Uranium and Thorium Nuclear Power Plants - A Comparative Study

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. Another more recent innovation is to use a seed and blanket system which has a central core of rods surrounded by a blanket.

Thorium - Wikipedia

Ionium–thorium dating is a related process, which exploits the insolubility of thorium (both 232 Th and 230 Th) and thus its presence in ocean sediments to date these sediments by measuring the ratio of 232 Th to 230 Th. Both of these dating methods assume that the proportion of 230 Th to 232 Th is a constant during the period when the ...

thorium | Description, Properties, & Uses | Britannica.com

Natural thorium is a mixture of radioactive isotopes, predominantly the very long-lived thorium-232 (1.40 × 10 10-year half-life), the parent of the thorium radioactive decay series. Other isotopes occur naturally in the uranium and actinium decay series, and thorium is present in all uranium ores.
