Abstract

La présente invention concerne une centrale à cycle combiné dotée d'une fonction de secours au démarrage et en cours de fonctionnement, qui maintient de façon sûre un refroidissement par vapeur en cas d'accident. La centrale à cycle combiné de l'invention maintient de façon sûre un refroidissement par vapeur de la façon suivante: lorsqu'une vapeur d'échappement en provenance d'une turbine haute pression (301), qui constitue la vapeur de refroidissement d'un système de refroidissement par vapeur (400), diminue soudainement, elle amène dans le système de refroidissement par vapeur (400), qui permet de refroidir par la vapeur une partie à haute pression d'une turbine à gaz, une vapeur à haute ou à moyenne pression en provenance d'une chaudière de récupération de chaleur des gaz d'échappement (200) afin de l'utiliser comme vapeur de refroidissement.
