ON bombarding uranium with neutrons, Fermi and collaborators 1 found ... elements in the middle of the periodic system. The whole 'fission' process can thus be described in an essentially ...

However, with a sufficient flux of hybrid-produced neutrons, the desired fissile fuel isotopes can be produced by neutron capture from the much more abundant non-fissile isotopes 238 U or 232 Th.

Fundamental studies of neutron capture and neutron-induced fission and applications relevant to astrophysics, nuclear medicine, stockpile stewardship, nuclear forensics, homeland security and nuclear ...

was a possible fission product according to her split uranium theory, but radium was not — it was too big (atomic mass = 226). When a neutron bombards a uranium atom, the uranium nucleus splits ...

Most new nuclear fission reactors being built today are of the light water reactor (LWR) type, which use water for neutron moderation into thermal neutrons as well as neutron capture. While ...

Nuclear fission close nuclear fissionThe splitting of a large nucleus to produce two smaller ones. Two or three neutrons are also released in the process. The energy from the neutrons powers a ...
