It is advised that India should pursue research and development on thorium instead of Uranium as the future fuel of nuclear energy. What advantages does the thorium hold over uranium?
1, 2 and 4
Thorium fuel is a bit harder to prepare. Thorium dioxide melts at 550 degrees higher temperatures than traditional Uranium dioxide, so very high temperatures are required to produce high-quality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process. This is irrelevant for fluid-fueled reactors discussed below.
Thorium cycles exclusively allow thermal breeder reactors (as opposed to fast breeders). More neutrons are released per neutron absorbed in the fuel in a traditional (thermal) type of reactor. This means that if the fuel isreprocessed,
