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. 6, record 2, English, - neutron%20multiplication%20factor

Reactivity mechanisms change the value of the neutron multiplication factor in the reactor core. Most affect the parasitic absorption of thermal neutrons in the core. When a device increases the parasitic absorption in a core it is said to be adding negative reactivity. If a device is decreasing the parasitic absorption it is adding reactivity. 1, record 4, English, - neutron%20multiplication%20factor

Les mécanismes de contrôle de la réactivité changent la valeur du facteur de multiplication des neutrons dans le coeur du réacteur. La plupart d'entre eux ont une incidence sur l'absorption parasite des neutrons thermiques dans le coeur. Lorsqu'un dispositif augmente l'absorption parasite dans un coeur, on dit qu'il ajoute de la réactivité négative. On dit des dispositifs qui diminuent l'absorption parasite qu'ils ajoutent de la réactivité. 1, record 4, French, - facteur%20de%20multiplication%20des%20neutrons
