Last week, when the first-of-its-kind thorium-based fuel developed by a firm in the United States—Clean Core Thorium Energy (CCTE)—achieved a 45 GigaWatt-days per Metric Ton (GWd/MTU) burn-up level at the US Department of Energy’s Idaho National Laboratory, it was not only a breakthrough with potential to redefine the future of nuclear energy, now dependent on uranium. The development is significant for India, too.
