Abstract

L'invention concerne un bouchon d'enveloppe de coeur de réacteur nucléaire pouvant etre installé dans un orifice (42) de l'enveloppe (28). Le bouchon comporte un corps (52) avec des ouvertures légèrement coniques et une partie cylindrique (60) dilatable dans laquelle est disposé un mandrin mobile (54). L'application d'un fluide sous pression fait avancer le mandrin (54) en dilatant le corps (52) en appui contre la surface intérieure de l'orifice (42). Le bouchon comporte également un mécanisme de blocage (86) pour éviter toute libération accidentelle du bouchon.
