Abstract

SYSTEME ET PROCEDE DE REDUCTION DU DEGAGEMENT ATMOSPHERIQUE DE MATIERES RADIOACTIVES PROVOQUE PAR UN ACCIDENT GRAVE L’invention concerne un système et un procédé de réduction du dégagement atmosphérique de matières radioactives provoqué par un accident grave. Le système inclut un générateur de vapeur disposé dans une enceinte de confinement, configuré pour générer de la vapeur par l’utilisation de chaleur provenant d’un caloporteur chauffé dans un réacteur nucléaire, et raccordé à une turbine par le biais d’une ligne de vapeur principale, une cuve de décontamination raccordée à la ligne de vapeur principale par le biais d’une ligne de raccordement et contenant de l’eau de décontamination pour décontaminer la vapeur délivrée par le générateur de vapeur et réduire le dégagement atmosphérique de matières radioactives quand un accident grave se produit, et une unité de génération d’énergie de dépressurisation disposée sur la ligne de raccordement et configurée pour générer de l’énergie d’urgence tout en dépressurisant la vapeur délivrée par le générateur de vapeur vers la cuve de décontamination lorsque l’accident grave se produit.
