Method of installing a sleeve within an instrumentation tube of a nuclear fuel assembly. A spacer sleeve is installed within an instrumentation tube of a nuclear fuel assembly comprising two end nozzles connected by tie rods and a plurality of fuel rod supporting grids distributed at axial intervals along the tie rods. The instrumentation tube has a first end received in an initially blind bore formed in one of the end nozzles and communicating with the outside by a coolant restriction.  1, fiche 1, Anglais, - instrumentation%20tube

Il est nécessaire de calculer la section efficace de fission pour pouvoir remonter au flux reçu par le détecteur. Les modèles théoriques utilisés doivent être capables de modéliser explicitement le doigt de gant et le tube d'instrumentation afin de représenter les conditions exactes de la mesure.  1, fiche 2, Français, - tube%20d%27instrumentation

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, fiche 3, Anglais, - instrumentation%20tube
