Abstract
Une zone à faible vitesse au-dessus de la plate-forme primaire dans un générateur de vapeur nucléaire de recirculation est formée, à travers laquelle s'écoule un faible pourcentage de liquide recyclé. L'écoulement de liquide est établi par des orifices d'entrée et de sortie qui sont dimensionnés et positionnés de manière stratégique. Des particules en suspension à l'intérieur de la zone à faible écoulement se déposent sur la plate-forme de pont primaire horizontale et sont ainsi éliminées de l'écoulement recirculé.
