Uranium and Thorium | Australia's Energy Commodity …

Uranium and thorium are naturally occurring elements that are widespread in the Earth's crust. Mining occurs in locations where such elements are naturally concentrated. To produce nuclear fuel from uranium ore, the uranium is extracted from the host rock and then the 235U isotope is progressively enriched.

The thorium fuel cycle (shown above) starts with the transmutation of 232 Th into 233 U through a series of decays. 233 U goes on to play the role of nuclear fuel in these reactors. The thorium fuel cycle also produces plutonium, but the non-weaponizable isotope (plutonium-238). 233 U can also be used in nuclear weapons, but the presence …

The fission energy of 233 U is 190 MeV and that of 239 Pu is 200 MeV. If 1 kg of thorium were bred into 233 U, the fission energy available would be 78.9 × 10 12 J thermal (78.9 TJ th).The fission energy in 1 kg of natural uranium, bred to 239 Pu, is 80.4 TJ th.Thus thorium and uranium are quite similar in maximum energy content, but …

A comparison of analytical methods for determining uranium and thorium

For the latter method, uranium and thorium were separated using anion exchange resin filled in a column. The results show that overall a sample mass of 0.1–0.5 g with addition of 20 mL concentrated nitric acid is the most efficient means for extracting uranium and thorium simultaneously from apatite ore, black schist and mill tailings. The ...

The diagram in Fig. 1 shows the global average distribution of energy resources over the major mineral energy sources: hydrocarbons, uranium, thorium, and lithium-6. Global thorium resources are assumed at a level of 6 million tons []; however, according to the content of thorium in the Earth's crust, the volume of thorium natural …

What's the Difference Between Thorium and Uranium …

In the three-phase plan for efficiently using thorium, a uranium-fueled reactor consumes U-235 and as it fissions it generate neutrons that are absorbed in U-238 to create Pu-239. The Pu-239 is ...

Thorium

Thorium as a nuclear fuel. Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is 'fertile' and upon absorbing a neutron will transmute to uranium-233 (U-233) a, which is an excellent fissile fuel material b. In this regard it is similar to uranium-238 (which transmutes to plutonium ...

Both thorium and uranium-238 require two neutrons to release their energies. One neutron converts them into a fissile form and the other neutron actually causes the fission.
