Abstract

SYSTÈME D ’ ATTÉNUATION D ’ ACCIDENT DE GÉNÉRATEUR DE VAPEUR Un système d'atténuation d’accident de générateur de vapeur (1) est divulgué. Un système d'atténuation d'accident de générateur de vapeur (1) pour atténuer un accident si l'accident se produit dans un générateur de vapeur (50) installé à l'intérieur d'un bâtiment de confinement (100) d'une centrale nucléaire selon un exemple de mode de réalisation de la présente invention, le système (1) comprenant : un réservoir de pressurisation (10) qui est installé à l'intérieur du bâtiment de confinement (100) et comprend une première eau de refroidissement (11) et un gaz non condensable (13) pour pressuriser la première eau de refroidissement (11) qui s'y trouve ; au moins un tuyau de raccordement (30) reliant le générateur de vapeur (50) et le réservoir de pressurisation (10) ; et au moins une vanne de tuyau de raccordement (32, 34) qui est installée dans le au moins un tuyau de raccordement (30), respectivement, et qui est capable de contrôler le degré d'ouverture du tuyau de raccordement (30) ; dans lequel l'ouverture de la au moins une vanne de tuyau de raccordement (32, 34) permet une communication fluidique entre le générateur de vapeur (50) et le réservoir de pressurisation (10).
