Abstract

Condenseur de secours pour générateur de vapeur L’invention a pour objet un condenseur 3 SACO pour générateur de vapeur 2 d’un réacteur, comprenant : un échangeur de chaleur comprenant une calandre 300, un système de régulation 31 de l’alimentation en eau tertiaire de l’échangeur. Le système de régulation 31 comprend avantageusement :un obturateur 310 configuré pour réguler un débit d’eau tertiaire en amont de l’entrée de la calandre 300. Cet obturateur est relié d’une part à un flotteur 311 configuré pour mouvoir l’obturateur en fonction d’un niveau d’eau tertiaire dans la calandre 300, de façon à réguler le débit selon un mode passif, et d’autre part à un dispositif électromécanique 312 configuré pour mouvoir ledit obturateur indépendamment du niveau d’eau tertiaire dans la calandre 300, de façon à réguler le débit selon un mode actif. L’invention a également pour objet un système de régulation pour SACO, une centrale nucléaire équipée d’un condenseur SACO est un procédé de fonctionnement d’un condenseur SACO. Figure pour l’abrégé : Fig.2AEmergency condenser for a steam generator The subject of the invention is a SACO condenser 3 for a steam generator 2 of a reactor, comprising: a heat exchanger comprising a shell 300, a system for regulating the tertiary water supply of the exchanger. The regulation system 31 advantageously comprises: a shutter 310 configured to regulate a tertiary water flow upstream of the inlet of the calender 300. This shutter is connected on the one hand to a float 311 configured to move the shutter in function of a tertiary water level in the shell 300, so as to regulate the flow in a passive mode, and on the other hand to an electromechanical device 312 configured to move said shutter independently of the tertiary water level in the shell 300, so as to regulate the flow according to an active mode. The invention also relates to a control system for SACO, a nuclear power plant equipped with a SACO condenser is a method of operating a SACO condenser. Figure for the abstract: Fig.2A
