The operation of a nuclear reactor is usually monitored by neutron flux measuring instrumentation introduced into the core. This instrumentation consists of detectors which can be moved into different sites in the fuel charge during operation of the reactor. The detectors are connected to flux measuring apparatus situated in a measuring room inside the shielding enclosure. They are generally moved inside a plurality of guide tubes which penetrate into the core and which are closed at the end. 1, record 5, English, - neutron%20flux%20measuring%20instrumentation

During normal, long-term operation, the exposure of the fuel to neutrons varies from place to place in the reactor. The fuelling engineer selects fuel replacement times and places to even out the availability of neutrons across the core. This is known as neutron flux flattening. The oldest fuel, which absorbs many neutrons uselessly, is left longer in areas of the core where the neutron flux tends to be high. Fresh fuel, which gives a higher rate of fission per neutron, is inserted into regions where the neutron flux is lower. 1, record 10, English, - neutron%20flux%20flattening

Combustible appauvri et aplanissement du flux neutronique. [...] En cours de fonctionnement normal, sur une longue période, l'exposition du combustible aux neutrons varie d'un endroit à l'autre du réacteur. Pour égaliser la disponibilité des neutrons dans le coeur, l'ingénieur responsable de son alimentation choisit le moment où l'on remplacera des grappes et dans quel emplacement les insérera-t-on. Ce travail s'appelle l'aplanissement du flux. Parce que le combustible plus vieux absorbe inutilement un grand nombre de neutrons, on le laisse plus longtemps dans les régions du coeur où le flux de neutron est spontanément plus élevé. On insère le combustible frais, dont le nombre de fissions par neutron est plus élevé, dans les régions où le flux de neutron est moins élevé. 1, record 10, French, - aplanissement%20du%20flux%20neutronique
