To make fuel rods for nuclear reactors
Uranium is used
The question should not be, what element, but what isotope. Several easily fissible isotopes are used, such as Uranium-235. But note that the element Uranium as such is not usable - only that specific isotope.
Uranium is the only naturally occurring element used for nuclear fission in commercial nuclear reactors. It is typically found in two isotopes, uranium-235 and uranium-238, with uranium-235 being the primary isotope used for nuclear fission reactions.

Uranium is a radioactive element commonly used in nuclear power stations. It undergoes nuclear reactions to produce heat, which is then used to generate electricity.
Fluorine is not a component of uranium itself; rather, it is a separate element. However, uranium can form compounds with fluorine, such as uranium hexafluoride (UF6), which is used in the uranium enrichment process for nuclear fuel. In this context, fluorine plays a role in the chemistry of uranium but is not inherently found in uranium as an element.
Uranium is an actinoid series element.
Uranium-235 is the element with a mass number of 235. It is a radioactive isotope of uranium that is used in nuclear reactors and nuclear weapons.
Uranium is a radioactive element used to fuel nuclear reactors. It is a nuclear fuel.
