  • Atomic Physics
DEF

The average number of neutrons that go on to cause another fission reaction.

OBS

The remaining neutrons either fail to induce fission, or are never absorbed and exit the system. The value of k for a combination of two masses is always greater than of its components. In some cases its value is equal to the sum of the component k values. The magnitude of the difference depends on velocity and distance, as well as physical orientation.

French

Domaine(s)

Un accident de criticité survient lorsque le coefficient de multiplication des neutrons (k eff, rapport entre le nombre de neutrons produits par fission et le nombre de neutrons disparaissant par capture ou par fuite hors du système considéré) dans un milieu fissile devient supérieur à 1.
