Coming Soon For decades, uranium has been the primary fuel used in commercial nuclear reactors. However, another element—thorium—has attracted growing attention as a potential fuel for future generations of nuclear power. Thorium is more abundant than uranium and is found in significant quantities in countries such as India, Australia, Brazil, and the United States. Many scientists believe that thorium-based fuel cycles could offer advantages in terms of fuel availability, safety, and waste management. India’s long-term nuclear strategy is particularly noteworthy because it includes a dedicated third stage designed to utilise the country’s vast thorium resources. While thorium has yet to achieve widespread commercial deployment, it remains one of the most promising areas of research in advanced nuclear technology. This comprehensive article is currently under development and will explore the science, opportunities, challenges, and future prospects of thorium as a nuclear fuel.
