuclear Energy Mission with a ₹20,000 crore allocation for Small Modular Reactors (SMRs). This development is significant in the context of India’s ambitious target of achieving 100 GW of nuclear capacity by 2047, despite historical constraints like technology restrictions and liability concerns, and the global resurgence of nuclear power as a low-carbon energy source amid climate imperatives.

Background

• Nuclear energy contributes approximately 3.1% to India’s electricity mix, with an installed capacity of 8.78 GW, significantly lower than the global average share of low-carbon electricity.
• India’s nuclear programme has evolved under self-reliance due to its exclusion from the Non-Proliferation Treaty (NPT) following its 1974 and 1998 nuclear tests, leading to the development of a three-stage nuclear programme leveraging indigenous resources like thorium.
• The India-US Civil Nuclear Agreement (2008) facilitated international cooperation by lifting technology restrictions, though India’s nuclear liability regime remained a deterrent for foreign suppliers.
• Post-Fukushima (2011), India implemented stringent safety upgrades and reassessed its nuclear liability framework, culminating in the SHANTI Act, 2025, which restructures liability and permits private participation in select nuclear activities.
• The global resurgence of nuclear energy is driven by the need for reliable, low-carbon baseload power to complement variable renewable sources like solar and wind, particularly as grids decarbonise.
• India’s net-zero target by 2070 and the projected surge in electricity demand from electrification of transport, industry, and buildings necessitate a diversified energy mix, including nuclear power.

What is the SHANTI Act, 2025, and the Nuclear Energy Mission?

• The SHANTI Act, 2025, is a legislative reform that restructures India’s nuclear liability framework, replacing the single liability cap with a graded liability system to balance operator and supplier responsibilities.
• The Act permits private sector participation in select nuclear activities—such as construction, operation, and maintenance of nuclear power plants—under stringent licensing by the Atomic Energy Regulatory Board (AERB), while retaining central control over sensitive areas like uranium enrichment, spent-fuel management, and heavy-water production.
• The Nuclear Energy Mission, launched alongside the SHANTI Act, allocates ₹20,000 crore for the development and deployment of Small Modular Reactors (SMRs), with a target of at least five indigenous SMR units by 2033.
• SMRs are advanced nuclear reactors designed for modular construction, scalability, and enhanced safety, making them suitable for deployment in remote or industrial areas with lower grid capacity.
• The Mission aims to accelerate India’s nuclear capacity expansion by leveraging private investment, indigenous technology, and international collaborations, while addressing historical constraints like liability uncertainties and technology restrictions.
• The reforms are aligned with India’s three-stage nuclear programme, which envisages a gradual shift from uranium-based reactors to thorium-based reactors, utilising India’s abundant thorium reserves for long-term energy security.
• The Act also strengthens institutional frameworks for nuclear safety, waste management, and public disclosure, addressing concerns arising from incidents like Chernobyl and Fukushima.
• The policy shift reflects a broader global trend of re-evaluating nuclear energy as a viable low-carbon option, particularly in regions with high energy demand and limited land or water resources for large-scale renewables.

Key Features

Feature	Significance
Low-carbon electricity generation	Provides consistent, large-scale power with minimal greenhouse gas emissions, critical for decarbonising energy systems.
Energy density	Nuclear fuel contains millions of times more energy per unit mass than fossil fuels, enabling compact and high-output power generation.
Grid stability	Operates independently of weather conditions, complementing variable renewable sources like solar and wind.
Long operational lifespan	Nuclear reactors typically operate for 40–60 years, offering long-term energy security.
Technological diversity	India’s three-stage nuclear programme leverages uranium, plutonium, and thorium, ensuring fuel security.

Why it Matters

Economic

• Capital-intensive sector with high upfront costs but low operational costs, requiring long-term financing and risk mitigation.
• Indigenous nuclear industry can reduce import dependence in energy and technology, fostering self-reliance.
• Potential to create high-skilled jobs in engineering, manufacturing, and regulatory oversight.

Strategic

• Enhances energy security by diversifying the power mix, reducing reliance on fossil fuel imports.
• Supports India’s net-zero by 2070 commitment by providing a reliable, scalable low-carbon energy source.
• Strengthens strategic autonomy through indigenous nuclear technology development and fuel cycle control.

Environmental

• Substantially reduces carbon emissions compared to coal or gas, aligning with climate mitigation goals.
• Minimises land use per unit of electricity generated compared to solar or wind farms.
• Manages radioactive waste through regulated storage and reprocessing, though public perception remains a hurdle.

Technological

• Advancements in small modular reactors (SMRs) can enable decentralised, flexible nuclear power deployment.
• Integration with renewables in hybrid systems improves grid resilience and reliability.
• Innovations in fuel technology (e.g., thorium utilisation) can extend fuel resources and reduce waste.

Challenges

1. Public Perception and Trust

• Historical nuclear accidents (Chernobyl, Fukushima) create enduring public fear of radiation and safety risks.
• Lack of transparency in safety assessments and incident reporting can erode trust in regulatory bodies.
• Need for sustained public engagement and education to distinguish between perceived and actual risks.

2. Regulatory and Institutional Capacity

• Complex regulatory framework due to dual control (central and state) in nuclear energy governance.
• Shortage of skilled nuclear professionals, including engineers, scientists, and safety inspectors.
• Need for independent, transparent institutions to oversee safety, waste management, and liability.

3. Financial and Economic Viability

• High capital expenditure and long gestation periods deter private investment despite policy incentives.
• Cost overruns and delays in project execution (e.g., Kudankulam) undermine economic feasibility.
• Competition with cheaper renewables and fossil fuels in short-term energy markets.

4. Technological and Fuel Constraints

• Dependence on imported uranium due to limited domestic reserves, despite thorium reserves.
• Limited indigenous capacity for heavy-water production and fuel enrichment under international restrictions.
• Challenges in scaling thorium-based reactors within the three-stage programme timeline.

6. Policy and Legal Framework

• Ambiguity in liability regimes (e.g., Civil Liability for Nuclear Damage Act) deters foreign suppliers.
• Need for harmonised state and central policies to facilitate nuclear project approvals and land acquisition.
• Balancing international non-proliferation obligations with domestic energy security goals.
