Expert Answer:

Uranium 235 and Plutonium 239 are the most fissile elements. They react quickly when bombarded with neutrons.
 
Also, they produce enough new neutrons for the fission process to continue further.
 
Other radioactive elements also can be used as nuclear fuel, however they are very radioactive and can cause severe danger while producing energy.
 
Another reason for these two fuels to be used prominently is their availability on Earth. They are available on Earth abundantly as compared to other elements.
