Why aren't Thorium reactors being utilized? Much safer,

All other advantages of a "thorium reactor" basically comes from the molten salt reactor, which can run fine on uranium as well. In fact, all molten salt reactor designs within 10 years of commercialisation are meant to run on uranium, because sorting out the regulations behind onsite processing is going to take too long for LFTRs to make a meaningful impact on climate change.

APS Physics

2020/8/28In 1943, Wigner and Weinberg also conceived a liquid fuel thorium-uranium breeder reactor, for which the aqueous reactor discussed above was but the first step. The fundamental premise in such a reactor is that a blanket of thorium Th-232 surrounding the fissile core will absorb neutrons, with some nuclei thus being converted ("transmuted") to Th-233.

Thorium is more abundant in the earth's crust than uranium and thus could be used for longer without being depleted. However, it behaves sufficiently differently to uranium to need a different reactor design, which comes with some technical considerations. Get price

Thorium reactor: Terrorism environmentally friendly

In any thorium reactor, the naturally occurring 232Th is irradiated with neutrons from fissile material (for example, 235U, 233U or 239Pu). Some of the thorium nuclei capture a neutron and become 233Th. This isotope then undergoes beta decay to 233Pa which Get price

Thorium

Thorium is a chemical element with symbol Th and atomic number 90. Thorium metal is silvery and tarnishes black when exposed to air, forming the dioxide; it is moderately hard, malleable, and has a high melting point.Thorium is an electropositive actinide, whose chemistry is dominated by the +4 oxidation state; it is quite reactive, prone to ignition on air when finely divided.

Uranium and Thorium Nuclear Power Plants

There are several design systems for thorium reactors, some using a first stage reactor to irradiate the thorium, and further processing it to Th-233, before using it in a thorium reactor.

Thorium, the Next Nuclear Fuel?

It makes sense too, given that thorium requires no pre-processing and produces reactor-grade Uranium as its primary byproduct. By using the Uranium as well (which they have found difficult to import) they extend the life of the cores out to two years, which is practically unheard of. Get price

Thorium 232 is not fissile, that means it can't split and create power. Thorium 232 needs a uranium reactor to get it started by sending out neutrons that the thorium 232 can absorb. When that happens, the thorium 232 changes to U233, which is fissile. So Get price
