Abstract

UN SISTEMA DE FILTRO PARA FILTRAR AGUA A UN SISTEMA DE REFRIGERACION DE EMERGENCIA EN UNA PLANTA DE ENERGIA NUCLEAR INCLUYE UNA ESTRUCTURA O TUBO (4) QUE TIENE UNA PARED DE FILTRO CON ABERTURAS O PERFORADA A TRAVES DE LA CUAL EL AGUA PUEDE FLUIR DESDE EL EXTERIOR HASTA EL INTERIOR DE LA ESTRUCTURA EN RELACION CON EL FILTRADO REGULAR DEL AGUA INTRODUCIDA EN SU INTERIOR. UN DEPOSITO ACUMULADOR RECEPTOR DE AGUA (7) ESTA CONECTADO CON UNA CAVIDAD DE LA ESTRUCTURA DEL FILTRO, Y UNA FUENTE DE GAS A PRESION ESTA CONECTADA CON EL DEPOSITO PARA, SI SE REQUIERE, ALIMENTAR EL GAS A PRESION DENTRO DEL DEPOSITO PARA FORZAR MOMENTANEAMENTE AL AGUA A SALIR DE AHI Y ENTRAR EN LA CAVIDAD DE LA ESTRUCTURA DEL FILTRO MIENTRAS ES EXPULSADA POR DETRAS.
