We most often see uranium-235 and plutonium-239 used as nuclear fuels.
uranium and plutonium
U235
The most common fuels used in nuclear chain reactions are 235U (uranium) and 239Pu (plutonium).
The most common isotope of uranium is uranium-238.
Nuclear fission.
208Po, 209Po, 210Po
The word expectation is not adequate; uranium is used as fuel in nuclear power reactors. Nuclear energy is the most important alternative for fossil fuels.
The most important isotopes for nuclear reactors are: - fissile isotopes: U-233, U-235, Pu-239, Pu-241 - fertile isotopes: Th-232, U-238
The most common fuels used in nuclear chain reactions are 235U (uranium) and 239Pu (plutonium).
in reactors: yellowcake, a uranium oxide; after that probably metallic uraniumin stars: ordinary hydrogen; after that helium
The most common fossil fuels are coal, oil and natural gas.
The isotopes 252Cf and 251Cf.

The most common isotope of uranium is uranium-238.
Plutonium exist in nuclear fuels (burned or new fuels of the type U-Pu).
69 and 67
Uranium and most transuranic elements. Plutonium and Americium are particularly good reactor fuels.
