We mine uranium for use as a nuclear fuel. The uranium is separated from ore, and may undergo enrichment to separate out the lighter U-235 nuclide from the heavier U-238 one.
Uranium is a radioactive element used to fuel nuclear reactors. It is a nuclear fuel.
To make fuel rods for nuclear reactors
Uranium (U) Or Plutonium (Pu)
We look to the naturally occurring element uranium as a nuclear fuel.
It is either mined or synthesized, though usually mined, as this is much less expensive. Some reactors (such as the CANDU) can even use the waste from other reactors, without any refinement at all.
Any fissile material would do, but Uranium is the most common.
Plutonium is a chemical element, radioactive, solid, metal, artificial (but exist also as a natural element in extremely low concentrations in uranium ores). Plutonium is essential for nuclear reactors (as fuel) and for nuclear weapons (as explosive).
No substitute for nuclear power reactors especially if there is no available fossil fuel.
Uranium and/or Plutonium fuel
yes
Nuclear reactors.
Uranium is the main fuel used, but in some countries a mixture of uranium and plutonium is also used (MOX fuel)
