Investing in Thorium

It is likely that thorium's use will continue to decline unless a lowcost disposal process is developed or new technology, such as a nonproliferative nuclear fuel, creates renewed demand. On the basis of data through September 2010, the average value of imported thorium compounds decreased to per kilogram from the 2009 average of per kilogram (gross weight).

Use of thorium232 progeny to determine thorium activity

Use of thorium232 progeny to determine thorium activity

As you know, the longlived thorium decays initially to 228 Ra, which has a year halflife, the longest lived of all the radioactive progeny that follow. Thus, in a pure sample of 232 Th, if no physical or chemical processes are ongoing that would disturb the 232 Th 228 Ra equilibrium, it would require about 35 years before the 228 Ra achieved about the same activity as the 232 Th.

 · Thorium power works differently as nearly all fuel gets consumed as it is generated. When the process shuts down, that is it. Only the radioactivity that is en route so to say will have to be accounted for, not everything generated thus far in the process. The difference is about 10000 to one in the size of the problem.

 · I think the claim that thorium reactors are more proliferation resistant has to do with the fact that the process of converting thorium to uranium 233 also results in generating uranium 232. Uranium 232 is quite easy to detect from large distances, which makes it undesirable for nuclear weapons (, it is too easy to find them).

 · Abstract. In nature, thorium exists mainly in a monoisotopic form with no fissile isotope for its use as fuel in nuclear reactors. Though a fissile isotope of uranium, 233 U is formed by neutron irradiation of fertile thorium in reactors; the subsequent reprocessing of irradiated thorium for recovery, purifiion, and further handling of 233 U product (accompanied by 232 U) has remained a ...

What Is Thoriated Tungsten Used For?

 · Thoriated tungsten was and still is a mainstay in tungsten inert gas (TIG) arc welding due to the predictability it brings to the TIG welding process and to welds. However, its major drawback is that it is mildly radioactive. The majority of thorium's radiation is released in the form of alpha particles.
