Abstract

A FIN DE REDUCIR LA RESISTENCIA AL FLUJO DEL REFRIGERANTE QUE CIRCULA A TRAVES DE UN CONDUCTO (63) DE LA PLACA DE APOYO (64) DE UN REACTOR DE AGUA EN EBULLICION Y QUE ACCEDE A LA PIEZA DE TRANSICION (50) EN EL EXTREMO INFERIOR DE UN CONJUNTO DE COMBUSTIBLE QUE DESCANSA SOBRE DICHA PLACA DE APOYO (64), EL CONTORNO INFERIOR (60) DE LA PIEZA DE TRANSICION (50) ADOPTA LA FORMA DE UNA SUPERFICIE CONICA QUE AJUSTA EN LA CORRESPONDIENTE CONTRASUPERFICIE (62), TAMBIEN CONICA, DEL BORDE SUPERIOR DE DICHO CONDUCTO. EL CONTORNO INFERIOR (60) DE LA PIEZA DE TRANSICION (50) CONSTITUYE UNA ENTRADA CIRCULAR, CONCENTRICA CON EL CONDUCTO (63), Y TIENE UN TAMAÑO IGUAL O LIGERAMENTE MAYOR QUE LA ABERTURA DEL CONDUCTO. UNOS DEDOS (70) SOBRESALEN LATERALMENTE EN DICHA ABERTURA Y SE EXTIENDEN HACIA ABAJO EN EL CONDUCTO (63) PARA CENTRAR EN EL EL CONTORNO INFERIOR (60). ADEMAS, LOS EXTREMOS (90) DE LAS VARILLAS DE COMBUSTIBLE PUEDEN ADOPTAR UNA FORMA PERFILADA Y SE PUEDE SEPARAR LA PLACA INFERIOR DE UNION (53) DEL CONJUNTO DE COMBUSTIBLE RESPECTO A LA SUPERFICIE INTERIOR DEL CANAL DE COMBUSTIBLE (52), MEDIANTE VARIOS REFUERZOS (86) QUE DETERMINAN VARIOS ORIFICIOS PASANTES PERIFERICOS (86 ) EN CADA UNA DE LAS CUATRO SUPERFICIES INTERIORES (84) DEL CANAL RECTANGULAR DE COMBUSTIBLE (52).
