Abstract

Un conjunto (25) de modulo de potencia configurado para su uso en una central nuclear, comprendiendo la central nuclear una piscina (46) de refrigeración de contención, comprendiendo el conjunto (25) de modulo de potencia: una vasija (42) de reactor que contiene un núcleo (6) de reactor rodeado por un refrigerante primario (100); un intercambiador (55) de calor en contacto con el refrigerante primario (100), estando configurado el intercambiador (55) de calor para eliminar calor generado por el nudeo (6) del reactor; una vasija (44) de contend& que esta configurada para estar sumergida en la piscina (46) de refrigeraci6n de contencion, en la que la vasija (44) de contención esta configurada para prohibir la liberaciOn de refrigerante primario (100) fuera de la vasija (44) de contención; uno o mas orificios (54) de entrada que estan configurados para estar sumergidos en la piscina (46) de refrigeración de contención, donde los uno o mas orificios (54) de entrada estan configurados para absorber agua de alinnentación de emergencia de la piscina (46) de refrigeración de contención durante una operacion de emergencia; y una o mas valvulas (58) de salida que estan configuradas para desgasificar el agua de alimentacion de emergencia en la piscina (46) de refrigeracion de contender' durante la operación de emergencia; en el que el conjunto (25) de modulo de potencia esta configurado para permitir que el agua de alimentación de emergencia circula desde la piscina (46) de refrigeración de contención por el intercambiador (55) de calor mediante circulación natural para eliminar el calor generado por el núcleo (6) del reactor durante la operación de emergencia, y en el que no se permite que el agua de alimentacion de emergencia se mezcle con el refrigerante primario (100) durante la operación de emergencia.
