Abstract

UNA PLANCHA DE CONEXION INFERIOR MEJORADA (L) QUE TIENE RESISTENCIA AL FLUJO DE FLUIDO, SE DIFUNDE PARA USO EN UN REACTOR NUCLEAR DE AGUA EN EBULLICION. EL PAQUETE DE COMBUSTIBLE INCLUYE LA PLANCHA DE CONEXION INFERIOR, UNA PLANCHA DE CONEXION SUPERIOR, Y UNA VARIEDAD DE VARILLAS DE COMBUSTIBLE (R) SOPORTADAS ENTRE SI, EN RELACION DE POSICION VERTICAL. LAS VARILLAS DE COMBUSTIBLE ESTAN RODEADAS POR UN CANAL QUE CONFINA EL FLUJO DE FLUIDO A TRAVES DEL PAQUETE DE COMBUSTIBLE, ENTRE LAS PLANCHAS DE CONEXION PARA LA EXTRACCION DE CALOR DE LAS VARILLAS DE COMBUSTIBLE QUE SUFREN UNA REACCION DE FISION. LA PLANCHA DE CONEXION INFERIOR INCLUYE UN PRIMER GRUPO DE LOCALIZACIONES DE APOYO PARA LAS VARILLAS DE COMBUSTIBLE EN POSICIONES SELECCIONADAS EN UNA MATRIZ. LA MATRIZ SE PUEDE INTERRUMPIR EN ABERTURAS MAS GRANDES, PARA EL APOYO DEL MODERADOR QUE CONTIENE VARILLAS HIDRAULICAS. LA PLANCHA DE CONEXION INCLUYE IGUALMENTE UNA SEGUNDA MATRIZ DE ORIFICIOS A TRAVES DE LA MISMA (70) QUE ACTUAN COMO ORIFICIOS DE DISIPACION DE ENERGIA. ESTOS ORIFICIOS DE DISIPACION DE ENERGIA DEL FLUIDO INCLUYEN UNA PEQUEÑA ABERTURA DE RECEPCION DEL FLUIDO EXPUESTA HACIA ABAJO, QUE DESCARGA A UN AREA MAS GRANDE DE FLUJO EXPUESTA HACIA ARRIBA, FORMADA PREFERIBLEMENTE CON LA ESTRUCTURA DE UNA ABERTURA CONCENTRICA. EN EL MONTAJE PREFERIDO, LA ENTRADA A LA PRIMERA ABERTURA PEQUEÑA Y CONCENTRICA DE RECEPCION DE FLUIDO EXPUESTA HACIA ABAJO, ES REDONDEADA PARA LA ADMISION DE FLUIDO CON MAXIMA PREDICCION DE FLUJO. LA TRANSICION ENTRE LAS DOS ABERTURAS PRODUCE TURBULENCIA DE DISIPACION DE ENERGIA, PREDECIBLE EN EL AREA DE DESCARGA DE FLUIDO EXPUESTA HACIA ARRIBA. EL PASO DEL FLUIDO A TRAVES DE LAS ABERTURAS DE DISIPACION DE ENERGIA PRODUCE UNA CAIDA DE PRESION AUMENTADA EN LA PLANCHA DE CONEXION INFERIOR, PARA LA SUPRESION DE INESTABILIDADES DEL FLUJO TERMO-HIDRAULICO, E INESTABILIDADES NUCLEARES TERMO-HIDRAULICAS ACOPLADAS. ESTA PRESENTE UN EFECTO DESCUBIERTO POR CASUALIDAD, EN EL QUE LA CAIDA DE PRESION MEJORADA PRODUCE FLUJO DE FLUIDO UNIFORME EN EL INTERIOR DEL PAQUETE DE COMBUSTIBLE INMEDIATO A LA PLANCHA DE CONEXION INFERIOR
