Why Thorium Is Not Used In Nuclear Reactors?
Thorium-based reactors are safer because the reaction can easily be stopped and because the operation does not have to take place under extreme pressures. Compared to uranium reactors, thorium reactors produce far less waste and the waste that is generated is much less radioactive and much shorter-lived.

Thorium Reactor
According to the World Nuclear Association, there are seven types of reactors that can be designed to use thorium as a nuclear fuel. Six of these have all entered into operational service at some point (usually with uranium fuel). The most promising are, for example: Heavy water reactors (PHWRs).

Could Thorium Power the Next Generation of Nuclear Reactors?
There are several ways thorium could be applied to energy production. One way under investigation now is to use solid thorium/uranium-232 fuel in a conventional water-cooled reactor, similar to modern uranium-based power plants. In fact, more than 20 reactors world-wide have been operated with fuel made of thorium and uranium-233.

Thorium Reactors: Solving the Global Energy Crisis
The reactor core of an LFTR, illustrated in Fig. 2, is comprised of a uranium salt core surrounded by a 'fertile' liquid thorium salt blanket. The reactor operates at a temperature of roughly 650˚C. The fuel core is composed of molten lithium fluoride, beryllium fluoride, and uranium tetrafluoride [2]. The uranium is the fissile material ...

Thorium
Thorium (Th-232) is not itself fissile and so is not directly usable in a thermal neutron reactor. However, it is 'fertile' and upon absorbing a neutron will transmute to uranium-233 (U-233)a, which is an excellent fissile fuel materialb. In this regard it is similar to uranium-238 (which transmutes to plutonium-239). All …

Thus, thorium is a better 'fertile' material than 238U in thermal reactors but thorium is inferior to depleted uranium as a 'fertile' material in fast reactor. • For the 'fissile' 233U nuclei, the number of neutrons liberated per neutron absorbed (represented as η) is greater than 2.0 over a wide range of thermal neutron spectrum,
