Uranium, plutonium or thorium (for fission reactors, by far the most common type).
Yes, plutonium is used as a fuel in nuclear reactors, specifically in certain types of reactors like fast breeder reactors and some types of advanced reactors. Plutonium-239, which is produced from uranium-238 in nuclear reactors, is a key fuel component due to its ability to sustain fission reactions.

Yes, plutonium is used as a fuel in certain types of nuclear reactors, such as breeder reactors. These reactors are designed to produce more plutonium than they consume, as a way to generate energy and also produce more fuel for future use.
No substitute for nuclear power reactors especially if there is no available fossil fuel.
Most reactors use uranium fuel enriched slightly to about 3-4 percent U-235, in the form of uranium dioxide UO2. Some older reactors used metallic natural uranium, while some other reactors use plutonium or a plutonium-uranium mix as fuel.
No, control rods are not a part of the fuel assemblies in nuclear reactors. They are separate "pieces" in the core, and essentially fit in "spaces" between fuel bundles.
Uranium is a radioactive element used to fuel nuclear reactors. It is a nuclear fuel.
Plutonium is used in nuclear power stations as a fuel in some types of reactors, like fast breeder reactors. It can undergo fission to produce energy. Additionally, plutonium can be created as a byproduct in nuclear reactors, which can then be reprocessed and reused as fuel.
The fuel in current reactors is all uranium. Usually enriched to 3% uranium-235.Someday part of the fuel might be plutonium, either recycled from bombs or made in breeder reactors. But not now.
Plutonium is used in nuclear reactors as a fuel because it can undergo fission, producing energy in the process. It is created as a byproduct in uranium-fueled reactors and can be recycled for use as fuel in mixed-oxide (MOX) fuel. Plutonium helps extend the fuel cycle and reduce waste by utilizing more of the energy content in nuclear fuel.
