· Thorium can generate more fissile material (uranium-233) than it consumes while fuelling a water cooled or molten salt reactor, and it generates fewer long-lived minor actinides than plutonium fuels. It is estimated that the Earth’s upper crust contains an average of 10.5 parts per million (ppm) of thorium, compared with about 3

· Nuclear Energy: Thorium is considered an alternative nuclear fuel due to its potential in thorium reactors, where it undergoes neutron absorption to become fissile uranium-233 (U-233). Thorium reactors could offer several advantages over traditional uranium reactors, including greater fuel efficiency, reduced production of long-lived

Uranium–thorium dating. Uranium–thorium dating, also called thorium-230 dating, uranium-series disequilibrium dating or uranium-series dating, is a radiometric dating technique established in the 1960s which has been used since the 1970s to determine the age of calcium carbonate materials such as speleothem or coral.
