Thorium resources are the estimated mineral reserves of thorium on Earth. Thorium is a future potential source of low-carbon energy. [1] Thorium has been demonstrated to perform as a nuclear fuel in several reactor designs. [2] [3] It is present with a higher abundance than uranium in the crust of the earth. Thorium resources have not been ...
The preceding reserve figures refer to the amount of thorium in high-concentration deposits inventoried so far and estimated to be extractable at current market prices; millions of times more total exist in Earth's 3 × 10 19 tonne crust, around 120 trillion tons of thorium, and lesser but vast quantities of thorium exist at intermediate ...
Monazite powder, a rare earth and thorium phosphate mineral, is the primary source of the world's thorium. India's three-stage nuclear power programme was formulated by Homi Bhabha, the well-known physicist, in the 1950s to secure the country's long term energy independence, through the use of uranium and thorium reserves found in the monazite sands of coastal regions of South India.
Two radiometric dating methods involve thorium isotopes: uranium–thorium dating, based on the decay of 234 U to 230 Th, and ionium–thorium dating, which measures the ratio of 232 Th to 230 Th. [e] These rely on the fact that 232 Th is a primordial radioisotope, but 230 Th only occurs as an intermediate decay product in the decay chain of ...

Countries by natural gas proven reserves (2014), based on data from The World Factbook. Natural gas is a widely available fossil fuel with estimated 850 000 km 3 in recoverable reserves and at least that much more using enhanced methods to release shale gas. Improvements in technology and wide exploration led to a major increase in recoverable ...
India is developing this technology, motivated by substantial thorium reserves; almost a third of the world's thorium reserves are in India, which lacks significant uranium reserves. The third and final core of the Shippingport Atomic Power Station 60 MWe reactor was a light water thorium breeder, which began operating in 1977. [17]
The ultimate focus of the programme is on enabling the thorium reserves of India to be utilised in meeting the country's energy requirements. Thorium is particularly attractive for India, as it has only around 1–2% of the global uranium reserves, but one of the largest shares of global thorium reserves at about 25% of the world's known ...
