Concept:

Nuclear Fission Reactor

A device in which nuclear chain reactions are initiated, controlled and, sustained at a steady rate is called a nuclear fission reactor.
It works on the principle of controlled chain reaction and provides energy at a constant rate.
The phenomenon was discovered by French physicist Francis Perrin in 1972.

Explanation:

Nuclear reactors are large kettles, in which heating of water take-place to produce enormous amounts of low-carbon electricity.
Such reactors are come in different sizes and shapes and can be powered by a variety of different fuels.
Fuels used in the nuclear reactor
Different materials can be used to fuel a reactor, but the most commonly used fuel is uranium.
Other fuels such as plutonium and thorium can also be used.
A typical reactor requires about 27 tonnes of fresh fuel each year.

Among the given list, the fuel used in nuclear fission reactor is Thorium.
