Yes, it is. Specific isotopes of plutonium can be used for nuclear fuel. An actinide is an element of the Periodic Table with an atomic number of 89 (actinium) or higher. Plutonium is atomic number 94. A link is provided.
Plutonium is an actinide
It is Uranium
Th, element 90, spelled thorium, is an actinide and has been used as a nuclear fuel (see Wikipedia.)
Plutonium is used as nuclear fuel for nuclear reactors to produce electric energy. Also plutonium is indispensable for nuclear weapons.
Plutonium
Yes, plutonium is a very important nuclear fuel.
Uranium and/or Plutonium fuel
Plutonium (as a metal or oxide , mixed oxide, carbide) can be used as nuclear fuel in nuclear reactors.
Plutonium (as dioxide, carbide, mixed oxides or carbides) is an important nuclear fuel for nuclear power reactors.
We look to the naturally occurring element uranium as a nuclear fuel.
Uranium and plutonium
Both uranium and plutonium are actinides that are used as nuclear fuel.
