[...] 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 2, French, - syst%C3%A8me%20RIC

The neutron flux monitoring system consists of two startup channels, two control channels and four safety channels. Typically, the safety channels are provided to monitor the ex-core neutron flux over the range of source power to full power of the nuclear reactor. Two startup channels provide source level range neutron flux information to a reactor operator. Two control channels provide neutron flux information, in the power operating range, to the reactor regulating system during automatic turbine load-following operations. 1, record 6, English, - startup%20channel
