Abstract

SE PRESENTA UN REACTOR DE ESCISION NUCLEAR COMBINADO CON UNA VALVULA DE DESPRESURIZACION Y/O DE INYECCION DE AGUA (38) ACTIVADA POR UN PROPULSOR. LA VALVULA DE DESPRESURIZACION LIBERA LA PRESION DE UN REACTOR NUCLEAR QUE PRODUCE VAPOR, REFRIGERADO CON AGUA CUANDO SE QUIERE ASEGURAR LA SEGURIDAD DEL REACTOR. LA DESPRESURIZACION DEL RECIPIENTE DE PRESION DEL REACTOR (14) PERMITE LA ALIMENTACION POR GRAVEDAD DE UN AGUA REFRIGERANTE SUPLEMENTARIA A TRAVES DE LA VALVULA DE INYECCION DE AGUA AL RECIPIENTE DE PRESION DEL REACTOR PARA EVITAR DAÑOS EN EL NUCLEO COMBUSTIBLE (16).
