Thorium 232 - an overview | ScienceDirect Topics

Thorium. The only gaseous product in the thorium decay series is thoron, which has a very short half-life (56 s). It can be used to determine 220 Rn, and also its parent, 232 Th. Thorium is determined by comparison with a standard, but because of the short half-life of 220 Rn, decay correction must be made.

Kirk Sorensen: An Update On The Thorium Story | Peak ...

Aug 31, 2014· It is a basically different process than what we do today, and much more sustainable—not just because thorium is so much more abundant but because of the efficiency of which the thorium has to be utilized in the reactor. And so that really separates it. in addition, the thorium technology is best realized when it is used in what is called a ...

Thorium As Nuclear Fuel: the good and the bad

Thorium fuel is a bit harder to prepare. Thorium dioxide melts at 550 degrees higher temperatures than traditional Uranium dioxide, so very high temperatures are required to produce high-quality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process. This is irrelevant for fluid-fueled reactors discussed below.
