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.
A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
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 ...
The thorium fuel cycle is a nuclear fuel cycle that uses an isotope of thorium, 232 Th, as the fertile material. ... [21] although present knowledge of reserves is ...
Thorium reserves significantly exceed those of uranium, and of course hydrogen is abundant. It is also considered by many to be easier to obtain than uranium . While uranium mines are enclosed underground and thus very dangerous for the miners, thorium is taken from open pits, and is estimated to be roughly three times as abundant as uranium in ...
The IAEA's 2005 report estimates India's reasonably assured reserves of thorium at 319,000 tonnes, but mentions recent reports of India's reserves at 650,000 tonnes. [21] A government of India estimate, shared in the country's Parliament in August 2011, puts the recoverable reserve at 846,477 tonnes. [22]
