Abstract

Un mécanisme d'entraînement de tige de commande comprenant un ensemble de coque d'étanchéité, un boîtier mobile fixement raccordé à l'ensemble de coque d'étanchéité, un ensemble de bobine emmanché sur l'ensemble de coque d'étanchéité, et un ensemble de crochet disposé dans l'ensemble de coque d'étanchéité, dans lequel l'ensemble de coque d'étanchéité comprend une coque d'étanchéité et une base de tube, et la coque d'étanchéité et la base de tube forment une structure solidaire. La structure solidaire supprime le processus pour souder la base de tube sur la coque d'étanchéité. De cette manière, le temps pour fabriquer et assembler le réacteur dans son ensemble peut être économisé. Egalement, par rapport à l'art antérieur, le réacteur utilisant un tel procédé réduit une soudure nucléaire lisse, réduisant le risque de fuite. En somme, la structure décrite ci-dessus prolonge la durée de vie du mécanisme d'entraînement de tige de commande et réduit considérablement le travail pour le contrôle en service du mécanisme d'entraînement de tige de commande.
