The core of a nuclear reactor comprises a central fuel zone, in which a fissile material normally constituted by a [mix] of enriched uranium oxide and plutonium oxide. This fuel zone is completely surrounded by a covering of fertile material normally constituted by depleted uranium oxide. In practice, this structure is obtained by juxtaposing vertical assemblies having a hexagonal section. Each of these assemblies comprises an outer tubular envelope, in which is placed a group or bundle of needles, each containing a pile of fissile and/or fertile material pellets. 1, record 1, English, - bundle%20of%20needles

Le réacteur surgénérateur, à neutrons rapides refroidi au sodium, ou filière RNR (réacteur à neutrons rapides). [...] Le combustible est constitué d'aiguilles, c'est-à-dire de fins crayons contenant de l'oxyde de plutonium et de l'oxyde d'uranium appauvri. (Uranium dont la teneur en isotope 235 est inférieure à la teneur naturelle de 0,7 %, donc formé essentiellement d'uranium 238. C'est le résidu de l'opération d'enrichissement de l'uranium.) En outre, des aiguilles ne contenant que de l'oxyde d'uranium constituent la couverture fertile. À partir de l'uranium 238 du cœur et de la couverture fertile, il se forme plus de plutonium qu'il n'en est consommé. 1, record 2, French, - oxyde%20d%27uranium%20appauvri
