Abstract

L'invention concerne un dispositif de verrouillage, notamment des sous-assemblages absorbants, et un réacteur nucléaire équipé d'un tel dispositif. Ledit dispositif de verrouillage comprend un ensemble d'encliquetage supporté par une enveloppe périphérique 20 d'un ensemble de barres de commande et comprenant un cliquet pivotant 23, 24 qui coopère avec une face 29 d'une structure 21 de support du coeur pour verrouiller ensemble l'enveloppe 20 et la structure 21, le mécanisme d'encliquetage comprenant une goupille de cisaillement destinée à céder sous une charge prédéterminée pour permettre de séparer l'enveloppe 20 de la structure 21. Application aux réacteurs nucélaires notamment surrégénérateurs refroidis par un métal liquide.
