  • 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.
