Title
(EN) FUEL ASSEMBLY TRANSPORTATION CONTAINER AND TOP CAPPING DEVICE THEREOF
(FR) CONTENEUR DE TRANSPORT D'ASSEMBLAGE COMBUSTIBLE ET SON DISPOSITIF DE CAPSULAGE SUPÉRIEUR

Abstract
(EN)
Disclosed are a fuel assembly transportation container and a top capping device thereof. The top capping device comprises a door sheet (2221) used for covering the upper end of the cavity of the transportation container, and a locking structure mounted on the door sheet (2221) for axially locking a fuel assembly (3) in the transportation container (4). The locking structure comprises a first locking bar (2222) and second locking bars (2223), which are mounted with adjustable axial positions on the door sheet (2221); the first locking bar (2222) is located in the middle of the door sheet (2221) and is opposite to the center of an upper tube socket of the fuel assembly (3); and at least two second locking bars (2223) are arranged, central symmetrically, at the circumference of the first locking bar (2222). With no need to dismount the door sheet (2221), the first locking bar (2222) and the second locking bars (2223) of the locking structure can be respectively and independently adjusted, so as to press out the fuel assembly (3) with or without related components for multiple functions. The device can be conveniently operated and easily maintained.
(FR)
L'invention concerne un conteneur de transport d'assemblage combustible et son dispositif de capsulage supérieur. Le dispositif de capsulage supérieur comprend une feuille de porte (2221) utilisée pour recouvrir l'extrémité supérieure de la cavité du conteneur de transport, et une structure de verrouillage montée sur la feuille de porte (2221) pour verrouiller axialement un assemblage combustible (3) dans le conteneur de transport (4). La structure de verrouillage comprend une première barre de verrouillage (2222) et des secondes barres de verrouillage (2223), qui sont montées avec des positions axiales réglables sur la feuille de porte (2221) ; la première barre de verrouillage (2222) est située au milieu de la feuille de porte (2221) à l'opposé du centre d'une douille de tube supérieure de l'assemblage combustible (3) ; et au moins deux secondes barres de verrouillage (2223) sont agencées, de manière symétrique, au niveau de la circonférence de la première barre de verrouillage (2222). Sans avoir besoin de démonter la feuille de porte (2221), la première barre de verrouillage (2222) et les secondes barres de verrouillage (2223) de la structure de verrouillage peuvent être respectivement et indépendamment réglées, de façon à presser l'assemblage combustible (3) avec ou sans composants associés pour de multiples fonctions. Le dispositif fonctionne de manière pratique et est facile à entretenir.
