Abstract
Agencement pour maintenir la capacité de fonctionnement de joints plongeants situés dans les couronnes autour des bouchons tournants associés à la tête de fermeture de la cuve d'un réacteur nucléaire étudié pour contenir des matériaux radioactifs, caractérisé par ceci qu'au moins un transducteur ultrasonique 72 est monté de telle sorte sur cette tête de fermeture 24-30 qu'il air sa surface émettrice de vibrations disposée de manière à diriger ces vibrations vers ces joints plongeants 56 pour détacher les dépôts d'impuretés de ces derniers et pour déterminer le mouillage des surfaces de métal de ces joints plongeants 56. Application aux réacteurs nucléaires.
