"Fissile" means "capable of undergoing fission."
Fissile means that an isotope is capable of supporting a sustained nuclear chain reaction.
Fissile isotopes are isotopes of an element that can be split through fission
The isotopes 233U and 235U are fissile with thermal neutrons and the isotope 238U is fissile with fast neutrons.
Uranium-235 is the fissile isotope
Depleted Uranium
Uranium 235 is 0.7 percent of natural uranium and is fissile
In this type of nuclear reactor the fertile isotope thorium-232 is transformed in the fissile isotope uranium-233 and this act as a nuclear fuel.
Uranium (especialy the fissile isotope) 235U is fissionable by bombardments with thermal neutrons.
The fission energy of the fissile isotope uranium-235 is 1,68.10e8 kJ/mol.
Uranium-235 is a fissile isotope: can react with thermal neutrons (fission) to sustain a chain reaction.Thorium-232 is a fertile material: can absorb neutrons without fission and is transformed in the fissile isotope U-233.
Fuel used in a nuclear reactor is uranium, the active isotope is uranium 235 which is fissile.
Plutonium is a fissile isotope of plutonium; by fission Pu-241 release energy in nuclear reactors.
