Abstract

Système automatique d'arrêt de réacteurs nucléaires. Le système comprend un assemblage 16 de commande de la réactivité comportant un élément 42 d'absorption des neutrons mobile entre une position haute et une position basse, et un système 28 sensible à la température et formant un mécanisme de verrouillage, prévu pour maintenir le faisceau 42 en position haute mais pour libérer l'élément d'absorption quand la température détectée est supérieure à une température donnée. Un passage 68 d'écoulement se prolonge vers le bas jusqu'à un moyen 54 de pompage disposé à la partie inférieure de l'assemblage, de sorte que la température du fluide chauffé de refroidissement venant d'au-dessus de l'assemblage peut être détectée directement par un moyen 62 sensible à la température. Applications : notamment aux réacteurs nucléaires refroidis par métal liquide. (CF DESSIN DANS BOPI)
