In the case of a core containing 193 fuel assemblies, the use of in-core mobile instrumentation capable of examining 58 assemblies... using mobile probes introduced periodically into the nuclear reactor core is known. This instrumentation acts as the reference instrumentation. 1, record 1, English, - in%2Dcore%20mobile%20instrumentation

The thermal neutron flux of the reactor is monitored through the entire power range, from the source range level to 150% of full power(FP). Two types of instrumentation are used to cover this wide range :in-core and out-of-core instrumentation. The in-core instrumentation is composed of self-powered detectors, together with very small calibrating fission chambers(FC)(~3 mm in diameter). Out-of-core instrumentation is composed of ion chambers, BF3 and He3 detectors. 1, record 2, English, - out%2Dof%2Dcore%20instrumentation

[...] un système interne, mesurant le flux neutronique à l'intérieur du cœur, et un système externe placé à l'extérieur de la cuve coexistent. La terminologie habituellement retenue pour nommer les systèmes à partir de trigrammes utilise l'appellation RIC (réacteur instrumentation coeur) pour le premier et RPN (réacteur protection nucléaire) pour le second. Le système RIC mesure la distribution relative en 3D de la puissance à l'intérieur du cœur du réacteur avec une très bonne précision liée à un procédé de mesure interne au réacteur. C'est pourquoi on l'appellera par la suite système de référence. La constante de temps associée n'est pas une exigence forte; elle dépendra de l'architecture du système et de la technologie utilisée. 3, record 3, French, - syst%C3%A8me%20RIC
