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.
Well, as nuclear reactors are nuclear reactors, nuclear reactors are not used inside nuclear reactors.
Current nuclear reactors rely on nuclear fission as their nuclear reaction.
plutonium and uranium
We use nuclear fission in nuclear reactors to tap nuclear energy.
No, at least not for power reactors
radioactive element like uranium, plutonium......etc depends which type of nuclear reactor.
Basically, nuclear energy is used in two ways: * In nuclear reactors, to generate electricity. * In nuclear bombs (atom bombs) to cause destruction on a large scale.
There may be Radium, Thorium, Uranium or even Plutonium which can be used in nuclear reactors.
No substitute for nuclear power reactors especially if there is no available fossil fuel.
Nuclear reactors and nuclear weapons
No, nuclear fission operates all nuclear reactors. If they are power plant reactors it is used to generate electricity.
Pure Uranium is radioactive; thus harmful. Inside a nuclear reactor, atoms get split. When the Uranium atom is split, it releases a huge amount of energy. This energy is called nuclear energy. Also the normal Uranium is not used in reactors. The Uranium that is used is enhanced; it is an isotope of Uranium. Uranium-237 and Uranium-238 are used in nuclear reactors. I hope this answer was useful for you.
