Difference Between Thorium and Uranium

Thorium is more abundant in nature than uranium. It is fertile rather than fissile, and can only be used as a fuel in conjunction with a fissile material such as recycled plutonium. Thorium fuels can breed fissile uranium-233 to be used in various kinds of nuclear reactors.

Is thorium better than uranium?

Thorium is three times more abundant in nature than uranium. ... Compared to uranium reactors, thorium reactors produce far less waste and the waste that is generated is much less radioactive and much shorter-lived.

Why Thorium is a bad idea?

Irradiated Thorium is more dangerously radioactive in the short term. The Th-U cycle invariably produces some U-232, which decays to Tl-208, which has a 2.6 MeV gamma ray decay mode. Bi-212 also causes problems. These gamma rays are very hard to shield, requiring more expensive spent fuel handling and/or reprocessing.

Is thorium safer than uranium?

Thorium is safer and more efficient to mine than uranium, thus making it more environmentally friendly. ... It is estimated that one ton of thorium can produce as much energy as 35 tons of uranium in a liquid fluoride thorium reactor.

Is Thorium more radioactive than uranium?

Thorium is three to four times more abundant than uranium. ... Liquid fluoride thorium reactors (LFTR) have very little waste compared with reactors powered by uranium. LFTRs run at atmospheric pressure instead of 150 to 160 times atmospheric pressure currently needed. Thorium is less radioactive than uranium.

Can thorium replace uranium?

Thorium can also be used to breed uranium for use in a breeder reactor. ... Put very simply, thorium can be used together with conventional uranium-based nuclear power generation, meaning a thriving thorium industry would not necessarily make uranium obsolete.

How harmful is thorium?

Thorium is radioactive and can be stored in bones. Because of these facts it has the ability to cause bone cancer many years after the exposure has taken place. Breathing in massive amounts of thorium may be lethal. People will often die of metal poisoning when massive exposure take place.

Which country has most thorium?

Australia has the highest thorium resources with 489,000 tons followed by the US with 400,000 tons, Turkey with 344,000 tons and India with 319,000 tons. The remaining resources are found in countries like Venezuela, Brazil, Norway, Egypt, Russia, among others.

Can thorium be used for nuclear power?

Thorium cannot in itself power a reactor; unlike natural uranium, it does not contain enough fissile material to initiate a nuclear chain reaction. As a result it must first be bombarded with neutrons to produce the highly radioactive isotope uranium-233 – 'so these are really U-233 reactors,' says Karamoskos.

Can thorium power the world?

Between 1999 and 2021, the number of operational thorium reactors in the world has risen from zero, to a handful of research reactors, to commercial plans for producing full-scale thorium-based reactors for use as power plants on a national scale.

Is thorium named after Thor?

In 1815, for example, Berzelius isolated a new element from a mineral sent to him from the Swedish mining town of Falun and named it thorium after the Scandinavian god of thunder, Thor.

Can thorium be weaponized?

Although some wonder if thorium can be used in nuclear weapons and are concerned about the possibility of a thorium bomb, thorium actually can't be weaponized because it doesn't produce enough recoverable plutonium, which is required for building nuclear weapons.

Can you buy thorium?

Thorium is a common element widely distributed across the earth and typically concentrated in the heavy sands which serve as ores for the rare earth metals. Look high, look low and nowhere can a person buy a gram or two of this “common” metal. ...
