Abstract

SE DISPONE UNA CUBETA (34) DE SISTEMA DE ENFRIAMIENTO ACCIONADO POR GRAVEDAD EN UN LUGAR ELEVADO CON RESPECTO A LAS UBICACIONES DE BARRAS DE COMBUSTIBLE NUCLEAR EN UN DEPOSITO EN PRESION (12) EN UN CONFINAMIENTO (14). EN EL CASO DE UNA PERDIDA DE FLUIDO REFRIGERANTE EN EL DEPOSITO EN PRESION, LA PRESION DEL VAPOR SE REDUCE INICIALMENTE VENTILANDO (20) EL VAPOR DENTRO DEL CONFINAMIENTO O DE UNA CUBETA DE SUPRESION CERRADA (28) QUE CONTENGA UNA CANTIDAD DE AGUA (24) BAJO UN GRAN ESPACIO DE AIRE (26). LA CUBETA DE SUPRESION CONDENSA SUFICIENTE VAPOR PARA REDUCIR LA PRESION DEL VAPOR EN EL DEPOSITO EN PRESION DE FORMA QUE EL AGUA PUEDA CIRCULAR POR GRAVEDAD DESDE LA CUBETA DEL SISTEMA DE ENFRIAMIENTO ACCIONADO POR GRAVEDAD PARA INUNDAR LAS BARRAS DE COMBUSTIBLE EN EL DEPOSITO EN PRESION. UN CONDENSADOR DE AISLAMIENTO (40) SE SUMERGE EN UN GRAN SUMINISTRO DE AGUA (50) ELEVADO CON RESPECTO AL DEPOSITO EN PRESION. SE DEJA PASAR EL VAPOR AL CONDENSADOR DE AISLAMIENTO, O INTECAMBIADOR DE CALOR, DONDE ES ENFRIADO HACIENDO QUE HIERVA EL AGUA QUE LO RODEA. ESTE VAPOR SE VENTILA EN LA ATMOSFERA. UNA VALVULA DE DESPRESURIZACION (32) VENTILA EL VAPOR DESDE EL DEPOSITO EN PRESION AL CONFINAMIENTO PARA AYUDAR A LA REDUCION DE LA PRESION, Y ASI AYUDAR A LA CIRCULACION POR GRAVEDAD DEL FLUIDO REFRIGERANTE. DESPUES, CUANDO LA PRESION DEL DEPOSITO EN PRESION SE REDUCE MEDIANTE ELIMINACION DEL CALOR EN EL CONDENSADOR DE AISLAMIENTO, SE PERMITE QUE EL VAPOR EN EL CONFINAMIENTO CIRCULE DESDE EL CONFINAMIENTO A TRAVES DE LA VALVULA DE DESPRESURIZACION (32) Y DESDE AQUI AL CONDENSADOR DE AISLAMIENTO, O INTERCAMBIADOR DE CALOR.
