This invention was made by an American company in the nuclear tech, set up by a person of Indian origin.
This company has developed a fuel, which is a mix of Thorium and Uranium of a certain level of enrichment, called HALEU (High Assay Low Enriched Uranium).
Clean Core calls this concoction ANEEL (Advanced Nuclear Energy for Enriched Life).
ANEEL can be used in the existing Pressurized Heavy-Water Reactors (PHWRs).
PHWR is an indigenous reactor system that is the workhorse of India’s nuclear fleet.
India has 18 PHWR reactors of a total capacity of 4,460 MW and is building ten more of 700 MW each.
Most of the current reactors run on uranium fuel enriched up to 5 per cent Uranium-235.
HALEU is Uranium enriched to more than 5 per cent but less than 20 per cent.
At present only Russia and China have the infrastructure to produce HALEU at scale.
India has the world’s largest reserves of Thorium, estimated at 1.07 million tonnes, enough to last over a century.
If India uses this Thorium, it can then produce enough green energy and easily turn net-zero by its target date of 2070.
However, Thorium is a fertile material and not a fissile material.
This means, it must be paired with Uranium-235 or Plutonium-239 to be used as fuel in a reactor.
