A fuel rod is a metal tube (zirconium alloy) that contains fuel pellets in bundles (stacks). Fuel pellets vary in composition, but most consist of uranium and/or plutonium in some form. One type is uranium dioxide powder that has been compressed and heated to form a ceramic. Zirconium is used as a container because it has low neutron absorption, and allows the neutron radiation being produced by the fuel to escape into the surrounding reactor core so it can do its work of heating water to make steam that drives the power plant turbines.
The size of a fuel rod depends on the type of fuel and the application. A CANDU fuel rod, for example, may be 50 cm long and 10 cm in diameter.
fossil fuel is made by the nature and nuclear fuel is not made by the nature
The fuel rods used in a nuclear reactor are made from uranium 235(U-235).

Nuclear fuel is the fuel used to produce nuclear energy.
For example plutonium is a nuclear fuel; also the isotope 233U.
We usually find that uranium is used as fuel in nuclear reactors (though some use plutonium).
Usually, the rods themselves are made of Uranium-238. The fuel inside the rods is Uranium-235, which is highly fissionable. The Uranium-238 is very heavy, and slows down the neutrons so that they can properly strike the U-235 atoms.
Nuclear power is NOT a fossil fuel.
what possible future nuclear fuel
Uranium is the fuel for nuclear energy. In most reactors it is used in the form of uranium dioxide, UO2, which is made into small cylinders 10mm diameter, and loaded into tubes made of zircaloy which are then sealed. A number of these tubes are then made up into a fuel assembly which is loaded and unloaded as a unit in and out of the reactor.
Uranium is a radioactive element used to fuel nuclear reactors. It is a nuclear fuel.
