Thorium Reactor - Thorium Power Plant - Nuclear Power
Thorium 232 Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in nature. This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons, and its half-life is considerably longer than the age of Earth. Therefore 232 Th belongs to primordial nuclides.
