However, thorium must be used together with U-233, at least in the start-up stage, to produce energy in the thorium fuel cycle. Neutron can trigger a fission reaction in U-233, resulting in 2 fission products and 2 or 3 neutrons. When hit by a neutron, Thorium-232 is transmuted to Thorium-233, which then quickly decays to Protactinium-233.Web

Currently, there is little demand (and industrial need) for thorium; it is obtained mostly as a by-product from the production of rare earth metals or from the production of titanium-, zirconium-, or tin-bearing minerals from monazite deposits. 16 Little systematic exploration has therefore been conducted specifically for thorium, which explains the relative …Web

Ilmenite was used in drilling operations in the North Sea in 1979 and 1980. The ilmenite was a fairly coarse ground material compared to the presently used ilmenite.
