Uranium and plutonium can be used as nuclear fuels for nuclear reactors.
Uranium
uranium
Fuel used in a nuclear reactor is uranium, the active isotope is uranium 235 which is fissile.
Typically, Uranium-235 is used as fuel in nuclear reactors.
The moderator used in nuclear reactors with natural uranium is generally the heavy water (D2O).
Uranium is the most common.
A nuclear reactor is a plant which deliver electricity and (or) heat.The function principle is the release of energy from nuclear fission of fissile materials as the isotope uranium-235.
Nuclear energy appears as heat in a nuclear reactor. It comes from the fission of uranium or plutonium
Depending on the type and the power of the nuclear reactor. An example; a CANDU type reactor of 700 MW need 700 kg uranium-235 and only ca. 500 kg are "burned".
The mass of uranium needed for a nuclear power reactor depend on the type and the power of this reactor. For a medium size reactor - 100 t.
Some nuclear power reactors work with low enriched uranium; CANDU reactors work with natural uranium.
