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 2, English, - neutron%20flux%20measuring%20instrumentation

The Movable In-Core Instrumentation System is an automated, three-dimensional method of measuring reactor core neutron flux density. Flux maps are produced by successively passing a neutron-sensitive detector axially through the reactor core.  2, record 3, English, - movable%20in%2Dcore%20instrumentation%20system

To obtain a more exact representation of the neutron flux distribution within the core, additional neutron flux measurements are conducted within the core... Each incore probe is fixed to the end of a flexible cable referred to as a teleflex cable for moving it inside a measuring channel of the instrumentation of the nuclear reactor. Each measuring channel opens at one end into an instrumentation area in the bottom part of the reactor building. The fission probes are moved inside the measuring channels from the instrumentation area. Each measuring channel includes a fuel assembly instrumentation tube inside the core of the nuclear reactor and a glove finger inside the instrumentation tube in which the fission probe moves. The neutron flux is measured in a set of fuel assemblies distributed throughout the section of the core.  1, record 4, English, - instrumentation%20tube
