Nuclear . fuel is any material that can be consumed to derive nuclear energy. The most common type of nuclear fuel is fissile elements that can be made to undergo nuclear fission chain reactions in a nuclear reactor . Large nuclei split into 2 smaller more stable nuclei. Sometimes natural. Most of the time extra energy is needed. Usually neutrons are released . Released neutrons may then hit other nuclei causing a . Ian Gauld. Marco Pigni.

Evaluated decay data have major importance to areas of reactor safety and nuclear fuel cycle analysis.
