Flux Oscillations. So far, we have assumed the flux distribution is static. Suppose now that without changing the total power of the reactor, the flux is increased in one region of the reactor. This typically results from refueling a channel. In the region of increased flux, the xenon now burns out more rapidly than it did before the change and its concentration decreases. This decrease in xenon concentration leads to a higher reactivity in this region, which, in turn, leads to another increase in flux. This again leads to increasing local xenon burnup, higher local reactivity, greater flux, and so on. 1, record 1, English, - flux%20oscillation

Oscillations du flux. Jusqu'ici, nous avons supposé que la distribution du flux est statique. Supposons maintenant que sans changer la puissance totale du réacteur, le flux soit augmenté dans une région du réacteur. Cela donne lieu habituellement à un rechargement de combustible dans un canal. Dans la région où le flux est plus élevé, le xénon subit une combustion plus rapide qu'avant le changement et sa concentration diminue. Cette diminution de la concentration de xénon cause une augmentation de la réactivité dans cette région, qui à son tour provoque une autre augmentation du flux. Cela peut donner lieu à une augmentation locale de la combustion de xénon, à une augmentation de la réactivité locale, à un flux plus élevé, et ainsi de suite. 1, record 1, French, - oscillation%20de%20flux
