Why Is Thorium, A Potentially Safer Alternative To Uranium ...

Feb 16, 2020· The pioneering research & development in the nuclear domain was performed with the purpose of creating nuclear weapons. Since the fission of thorium doesn't produce plutonium (one of the elements used in nuclear weapons) as a byproduct, uranium, the dual-purpose nuclear fuel took precedence. However, nations have finally understood the safety aspects of thorium as a nuclear fuel …

Thorium Energy vs Uranium Energy - Nuclear Power

Thorium 232. Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays via alpha decay into 228 Ra .
