a fissile isotope that could be nuclear reactions, was slightly less than that which typically found in natural uranium. It baffled scientists of a time because all the natural uranium was to have ...

Normally, natural uranium has 0.72% of the uranium-235 (U-235) isotope, which is sought in the nuclear fission process. However, the Oklo samples possessed a ... This has greatly assisted in ...

The heat-generating chain reaction inside a nuclear power station takes place under highly controlled conditions within the reactor core. Uranium-235 atoms can spontaneously break-apart (fission) ...

Nuclear fusion and nuclear fission are two fundamental nuclear reactions that release energy ... collides with an unstable nucleus, such as uranium-235. This causes the nucleus to break apart ...
