Thorium is a naturally occurring radioactive element that is found in large quantities across India, especially in regions like Kerala and Odisha. Its significance is rooted in its potential as a sustainable energy source, as it is more abundant than uranium and produces considerably less nuclear waste during energy production.
While thorium itself is not fissile and cannot sustain a nuclear chain reaction, it must first be converted into Uranium-233 using a nuclear reactor. Once this conversion occurs, Uranium-233 serves as a viable fuel for generating nuclear power.
The Prototype Fast Breeder Reactor located at Kalpakkam in Tamil Nadu has successfully undergone testing to demonstrate the feasibility of utilizing thorium. This reactor is a crucial component of India’s ambitious three-stage nuclear power program, which aims to harness the country's thorium reserves and achieve energy self-sufficiency.
Thorium presents India with an opportunity to lessen its reliance on imported uranium. By advancing the technology necessary to utilize its abundant thorium resources, India can work towards a more sustainable and self-sufficient nuclear energy future.
India actively engages in various international forums under the International Atomic Energy Agency (IAEA) to enhance its research and development initiatives in thorium technology. However, it does remain outside certain multilateral collectives that focus solely on thorium-based systems.
Thorium reactors are promoted as a cleaner nuclear technology due to their generation of fewer long-lived radioactive wastes compared to traditional uranium reactors. This characteristic can significantly contribute to minimizing the environmental footprint associated with nuclear power.
In conclusion, thorium stands as a beacon of sustainability for India’s nuclear energy ambitions, promising a cleaner, more self-reliant energy future.
