Why Is Thorium, A Potentially Safer Alternative To Uranium

2 days ago&ensp·&enspSince the fission of thorium doesn't produce plutonium (one of the elements used in nuclear weapons) as a byproduct, uranium, the dualpurpose nuclear fuel, took precedence. However, nations have finally begun to understand the safety aspects of thorium as a nuclear fuel and have started developing thoriumbased nuclear reactors.

Thorium As Nuclear Fuel: the good and the bad

202031&ensp·&enspThorium is a basic element of nature, like Iron and Uranium. Like Uranium, its properties allow it to be used to fuel a nuclear chain reaction that can run a power plant and make electricity (among other things). Thorium itself will not split and release energy. Rather, when it is exposed to neutrons, it will undergo a series of nuclear
