The Pros And Cons Of Thorium

Thorium is the nuclear fuel that should have been. Thorium has many advantages over uranium but was and most likely will never be used as a nuclear fuel source. There is only one primary reason thorium was never used as a nuclear fuel source - this reason is wartime politics. There are also reasons we aren’t going to make a switch anytime soon. These reasons include our lack of experience with Thorium, the amount of money it would take to convert uranium nuclear reactors to thorium (or build new reactors), and lack of infrastructure in place for thorium. However, other countries are investing heavily on thorium. India is planning to handle 30% of their electrical needs with thorium in the near future. China is also heavily investing with the same general plan - 30% dependency.

Uranium dependent nuclear power began fairly early. In WW2, during the end of the war, uranium had to be processed into plutonium 239. Uranium is a fissile, radioactive metal with a half life of 4.5 billion years. In a nuclear reactor, uranium 238 goes to uranium 239 which decays into neptunium 239 - 23.5 minutes - to plutonium 239 - 2.36 days. The plutonium created in this process is the plutonium that was used in the Fat Man bomb. The source of fuel used for the Little Boy bomb was …show more content…

Thorium is about 3.3 times as common as uranium. The Earth’s crust is made up of 0.0006% thorium as opposed to 0.00018% uranium. Almost all thorium found in the Earth’s crust is thorium 232 - the desirable kind for a reactor. The major source of the thorium extracted is from monazite phosphate. Monazite phosphate contains cerium, neodymium, lanthanum, and of course phosphorus and oxygen. Monazite phosphate is typically 3-5% thorium dioxide. Most of the world’s current demand for thorium comes from Malabar Coast in india where monazite is deposited. Extracting the thorium from the monazite uses standard mining equipment and
