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
