Abstract

UN DISPOSITIVO DE FILTRADO PARA FILTRAR AGUA A UN SISTEMA DE ENFRIAMIENTO DE EMERGENCIA EN UNA PLANTA DE ENERGIA NUCLEAR CONTIENE UN AREA QUE TIENE UNA PIEZA INFERIOR QUE FORMA UN TANQUE EN LA QUE ESTA MONTADO EL DISPOSITIVO DE FILTRADO. EL DISPOSITIVO INCLUYE UN ALOJAMIENTO DE FILTRADO (1) CON PAREDES DE FILTRO SEPARADAS ENTRE LAS CUALES OPERA UNA UNIDAD DE PROTECCION FLEXIBLE (6). LA UNIDAD ESTA COLOCADA DE FORMA QUE PERMANEZCA EN UNA PRIMERA POSICION CUANDO EL AGUA SEA EXTRAIDA A TRAVES DE UNA DE LAS PAREDES DEL FILTRO, EN ESTA POSICION LE INTERRUMPE LA CONEXION ENTRE LA OTRA PARED DEL FILTRO Y UN CONDUCTO DE SUCCION (4). POR SU INHERENTE FLEXIBILIDAD, LA UNIDAD DE PROTECCION ES AUTOMATICAMENTE CONMUTADA HACIA UNA SEGUNDA POSICION QUE ABRE LA CONEXION ENTRE UNA SEGUNDA PARED DE FILTRO Y EL CONDUCTO DE SUCCION, TAN PRONTO COMO LA PRIMERA PARED DE FILTRO SE ATASCA POR IMPUREZAS DE UNA EXTENSION TAL QUE ORIGINA UNA BAJA PRESION EN EL ESPACIO ENTRE LA PRIMERA PARED DEL FILTRO Y LA UNIDAD DEELEMENTOS DE PROTECCION, ESTA BAJA PRESION TRAE CONSIGO LA SOBRECONMUTACION MEDIANTE SU EFECTO SUCCION.
