Abstract
Dispositif de protection thermique d'une structure de réacteur nucléaire refroidi par un métal liquide, ladite structure comportant une paroi délimitant avec une virole parallèle présentant à son extrémité supérieure un bord libre formant seuil de déversoir, un espace s'étendant verticalement et parcouru selon le sens ascendant par un débit dérivé de métal liquide prélevé à partir d'un volume principal de ce métal liquide dans lequel plonge la partie inférieure de ladite paroi Selon l'invention, ladite virole comporte dans sa surface opposée audit espace, un empilement de toiles ou treillis métalliques, plaqué contre ladite surface de telle sorte que la lame déversante s'écoulant vers le bas en aval dudit seuil de déversoir, traverse ledit empilement avant d'être restituée dans ledit volume principal de métal liquide Application aux réacteurs neutrons rapides intégrés.
