Abstract

Le support (100) comprend un élément (102) de base, de forme semsiblement carrée et monté sur le carter de verrouillage des mécanismes de commande des barres de controle pour empecher les déformations de ces mécanismes en cas de secousses sismiques. Les supports peuvent etre réglés à distance les uns par rapports aux autres à l'aide de tiges verticales (134) qui déplacent des blocs (130) de commande agissant sur des blocs (126) de réglage radialement mobiles. Un anneau entoure la périphérie du réseau de supports.
