List of the Pros of a Thorium Reactor. 1. It eliminates the threat of nuclear weapons. Although a standard thorium reactor is fueled uranium-233 isotope, there is no need for uranium enrichment with this technology. That means the malicious step to modify energy fuel into a nuclear weapon goes away with this technology.

Thorium exists almost entirely as 232 Th which has a half-life of 14 050 million years. From its natural state, 232 Th decays through a number of stages to eventually form 208 Pb, which is stable.The main difference is that thorium is far less mobile than uranium in oxidising surface conditions (Mernagh and Miezitis, 2008).

232 Th is the predominant isotope of natural thorium. If this fertile material is loaded in the nuclear reactor, the nuclei of 232 Th absorb a neutron and become nuclei of 233 Th.The half-life of 233 Th is approximately 21.8 minutes. 233 Th decays (negative beta decay) to 233 Pa (protactinium), whose half-life is 26.97 days. 233 Pa decays (negative beta …
