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 cœur d'un réacteur est constitué d'assemblages verticaux de section hexagonale ou carrée. Chacun de ces assemblages comprend un faisceau d'aiguilles combustibles ou «éléments combustibles» contenant chacun un empilement de pastilles du matériau à base d'actinide. Le réfrigérant (sodium ou eau) circule autour de chaque élément combustible.  2, record 1, French, - faisceau%20d%27aiguilles

The Windscale Pile 1 is a graphite moderated, air-cooled, horizontal, natural uranium fuelled reactor. In October 1957, during a graphite annealing operation, the core temperature unexpectedly increased-resulting in a large fuel fire.  1, record 2, English, - graphite%20annealing

A temporary casing and core are driven together, the core is removed and the casing filled with concrete, then the core is replaced on the concrete and the casing withdrawn, leaving the weight of about 7 tons of hammer and plunger on the concrete. This type of pile is known as the MacArthur straight-shaft pile.  1, record 4, English, - MacArthur%20straight%2Dshaft%20pile

Un tube provisoire est battu avec un mandrin intérieur, on enlève le mandrin et on remplit le tube de béton. Ensuite, on place à nouveau le mandrin sur le béton et on retire le tube, en laissant un poids de 6 tonnes sur le béton. Ce type de pieux est connu sous le nom de «MacArthur straight-shaft piles» pieux MacArthur à fût cylindrique.  1, record 4, French, - pieu%20MacArthur%20%C3%A0%20f%C3%BBt%20cylindrique

Cobi pneumatic mandrel piles are formed by driving a constant-diameter thin corrugated metal shell by an internal mandrel, which is of smaller diameter than the pile when placed in the shell but is then expanded, to grip the pile, by gas applied under high pressure to a central flexible core.  1, record 5, English, - Cobi%20pneumatic%20mandrel%20pile

Pieux à mandrins pneumatiques Cobi. - Ils sont constitués par une chemise en tôle ondulée, de diamètre constant, battue à l'aide d'un mandrin intérieur. Ce mandrin a un diamètre inférieur à celui du pieu lorsqu'on le descend dans la chemise. Puis, on le dilate pour qu'il agrippe la chemise, en appliquant un gaz sous pression au noyau central flexible.  1, record 5, French, - pieu%20%C3%A0%20mandrins%20pneumatiques%20Cobi
