Abstract

APARATO Y PROCESO QUE UTILIZA UNA GRAN BARRA DE AGUA DE UN HAZ COMBUSTIBLE EN EL SISTEMA DE COMBUSTIBLE DE UN REACTOR DE AGUA HIRVIENDO COMO SUMIDERO DE CALOR RADIANTE DURANTE UN INCIDENTE DE PERDIDA DE REFRIGERANTE. LA PULVERIZACION DE REFRIGERACION DEL NUCLEO SE RECOGE EN EL EXTREMO SUPERIOR DE LA GRAN BARRA DE AGUA DE UN HAZ COMBUSTIBLE MEDIANTE UN COLECTOR Y SE DISTRIBUYE POR UN DISTRIBUIDOR PARA RECUBRIR LAS SUPERFICIES DE LAS PAREDES INTERIORES DE LAS BARRAS DE AGUA. EN CASO DE QUE LA BARRA NO TENGA VENTILACION EN SU PARTE INFERIOR, SE MODIFICA SU CUERPO PARA SEPARAR LA CORRIENTE DESCENDENTE DE AGUA LIQUIDA DE LA CORRIENTE ASCENDENTE DE VAPOR. DURANTE EL FUNCIONAMIENTO NORMAL DE LA PLANTA, LA BARRA DE AGUA SIRVE COMO TUBO MODERADOR LLENO DE AGUA PARA PROPORCIONAR UNA DISTRIBUCION DE ENERGIA MAS UNIFORME POR TODO EL HAZ COMBUSTIBLE
