India's ambition to achieve a 100 GWe nuclear power capacity by 2047 hinges significantly on the effective utilization of its vast thorium reserves. Despite possessing one of the largest thorium deposits globally, the country faces considerable technological and economic hurdles that must be addressed to realize this vision. The integration of thorium into India's energy framework is not merely a matter of resource management but a strategic imperative for energy security and sustainability. As the world increasingly shifts towards cleaner energy sources, thorium presents a viable alternative that could help India meet its growing energy demands while minimizing environmental impact.

Institutional and Legal Framework

• The SHANTI Act 2025 aims to streamline India's nuclear energy development, focusing on thorium utilization.
• The Department of Atomic Energy (DAE) oversees thorium research and development, emphasizing its role in the three-stage nuclear program.
• The Atomic Energy Act, 1962, provides the legal framework for nuclear energy production, including thorium-based technologies.
• International collaborations, particularly with the International Atomic Energy Agency (IAEA), enhance research capabilities in thorium reactors.

India’s Thorium Reserves

• India possesses an estimated 150,000 tons of thorium, making it one of the most resource-rich countries in this regard (Source: Atomic Minerals Directorate for Exploration and Research).
• Over 70% of these reserves are concentrated in Kerala and Odisha (Source: DAE).
• The three-stage nuclear program is designed to transition from uranium to thorium-based reactors by 2050, targeting a generation capacity of 300 GWe (Source: DAE Report 2022).
• Challenges: Extracting thorium from ores is energy-intensive and generates significant waste, necessitating advanced reactor technology and economic viability assessments.

Need for Thorium Utilization

• Reduce Reliance on Imports: India's nuclear generation capacity is heavily dependent on imported uranium, which poses risks related to supply disruptions.
• Sustainability of Uranium Production: As global nuclear capacity is projected to increase from 380 GWe to 1,400 GWe by 2047, the sustainability of uranium resources becomes a pressing concern.
• Energy Security: Thorium can provide a stable and long-term energy source, minimizing risks associated with geopolitical tensions affecting uranium supply.
• Environmental Benefits: Thorium-based reactors produce less long-lived radioactive waste compared to traditional uranium reactors, contributing to a cleaner environment.

Key Challenges

• Technological Barriers: The absence of advanced reactor designs specifically for thorium utilization hampers progress.
• Economic Viability: High initial costs and the need for significant investment in research and infrastructure pose challenges to thorium adoption.
• Public Perception: Nuclear energy, including thorium, faces skepticism from the public due to safety concerns and environmental impact perceptions.
• Regulatory Framework: Existing regulations may not adequately address the unique aspects of thorium-based nuclear technology, necessitating updates to the legal framework.
• Research and Development: Limited funding and resources for thorium research can slow down technological advancements.

Critical Evaluation

The current trajectory of thorium utilization in India reveals significant gaps in both policy and execution. While the potential for thorium to contribute to energy security is substantial, the lack of advanced reactor technology and economic feasibility studies poses a critical barrier to
