WebThorium as a nuclear fuel. Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is ‘fertile’ and upon absorbing a neutron will transmute to uranium-233 (U-233) a, which is an excellent fissile fuel material b. In this regard it is similar to uranium-238 (which transmutes to plutonium ...
WebJul 20, 2024 · During this process, some of the natural thorium is converted into the isotope proactinium-230. The protactinium-230 decays into uranium-230, which further decays to form an isotope of the element thorium, thorium-226. Both of these isotopes, uranium-230 and thorium-226, have potential for use in radiopharmaceuticals.
