Abstract
La présente invention concerne un dispositif de sûreté à déclenchement passif pour réacteur nucléaire, le dispositif comprenant un assemblage comprenant : • un fourreau (200) destiné à être traversé longitudinalement par un fluide caloporteur ; • un équipage mobile (100), monté mobile en translation selon la direction longitudinale (3) dans le fourreau (200) et comprenant au moins une portion neutrophage ; l'équipage mobile (100) comprend une première portion de portance (110) et le fourreau (200) comprend une deuxième portion de portance (210), les première et deuxième portions de portance (110, 210) étant conformées de manière à ce que lorsque les première et deuxième portions de portance (110, 210) sont disposées en regard et que le débit Qf du fluide caloporteur traversant longitudinalement le fourreau (200) est supérieur à un débit Qdécienchement, alors le fluide caloporteur exerce sur l'équipage mobile (100) une force suffisante pour assurer la portance de l'équipage mobile dans le fourreau (200) et son maintien en configuration de portance et caractérisé en ce que la première (110) ou la deuxième (210) portion de portance forme un organe (112, 211) qui définit en partie au moins un amortisseur visqueux pour freiner la chute de l'équipage mobile 100 lors de sa chute.
